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

[Kristian Sons]

Hi,

sorry for the delay. I now published the EMF data structure for XML3D on 
GitHub:
https://github.com/xml3d/xml3d.ecore

Besides a master branch, there is a branch called "generated" that 
(surprisingly) contains the files generated from the model.

Don't hesitate to contact me if you run into issues.

Best,
   Kristian
