Problems / Issues

  • standard RDF export must have a XSLT post processing to get better RDF
  • manual RDF export with {{#ask:… foramt=rdf}} produces too erratic URLs (depending on what properties are set and not set on a page)
    alternatively one could keep the URL constant in #ask-ing all wanted properties, even if they are not set
  • Extension:Data Transfer might be a work around but it is based on the export of: category ↔ page ↔ template ↔ parameter and produces (nested) XML. It can also export properties, but this export is just the property page itself (see generated URL of Category:Species on www.nematodes.org).
    Example output of template data of the category Species (http://www.nematodes.org) …
    XML output of identical data showing data from category “Species” on http://www.nematodes.org

    • using nested templates or nested forms, nested XML should be possible to export
    • the problem may be to map template parameter

Proposed mappings, actions / Open questions

Some questions relate to using correct SMW data types (see Help:Recommendation for setting Data Types in Semantic MediaWiki)

Property Notes/ Proposed action
property:terms-2Dinternal… delete
swivt:wikiNamespace delete
swivt:specialProperty_ERRP delete; is "Has improper value for" but is not (yet) defined in the Semantic Wiki Vocabulary and Terminology. Note: URLs with a #-character for data type URL produce wrongly this error. In SMW version 1.8 this is corrected.
swivt:specialProperty_IMPO is related to "Imported from"; probably delete (?or use it to extract information); this is not defined either in the Semantic Wiki Vocabulary and Terminology
swivt:Subject is the Wikipage (skos:Concept in this case), depending on the page source:
  • translate to skos:Concept depending on the page source
  • translate to skos:Collection depending on the page source
  • …
swivt:page + 2 × rdfs:isDefinedBy
  • swivt:page + rdfs:isDefinedBy are of the same information, e.g.
    <swivt:page rdf:resource="http://terms.gbif.org/wiki/dwc:catalogNumber"/> is equivalent to the (automatically) inserted
    <rdfs:isDefinedBy rdf:resource="http://terms.gbif.org/wiki/Special:ExportRDF/dwc:catalogNumber"/>
    … so delete one of them (swivt:page)?
  • rdfs:isDefinedBy is set twice:
    1. once (automatically) inserted but pointing to the page RDF e.g.:
      <rdfs:isDefinedBy rdf:resource="http://terms.gbif.org/wiki/Special:ExportRDF/dwc:catalogNumber"/> and
    2. produced by template:Concept e.g.
      <rdfs:isDefinedBy rdf:resource="http://rs.tdwg.org/dwc/terms/"/> by {{Concept | is defined by = … }}
So the first means “is (technically) defined by this Wiki page” and the latter means “is (originally) defined”. How to deal with this?
rdfs:range data type URL or Page? pro Page: if we have Wiki pages (=rebuild external vocabulary). Note: [[Imported from::…]] changes the rdfs:isDefinedBy to be the external URL; pro URL: if we use just external URL or internal URLs
  • I set it to URL (Andreas Plank 10:44, 15 November 2012 CET). Use {{Complete pagename to fullurl| PAGENAME}}. Note: there is a bug http://terms.gbif.org/wiki/dwc:catalogNumber becomes sometimes (ecach time?) http://localhost/dwc:catalogNumber. It can only be corrected by purging and open the page in editing mode and save it unchanged (do this several times)
dcterms:modified this is of data type String because SMW data type Date can not handle data ranges 2007-11-13/15, rdf export looks like:
<dcterms:modified rdf:datatype="http://www.w3.org/2001/XMLSchema#string">2007-11-13/15</dcterms:modified>
