Sig.ma demonstrate a quite pragmatic component developed in the LOD2 Stack, Sig.ma EE will be distributed in the first release of the integrated version of the stack that will be released in late 2011 by the LOD2 project!
The original Sig.ma
The http://sig.ma service was created as a demonstration of live, on the fly Web of Data mashup. Provide a query and Sig.ma will demonstrate how the Web of Data is likely to contain surprising structured information about it (pages that embed RDF, RDFa, Microdata, Microformats)
By using the Sindice search engine Sig.ma allows a person to get a (live) view of what’s on the “Web of Data” about a given topic. For more information see the respective blog post. For academic use please cite Sig.ma as in [1].

Introducing Sig.ma Enterprise Edition (EE)
The Sig.ma team is happy to introduce Sig.ma EE , a standalone, deployable, customisable version of Sig.ma.
Sig.ma EE is deployed as a web application and will perform on the fly data integration from both local data source and remote services (including Sindice.com); just like Sig.ma but mixing your chosen public and private sources.
Sig.ma EE currently supports the following data providers:
- SPARQL endpoints (Virtuoso, 4store )
- YBoss + the Web (Uses YBoss to search then Any23 to get the data)
- Sindice (with optionally the ability to use Sindice Cache API for fast parallel data collection)
It is very easy to customise visually and to implement new custom data providers (e.g. for your relational or CMS data) by following documentation provided with Sig.ma EE.
Want to give it a quick try? Sig.ma EE now also powers the service on the http://sig.ma homepage so you can add a custom datasource (e.g. your publicly available SPARQL endpoint) directly from the “Options” menu you get after you search for something. It is very easy to implement new custom data source (e.g. for your relational or web CMS data) by implementing interfaces following the examples.
Sig.ma EE is open source and available for download. The standard license under which Sig.ma EE is distributed is the GNU Affero General Public License, version 3. Sig.ma EE is also available under a commercial licence. Please contact us to discuss further.
