Hi, still learing owl and tbc and I am wondering if you could clarify
something for me.
I have an instance called Title with another called Published book
which is a subclass of Source
ie
Owl Thing
Title
Source
PublishedBook
I have added a owl:equivelent class restriction to an object property
hasSource within the Title class, ie hasSource some Source
1) when i run inferencing on a newly added instance of Title that has
no hasSource object assigned, the inferencing infers a blank node as a
source and 8 other blank nodes as members of Source.
2) when the same instance then has a source object assigned to it the
inferred blank node goes away, but I am still left with 8 other blank
nodes that ie: _b1 rdf:type Source, if i run inferncing again these
nodes just seem to multiply.
3) When I remove the restriction completely, I cannot do not see any
blank nodes left over. and all other restrictions (all cardinality
ones) work fine.
Am i missing something , do i have some other restriction configured
wrongly, any help tips or tricks on how to troubleshoot inferencing
issues (i have yet to be able to get a message from the lightbulb)
would be much appreicated.
thanks in advnance
John
