Rainer Schöpf of the CTAN team pointed out that there is a new version of the LaTeX Project Public License, version 1.3, http://www.latex-project.org/lppl/lppl-1-3.html. He stated that this version is DSFG compliant, although I could not find this statement on the web site.
The clauses relevant to FOP's ability to distribute hyphenation patterns derived from files under the LPPL seem to be: 6. If you are not the Current Maintainer of the Work, you may distribute a Derived Work provided the following conditions are met for every component of the Work unless that component clearly states in the copyright notice that it is exempt from that condition. Only the Current Maintainer is allowed to add such statements of exemption to a component of the Work. a. If a component of this Derived Work can be a direct replacement for a component of the Work when that component is used with the Base Interpreter, then, wherever this component of the Work identifies itself to the user when used interactively with that Base Interpreter, the replacement component of this Derived Work clearly and unambiguously identifies itself as a modified version of this component to the user when used interactively with that Base Interpreter. b. Every component of the Derived Work contains prominent notices detailing the nature of the changes to that component, or a prominent reference to another file that is distributed as part of the Derived Work and that contains a complete and accurate log of the changes. c. No information in the Derived Work implies that any persons, including (but not limited to) the authors of the original version of the Work, provide any support, including (but not limited to) the reporting and handling of errors, to recipients of the Derived Work unless those persons have stated explicitly that they do provide such support for the Derived Work. d. You distribute at least one of the following with the Derived Work: 1. A complete, unmodified copy of the Work; if your distribution of a modified component is made by offering access to copy the modified component from a designated place, then offering equivalent access to copy the Work from the same or some similar place meets this condition, even though third parties are not compelled to copy the Work along with the modified component; 2. Information that is sufficient to obtain a complete, unmodified copy of the Work. 7. If you are not the Current Maintainer of the Work, you may distribute a Compiled Work generated from a Derived Work, as long as the Derived Work is distributed to all recipients of the Compiled Work, and as long as the conditions of Clause 6, above, are met with regard to the Derived Work. 10. a. A Derived Work may be distributed under a different license provided that license itself honors the conditions listed in Clause 6 above, in regard to the Work, though it does not have to honor the rest of the conditions in this license. Clause 6.d.2 is a bit tricky I guess. The rest seems OK. Note that the URL of the LPPL has been changed to http://www.latex-project.org/lppl/ (listed on http://nagoya.apache.org/wiki/apachewiki.cgi?FOPAudits/March2003) Regards, Simon -- Simon Pepping home page: http://www.leverkruid.nl
