RDF Dataset Canonicalization and Hash 1.0 Processor Conformance

Abstract

This document report test subject conformance for and related specifications for RDF Dataset Canonicalization and Hash 1.0 Test Suite according to the requirements of the Evaluation and Report Language (EARL) 1.0 Schema [EARL10-SCHEMA].

This report is also available in alternate formats: Turtle and JSON-LD

Introduction

This implementation report covers the implementations of the RDF Dataset Canonicalization and Hash 1.0 specifications which have submitted test results. It is intended to be maintained by the RDF Dataset Canonicalization and Hash Working Group. The implementation report serves two purposes:

To demonstrate that there are multiple, independent implementations of the specifications. This is a prerequisite for progression of any standard to Recommendation.
To catalog the known, conforming implementations and which features each supports.

There may be other implementations which are not listed in this report, either due to not submitting tests or by not being intended as direct implementations of the specification, but instead layering on top of such libraries.

Instructions for submitting implementation reports

Reports should be submitted in Turtle format to Public RCH WG or via a Pull Request to the w3c/rdf-canon.

Tests should be run using the test manifests defined in the Test Manifests Section.

Include an earl:Assertion for each test, referencing the test resource from the associated manifest and the test subject being reported upon. See the example below:

  [ a earl:Assertion;
    earl:assertedBy <--your-developer-identifier-->;
    earl:subject <--your-software-identifier-->;
    earl:test <--uri-of-test-from-manifest>;
    earl:result [
      a earl:TestResult;
      earl:outcome earl:passed;
      dc:date "2023-01-25T10:18:04-08:00"^^xsd:dateTime];
    earl:mode earl:automatic ] .

The Test Subject should be defined as a doap:Project, including the name, homepage and developer(s) of the software (see DOAP). Optionally, including the project description and programming language. An example test subject description is the following:

  <> foaf:primaryTopic <--your-software-identifier--> ;
    dc:issued "2016-12-26T10:18:04-08:00"^^xsd:dateTime ;
    foaf:maker <--your-developer-identifier--> .

  <--your-software-identifier--> a doap:Project, earl:TestSubject, earl:Software ;
    doap:name          "My Cool RDF Canonicalizer" ;
    doap:release [
      doap:name     "--short name wih version number--";
      doap:revision "--Software version number--" ;
      doap:created  "2020-02-19"^^xsd:date;
    ] ;
    doap:developer     <--your-developer-identifier--> ;
    doap:homepage      <--your-software-homepace--> ;
    doap:description   "--your-project-description--"@en ;
    doap:programming-language "--your-implementation-language--" .

The software developer, either an organization or one or more individuals SHOULD be referenced from doap:developer using FOAF. For example:

  <--your-developer-identifier--> a foaf:Person, earl:Assertor;
    foaf:name "--My Name--";
    foaf:homepage <--my homepage--> .
