Try to remove Tomcat's cache ( $TOMCAT/webapps/KIM/ , $TOMCAT/work/* )
Also make sure, that the class "drill_fluid_additive" is visible, that
is - this statement exists in the semantic repository:
<drill_fluid_additive>
<http://www.ontotext.com/kim/2006/05/kimso#visibilityLevel1> "" .

Hello, Philip,
Question 1 and 3 have been solved, but it seems question 2 is
still unresolved. In Protege, I have added Drill_fluid_additive as a
domain of producedBy, but in WebGUI it still doesn't show up...
Thank you so much for your help!

Hello, Philip,
Please find the attached file. In this file, there are
three "drill_fluid_additive" instances whose names begin with "SAFE".
All classes and properties have been defined in protont,owl properly
(and with a rdfs:label attribute for each class, in particular,
drill_fluid_additive is defined as a subclass of protont#material
which is a subclass of protont#object), and declared visible. After
importing this file by toolRDFImport.cmd, I have the following
problem:
1. query: query instances for all "drill_fluid_additive",
all instances are retrieved; query instances for all
"drill_fluid_additive" starting with "SAFE", no result is returned.
The same problem occurs when I use these triples (either in RDF or in
N-Triple format) as a separate knowledge base that loaded by Sesame,
instead of importing triples by toolRDFImport.
Basically, KIM operates in two modes - using labels, or aliases. This is
configured in $KIM_HOME/config/install.properties in
com.ontotext.kim.KIMConstants.ENTITY_DESCR property.
- Labels - more simple and more compact. Generally what is required is that
each entity has at least a protons:mainLabel, and different optional
rdfs:label descriptions.
- Aliases - uses aliases, which are objects by themselves, to describe the
entities. The idea is to be able to have meta information for the labels.
This is the default model KIM uses.
In your case you provided a label, but your model is most probably
"Aliases". And, of course, you should also provide a mainAlias/mainLabel .
2. In Protege, I define a restriction "producedBy" for
drill_fluid_additive, linking the entity to its manufacturers, but in
WebGUI, after selecting X as an entity of "drill_fluid_additive", I
cannot select property "producedBy" in the drag-down box below it. But
for other three properties (e.g., primaryFunction, etc.) I can. I am
wondering why.
Try setting "drill_fluid_additive" as a domain of the property "producedBy"
.
3. The manufacturer locates in Houston, TX. How can I relate
the "Houston" in this newly imported RDF to the city "Houston" defined
in KIM wkb.nt? Because I want to take advantage of the underlying
geographic information in KIM.
Use the URI of Houston from the wkb.nt :
<Manufacturer> <http://proton.semanticweb.org/2006/05/protont#locatedIn>
<http://www.ontotext.com/kim/2006/05/wkb#City_T.2949> .
Thank you so much for your help!

Hope this helps,
Philip
