In answer to the first question: no, I am not aware of any mandate placed on us in this regard. We did make explicit commitments of our own in our proposal about licensing, and we're now bound to abide by those.
Here is a list of the software and content that we will use, modify or produce, indicating the license that now governs (or will govern) each:
- The Duke Databank of Documentary Papyri (cc-by)
- The Inscriptions of Aphrodisias 2007 (cc-by)
- The Inscriptions of Roman Cyrenaica (cc-by)
- The Inscriptions of Roman Tripolitania (cc-by)
- The Papyrological Navigator (GPL)
- Pleiades (code GPL; content cc-by-sa)
- EpiDoc toolset (GPL)
- Atom web feeds serializing OAI/ORE resource maps (following license of parent resource)
