[protege-discussion] Re: [protege-discussion] Unable to Export to Oracle 9.2 database using the JDBC backend with Protégé 2.1.1 (or prior)


My guess would be a jdbc driver problem. Make sure that you have the 9.2 
Oracle JDBC driver.  We have tested with Oracle 9.X (9.1 I think) and it 
works but I seem to remember some driver version strangeness.

computed slot values


Hi All,

I have some questions about the Protégé/OWL framework for computing slot values. I've been developing a
prototype that (among other things) allows formulas written in python to be specified for a given
Cls/Slot pair. 

For a given instance:

* I want the UI to render a visible computed value in an appropriate read-only widget. It looks like I get this
by defining a protégé:valuesComputer, correct? Can I get this if I *only* override the return value of DefaultRDFSlot.isComputed(Instance)?

* I want the UI to redraw if a computed value (may have) changed. Do I get this, too, if I define a
valuesComputer? Seems problematic, not knowing the dependencies of a given computation.  In which case,
what APIs should I call to notify listeners a computed value (may have) changed?  

* I don't want to perform expensive computations unless necessary

* I don't want to store results of such computations (in some cases lots of results for lots of instances)
unless necessary

* I'd rather discover which slot values are computed on the fly (based on the existence of formula
annotation values) rather than having to keep formula and valuesComputer values in sync.

The current implementation departs from the direction suggested by the OWL plugin. 

An OWL annotation property bound to a given Cls is of the form

<property-name> ':=' <python-expression>

 Can you send me the oracle driver jar/zip which works for you . All my drivers 9.2 9.i , 8.1 etc don't work ...
 Could this problem possibly be with the 9.2 database instead (all the discussions seen so far indicate a 9i
or 9.1 implementation)?

I also have trouble with working Jena and Oracle, but another. There is
error on creating model "ORA-01450 maximum key length (string) exceeded" on
my Oracle 8i. That is Oracle in my configuration can't create indexes on
large columns and therefore I use MySQL for Jena persistent models now.

Re: adds object properties but won't show it


Hi,
the "anonymous" term may be not well chosen, the only thing I wanted to 
express is that I can create new properties using the "create object 
properties", but the property frame will not popup (the one in which you 
specify the name, the inverse etc..), neither will this property appear 
in the taxonomy on the left side of Protégé. I'm only able to see these 
properties (anonymous because not named ;) when I do this : save, close 
and open the same project.

Anyway, I put in the PS what I got in the console when try to add a new 
object property, having already a Property hierarchy (one object 
property and two sub object-property).

Here is the ObjectProperty part of the owl file in which you can see the 
"anonymous" property "pizza_ObjectProperty_23"  :
<owl:ObjectProperty rdf:ID="hasBase">
    <rdfs:subPropertyOf>
      <owl:ObjectProperty rdf:ID="hasIngredient"/>
    </rdfs:subPropertyOf>
  </owl:ObjectProperty>
  <owl:ObjectProperty rdf:ID="pizza_ObjectProperty_23"/>
  <owl:ObjectProperty rdf:ID="hasTopping">
    <rdfs:subPropertyOf rdf:resource="#hasIngredient"/>
  </owl:ObjectProperty>

 From a software point of view, I installed everything from the Protégé 
macosx installer.

Cordially,

Yes I mean Violations of PAL constraint and its slots values!
For example:(newspaper_PAL)In the TAB PAL Constraints there are 3 constraints 
(article-section-constraint-by-autor, article-more-than-2-keywords, etc etc)I 
wont show by Protègè java API the Quaries Responses.

XML Literals in protégé-owl


Hello,
I'm quite a novice Protégé user, and I'd like to ask you about  how  to 
use the rdf datatype XMLLiteral for example as the value of a 
restriction of a DatatypeProperty with  Protégé.
My aim is to use XML Literals for encoding in a OWL-DL ontology some 
axioms  that  cannot be expressed directly in description logic but 
require  FOL, Modal Logic ecc. to be expressed through XML markup.
Do Protégé+OWL plugin support XMLLiteral ? Since  I did not find the 
possibility to set  XMLLiteral as the range of my datatype function or 
to create a restriction of it by using "owl:hasValue" directly through 
Protégé,  I've edited manually the OWL file: it has not been changed
by Protégé and the ontology  has been recognised as OWL-DL.
However, the necessary condition displayed by Protégé for the class that 
contains the mentioned restriction to a XMLLiteral value seems to treat 
the markup as if the value were the string resulting by the 
concatenation  of  the  XML  contents.

If you know what I did wrong please give me some advise (I strongly need 
it):
I'll report the lines which I've written:

..........

<owl:Class rdf:ID="myclass">
..........
<rdfs:subclassOf>
   <owl:Restriction>
      <owl:hasValue parseType="Literal"
                     xmlns:s="http://.........."

[Fwd: XML Literals in protégé-owl]

Hello,
For the owl code I sent you I have two obvious errata corrige:
- rdf:parseType (instead of parseType)
- the start-tag "owl:hasValue" is closed after "xmlns:s=..........."
Sorry for there errors.

[protege-discussion] error with generating ontologybeans


 hi,
 I am trying to use ontologybeangenerator with Protege 2000-v 1.9 and JADE
 v.3.1.
 I followed the instructions on the web page of Protege Plugins but I get an
error like ,"No JADE classes found,include SimpleJADEAbstractOntology,and
 arrange Classes accordingly " but I have already included that ontology
 file.

 I will be very glad if you can help me...
 thanks in advance.
