Might be nice, but I think it is a bad idea (details below.) Doing it in haste is a very bad idea. In a quick look at the database of license clauses and examples at: http://www.mibsoftware.com/librock/lidesc/tags.htm I think existing OSI-approved licenses could have clauses which conflict with the proposed new clause. First many, many licenses restrict modification, or at least place conditions on it ("Prominent change notices, preserve license and copyright notices, patches only, derivatives must be under this same license i.e. copyleft, etc.) It is important to note that although some licenses place those conditions on the publication of modified versions. (see license examples for the librock_DM_* group of tags) other licenses place the condition on just making the modification! (I don't know if it would hold up in court under a fair use test, but I think there are licenses which can be read that way, like the W3C clause 3.) But you might want to look at the exact wording of all the example licenses for each librock LIDESC tag starting 'librock_DM_' and the librock_DERIV_DIFFLIC_0 tag, which is the "copyleft" tag. http://mibsoftware.com/librock/lidesc/exlibrock_DERIV_DIFFLIC_0.htm ------------------ librock_RUNNOTE_1C This tag means "A notice must be included at run time in some cases." See http://www.mibsoftware.com/librock/lidesc/exlibrock_R_PATGRANT.htm for explanation, with example licenses and clauses, including the GPL (clause 2c which applies when you modify and distribute.) ------------------ librock_R_PATGRANT This tag means "Redistribution of the original work must include a royalty-free grant of patent license." But the clauses themselves often have reciprocal clauses which could amount to usage restrictions. See http://www.mibsoftware.com/librock/lidesc/exlibrock_R_PATGRANT.htm for explanation, with example licenses and clauses, including: IBM Public License Version 1.0 (clause 2.b) It is much more common to see licenses which get the librock_DM_PATGRANT classifier: "Redistribution of modifications must include a royalty-free grant of patent license", Many more examples that need a careful reading to determine if they confluct with proposed OSD clause 0. See http://mibsoftware.com/librock/lidesc/exlibrock_DM_PATGRANT.htm (Examples include APSL 1.2, IBMPL 1.0, Jabber, Mozilla) ----------------- librock_RUNNOTE_1 "A notice must be included at run time always." See http://www.mibsoftware.com/librock/lidesc/exlibrock_RUNNOTE_1.htm for explanation and examples, including the W3C clause 1, which requires that users be able to read the notice. ------------------------- librock_PUBMSRC_1C_DEPLOY. See http://mibsoftware.com/librock/lidesc/exlibrock_PUBMSRC_1C_DEPLOY.htm for explanation and examples, including the APSL version 1.2, clauses 2.2c and d. --------------------- Some licenses always seem to be borderline cases, and the Librock license database could be more complete. For example, the QPL always seems to be a border case. It has a use restriction in clause 5: 5. You may use the original or modified versions of the Software to compile, link and run application programs legally developed by you or by others. I am not really sure what that means. I suppose the only exclusions it makes are the "illegally developed" software, such as the software the DMCA outlaws. --------------------- Then there are some licenses which have OSD conflicts because of some clauses, but have other clauses not in conflict with the existing OSD, that would be in conflict with the proposed clause 0. (For example, the Sun Community Source License version 2.3 clause 3.b which requires "error corrections [go back to Sun ....] prior to internal deployment use.") We don't care about those licenses, but do we care about allowing similar license clauses if they don't already conflict?
