Overview of an RDF triple store

[dbooth-boston]

We need tooling for understanding the contents of a triple store or RDF dataset. What kinds of relationships are present? What do they mean? What are the namespaces used, and their purposes? In a RDBMS this is fairly simple given an ER diagram. We need the ability to visually zoom in or out, like with google maps.

We are using HCLS to describe our triplestores. It can be browsed on GraphDB

Or we provide 2 SPARQL queries to retrieve those informations in convenient format:

• Explore the graphs
• Explore relations between classes

Here are the SPARQL queries we are executing to compute HCLS statistics for a graph.

We consider working on a service to visualize the content of a triplestore based on precomputed HCLS statistics (part of the data2services ecosystem). We would like to offer the possibility to deploy a user-friendly service allowing to understand the content of a triplestore, visualize relationships between entities, zoom in/out. Provide the user a tool to easily jump in a triplestore, find what he is looking for and understand the knowledge representation.

Anyone have pointers about work on such topics?
