DikuMud has been created by the above five listed persons in their spare time, at DIKU (Computer Science Instutute at Copenhagen University). You are legally bound to follow the rules described in this document. Rules: !! DikuMud is NOT Public Domain, shareware, careware or the like !! You may under no circumstances make profit on *ANY* part of DikuMud in any possible way. You may under no circumstances charge money for distributing any part of dikumud - this includes the usual $5 charge for "sending the disk" or "just for the disk" etc. By breaking these rules you violate the agreement between us and the University, and hence will be sued. You may not remove any copyright notices from any of the documents or sources given to you. This license must *always* be included "as is" if you copy or give away any part of DikuMud (which is to be done as described in this document). If you publish *any* part of dikumud, we as creators must appear in the article, and the article must be clearly copyrighted subject to this license. Before publishing you must first send us a message, by snail-mail or e-mail, and inform us what, where and when you are publishing (remember to include your address, name etc.) If you wish to setup a version of DikuMud on any computer system, you must send us a message , by snail-mail or e-mail, and inform us where and when you are running the game. (remember to include your address, name etc.) Any running version of DikuMud must include our names in the login sequence. Furthermore the "credits" command shall always cointain our name, addresses, and a notice which states we have created DikuMud. You are allowed to alter DikuMud, source and documentation as long as you do not violate any of the above stated rules. Regards, The DikuMud Group Note: We hope you will enjoy DikuMud, and encourage you to send us any reports on bugs (when you find 'it' time to write and improve DikuMud, bugs, etc. - and changes will take their time. We have so far put extremely many programming hours into this project. If you make any major improvements on DikuMud we would be happy to hear from you. As you will naturally honor the above rules, you will receive new updates and improvements made to the game |

I'll get it started by replying to something Emil wrote in another thread. He wrote:
Quote:
I've been advised, by an expert, that the DIKU license is so seriously flawed it won't hold up, but of course, one can find experts to put forth nearly any opinion. That's why we have the civil court system: Because there can be -legitimate- disagreement about issues like this. Both sides can legitimately and ethically believe they are correct. A judge then decides who will is correct under the eyes of the law, and, pending appeals of course, that's that. All I'm saying is that this is a very complicated issue, and to ignore all that we don't know about IP law is to really over-simplify. Quote:

So, as for the so-called moral/ethical issue around the DIKU license, some claim that following it (which tends to mean following their personal interpretation of it rather than someone else's) is a moral imperative.
I'd suggest that it's pretty hard to claim some sort of universal moral or ethical obligation to follow IP laws generally. Now, I personally am as stringent as anyone you've ever met when it comes to IP law. I don't illegally download music, I don't pirate software, etc. Not doing those things is part of my moral system. But who am I to tell some Chinese peasant that it is immoral for him to xerox a book and sell it? Intellectual property as currently instantiated in the West is a very modern, Western-centric notion, and I guess I fail to see why the West's take on IP is somehow morally superior to much of the East, where IP has no moral, ethical, or practical legal force. There's an extreme difference there, but the same logic is applicable to this discussion. Who are you to tell someone that your view of the morality regarding something as specific as 'derivative works' is the right one? The whole idea of derivative works really has no bearing or history outside of legal systems to begin with. Certainly, no religion or major school of ethical thought has, as a tenet, anything regarding use of derivative works that I'm aware of. And you know, those who fall back to the ethical or moral argument when they feel that the legal argument may be shaky are engaging in a bit of fuzzy thinking, I feel. What's the basis for an ethical or moral judgement on intellectual property if not the law? I'm not really aware of any major school of ethical thought which recognizes the lack of intellectual property protection as being somehow 'wrong' or unethical. IP law exists for a practical purpose, not a moral or ethical one. --matt |

This shouldn't even be up for discussion. We all well know what the DIKU authors meant with their license. It has been stated time and time again by them. The fact that someone says it may be legally flawed, to most of us, is irrelevant.
Again, this is proven by the majority of DIKU mud owners honoring this "legally" flawed document. Call us idealists, call us idiots. I could care a less... Its simply the right thing to do. I feel sorry for those of you who think otherwise. Enjoy, Splork |

Quote:
One sociological basis for an ethical or moral judgement within a given society is whether or not a said action is considered socially acceptable. This is a basic concept of sociology. Example; In Ancient Greek society, it was socially acceptable for a Master of a Given Craft to follow certain social guidelines. Firstly, he must be Male(obviously to suggest this in modern American society would be considered unethical by many and not socially acceptable). Also, he must have undergone an apprenticeship before being considered a Master. This means that he must have moved in with a Craft Master, and that part of his apprenticeship meant that he was often forced to have a homosexual relationship with his Master. In modern American society, this also would be considered unethical(and actually, illegal). --- So the ethics of this issue could be re-stated this way; it would appear that the vast majority of vocal members of the online MUD social society have made the decision(whether actually backed up in court or not) that it is, indeed, not socially acceptable(within our community) to use even an altered DIKU codebase(like Medievia's, for example) as a method of capital gain. In this sense, the ethics of this topic seem to be related to sociology. Arguing that it should not be considered unethical merely means that you are trying to change the social norm; the same would be true, in America, if I were to argue that sexual equality in the workplace should not be the rule-of-thumb. However, I would find social resistance to this suggestion, as is the case in the MUDing community any-time someone such as Matt tries to insinuate(or even outright state) that Medievia and such MUDs have not acted unethically. |

I have followed this thread over the years and as many here have heard all kind of arguments pro and anti DIKU license. Since those who breach the license have not been sued and it appears to be that there is no interest whatsoever on doing so from part of the authors or the school that seems to own the code we cannot posibly come to a final answer to the question posed by the_logos.
That said, here are my thoughts on the subject. There are two different standards that are followed in here when discussing this or similar topics. One is the legal one, most frequently quoted by people who are in business and seem to be required to operate in the "what does the law say about it?" sphere. The main argument I have heard here is that the license is flawed, it does not forbid what the authors seemingly wanted to forbid (or claimed they wanted to after they were told it was poorly spelled out), a court would "probably not" rule in favor of the DIKU team or license holder because of this fact. It is my opinion that from a practical point of view this is true and will remain true until the license holder sues the first company or individual and wins. The other standard is the so-called moral standard, and it consists on reading and understanding the license according to the spirit of what was being written, not dwelling too long on exact definitions of particular words the authors chose to word their license document. The main view here, as I perceive it, is that the license forbids any form of personal gain from the game, which basically means, if you make money out of the game that would buy your weekend party nights you are violating the license. Furthermore, some people interpret it to mean that you should not hold comercial exchange or trade (or whatever the appropriate term is) with the code and virtual objects created with the code. This later part is a bit more confusing, since it is a particular way to interpret Quote:
This is the most voiced standard, mostly by admins or developers for non-comercial MUDs who work or have worked with DIKU derivative code, and who fully feel they have followed the license according to this interpretation. I believe one reason why there are more people with this point of view than with the so-called legal one is that there are more people who run their MUDs non-comercially-spirited (money comming in is used for upkeep, bandwidth, machine, etc.) than people who run MUDs as a business. I personally believe it is healthy to have comunity standards that are above the minimum legal standards, this means I agree that the spirit of the license should be followed up to the reasonable extent and that if someone wishes to be an active part of "this" comunity (ie. TMS forum members) it would be expected of them to adhere to this view or at least be reasonably close to adhering (notice the unfortune of having to "pick" words that can be interpreted in a zillion different ways, as "reasonably"). I think this is appropriate since, even if nobody has ever been found "guilty of DIKU license breaking" by a judge anywhere that I am aware of, the forum may police itself (through the site owner) to whatever standards the owner wishes to declare minimum. To summarise, there are two standards, a so-called legal one and a so-called moral one. Each of these standards is practically applied on different grounds, a court of law or everyday internet trade for the first, within a comunity sharing the moral standard for the second. It is my opinion that both views are quite correct, within their own ground and that the problem occurs when one tries to apply a standard outside of its ground of validity. Even if one tried to increase the reach of one of the standards to include the others ground, people would still reject the outcome; people will not stop considering Medievia is using DIKU derivative work without aknowledging it even if they won in a civil court after being sued by the DIKU team or school; people will not stop their comercial practices if the site owner and every single suscriber here declares it immoral to breach the DIKU license's spirit, this will not happen until they get sued and forced to stop by a court of law. |

I have a question for those of you with more time to do google searches or with more factual knowledge of cases like this:
Is there any precedent of a weak or seemingly flawed license being upheld in court based on the intent of the author rather than the actual exact wording? If yes, could you please provide us with some links where we could review the case? (if it is a public record) Other thing I wanted to ask, Is the case of banning certain interpretation of the DIKU license within this comunity that much different from a specific organized religion forbidding specific sexual practices that are otherwise socially accepted? (In my opinion the two cases are very similar, and this is what makes me think that IF the forum owner decided to enforce certain particular interpretation as condition for membership, he would be in his right to do so) Edited to fix a typo |

I'm fairly new to this discussion, I'd just like to know why Medivia do not wish to credit the Diku authors?
Is it because they claim their work is not of Diku origin? If so, has it been proven that their claim is wrong? Sorry, just trying to catch up with what everyone's talking about. I'm sure these questions have been answered somewhere else. |

"A software licence is not necessarily a contract. It can be, but that requires a couple of preconditions to be satisfied. One of those preconditions is the existence of consideration on both sides. Consideration is a legal concept that simply means a quid-pro-quo, or something of value given by each party in exchange for what the other party provides. In the case of open source software, there usually isn't anything provided by the licensee of the software (that is, the person who uses it) back to the licensor (usually, the person who wrote it). As a consequence of this lack of consideration there is no contract between the licensee and licensor." "Because the licensee hasn't given any consideration in exchange for the software, the licence can be revoked by the licensor at any time simply by giving notice to the licensee." (Wood v Leadbitter (1845) 13 M & W 838) |

Medievia's stance on the subject: The History of Medievia. I just want to state that Vryce wrote that page, not me. Any problems with it should go straight to him
As that link states, we do not deny our DIKU origin. Our claim is that our code is rewritten. Kavir reviewed our Medievia IV code in 1996 and made comparisons to DIKU and found DIKU code. However, since that time, 10 years ago now, we have totally rewritten our code. KaVir will respond to this thread soon with a lot of links I'm sure. He will also go on about 'once a derivative, always a derivative'. As for the license, it IS flawed and our lawyers have told us that it could never hold up in court. But, according to spoke, that is only the 'legal' take on the matter. We pretty much agree with matt's interpretation and he did such a wonderful job of summing it up, I don't need to add anything else. |

Regarding the whole "The Diku licence won't hold up in court" thing, this link provides some interesting points:
http://www.groklaw.net/articlebasic....31214210634851 It's in regard to the GPL, but the situation is very much the same, as both the GPL and diku licence are licences and not contracts. The following is quoted from Eben Moglen, the Free Software Foundation's attorney: "The GPL, however, is a true copyright license: a unilateral permission, in which no obligations are reciprocally required by the licensor. Copyright holders of computer programs are given, by the Copyright Act, exclusive right to copy, modify and redistribute their programs. The GPL, reduced to its essence, says: 'You may copy, modify and redistribute this software, whether modified or unmodified, freely. But if you redistribute it, in modified or unmodified form, your permission extends only to distribution under the terms of this license. If you violate the terms of this license, all permission is withdrawn.'" "Because the GPL does not require any promises in return from licensees, it does not need contract enforcement in order to work. A GPL licensor doesn't say in the event of trouble "But, judge, the licensee promised me he wouldn't do what he's doing now." The licensor plaintiff says 'Judge, the defendant is redistributing my copyrighted work without permission.' The defendant can then either agree that he has no permission, in which case he loses, or assert that his permission is the GPL, in which case he must show that he is obeying its terms. A defendant cannot simultaneously assert that the GPL is valid permission for his distribution and also assert that it is not a valid copyright license, which is why defendants do not 'challenge' the GPL." In summary: The Diku licence is the only thing giving permission to use DikuMUD. If the Diku licence were proven invalid, then you wouldn't have permission to use DikuMUD, and the mud would therefore be a copyright infingement. You can't use the usual contract law defences, because the lack of consideration means that the Diku licence is not a contract. |

Part of that grey area probably has to do with whether the code has been changed such that it is a new program. Hard core ehtusiasts often say to me, well, if you used it even as a framework, you violated the license. This is actually why I opened the thread I did down in the legal section of the forums. I have a problem with the intersection of copyright and patent law as it pertains to software. The copyright would seem to only apply to making copies of the source code, and the rub is that all code, ALL CODE, looks the same, or roughly so, in bits and pieces. So, while an author or song writer might point out a riff or a series of lyrics or a chapter that is obviously derived from their work, computer programs are pieced together largely with only a handful of basic comparisons and decision making algorithms. Remember your early computer science courses? Remember how everyone's programs looked EXACTLY the same except for variable names? As things get more advanced, you could probably make some arguments regarding overall form and organization of code that might hold up in copyright, but as has been pointed out, that is a complex task. The point is, anyone who has ever downloaded Diku or a derivitive now has been exposed to "their" code, and if they see anything at all in there useful to a computer program they might concieve of to make money, chances are that it is merely a variant of something that occurs in dozens if not hundreds of programs all over the earth. As far as the ethics go, I am afraid I have to come down squarely on the side of Diku enthusiasts. Whatever else happens, it is quite clear that the program Medievia uses developed stepwise and piecemeal from Diku, and I find that but lazy and ungrateful behavior on the part of whatever people involved themselves in that activity. Some years ago I wandered around pondering my options in making a mud of my own, and it was not so much that I planned to build a for profit mud as it was that I did not want to put all that effort into a mud that would be forbidden from being a profitable enterprise should I manage to make it good enough. Because of the license problems with LP, I decided against it. I searched and prodded for years now, and there are other options now, including Coffeemud, which I believe would have suited me at the time, but since then I have moved on and am pretty solidly a player and not an admin at heart as far as the hobby is concerned now. I will say this in support of those who, like Vryce, skirted the ethical issues and made their life's dream of making money doing something they really love come true. Given that neither the Diku nor LP teams cared enough about this hobby to stick around and make their own careers based on these games, it annoys me that they have nevertheless kept their fingers in the pie just enough to basically create the miasma of bad feelings that we see here now over this subject. I wish those guys would either do their business and start slinging lawsuits or get off the pot and let it go. It is a GAME! It's supposed to be for FUN! Well over 2 cents... |

The DIKU team has given a great resource to this community, and has helped this community arguably more than any other single, small team. They have allowed thousands and thousands of players free fun. The community, as a whole, has therefor embraced their wishes and vehemetly defended the DIKU license. It is for these reasons that it is deemed socially unacceptable or unethical, within our text-rpg community, to do what games like Medievia has done. It is simple. DIKU is a gift - they ask for next-to-nothing in return for its use. Those of us who appreciate this gift become very defensive when it is abused; hence why any suggestion that the DIKU license is unimportant is strongly resisted here. --- Beyond that, KaVir summed up my sentiments to the law-based arguments against the license; the DIKU license is the only thing that gives permission for its use. If the license is invalid, so is every MUD that uses it. |

It's not a favor they did me. Lars did me all the favors anyhow, and I to this day prefer the LP muds. I have read somewhere though that the first mud you ever play will have lasting effects on what you envision as the perfect mud, and I confess this is true of me. I played Ancient Anguish for years. I love that old game. I can still go back today and visit ol' Meaty and get a grin out of it. Or the librarian. lol... Anyhow, point being, it was not some sort of favor. Obviously they had a dream and the dream has turned into a nightmare. I honestly wish they would at this point come out publically and give all the people who ahve not broken their license the same opportunities as those they have given those who did by virtue of not choosing to try to enforce it. The endless arguing is a blot on the community. Someone has commented somewhere as to why the GPL has not benefited the mud community much. AIME has been rusting in Sourceforge for years. I kind of wish more people would give Coffeemud a try. I really think in the hands of a decent builder it could rock the socks off a few muds out there charging money. Quote:

For a person like that, the "gift" becomes a ball and chain and I for one can understand how one could easily be tempted to test the waters, and I will not demonize such a person. All I can do is confirm along with you that I think that was the weak, lazy way out. But given that the Diku team have not involved themselves in the ongoing evolution of the community, I have less and less sympathy for a wrong done to people who, frankly, do not appear to care one way or the other. Quote:
Quote:
Heck, I still am confused at how the fairly common practice of taking donations for a mud's operating expenses doesn't violate the license. And then, after all, one can then define "operating expenses" as so many different things, up to and including a coder/admin. One interpretation of the license would make it impossible to run a Diku on a rented server, because the server operatoirs are after all making money off the mud renting their space. So... rent a server, risk getting your mud shut down? Are the concerns of people like myself beginning to make any sense at all to you yet? Can you see how I am not trying to disrespect Diku, so much as just wishing this particularly ugly chapter in the history of the mud'ing hobby could come to some sort of final resolution? Another thing... copyright law is based on the idea that the copyrights are for the good of society, to help stimulate intellectual persuits, specifically giving those who want to make money off their work the ability to do so. If you want to give something away, why not just GIVE it? So the ethical outrage is really based on nothing at all that is easily based on the reality even of the law or why it was formulated in the first place. It is, if nothing else, a very poorly constructed and thought out and worded piece of work, that license. I am so very sympathetic to you and others who took this thing in the spirit I have to imagine it was intended, and formed the foundation of the hobby. I wonder how it might have been different if done another way. We will never know, I think, if it would have been better or worse had they simply released the code into the world and given it a peck on the cheek and told it to go forth and multiply, or what. I don't know. I just know this topic makes people angry and bitter and resentful and that is not a good thing. |

Two things.
Quote:
Secondly, and finally, DIKU is a gift - it is a free gift given to people who enjoy this RPG hobby as something other than a method of capital gain. If you enjoy the online text RPG hobby as a method of capital gain, you are simply asked by the team not to use their work for that capital gain. It is their wish, and really(beyond giving credit where credit is due), their only requirement for using their work. We are, as a community, lucky to have DIKU - if people seem to take a very strong stance on what the MUD-Community has deemed a social norm(respecting the DIKU license), it is because it is the least we can do in return for the use of the code. In summary, though it's been said time and time again; the community here, largely, expects that MUD-designers will not use DIKU codebase a) to make capital profit, and b) without crediting the DIKU team. If you do not abide by these social guidelines, it is very possible for you be under ethical scrutiny from the community. Infact, as with all social ethics, it should be expected; trying to change this, fundamentally, is no different than me lobbying in America against equal rights for women in the workplace - no matter what my reasoning or point of view is, I am likely to be met with strong social resistance. It's sociology, and human-kind has survived this way for many thousands of years. |

On another note, in regards to arguing and arguments themselves...

Historically, the break down of communication of ideas can be the cause of anything ranging from personal insults to religious wars and ethnic genocide. Once again, it is sociology. |

I personally think that the moral thing to do is to follow intent of the license. If you disagree with me, I respect your right to have a differing opinion, but I don't respect your opinion and I will judge you. Matt said in another thread we shouldn't judge people until they've been to court and the courts have decided if they've done something wrong. IMO this is great for the press and the law. But particular individuals who have nothing to do with either (such as Joe Blog down the street) are free (and should) to make a judgment for themselves. Quote:
I don't believe all IP laws should be followed. I don't believe all licenses should be followed in all instances. People are welcome to judge me on this if they wish. I respect their right to a differing opinion. Quote:
I believe that people blatantly breaking the DIKU license caused the creators to withdraw from the community. I feel continuing to break it is disrespectful and shows support for the original license breakers. This is my personal opinion, Medievia obviously has a differing opinion, I'll just say I disagree with them and would support them being banned from the message board (but with them here I'll of course treat them respectfully). Given the fact that no-one in the DIKU team will ever sue any license breakers, I actually feel discussing the legal aspects to be pointless. Quote:
Although given that you're a rather frequent poster (and do work on Medievia), care to share what your stance is? As for the argument that "Medievia V" has been re-coded so much that it's no longer DIKU (or was started from scratch) I'd want a (as unbiased as possible) coder to compare the two before I judge Medievia not guilty. Yeah I know "what about innocent until proven guilty?" Well they've made the claim before that they had changed the code so much it was no longer DIKU, I've read the comparisons of the code about whether or not it truly was changed enough and agree with the study that it wasn't change to a sufficient degree. Although I do stress the importance of an unbiased coder to do the check because I simply wouldn't trust someone like Kavir to check it. I could see him pointing to trivial aspects (where there are only so many good ways to achieve the desired result) and claiming it proof that it has DIKU code (no offence intended Kavir). There's also the "but if it was based on the DIKU then it's a derivative." Well that's a law-based argument. I have no opinion on the legal status of the code, because the DIKU team won't enforce the license via the courts, so I don't know why I should limit myself to the legal opinion. For me, if it was changed until all but the most trivial aspects remain, good enough for me. But I'm going to need proof. |

Because the legal aspects of this are pretty much irrelevant, imagine the MUD community as a frontier town with no police or search warrants. The old audit and everything that goes with it are the equivalent of everyone else in the town seeing a missing child enter your house and not come back out. No one in anarchy frontier town can force you to open your house and show them that the kid still isn't there, but until you do, it makes perfect sense for people to assume that she is. I suspect that you don't care if the MUD community likes you, and that's your choice, but neither should you feel the victim when they attack you over things that are within your control. |

In the case of Medievia, the DIKU driver is constantly being put in the spotlight, and all the other work that Medievia has done, is constantly ignored. I'm pretty sure that with the DIKU driver alone, Medievia wouldn't be able to get, nor keep, any paying customers. The reason people chose to play there, is because of all the content and auxiliary systems they themselves have added to the DIKU platform. If they were running yet-another-DIKU-clone with minimal customization, then I would agree that it's a blatant ripoff of the DIKU teams work, but that is not the case. I find it strange (and also utterly restrictive) that 5% of the sourcecode (26k lines versus over 500k lines), most (if not all) of which has been recoded since, would still affect the use of the whole codebase. I do not think this is what "derivative work" refers to, and I'll reiterate again, that several lawyers have been asked for their opinion (I consulted one who specializes in international IPR litigation) and their professional opinion has been that the DIKU license would not apply in the case of Medievia. (It would apply were I to sell copies of it, and likely if I were to make profit by running a stock DIKU). |

In addition to the license issue and other ethical issues, there is an even more clear-cut case of plagiarism with Medievia. They are a DIKU derviative, per US law (Copyright Act, at 17 U.S.C. §101):
A "derivative work'' is a work based upon one or more pre-existing works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation or any other form in which a work may be recast, transformed or adapted. A work consisting of editorial revisions, annotations, elaborations or other modifications which, as a whole, represent an original work of authorship, is a "derivative work''. In short, it doesn't matter what Medievia has done to modify the DIKU code. A movie based on Hamlet is a derivative work, even if I'm responsible for all the filming, sound, advertising, and I rewrote all the dialogue to conform to 21st-century grammar. A derivative work, by itself, does not constitute plagiarism. It is the fact that Medievia steadfastly refuses to credit the original authors for the work they are using to make a living. |

http://www.copyright.gov/circs/circ14.html COPYRIGHT PROTECTION IN A DERIVATIVE WORK The copyright in a derivative work covers only the additions, changes, or other new material appearing for the first time in the work. It does not extend to any preexisting material and does not imply a copyright in that material. Also of interest: Piecewise Reimplementation Many people have reimplemented computer programs by rewriting them to replace the source code with code of their own writing. There is no reason to believe that this would not be a copyright infringement, particularly if the reimplementer had access to the source code of the original program, even if none of the original source code remains. When the first segment of code is rewritten, the new code will be an infringing work if it is substantially similar to the original code, or may be an infringing derivative work if it is a reimplementation in a different programming language. That reimplemented first segment is combined with the remaining parts of the original program to form an intermediate version. Subsequent modifications produce another work. So when you have completed the piecewise reimplementation, you have a set of works, each of whose creation infringes the exclusive rights of the owner of the copyright of the original program. As an analogy, consider the translation of a novel to a different language, something that would clearly be a derivative work. It makes little difference that none of the original words remain, or that the translation was done a little at a time. The resulting translation is still an infringing derivative work. Even if you completely replace the program with new code, nonliteral elements also protected by the original program’s copyright are likely to remain and infringe – elements like the overall program structure or architecture and data structures that are not dictated by external or efficiency considerations. Although there is no case law on this point, it would seem that the only way to break the chain of infringing works is by some extraordinary act, such as a clean room implementation. |

I am afraid, KaVir, that you are the one that is mistakened. You keep quoting articles that do not directly deal with the enforcability of this license (and altering the source you are quoting - sometimes from US legislation, sometimes from Australian laws - as you see fit to back your claims). As a matter of fact, you weren't even quoting a section of the law, only a discussion around it.
Enter harsh reality - the implementation of laws is done on a case by case basis in a court of law, by a judge and through professional lawyers. That's how they make their money. It is not done by geeks on the Internet. If IPR and copyright laws really would be as simple and straightforward as just linking in a document, then there would not be any IPR lawsuits to begin with. But in reality, lots of other factors, including the extent of the infringement, limiting and aggravating factors, the wording of any license agreements etc *IS* taken into consideration. |

In the case of piecewise reimplementation, one very relevant issue is how significantly the code has changed. If all that remains from the original code is the function name (to assure compatibility) but the whole internal working of the function itself has changed, then I do not see how the author would not own the copyright for the change. Naturally this does not apply to minor modifications (change a few variable names etc). The author himself states why the piecewise reimplementation is problematic: Quote:

Just to recap: I have discussed the DIKU license with a lawyer. Medievia has discussed the DIKU license with a lawyer. Matt has discussed the DIKU license with a lawyer. You have: Quoted links that do not deal with the enforcability of the DIKU license, and refuse to accept that IPR litigation consists of much more than quoting a few sources on the Internet or even a clause from the law. IPR litigation is always decided on a case-by-case basis, based on evidence presented, mitigating factors and financial harm caused. In addition, you want to claim that all of us are just liars. Good game, snap out of your dreamworld. |
