Announcing the birth of the W3C RDF stream processing community group

Several initiatives have been proposed in the literature for the production, transmission and continuous querying of RDF data streams. In general, each of them proposes its own model for the representation of RDF streams, its own query language and evaluation semantics, and several implementations of systems that are able to handle RDF data streams, with their own advantages and limitations. The mission of the W3C RDF Stream Processing Community Group (RSP) is to define a common model for producing, transmitting and continuously querying RDF Streams. This includes extensions to both RDF and SPARQL for representing streaming data, as well as their semantics. Moreover this work envisions an ecosystem of streaming and static RDF data sources whose data can be combined through standard models, languages and protocols. Complementary to related work in the area of databases, this Community Group looks at the dynamic properties of graph-based data, i.e., graphs that are produced over time and which may change their shape and data over time. In this talk we will summarize the motivation for the creation of the group, the group's main objectives and the expected outputs.
