New “Time Machine” feature and Time Properties Charts – Now Available in v7.0
The free-form nature of triple-stores offers a lot of flexibility for constructing databases, but that freedom can also make it less obvious how to find arbitrary data for retrieval, error-checking, or general browsing. Gruff is a freely downloadable graphical triple-store browser that makes data retrieval more pleasant and powerful with a variety of tools for laying out cyclical graphs, displaying tables of properties, managing queries, and building queries as visual diagrams.
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.
Gruff is a free product from Franz.
