DescriptionA native JSON - document store inspired by Lotus Notes, scalable from globally distributed server-clusters down to mobile phones.All data is stored inside objects which are linked by so-called link attributes. Objects consist of classes which can be extended and de-extended at runtime. Graphs can be defined with a struct.An open source graph database built for real-time streaming and compatible with Neo4jJavaScript DBMS with an API inspired by CouchDBPlatform for big data analytics on multistructured data sources and types
