Hi Michael,
the mapping.xls is for mapping infoboxes to ontology classes and infobox
properties to ontology properties. The rules.xls keeps track of
exceptions to the definitions in the mapping.xls. Both files are
documented in the SVN ontology/docs files. If you make any changes to
the xls files you need to rerun the database import scripts in the SVN
ontology directory.
As defined in the mapping file (.xls) keyPerson on Organisation
has the range Person.
If you want to change the MappingBasedExtractor (former Generic
Extractor) to ignore tags, you might want to use the Util class and its
functions. For the keyPerson case find the corresponding code for object
properties in the MappingBasedExtractor ( "switch($property_type) {" )
and define own replacements. The Util class offers a function called
removeHtmlTags which might be useful.
Hope this helps,
Anja
