Use gruff to display visual graphs of subsets of a store's resources and their links. By selecting particular resources and predicates, you can build a visual graph that displays a variety of the relationships in a triple-store. Gruff can also display tables of all properties of selected resources or generate tables with SPARQL queries, and resources in the tables can be added to the visual graph.

Zanran helps you to find 'semi-structured' data on the web. This is the numerical data that people have presented as graphs and tables and charts. For example, the data could be a graph in a PDF report, or a table in an Excel spreadsheet, or a barchart shown as an image in an HTML page. This huge amount of information can be difficult to find using conventional search engines, which are focused primarily on finding text rather than graphs, tables and bar charts. Put more simply: Zanran is Google for data.

Freebase contains at this time of writing more than 10 million topics, more than 3000 types, and more than 30,000 properties. This is not a small database by any measure. If you were to think of it in terms of relational databases, it is probably the database with the most number of relational tables (3000+ types), and the most number of table columns (30,000+ properties).

A semantic wiki is a wiki that stores some portion of its data in a way that can be queried elsewhere. Typical uses of such data include querying it within the wiki (sometimes using standard query languages like SPARQL), aggregating it in displays like tables, maps and calendars; exporting it via formats like RDF, OWL or CSV; and reasoning with it, to calculate new facts from the given facts. Semantic wikis do not necessarily need to include standards or technologies considered part of the Semantic Web, although they usually do, to some extent.

LiDRC Lab Linked Data Research Centre (LiDRC) Laboratory The LiDRC Lab is a collection of tools and demos we are working on in the Linked Data Research Centre, DERI at NUI Galway. Experimental Tools & Services In the table below you'll find tools and services we are experimenting with. They are likely not stable and are subject to (rapid) change.

wiki contains the infobox-to-ontology and the table-to-ontology mappings which are used by the DBpedia extraction framework as well as the ontology definition itself. The framework collects the templates defined in this Wiki and extracts the Wikipedia content according to them (As of March 2010, only the dump extraction uses the mappings. DBpedia Live is going to follow shortly).

The Tabulator project is a generic data browser and editor. Using outline and table modes, it provides a way to browse RDF data on the web. RDF is the standard for inter-application data exchange.

The ConceptWiki is a universal open access repository of editable concepts. ConceptWiki will evolve from the wiki that is found here now. There will be some rearrangement of the interface and when complete, the ConceptWiki will feature, for each specific concept, a Also Known As table containing identifiers (from various databases) and the associated terminological information.

DERI's Linked Data Research Centre (LiDRC) is organised into research themes addressing certain aspects of Linked Data publishing and consuming. You can find the current research themes in the table below or have a look at the LiDRC Lab, a collection of tools and services we are working on.

"The Semantic MediaWiki (SMW) extension allows for managing structured data in your wiki and for querying that data to create dynamic representations: tables, timelines, maps, lists, etc."
