classify wine.owl


Hi

I try to use Protege 2.0 Beta (102 110 111).

Classification of the koala.owl ontology with Racer is succesfull but I
get errors with the wine.owl ontology.
What is wrong : something special in the wine.owl, in Racer, in my
configuration ?

Thanks everyone

Christine

Instance table widget still broken in build 111


I really like the concept behind the instance table widget in Protégé 2.0.
However, its customization is not quite working yet [but you probably
already new that].  In particular, trying to rearrange the columns (or
select one and remove it) gives several different kinds of exceptions.

Is there any idea when it will working better?  I'm anxious to show it to
some users.

Re: Slots for subclasses


Thanks Daniel. 
That is what I was looking for. I have an additional question. Does doing this put the new "Allowed Parent"
together with the ones which existed from before in the code generated?
Yes I understand that this way sounds a bit awkward but it is because we are trying a new way to represent
processes and activities, at clinical guidelines and gene ontology levels, that is why such situations
are arising.

winx007, whoever you are :-), Daniel has answered the question and if you do the way he says you should be able
to add additional allowed parents to a subclass.

Kind Regards,
Anand.

Assuming I'm understanding your question, I think you are asking about 
altering allowed parents in a slot that is inherited. If you view the slot 
at the class (the yellow "V" button), then you can only change the allowed 
parents to be subclasses of the original value. But if you need add other 
parents, then you need to view the slot unattached with the class (the 
green "V" button). You should think carefully about what this means 
semantically in your situation, as generally your ontology should conform 
with the former case.

Protege Plug-in


Hello, I'm trying to make some changes in the plug-in of XML Schema (Storage
Backends), but, when I try to compile it Java said me that can't find
org.apache.xerces.readers class. Does somebody know what could be the
problem? I've tried to include the JAR files of the Protegé version in which
the plug-in works in the Classpath, but the problem persists.

Thanks in advance and best regards, Ismael

Re: Protege Plug-in


Hi Ismael,

You need to have xercesImpl.jar and xmlParserAPIs.jar in your classpath.

Re: OWLException: Data cardinality restriction.


Hi Martin,

sorry for the delay - we have celebrated celebrated
Thanksgiving, which is one of the very few long weekends
in the Unites States.  No comparison with Germany though :(

Unfortunately, I can't help instantly without having
more information about the ontology that you wish to
classify.  Could you either send the owl file to me
privately (due to attachment restrictions) or provide
further details on your ontology (e.g. with a relevant
source code snippet)?  I tried to use cardinality(=)
restrictions in a toy ontology, and it works fine.

You certainly already know that you can select the value type
"Class" as the range for a property.  This already allows you to
create links between classes (e.g. if you define Dog and Cat
as subclasses of DomesticAnimal).  There is no mechanism in
OWL to define which classes could be takes as values for a
class property, though.  I think you don't need to use class
ranges if you try to convert instances in your ontology into
classes (e.g. as suggested above).  With only classes you
can also (later) benefit from the classifier.  You can in many
cases convert instances into classes (e.g. cats are domestic
animals with the following restrictions:...).  And then you
have the specific instances of Cat, such as Minka and Purzel.

General questions about Ontology use


Hello All,
I've some questions about ontology and its use:
1) If I take for example wine.owl antology and I want Know all Knowledge 
about white wine (winery that produces it, compatible foods...), 
is possible export, all and only the regarding requests my specific 
domain, like a new sub-ontology?
2) Is possible manage online an ontology, create a sub-ontology(like a 
specific model), working on and saving, always online, the modifications?
I hope of to have been clear in exposing my concepts, but English isn't my 
natural language.

Kind Regards
Leonardo Miglietta

How reverse XML schema into Protege2000


Hi,all

   So far, I had done a domain ontology and its application with Protege 2000.
Hopefully, it may be published the world-wide web in furture. I choice XML
schema as a save format. However, though the XML schema can enables a Protege
knowledge-base to be saved as an XML document, why I can not import the XML
document into Protege,  in other words, how can we reverse a set of classes and
instances in a knowledge-base(protege2000) which correspond to the entries in
the XML document?

Look forward to your help
Thanks

Re: How reverse XML schema into Protege2000


It's not clear from your question whether:

a). You are having trouble opening a project file that was saved using the 
XML Schema Backend.  If this is the case, please contact the authors of the 
back-end directly.  Their contact information is available in our 
Contributions Library.

-- OR --

b).  You want to create ontologies in Protege by reading-in arbitrary XML 
document instances.  If this is the case, Protege doesn't have built-in 
support for this yet but you could look at the XML Tab Widget in our 
Contributions Library (http://protege.stanford.edu/plugins.html).  It is no 
longer supported but works well enough that you could probably read your 
document instances into Protege successfully and then make any necessary 
modifications.
