This demonstration presents the core feature of NeoEMF. First we present the supported backends and we import into each one an existing XMI model.

Then, we present the NeoEMF editor, a lightweight model editor that allows to navigate and update large models stored in NeoEMF.

EMF integration is briefly introduced by computing a Java-based query on top of each NeoEMF resource, and the execution of an OCL query is shown to demonstrate the integration of the framework in the modeling ecosystem.

Finally, we present two additional frameworks that take advantage of specific NeoEMF databases: Mogwaï, an efficient query framework which translates OCL queries into graph database traversals, and ATL-MR, a distributed ATL engine on top of Map-Reduce.
