On the Fly SPARQL Execution for Structured Non-RDF Web APIs

Abstract

The concept of the Semantic Web, built around the idea of semantically described Linked Data and the data model of the Resource Description Framework (RDF), has become a prominent idea of seamless access to, and integration of, data. The number of tools to translate from non-RDF to RDF-representation of data has since then been ever increasing. However, to this day, numerous Web APIs do offer time critical data only in non-RDF-formats. Examples for this are traffic and public transport live data. Due to its nature, an offline data dump, as mostly generated by RDF lifting translation tools, is not practical, as it becomes inconsistent with the original data quickly. In this paper, we for this present an approach, that, published as a microservice, allows to send semantic queries against the legacy Web interfaces directly, and return the result in RDF. The service API follows the SPARQL 1.1 Query API specification, and also supports federated queries over distributed endpoints, allowing an easy and accessible way for semantically enriched data integration over legacy endpoints.
