NAME

Module::Install::DOAPChangeSets::Format - vocabulary guide

DOAP CHANGESETS FORMAT

DOAP Changesets are written in RDF - normally serialised as Turtle, though other serialisations are fine. (The Module::Install::DOAPChangeSets module supports any input format recognised by RDF::Trine.)

This document assumes a good working knowledge of RDF and Turtle.

You would normally describe your project in a file called "meta/changes.ttl" from which a changelog called "Changes" will be automatically built at packaging time.

Namespaces

You will want to define at least the following namespaces:

@prefix :     <http://usefulinc.com/ns/doap#> .
@prefix dc:   <http://purl.org/dc/terms/> .
@prefix dcs:  <http://ontologi.es/doap-changeset#> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix xsd:  <http://www.w3.org/2001/XMLSchema#> .

And you should define a namespace specific for your distribution:

@prefix my:   <http://purl.org/NET/cpan-uri/dist/Example-Example/> .

Describing the Changeset Document

You should now give the Changeset document itself a description. At a minimum, you must set the dc:subject.

<>
  dc:title     "Changes for Example-Example" ;
  dc:subject   my:project ;
  dc:creator   my:developer .

Describing the First Release of the Distribution

Use DOAP to describe the first version of the distribution. At the very least you need to include its revision (version number):

my:v_0-01
  a           :Version ;
  dc:issued   "2007-12-20"^^xsd:date ;
  :revision   "0.01"^^xsd:string .

You would not normally list any changes against the first release, as nothing has been changed.

Describing Subsequent Releases

For subsequent releases, you add a changeset to a release description:

my:v_0-02
  a           :Version ;
  dc:issued   "2007-12-29"^^xsd:date ;
  :revision   "0.02"^^xsd:string ;
  rdfs:label  "The 0.02nd Coming" ;  ## a "title" for the release
  dcs:changeset [
    dcs:item
      [ rdfs:label "Example change." ] ,
      [ rdfs:label "Example bugfix." ; a dcs:Bugfix ] ,
      [ rdfs:label "Example new feature." ; a dcs:Addition ] ,
      [ rdfs:label "Example removal." ; a dcs:Removal ] 
  ] .

Describing the Distribution

Use DOAP to describe the distribution. At the very least you need to assert that the project is a Project and provide a name for it. You must also list all the releases you wish to appear in the human-readable Changes file generated by the Module::Install::DOAPChangeSets module. There are plenty of other properties in DOAP which you can also use.

my:project
  a           :Project ;
  :name       "Example-Example" ;
  :shortdesc  "Just an example!" ;
  :programming-language "Perl" ;
  :created    "2007-12-18"^^xsd:date ;
  :maintainer my:developer ;
  :homepage   <http://search.cpan.example.org/dist/Example-Example/> ;
  :bug-database <http://rt.cpan.example.org/Dist/Display.html?Queue=Example-Example> ;
  :release    my:v_0-01 , my:v_0-02 .

Describing a Developer

Developers should be described using FOAF. At the very least, include a name. A CPAN e-mail address is also a good idea.

my:developer
  a           foaf:Person ;
  foaf:name   "Joe Bloggs" ;
  foaf:mbox   <mailto:joebloggs@cpan.example.org> ;
  foaf:page   <http://search.cpan.example.org/~joebloggs/> .

Legacy Support

The module has legacy support for Aaron Cope's "changefile" vocab, but this is not thoroughly tested. Changelogs written in this vocab tend to use DOAP incorrectly, so I discourage using this vocab.
