Since I am going to need to do this programatically and generate the
sparql query on the fly, it looks like I need to go towards Irene's
suggestion, since the selection of one or more criteria will be done
by a end user on a form. I do not think that Holger's suggestion
would be a good one for a dynamically built grouping, and building the
multiple combination of possibilities of even three items generate 7
unique combinations (and I have many more than 3 items in my
possibilities list). It is a very interesting way to deal with it,
and does help me think of other ways of approaching the problem.
I am unsure about the UNION operator Scott suggests, since I can see
how it applies for the single subject case and would be generate the
URIs I needed, but I do not know if or what the syntax would look like
for the additional properties. Would it be something like:
SELECT *
WHERE {
{ ?ApplicationUri rdfs:label "forestry" .
?subClass rdfs:subClassOf* ?ApplicationUri
}
UNION
{ ?ApplicationUri rdfs:label "drilling" .
?subClass rdfs:subClassOf* ?ApplicationUri
}
UNION
{ ?ApplicationUri rdfs:label "oceans" .
?subClass rdfs:subClassOf* ?ApplicationUri
}
}
I appreciate the help from each of you on this, since as I am learning
sparql. I sometimes still frame it in SQL terms that I am familiar
with, and changing that mindset is sometimes hard. Thank you for your
help.
Steve
