Is it possible to model hypergraphs over arangodb? We are interested in building a wordnet like database for tamil language.

Please take a look at this http://hypergraphdb.org/docs/apps/wordnet/

Is it possible to model such a structure over arangodb(with or without some wranglings)?

Thanks,
Vanangamudi

Yes you can add an arbtritary number of edges between vertices in ArangoDB.

Is it also  possible to add relationships between edges - edges to edges?

Yes it is possible to save those.
However than you need to keep that in mind during quering.

The query executor will always treat a target of an edge like a vertex, it will not "magically" continue walking alongside this edge.
So if that is a requirement you need to handle those cases within the query yourself (e.g. by reading `_from` resp. `_to` from the edge pointed to and continue the traversal there.
