Streamable RDF Serialization Formats for All Devices

This proposal outlines requirements and formats for RDF serialization, ensuring stream-ability, scalability, and extensibility for powerful and resource-constrained devices. Includes recommendations for RDF/XML, Turtle, N3, and N-Quads formats. Explore abstract data representation and transformations using XML Infoset and W3C EXI for efficient processing.

  1. W3C RSP Serializiation 29.7.2014

  2. TOC • Requirements • RDF Formats • Evaluation • Proposal

  3. Requirements • Serialization format shall be stream-able • Direct data retrieving (e.g., for querying) from the stream • Scalable • applicable for powerful devices and • for resource-constrained embedded devices (sensors, actuators, etc.) • Extendable (for time stamps or intervals) • extend syntax or include new values?

  4. RDF Formats W3C Recommendations: • RDF/XML first standard format (based on XML Infoset) • Turtle is a subset of Notation3 (N3) • N3 is a shorthand (non-XML) serialization of RDF • N-Quads also a subset of N3; supports multiple RDF Graphs • N-Triples line based format • (JSON-LD?)

  5. Requirements & Formats

  6. Proposal for RSP? • No fix data serialization format, however, abstract data representation using XML Infoset  plain-text RDF/XML can be used  efficient RDF with W3C EXI can be used for resource-constrained devices  simple transformations to other representations formats such as Turtle, N3, etc.
