| Abstract | There are hundreds of SPARQL endpoints on the Web, but finding an endpoint relevant to a client's needs is difficult: each endpoint acts like a black box, often without a description of its content. Herein we briefly describe Sportal: a system that collects meta-data about the content of endpoints and collects them into a central catalogue over which clients can search. Sportal sends queries to individual endpoints offline to learn about their content, generating a best-effort VoID description for each endpoint. These descriptions can then be searched and queried over by clients in the Sportal user interface, for example, to find endpoints that contain instances of a given class, or triples with a given predicate, or more complex requests such as endpoints with at least 1,000 images of people. Herein we give a brief overview of Sportal, its design and functionality, and the features that shall be demoed at the conference. |
