I think we once had the idea to keep a history of all the authors working on a certain ggb file in the XML file. This would be a nice way to support the "Attribution" in CC-BY-SA on GeoGebraTube as well.
Is anyone already working on this or someone interested to have a play with it?
As you may have know we already have some kind of history in GeoGebraTube: If you see a material you like you can create a copy of it to translate or change the construction, a connection to the original material is automatically created. That way we can automatically attribute the original author.
The problem I see with using the ID for attribution on GeoGebraTube is that in the end we will have materials uploaded by users A, B and C, and we know that all three are based upon some original file X. But we don't know how the materials are really interconnected: Whether it's A -> B -> C or A -> B, A -> C or X->A, X->B->C.
We cannot just guess who's to be attributed, so if we would want to use the ID for attribution we could either just say "material A is somehow connected to B and C", which is no attribution at all, or we could ask the user. But both options are not really satisfying, that's why I prefer to not intervene there.

there is just one ID. We could distinguish in theory by generating a new ID everytime the XML data of the file is accessed (ie potentially stored somewhere) and keep all previous IDs to have a complete history -- but I understood the original request to find some useful applications for what we already have, not to build something new. :-)

as Mike enlightened me, we already have a "fileID" stored in a ggb file that is kept across load/save. So, together with the authoring history of GeoGebraTube this should be fine, no need for an additional author history in ggb files right now.
