[Fiware-miwi] Java lib for writing XML3D content?

[Philipp Slusallek]

Hi,

I have talked to Prof. Zipf (GIS, Heidelberg on Monday). They have a
full server (in Java!) for the OGC-Web3D-Service on top of OpenStreetMap
and he is very interested in a broad support for such services.

I have asked him if he would be interested in contributing his server
code as open source. He was at least interested but wanted to discuss
this internall. I expect to hear from him  soon.

This sounds really interesting. How this relate to the XML3D-Repo stuff
that we have been doing
(https://graphics.cg.uni-saarland.de/2013/xml3drepo/)?

Best,
