The incubating Apache PDFBox includes AFM font metrics files for the core PDF fonts. The files are available from http://www.adobe.com/devnet/font/#pcfi and come with a file containing the following license.
This file and the 14 PostScript(R) AFM files it accompanies may be used,
copied, and distributed for any purpose and without charge, with or without
modification, provided that all copyright notices are retained; that the
AFM files are not distributed without this file; that all modifications
to this file or any of the AFM files are prominently noted in the modified
file(s); and that this paragraph is not modified. Adobe Systems has no
responsibility or obligation to support the use of the AFM files.
I believe this is consistent with Apache policies and that we can redistribute these files. Am I right?
