RDF Stream Processing Workshop at ESWC2015

RDF Stream Processing Workshop

In conjunction with the 12th Extended Semantic Web Conference (ESWC 2015)

Motivation

Data streams are an increasingly prevalent source of information in a wide range of domains and applications, e.g. environmental monitoring, disaster response, or smart cities. The RDF model is based on a traditional persisted-data paradigm, where the focus is on maintaining a bounded set of data items in a knowledge base. This paradigm does not fit the case of data streams, where data items flow continuously over time, forming unbounded sequences of data. In this context, the W3C RDF Stream Processing (RSP) Community Group has taken the task to explore the existing technical and theoretical proposals that incorporate streams to the RDF model, and to its query language, SPARQL. More concretely, one of the main goals of the RSP Group is to define a common, but extensible core model for RDF stream processing. This core model can serve as a starting point for RSP engines to be able to talk to each other and interoperate.

Goal

The goal of this workshop is to bring together interested members of the community to:

  • Demonstrate their latest advances in stream processing systems for RDF.
  • Foster discussion for agreeing on a core model and query language for RDF streams.
  • Involve and attract people from related research areas to actively participate in the RSP Community Group.

Each of these objectives will intensify interest and participation in the community to ultimately broaden its impact and allow for going towards a standardization process. As a result of this workshop the authors will contribute to the W3C RSP Community Group Report that will be published as part of the group activities. The workshop results, including the best contributions from the submissions will be published in the ESWC Satellite Events proceedings.

Format

The workshop will provide a forum for the growing community to discuss challenges, current solutions and ideas in RDF stream processing. As such it will mainly consist of both research and technical slots on topics such as complex event processing, query language extensions, and efficient execution approaches for RDF data. There will be a research (lightning talks) session and a show-and-tell (demo) session where the developers of RDF stream processing engines can showcase their latest achievements. Moreover, we also invite application developers to show off their latest uses, extensions, or enhancements of existing engines. Feedback from developers, who use current engines, is highly valuable to advance the state of the art of the community.
A face-to-face meeting of the W3C RSP Community Group focusing on upcoming steps regarding concrete standardization activities will form the conclusion.

Submission Instructions

The main aim of the workshop is to foster new ideas and perspectives on RDF stream processing from related research areas, and facilitate growth and discussion of the W3C RSP Community Group. For this reason, we encourage both research and show-and-tell contributions. Submissions might be:

  • An Expression of Interest (EoI). The EoI should contain author’s expertise, current research interests, relation to the RSP community, and relevance to the broader ESWC audience.
  • A demo or RSP system for the show-and-tell session, including a brief description and how it fits in the RSP spectrum.

Submissions (PDF of 1-2 pages excluding references and title in LNCS format) will be managed through EasyChair using the following URL: https://easychair.org/conferences/?conf=rspworkshop2015

Submissions to the workshop will be published in the W3C RSP site for permanent archival. The best submissions will be selected for publication in the ESWC Satellite Events proceedings.
