nexml RDFa representation standard

Arlin and Rutger, June 30, 2009

I'm going to put the transcript of our chat here until I'm done with this (arlin 17:25, 30 June 2009 (EDT))

• hello

Rutger Vos

• ok
• ah, good
• example

<meta content="Bodner M." datatype="xsd:string" id="meta225913" property="dc:contributor"  xsi:type="nex:LiteralMeta"/>

• example

<otu about="#otu225924" id="otu225924" label="Zenodorus cf. orbiculatus">
<meta href="taxon/uBio:3546132" id="meta225927" rel="dc:relation" xsi:type="nex:ResourceMeta"/>
</otu>

• so the triple is <#otu225924> <dc:relation> <taxon/uBio:3546132>
• example

xml:base="http://8ball.sdsc.edu:6666/treebase-web/phylows/"

• treebase file you can get

http://8ball.sdsc.edu:6666/treebase-web/phylows/taxon/uBio:3546132

• @content == @href == enclosed elements
• object can be @content, @href, or raw xml inside meta element
• example

<meta href="taxon/uBio:3546132" id="meta225927" rel="dc:relation" xsi:type="nex:ResourceMeta"/>

• example

<link href="taxon/uBio:3546132" id="meta225927" rel="dc:relation" xsi:type="nex:ResourceMeta"/>

• example

<link href="taxon/uBio:3546132" id="meta225927" rel="dc:relation"/>

• example

<meta content="Bodner M." datatype="xsd:string" id="meta225913" property="dc:contributor"/>

• This is the nasty example of packing two triples in one element. Not to be emulated

<tree id="foo1" about="foo2" xmlns:bs="http://banana.split.org/ontology/example#">
 <annotation rel="bs:myotherterm" href="http://uri.to.somewhere.org/123"
          property="bs:myterm">My Literal value</annotation>
</tree>

• but this is about what we want, right?

<otu id="foo1" about="foo2" typeof="tc:TaxonConcept"  xmlns:tc="http://rs.tdwg.org/ontology/voc/TaxonConcept#" xmlns:tn="http://rs.tdwg.org/ontology/voc/TaxonName#">
   <meta rel="tc:hasName">
      <meta typeof="tn:TaxonName" about="urn:lsid:ipni.org:names:333114-1:1.5">
         <meta property="tn:genusPart">Rhododendron</meta>
         <meta property="tn:specificEpithet">ponticum</meta>
         <meta property="tn:authorship">L.</meta>
      </meta>
 </meta>
</otu>

• or better

<otu id="mylocal_id1234" about="#mylocal_id1234" typeof="tc:TaxonConcept"

<meta rel="tc:hasName" xsi:type="nex:ResourceMeta">

<meta rel="tc:hasName" id="my_local_meta12345" xsi:type="nex:ResourceMeta">

Rutger Vos

<meta rel="tc:hasName" xsi:type="nex:ResourceMeta" id="meta3242">

• use inria rdfa extractor
• use xsltproc
• like this "xsltproc RDFa2RDFXML.xsl <filename>"
• erdfa
• this is my script

#!/usr/bin/perl
use strict;
use warnings;
die "Need infile(s) to extract RDFa from" unless @ARGV;
my $xsltproc = $ENV{'XSLTPROC'} || 'xsltproc';
my $xsl = '/Users/rvosa/Documents/workspace/nexml/trunk/nexml/xslt/RDFa2RDFXML.xsl';
exec( $xsltproc, $xsl, @ARGV );
