“…Active-RDF has been an early proposal for handling Semantic Web data -however, without exploiting ontological information in the programming environment and not exploiting typing environment [8]. Modern approaches reuse ontological knowledge for helping the developer and the stability of the resulting programm [7].…”

When developing user interfaces for interacting with data and content one typically assumes that one knows the type of data and one knows how to interact with such type of data. The core idea of the Semantic Web is that data is self-describing, which implies from a data consumer's point of view that its semantics is not designed and described according to its use, but according to possibly orthogonal concerns of a data publisher and that its usage semantics emerges over time. The ensued flexibility is one of the greatest assets of the Semantic Web, but it also severely handicaps intelligent interaction with its data.

“…Approaches that create mappings between ontologies and, for example, the object model of object oriented languages, can offer at least some form of verification. Existing mapping frameworks include ActiveRDF [38], Alibaba [52], Owl2Java [27], Jastor [51], RDFReactor [45], OntologyBeanGenerator [1], Àgogo [41] and LITEQ [31]. However, mapping approaches come with their own set of limitations.…”

“…Type providers [12,31,50] follow a goal similar to ScaSpa-bridging the gap between programming language and information sources. Compared to more naive mapping approaches, type providers are not directly limited by the size of the data source (types can usually be created lazily, when needed) and do not necessarily cause a runtime overhead, since provided types can be erased.…”

Graph-based data models allow for flexible data representation. In particular, semantic data based on RDF and OWL fuels use cases ranging from general knowledge graphs to domain specific knowledge in various technological or scientific domains. The flexibility of such approaches, however, makes programming with semantic data tedious and error-prone. In particular the logics-based data descriptions employed by OWL are problematic for existing error-detecting techniques, such as type systems. In this paper, we present DOTSpa, an advanced integration of semantic data into programming. We embed description logics, the logical foundations of OWL, into the type checking process of a statically typed programming language and provide typed data access through an embedding of the query language SPARQL. In addition, we demonstrate a concrete implementation of the approach, by extending the Scala programming language. We qualitatively compare programs using our approach to equivalent programs using a state-of-the-art library, in terms of how both frameworks aid users in the handling of typical failure scenarios.

Abstract. Semantic data fuels many different applications, but is still lacking proper integration into programming languages. Untyped access is error-prone. Mapping approaches cannot fully capture the conceptualization of semantic data. In this paper, we present λDL, a typed λ-calculus with constructs for operating on semantic data. This is achieved by the integration of description logics into the λ-calculus for both typing and data access or querying. The language is centered around several key design principles, in particular: (1) the usage of semantic conceptualizations as types, (2) subtype inference for these types, and (3) type-checked query access to the data by both ensuring the satisfiability of queries as well as typing query results precisely. The paper motivates the use of a designated type system for semantic data and it provides the theoretic foundation for the integration of description logics as well as the core formal definition of λDL including a proof of type safety.
