Steve; There are probably lots of different ways to do these. I'll
give some possibilities below that may need adjusting depending on the
details of you ontology:
<Case #1: From the query above, we want to also restrict the tools to
prices under $5000.>
Use FILTER, e.g.:
?tool :price ?price .
FILTER (?price < 5000)
<Case #2: From the query above, we wish to do a "UNION" or an "OR"
where we can get all the direct children of the tools (in addition to
the parent, which the above clause does) selected.>
For this, you can just add the triple pattern:
?child rdfs:subClassOf ?tool
<Case #3: From the query above, we want to select multiple different
properties, so instead of just the ?givenClass rdfs:label "integer
programming", we would want something like ?givenClass rdfs:label
"integer programming" OR ?givenClass rdfs:label "simple additive
method", so that we could in one dataset get tools and their parents
that implement either of these two methods.>
Something like the below should work
SELECT *
WHERE {
{ ?givenClass rdfs:label "integer programming"^^xsd:string .
}
UNION
{ ?givenClass rdfs:label "simple additive method"^^xsd:string .
}
?givenClass rdfs:subClassOf ?parentClass .
?tool :implements ?parentClass .
?tool rdfs:label ?label .
}
