Challenges & Opportunities of RSP-QL Implementations
نویسندگان
چکیده
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 our implementation experience and we discuss the research opportunities they imply. For each of these challenges, we also formulate some hypotheses that will drive our future work empirical studies on RSP.

RSP-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 کاملRepresenting RDF Stream Processing Queries in RSP-SPIN
A number of RDF Stream Processing (RSP) systems have been developed to support processing of streaming Linked Data, however, due to the lack of a standard query language they all provide different extensions. The RSP Community Group is in the process of standardizing the RSP query language (RSP-QL), which incorporates many features from existing RSP languages. In this paper we present a demo sh...
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 کاملA Query Model to Capture Event Pattern Matching in RDF Stream Processing Query Languages
The current state of the art in RDF Stream Processing (RSP) proposes several models and implementations to combine Semantic Web technologies with Data Stream Management System (DSMS) operators like windows. Meanwhile, only a few solutions combine Semantic Web and Complex Event Processing (CEP), which includes relevant features, such as identifying sequences of events in streams. Current RSP que...
متن کاملQuery Templates for RDF Stream Processing
In recent years there has been a growing interest in using Semantic Web technologies to process streaming information, and several RDF Stream Processing (RSP) systems have been developed to bridge the gap between static and streaming Linked Data. However, the lack of a standardized query language makes testing and benchmarking of systems difficult, since queries need to be developed for each su...
