POD-QUERY: Schema Mapping and Query Rewriting for Solid Pods.
POD-QUERY: Schema Mapping and Query Rewriting for Solid Pods.
We envisage a decentralized Web architecture in which access to data in Solid pods is mediated by Web agents. Leveraging methods from information integration and data exchange, Web agents can give clients access to views defined by schema mappings. Queries formulated by clients over the view are rewritten by the agent to queries that work correctly over the base data. We demonstrate POD-QUERY, our prototype implementation of such an architecture, where schema alignment is specified by RDF-to-RDF mappings written in RML, and SPARQL queries are rewritten based on these mappings. We demonstrate our system in a personal health scenario.
