First Public Working Draft: RDF Dataset Canonicalization

RDF Dataset Canonicalization

Published by
 RDF Dataset Canonicalization and Hash Working Group

Abstract

RDF [RDF11-CONCEPTS] describes a graph-based data model for making claims about the world and provides the foundation for reasoning upon that graph of information. At times, it becomes necessary to compare the differences between sets of graphs, digitally sign them, or generate short identifiers for graphs via hashing algorithms. This document outlines an algorithm for normalizing RDF datasets such that these operations can be performed.

Status of the Document

This section describes the status of this document at the time of its publication. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at https://www.w3.org/TR/. 

This document describes the URDNA2015 algorithm for canonicalizing RDF datasets, which was the input from the W3C Credentials Community Group published as [CCG-RDC-FINAL]. There are other canonicalization algorithms actively being considered by the Working Group – notably [Hogan-Canonical-RDF]; future versions of this document may change accordingly. See Issue 6: Compare the two algorithms, and decide on basis for our work and Issue 10: C14N choice criteria for further discussion. 

This document was published by the RDF Dataset Canonicalization and Hash Working Group as a First Public Working Draft using the Recommendation track.

Publication as a First Public Working Draft does not imply endorsement by W3C and its Members.

This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.

This document was produced by a group operating under the W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent.
