Live Storage and Querying of Versioned Datasets on the Web

In Proceedings of the 14th Extended Semantic Web Conference: Posters and Demos (2017)

Linked Datasets often evolve over time for a variety of reasons. While typical scenarios rely on the latest version only, useful knowledge may still be contained within or between older versions, such as the historical information of biomedical patient data. In order to make this historical information cost- efficiently available on the Web, a low-cost interface is required for providing access to versioned datasets. For our demonstration, we set up a live Triple Pattern Fragments interface for a versioned dataset with queryable access. We explain different version query types of this interface, and how it communicates with a storage solution that can handle these queries efficiently.
