Problem

• import/export OWL ontology using wiki dump xml file . Note: halo extension gardening has done similar stuff, but we can do it using JAVA
• import/export RDF instance data, further make it an Named Entity store. Note, this is kind of Dbpedia work.

Test

• investigate wiki dump file structure
  1. check Special:SpecialPages in left toolbox,
     • Special:Export
     • Special:Import
  2. create several example files in wiki
  3. export the files out in XML
  4. update the exported XML and import them
  5. create new entries in exported XML and import them

• convert RDFS to Wiki dump xml file, http://www.w3.org/2000/01/rdf-schema
  • naming convention: wiki page name should be (prefix:localname). e.g. http://www.w3.org/2000/01/rdf-schema#Class should be named as rdfs:Class
  • blank node will have a auto id.

Note: we do not expect any inference on OWL ontology during convention
