"Free" OXP list anybody?

Post by Danfun128 »

Hello. Can somebody make a list of all the OXP's that are "free"? I keep finding too many OXP's that are nonfree, and there is no easy way to manage them.

Free licenses:
gpl
cc-by
cc-by-sa
cc0

Non-free licenses:
cc-by-nc
cc-by-nc-sa
cc-by-nd
cc-by-nc-nd

This is, of course, assuming the main game data is still dual licensed gpl2/cc-by-nc-sa. And of course, there are probably other licenses I'm forgetting...

Danfun128 is referring to "free" in the sense of "freedom to do whatever you please with the material".. not in the sense of "free beer"..

To quote Wkipedia on the subject:
Free content, or free information, is any kind of functional work, artwork, or other creative content that meets the definition of a free cultural work. A free cultural work is one which has no significant legal restriction on people's freedom:

* to use the content and benefit from using it,
* to study the content and apply what is learned,
* to make and distribute copies of the content,
* to change and improve the content and distribute these derivative works.

Although different definitions are used, free content is legally similar if not identical to open content. An analogy is the use of the rival terms free software and open source which describe ideological differences rather than legal ones.
In the case of this discussion, points 3 and 4 in the bulleted list are the most important ones.


G'day, Danfun128, and welcome aboard! 8)

Licensing is one of those thorny issues which we are still, to some extent, getting to grips with when it comes to OXPs.. witness the recent discussion over "dead-man" clauses, for instance.. To my knowledge, nobody has yet compiled such a list, as the uses for same would appear to be rather limited. Generally speaking, licensing is of little interest except for OXP authors who may wish to borrow from or adapt the work of others. The only other reasons that come to mind for creating such a list are for somebody seeking to re-distribute OXPs themselves, or for those individuals obsessed with having zero non-free code or other material on their computers..

Since you seem to have been examining OXPs from a licensing perspective already, perhaps you yourself are well positioned to contribute such a list.

Hmm.. why do you feel there are "too many" that are nonfree? And could you clarify what you mean by "manage them", please?

Correct. To be more specific, the game code is GPL2.. the game resources – models, textures, sounds, images - are dual-licensed.. (GPL2/CC-by-nc-sa-3). See here for further details.

Because there is no central control over, or repository for OXPs, the only way to compile such a list would be to download each OXP and check its licence so they can be listed.
Anybody is free to do this if they want to...

As for 'what is free?', well as has been said, they are all free as in beer, and most have a very liberal licence (mostly CC-by-nc-sa 3) which means they are free to use and/or adapt but with a couple of reasonable restrictions, namely that the original author requires a mention (fair enough I think), they cannot be used for any commercial purpose (also fair enough - we authors put in many hours producing our work which we then freely and happily give to the community, and most of us would object strongly to a third party exploiting them for personal gain), and that derivatives should carry the same licence (thus perpetuating the 'freedom').

Well, for example, just for my own use I have, during the last year, been compiling a new version of Oolite Extended - for those who might not know, that would be a version of Oolite with nearly all available oxps, obviously except HUD and cheat/fun oxps, preinstalled - one that can be downloaded and played stable, for people who want everything in one go, but don't have the 10 workdays or so they would need to download and put it all together and make it work themselves :wink:

I did not do this by merging this time - as this was quite the dead-end update-wise - but simply by getting a gigantic 650-oxps folder to play together unmodified. With a few frame-oxps included.

So, I can imagine that quite some players might like to have this, and it might not produce problems with incompatibilities as a merger as the old version did, and could be updated by hand with original oxp updates by anyone who used it - but for any sort of release to the community, the licensing issue is in the way here too.

As I have no intention of upsetting people who have greatly contributed to this game and its oxps, this means that this option, for example, won't happen, as I am not wading into some gigantic debate with 300+ people about lots of details again.

So much for reasons that might come to mind.

Well, that discounts nearly all the really popular ones! :P

I'm pretty sure that your particular situation was covered by my "somebody seeking to re-distribute OXPs themselves" comment.. :wink:

Entirely true!

I'm simply a bit frustrated that there seems to be no way to do a OE V2.0 without stepping on toes heavily, and I would only do it in case of consensus nowadays :(

Long-term such information will be extractable for many expansions from the OXZ index, since "license" is one of the optional keys in the manifest.plist file. But that's not going to happen until some time after we have a released version which supports the OXZ format, of course.

In the short term... my impression would be that the majority of OXPs are under an CC-*-NC-* license or something more restrictive. As a starting point for the list:
- Dr Nil's are under a very unrestrictive license (though not a particularly formal one). However, you might find that some have been worked on by other people since and the combined work is under a more restrictive license.
- mine tend to be CC-BY-SA 3 (and the only one not redistributable under a DFSG-compatible license is Energy Bomb, which was based on an earlier NC work)
- there are a few other "do what you want with it" license grants scattered around in forum posts for some older OXPs, but I can't remember who and where.
