The PhpWiki:SemanticWeb implementation follows closely the semediawiki implementation. It features:
- Annotation of article-article-links by means of configurable relations (link-types).
- Annotation of articles with simple data-values that are assigned to configurable attributes.
- Support for using physical units of measurement in all numerical attributes, without need for prior configuration.
The annotation data will be combined with annotations from the current category system to generate standard-compliant OWL/RDF output, which can be fully processed with tools that support OWL DL or OWL Lite, but which can also be treated in a meaningful way by software that supports RDF, RDFS or XML.
Relations (link-types) are defined as link with the following markup syntax:
Attributes are defined as link with the following markup syntax:
Attributes and relations refer only to the current page - the current page is the subject, the relation the predicate, the linked page the object in a RDF triple. Relations always refer to another page - they must not exist. Attributes not, since they are numeric only.
With the SemanticSearch feature you can query online simple and complex facts.
You can import and export lists of facts or queries, as format rdf, rdfs, owl.
