Re: schema.org Markup for DITA XML-based Technical Documentation

A use case is enrichment of technical documentation content with identifiers for named entities. These may provide links to general data sets or to specific ones, e.g. provided by the tech doc company.

I have explored this with others and produced this demo, showing the process with docbook and other XML vocabularies. I will present a DITA demo at this years TCWorld conference in autumn.
See the demo here

Choose in the demo the approach 2 „embed linked data via structured markup“. This uses not RDFa but micro data attributes, but this is just syntactic sugar. See an XLIFF example below.

<xliff xmlns="urn:oasis:names:tc:xliff:document:2.0" version="2.0" srcLang="en" trgLang="fr">
 <file id="f1">
  <unit id="u1">
   <segment>
   <source>We very much welcome you in the city of <mrk vocab="http://schema.org/" typeof="Place" property="name" resource="http://dbpedia.org/resource/Prague">Prague</mrk>, a home of XML!</source>
   </segment>
  </unit>
 </file>
</xliff>

See the approach 4 in the demo. This does not embed RDF/XML but turtle, changing this to RDF/XML is no big issue.

See approach 5 for a json-ld example - the information is stored as web annotation.

All use cases in above demo are related to SEO. The different approaches are supplied because they have different influences on existing XML workflows, e.g. may (or may not break) validation.That topic will be explored further in a new CG, see

Though not designed with SEO in mind, Colin Maudry's DITA OT plugin that produces RDF seems to me to be a natural stepping stone to producing content in RDFa that Schema.org <http://schema.org/> could parse, though asking for Schema.org <http://schema.org/>-aware descriptors to be built into the DITA-OT is also a possibility.

It is primarily (but not exclusively) used by technical writing departments to produce content. It is estimated to be used by somewhere between 5-10% of all technical writing groups, mainly with medium- to large-firms. The standard is open, and is managed by OASIS (https://www.oasis-open.org/committees/dita/ <https://www.oasis-open.org/committees/dita/>).

Best Practices suggests that each topic come with a short description, so it is possible to easily identify the type of topic and what it describes.
