Property-based typing with LITEQ ( PREPRINT ) Programming access to weakly-typed RDF data

Coding against the semantic web can be quite difficult as the basic concepts of RDF data and programming languages differ greatly. Existing mappings from RDF to programming languages are mostly schema-centric. However, this can be problematic as many data sources lack schematic information. To alleviate this problem, we present a data centric approach that focuses on the properties of the instance data found in RDF and that lets a developer create types in his programming language by specifying properties that need to be present. This resembles a type definition rooted in description logics. We show how such a type definition can look like and demonstrate how a program using such type definitions can can be written.
