Gremlin-ATL: Scalable Model Transformations over NoSQL Databases

Industrial use of Model Driven Engineering techniques has emphasized the need for efficiently store, access, and

NeoEMF: a multi NoSQL Persistence Framework for Very Large Models

NeoEMF is a multi-database model persistence solution, that is able to store models in several kind of NoSQL datastores, including graph, map and column databases

Big Data and modeling: Are they mutually compatible?

Ten thngs to keep in mind when mixing modeling and big data. Modeling is as important as ever when dealing with big data but it must be adapted

UMLtoGraphDB: Mapping UML to NoSQL Graph Databases

Few solutions target UML to NoSQL code-generation and even less consider OCL constraints. We present a UML/OCL transformation to Blueprints, an abstraction layer on top of a variety of graph databases

PrefetchML: A DSL to define Prefetching and Caching rules on EMF models

How to speed up the access and queries on large models thanks to our language (and execution environment) to define prefetching/caching plans for specific modeling scenarios

JSONDiscoverer: Visualizing the schema lurking behind JSON documents

New version of our tool able to infer the shared schema among a set of schemaless JSON Documents

Mogwaï: Querying large models via an OCL to NoSQL / GraphDB transformation

Mogwaï is framework to store large models in a GraphDB NoSQL backend (thanks to NeoEMF) and efficiently query those models by means of a OCL to Gremlin (a query language for some NoSQL databases) transformation.
