The PhpWiki SemanticWeb implementation follows closely the implementation of the semantic Mediawiki extension. 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 numeric attributes.
  • Support for using physical units of measurement in all numerical attributes, without need for prior configuration.

Relations can be searched for with regular expressions, attributes can be searched for with full mathematical expressions.

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 syntax:



Attributes are defined as link to numbers (understandable by GNU Units) 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, attributes not.


Sample taken from

San Diego [is_a::city] located in the southwestern corner of
[California|located_in::California], the extreme southwestern corner
of the [United States|country::United States]. It is the county seat
of San Diego County. As of the 2000 census, the city had a total population of

of Finance estimated the city to have 1,305,736 residents. The city
is the second-largest in California and the seventh-largest in the
United States and is noted for its temperate climate and many beaches.

According to the United States Census Bureau, the city has a total
area of [963.6 km²|area:=963.6 km^2] (372.0 mi²). 840.0 km²
(324.3 mi²) of it is land and 123.5 km² (47.7 mi²) of it is water.
The total area is 12.82% water.

Most notably, San Diego is the location of the 2005 International
