Versioned Triple Pattern Fragments: A Low-cost Linked Data Interface Feature for Web Archives
In Proceedings of the 3rd Workshop on Managing the Evolution and Preservation of the Data Web (2017)
Linked Datasets typically evolve over time because triples can be removed from or added to datasets, which results in different dataset versions. While most attention is typically given to the latest dataset version, a lot of useful information is still present in previous versions and its historical evolution. In order to make this historical information queryable at Web scale, a low-cost interface is required that provides access to different dataset versions. In this paper, we add a versioning feature to the existing Triple Pattern Fragments interface for queries at, between and for versions, with an accompanying vocabulary for describing the results, metadata and hypermedia controls. This interface feature is an important step into the direction of making versioned datasets queryable on the Web, with a low publication cost and effort.
