SPARQL2Git: Transparent SPARQL and Linked Data API Curation via Git

Abstract

In this demo, we show how an effective and application agnostic way of curating SPARQL queries can be achieved by leveraging Git-based architectures. Often, SPARQL queries are hard-coded into Linked Data consuming applications. This tight coupling poses issues in code maintainability, since these queries are prone to change to adapt to new situations; and query reuse, since queries that might be useful in other applications remain inaccessible. In order to enable decoupling, version control, availability and accessibility of SPARQL queries, we propose SPARQL2Git, an interface for editing, curating and storing SPARQL queries that uses cloud based Git repositories (such as GitHub) as a backend. We describe the query management capabilities of SPARQL2Git, its convenience for SPARQL users that lack Git knowledge, and its combination with grlc to easily generate Linked Data APIs.
