Looks like you are missing a period after this triple:
?r owl:onProperty hasBO_Target Also, you need to either specify a qname (myprefix: hasBO_Target) or if you are using default namespace put a column in front of the property (:hasBO_Target) Irene Polikoff From: [email protected] [mailto:[email protected]] On Behalf Of Leonard Jacuzzo Sent: Wednesday, May 18, 2011 12:48 PM To: [email protected] Subject: Re: [topbraid-users] SPARQL help. Thanks Again! I gave this a shot. But TBC tells me that it is not well formed. The message that I got is "lexical error at line 3, column38. Encountered "\n" after "hasBO_Target" . I can't seem to figure out what that means and how to correct it. See query below. Best, LFJ CONSTRUCT { ?r ?p ?o. ?c rdfs:subClassOf ?r .} WHERE {?r owl:onProperty hasBO_Target ?r ?p ?o . ?c rdfs:subClassOf ?r .} On Tue, May 17, 2011 at 6:35 PM, Holger Knublauch <[email protected]> wrote: Yes, to get all restrictions on a given property, try something like ?r owl:onProperty ex:myProperty . BTW, in Irene's example below SPARQL 1.1 offers a short notation using DELETE WHERE, e.g. DELETE WHERE { ?r owl:onProperty ex:myProperty . ?r ?p ?o . ?class rdfs:subClassOf ?r . } would delete all triples matched in the WHERE clause. This requires TopBraid 3.5 or above. Holger On May 18, 2011, at 7:56 AM, Leonard Jacuzzo wrote: Thanks Guys, But I have a ton of anoymous classes. If I run this query, I will have to manually go through each triple to find the ones that I want. How do I target a restriction involving a particular property and not the others? Would I substitute the name of the property for '?Prop' in Irene's solution?

This way you will be able to review all triples that are about to be deleted. Irene From: [email protected] [mailto:[email protected]] On Behalf Of Leonard Jacuzzo Sent: Tuesday, May 17, 2011 1:01 PM To: [email protected] Subject: [topbraid-users] SPARQL help. Hi all, Once again I would like to take advantage of your collective wisdom. I have created an ontology with several hundred classes, which are characterized by relations to restrictions on properties, i.e., anonymous classes. Unfortunately, once I was finished, I discovered that I made a particular error for each class definition. So I need to delete the erroneous triples and replace each with the appropriate value for each. My strategy was to select them all and then delete them all via SPARQL. But I cannot figure out how to write the query as it involves restrictions on properties and anonymous classes. Each class has a subclass relation as follows: rdfs:subClassOf [ a owl:Restriction ; owl:hasValue "0.087"^^xsd:string ; owl:onProperty :hasBO_Target ] Each will have a unique value as well. So how do I find all of these triples? Any help will be greatly appreciated.
