Challenges & Opportunities of RSP-QL Implementations
The RSP-QL model explains and unifies RDF Stream Processing (RSP) approaches into a more general semantics. It was successfully applied to model C-SPARQL, CQELS-QL and SPARQLstream taking into account the operational semantics of the existing implementations. In this paper, we present Yasper 1.0, an RSP engine that implements RSP-QL semantics. Moreover, we present the challenges we found during...
متن کاملYasper 1.0: Towards an RSP-QL Engine
In the Stream Reasoning (SR) research, working prototypes often came along with foundational investigations. For RDF Stream Processing (RSP) in particular, RSP engines empirically proved the approach feasibility and paved the road to application design and comparative analyses. Observing these real systems highlighted their heterogeneity and fosters new foundational achievements: RSP-QL, i.e. a...
متن کاملRSP-QL Semantics: A Unifying Query Model to Explain Heterogeneity of RDF Stream Processing Systems
RDF and SPARQL are established standards for data interchange and querying on the Web. While they have been shown to be useful and applicable in many scenarios, they are not sufficiently adequate for dealing with streams of data and their intrinsic continuous nature. In the last years data and query languages have been proposed to extend both RDF and SPARQL for streams and continuous processing...
متن کاملRelational Schema Protocol (RSP)
This document specifies the Relational Schema Protocol (RSP). RSP enables loosely coupled applications to share and exchange relational data. It defines fixed message format for an arbitrary relational schema so that the changes in the data schema do not affect the message format. This prevents the interacting applications from having to be reimplemented during the data schema evolvement. This ...
متن کاملA higher-order semantics for OWL 2 QL ontologies (Extended abstract)
Recent OBDA projects have pointed out that one of the drawbacks of OWL 2 is the lack of metamodeling and metaquerying capabilities, i.e., features for specifying and reasoning about metaconcepts and metaproperties [1]. Roughly speaking, a metaconcept is a concept whose instances can be themselves concepts, and a metaproperty is a relationship between metaconcepts. Although OWL 2 provides syntac...
