Linked Data Engine

by Daniel Alexander Smith on January 23rd, 2010

Further to the demo of the Data Picker, we have developed a series of inter-linked services that are collectively referred to as the “Linked Data Engine.” The motivation for this development is to enable our existing architecture of picking data from a SPARQL endpoint to be extended to work with arbitrary Linked Data on the web. This means that users that do not have the capability to create a SPARQL end point can still create a faceted browser over data.

The Linked Data Engine is currently partitioned into the Data Picker (as above), and a Data Processing service that handles ingest of RDF into a triplestore.

The interaction of these services is described in the diagrams below:

The Data Processor service is now integrated into the Data Picker, so that a URI can be used as the basis for creating an mSpace, and this has been working well in initial tests.

The formal information page for the linked data engine can be found at Daniel’s homepage, and goes into detail about the APIs for each service, and will eventually link to the source code of the services too.

We’ll post some more information up here as we finalise testing.

  1. This is a message to the admin. Your website is missing out on at least 300 visitors per day. I have found a company which offers to dramatically increase your traffic to your site: They offer 1,000 free visitors during their free trial period and I managed to get over 30,000 visitors per month using their services, you could also get lot more targeted visitors than you have now. Hope this helps :) Take care.
