I am trying to import the OWL file, in RSTUdio and I am not successful. And I would like to check how to import ..... and view in Rstudio.
And have the words and classes of this Ontology.

I have two product XML look like:
1:- product-1.xml
.
.
.
.
<images merge-mode="add">
<image-group view-type="large">
<image path="product-123.jpg" />
</image-group>
</images>
.
.
2:- product-1-1.xml
.
.
.
.
<images merge-mode="add">
<image-group view-type="large">
<image path="product-124.jpg" />
<image path="product-125.jpg" />
</image-group>
</images>
.
.
I am importing both the files and I want to append the images for the same product (PRODUCT123) as
<images merge-mode="add">
<image-group view-type="large">
<image path="product-123.jpg" />
<image path="product-124.jpg" />
<image path="product-125.jpg" />
</image-group>
</images>
but it's not appending the images.
I used merge-mode="merge" also for the same but not getting the result as I expected.
Could anyone help me out that where I am doing wrong?
Sadly, what you want to achieve is currently not supported by the Salesforce B2C Commerce platform.
You cannot split the images of an image group into several files and expect that they will be merged.
Indeed, the file import mode should be MERGE, but what you have tried as element merge-mode="add" is not supported, and you should have received a warning when you have imported the file.
If you look at catalog.xsd schema from the documentation you would see the following under complexType.Product.Images type definition:
<xsd:attribute name="merge-mode" type="simpleType.MergeMode" default="merge" use="optional">
<xsd:annotation>
<xsd:documentation>
Used to control if specified image groups will be merged to or replace the existing image specification.
The values "merge" and "replace" are the only ones supported for the "merge-mode" attribute.
Attribute should only be used in import MERGE and UPDATE modes. In import REPLACE mode, using the "merge-mode" attribute is not
sensible, because existing image groups will always be removed before importing the image groups
specified in the import file.
</xsd:documentation>
</xsd:annotation>
</xsd:attribute>
P.S. I would suggest that you look for an alternative solution for merging the data about images before sending it to Salesforce B2C Commerce instance.
Are you using ImportCatalog pipelet? Please check job configuration, import mode should be MERGE.
I have owl file containing some axioms :
<rdfs:subClassOf>
<owl:Restriction>
<owl:onProperty rdf:resource="namespace#Gender"/>
<owl:hasValue>M</owl:hasValue>
</owl:Restriction>
</rdfs:subClassOf>
<rdfs:subClassOf>
<owl:Restriction>
<owl:onProperty rdf:resource="namespace#Address"/>
<owl:minQualifiedCardinality rdf:datatype="&xsd;nonNegativeInteger">1</owl:minQualifiedCardinality>
<owl:onDataRange rdf:resource="&xsd;string"/>
</owl:Restriction>
</rdfs:subClassOf>
For above two axioms protege shows readable string as :
Gender value "M"
Address min 1 xsd:string
The question is how protege generates these readable strings from OWL file ?
Also if I want to create new axiom from these strings how to do that ? (converting axiom to readable string and then convert readable string to axiom back)
The readable format you show is Manchester OWL syntax.
In order to output an ontology in this format, you can use owl api code:
OWLOntology ontology = ...// load or create the ontology
OutputStream out = ... // any output stream will do
ontology.getOWLOntologyManager().saveOntology(ontology, new ManchesterSyntaxDocumentFormat(), out);
out.close();
Parsing a full ontology in Manchester syntax format happens like any other ontology: ontologyManager.loadOntologyFromOntologyDocument() with an input file.
Parsing single axioms is possible but much harder, because the format relies on prefixes set once for a whole ontology; so a lot of setup code is required. I would not recommend doing that as a starter project.
Hello I'm totally newbie in ontology.
I downloaded dbpedia ontology .owl file and open it using topbraid composer.
Topbraid composer shows dbpedia class( owl:Thing -> Activity, Agent, .. etc). Each class also has its own instances.
However, yago2s only provides many .ttl files( yagoSchema.ttl, yagoFact.ttl .. etc).
Cause I think these ttl files are similar to owl file, I also open it using topbraid composer. I expected to see the structure like dbpedia owl file, but it wasn't similar to dbpedia owl file..
They provide schema ttl file, instances ttl file, ... files respectively, but i wanna see the whole thing at once.
Should I get yago2s owl file? or is there any ways to see yago ttl files like dbpedia owl??
Thanks in advance.
The error message when I tried to open yagoTypes.ttl file is
java.lang.reflect.InvocationTargetException

and this same error occurs when I concatenate yagoTypes.ttl and yagoFacts.ttl using cat command, and try to open this concatenated file..
Where to get the data
If you got the data from YAGO2s Downloads, it says right at the beginning of the page:
You can download the entire YAGO2s ontology in one piece. (Extracted
from 2012-12-01 version of Wikipedia.)
Download YAGO2s ontology in
.ttl format! (2.2 Gb compressed, 18.5 Gb uncompressed)
That sounds like what you want. If you just want to see the class hierarchy, though, then you might want the yagoTaxonomy files:
yagoTaxonomy The entire YAGO taxonomy. These are all rdfs:subClassOf facts derived from Wikipedia and from WordNet.
The format of the data
OWL is a ontology language with an abstract structure that can be serialized in a number of different ways including OWL/XML, the OWL Functional Syntax, the Manchester Syntax, and encoded as RDF. Now, RDF is also an abstract format, and can be serialized in a number of ways, including N-Triples, N3, Turtle (ttl), and RDF/XML. Most .owl files that you find are actually RDF/XML files that are serializations of the RDF encoding of an OWL ontology. That's probably what your .owl file is. The .ttl files you're seeing are the Turtle serialization of the RDF encoding of an OWL ontology. Standard RDF processing tools should be able to process it.
I'm using the OWL API, and I have an ontology. I'm trying to import another ontology the way we do in protege, i.e. select the OWL File locally and then import it. Is this possible with the OWL API
I'm using the import declaration,
OWLImportsDeclaration importDeclaraton = ontology.getFactory().getOWLImportsDeclaration(IRI.create("/home/noor/Dropbox/TaggingCaseStudy/Programs/TextBasedMA/files/ontologies/OBMA2/photo1.owl"));
But I'm getting an error, it is not taking the file locally,
Caused by: java.io.FileNotFoundException: http://semanticweb.org/home/noor/Dropbox/TaggingCaseStudy/Programs/TextBasedMA/files/ontologies/OBMA2/photo1.owl
Your IRI is relative, not absolute - it needs to start with file: for a file to be found. Relative IRIs will be resolved against the base IRI at the time of loading, which in your case creates the URL which you can see in the error.
Try making the IRI absolute, or use indirection by using the actual ontology IRI in the import and using an IRIMapper to point at the file.
E.g., if your ontology has an IRI of http://example.com/myontology, use
OWLImportsDeclaration importDeclaraton = ontology.getFactory().getOWLImportsDeclaration(IRI.create("http://example.com/myontology"));
to create the imports declaration, and add an IRIMapper to your OWLOntologyManager for resolving it when loading the ontology:
manager.addIRIMapper(new SimpleIRIMapper(IRI.create("http://example.com/myontology"),
IRI.create("file:///actual/path/to/file.owl"));
Edit: with OWLAPI 4, this looks like:
manager.getIRIMappers().add(new SimpleIRIMapper(IRI.create("http://example.com/myontology"),
IRI.create("file:///actual/path/to/file.owl"));
Javadoc for this can be found on the GitHub page
When I query Google AppEngine's datastore using PHP(through Quercus) and the low-level data-access API for an entity, I get an error that the entity doesn't exist, even though I've put it in the datastore previously.
The specific error is "com.caucho.quercus.QuercusException: com.google.appengine.api.datastore.DatastoreService.get: No entity was found matching the key: Test(value1)"
Here's the relevant code -
<?php
import com.google.appengine.api.datastore.DatastoreService;
import com.google.appengine.api.datastore.DatastoreServiceFactory;
import com.google.appengine.api.datastore.Entity;
import com.google.appengine.api.datastore.EntityNotFoundException;
import com.google.appengine.api.datastore.Key;
import com.google.appengine.api.datastore.KeyFactory;
import com.google.appengine.api.datastore.PreparedQuery;
import com.google.appengine.api.datastore.Query;
$testkey = KeyFactory::createKey("Test", "value1");
$ent = new Entity($testkey);
$ent->setProperty("field1", "value2");
$ent->setProperty("field2", "value3");
$dataService = DatastoreServiceFactory::getDatastoreService();
$dataService->put($ent);
echo "Data entered";
try
{
$ent = $dataService->get($testkey);
echo "Data queried - the results are \n";
echo "Field1 has value ".$ent->getProperty("field1")."\n";
echo "Field2 has value ".$ent->getProperty("field2")."\n";
}
catch(EntityNotFoundException $e)
{
echo("<br/>Entity test not found.");
echo("<br/>Stack Trace is:\n");
echo($e);
}
And here's the detailed stack-trace - link.
This same code runs fine in Java (of course after changing the syntax). I wonder what's wrong.
Thanks.
I have found the solution to my problem. It was caused by missing dependencies and I solved it by using the prepackaged PHP Wordpress application available here.
One thing is to be noted. The package overlooked a minor issue in that all files other than the src/ directory need to be in a war/ directory which stays alongside the src/ directory (this as per appengine conventions as mentioned on its documentation). So I organized the files thus myself, put the above PHP file in the war/ directory, and it's working fine on the appengine.
