NAME

6       RDF::TrineX::Parser::Pretdsl - the Perl RDF Extended Turtle
7       Domain-Specific Language
8

DESCRIPTION

10       Pretdsl is a domain-specific language for describing Perl projects (in
11       particular CPAN releases) in RDF triples. It can be seen as an enhanced
12       version of Turtle/N3, or an application of ShorthandRDF.

63       Predefined terms
64
65       Like how Turtle defines "a" as a term that expands to rdf:type, Pretdsl
66       defines some terms:
67
68               # Generally useful predicates
69               @term label    rdfs:label .
70               @term comment  rdfs:comment .
71               @term seealso  rdfs:seeAlso .
72
73               # Makefile predicates
74               @term abstract_from          cpant:abstract_from .
75               @term author_from            cpant:author_from .

83               @term requires               cpant:requires .
84               @term requires_external_bin  cpant:requires_external_bin .
85               @term recommends             cpant:recommends .
86               @term test_requires          cpant:test_requires .
87               @term configure_requires     cpant:configure_requires .
88               @term build_requires         cpant:build_requires .
89               @term provides               cpant:provides .
90
91               # Changelog predicates
92               @term issued     dc:issued .
93               @term changeset  dcs:changeset .
94               @term item       dcs:item .
95               @term versus     dcs:versus .
96
97               # Changelog datatypes
98               @term Addition            pretdsl-dt:Addition .

109               @term Update              pretdsl-dt:Update .
110
111       XSD datatype shorthands
112
113       Like how Turtle has shorthands for literals of type xsd:integer,
114       xsd:double and xsd:boolean, such that they don't need quoting or an
115       explicit datatype, Pretdsl defines shorthands for xsd:date and
116       xsd:dateTime.
117
118       For xsd:date, just use YYYY-MM-DD format. For xsd:dateTime, use
119       YYYY-MM-DDThh:mm:ss.sss+zzzz (seconds must be included, but fractions
120       of seconds are optional; timezones are optional, and 'Z' is supported
121       for UTC).
122
123       Perl-specific datatype shorthands
124
125       Pretdsl defines a special quoting style for Perl-specific resources.  A
126       quoted resource starts and ends with a backtick (`). The first backtick
127       may also be preceded by a single letter which is used for
128       disambiguation.
129
130       Distributions:
131
132               `HTML-HTML5-Parser`
133               d`HTML-HTML5-Parser`
134
135       Releases:
136
137               `HTML-HTML5-Parser 0.200`
138               `HTML-HTML5-Parser 0.200 cpan:TOBYINK`
139               r`HTML-HTML5-Parser 0.200`
140               r`HTML-HTML5-Parser 0.200 cpan:TOBYINK`
141
142       Files:
143
144               `./README`      # needs to contain a slash to disambiguate
145               `xt/test.pod`   # with distributions
146               f`README`       # or use explicit disambiguating letter
147
148               # Files may be qualified with a release...
149               f`README HTML-HTML5-Parser 0.200 cpan:TOBYINK`
150
151       Modules:
152
153               `HTML::HTML5::Parser`
154
155               # The following are semantically identical
156               m`HTML::HTML5::Parser`
157               f`lib/HTML/HTML5/Parser.pm`
158
159               # And so this is fine too...
160               m`HTML::HTML5::Parser HTML-HTML5-Parser 0.200 cpan:TOBYINK`
161
162               # Trailing "::" can disambiguate
163               `JSON::`
164
165       Packages:
166
167               # Always need the disambiguation letter to avoid confusion
168               # with modules
169               p`HTML::HTML5::Parser`
170
171       The line between packages and modules is a little blurred. Future
172       versions of Pretdsl may also provide datatype shorthands for classes
173       and roles (in the Moose/Mouse sense).
174
175       CPAN IDs:
176
177               # It looks like a qname, but it's not. It's a case-insensitive
178               # literal shorthand
179               cpan:TOBYINK
180               cpan:tobyink
181
182       RT Bugs:
183
184               # No the hash below doesn't start a comment.
185               RT#12345
186
187       The Switch-a-Roo
188
189       All the Perl-specific datatypes, plus the changelog datatypes mentioned
190       above are intercepted during the parse, and being added to the model as
191       literals, they are replaced with blank nodes and URIs, and enriched
192       with additional triples.
193
194       So the following Pretdsl which appears to have a literal subject:
195
196        `Example-Distribution 0.001 cpan:TOBYINK`
197            issued 2012-06-18 .
198
199       May be equivalent to the following Turtle:
200
201        <http://purl.org/NET/cpan-uri/dist/Example-Distribution/v_0-001>
202            a doap:Version ;
203            dcterms:identifier "Example-Distribution-0.001"^^xsd:string ;
204            doap:revision "0.001"^^xsd:string ;
205            dcs:released-by cpan:tobyink ;
206            doap:file-release <http://backpan.cpan.org/authors/id/T/TO/TOBYINK/Example-Distribution-0.001.tar.gz> ;
207            dcterms:issued "2012-06-18"^^xsd:date .
208
209        <http://purl.org/NET/cpan-uri/dist/Example-Distribution/project>
210            doap:release <http://purl.org/NET/cpan-uri/dist/Example-Distribution/v_0-001> .
211
212   About the Parser
213       The parser provides the same API as RDF::Trine::Parser::Notation3.
