Abstract: AllegroGraph is a fully ACID and highly scalable RDF triplestore that can be programmed with compiled, server side JavaScript. This allows programmers to easily manipulate individual triples and create their own intelligent graph or reasoning algorithms. However, one wish that has been expressed by many programmers is to work on the level of objects instead of individual triples, where an object would be defined as all the triples with the same subject. So we created a MongoDB interface where programmers can add, delete and modify JSON objects directly into MongoDB like sub-stores. This gives us the best of both worlds. We get the beautiful simplicity of the MongoDB interface for working with objects and we get the all the properties of an advanced triple-store, in this case joins through SPARQL queries, automatic indexing of all attributes/values, ACID properties all packaged to deliver a simple entry into the world of the Semantic Web.
