Today we are unveiling Osiris. Osiris is an Open Source server for Indoor Maps based on OSM. It is perfect for Smart City projects and it can be loaded with Simple Indoor Tagging maps. We are using it on several R&D projects that we are participating and in one of our corporate buildings.
This software uses MongDB as a geospatial DB and a web services layer programmed in Java accessible through REST calls. We provide the source, documentation and even an android sample app.

We are open to your opinions and contributions.
