This works for me, but the ui:label may return different things
depending on from where you run the query. Safer would be to compare URIs:
FILTER (?type =
<http://evn.topbraidlive.org/evnprojects#Taxonomy>)
or (better):
SELECT ?vocabName
WHERE {
GRAPH <urn:x-evn-master:geo>{
<urn:x-evn-master:geo>rdfs:label ?vocabName .
<urn:x-evn-master:geo>rdf:type
<http://evn.topbraidlive.org/evnprojects#Taxonomy>
}
}
To walk through all (when executing on a server where you are logged in
with suitable privileges):
SELECT ?projectGraph
WHERE {
() <http://topbraid.org/teamwork#readableGraphsUnderTeamControl>
(?projectGraph ?teamGraph) .
GRAPH ?projectGraph {
?projectGraph a
<http://evn.topbraidlive.org/evnprojects#Taxonomy> .
}
}

Irene, the SPARQL that you gave works fine and returns all Taxonomies,
Ontologies & Reference Data sets.
*We have another requirement to write a SPARQL for fetching Taxonomies
only but not others(Ontologies, Reference Datasets,.. )*. For that,
inspired from a SPARQL(given below), which is to fetch a specific
Vocabulary's name and it's type (rdf:type) based on Graph URI, I tried
adding one new line(?projectGraph rdf:type ?type .) to the SPARQL that
you gave above for getting Vocabularies type also. But that returns
zero results. Could you please help us here?
_*SPARQL to get specific Vocabulary's name and it's type(rdf:type)*_
SELECT ?vocabName ?type
WHERE {
GRAPH <urn:x-evn-master:geo>{
<urn:x-evn-master:geo>rdfs:label ?vocabName .
*<urn:x-evn-master:geo>rdf:type ?type .*
} .
FILTER
(ui:label(?type)="http://evn.topbraidlive.org/evnprojects#Taxonomy";)
}
_*RESULT
*_
_*SPARQL to get all vocabularies(Taxonomies, Ontologies, etc..) Grpah
, name and type*_
SELECT ?projectGraph ?name ?type
WHERE {
rdf:nil teamwork:graphsUnderTeamControl ( ?projectGraph ?teamGraph ) .
BIND (teamwork:projectLabel(?projectGraph) AS ?name) .
*?projectGraph rdf:type ?type .*
}
ORDER BY (?name)
Thanks,

Most of the services and their definitions are listed on the
Available Web Services page.
Even if the service you need is not there, it is a good resource
for figuring out how to create a service you need. “Teamwork”
services would be particularly useful for the kind of thing you
want to accomplish.
For example, taking an inspiration from
teamwork:UsagesOfSoftwareSystem (spin:SelectTemplate) or
teamwork:GraphsOfGivenTypeUnderTeamworkControl
(spin:SelectTemplate), your service could be defined as follows:
SELECT ?projectGraph ?name
WHERE {
rdf:nil teamwork:graphsUnderTeamControl ( ?projectGraph ?teamGraph ) .
BIND (teamwork:projectLabel(?projectGraph) AS ?name) .
}
ORDER BY (?name)
It would not need any input arguments.

Hello,
We want to display an HTML page with Metadata(Name, Graph
URI/URN, etc... ) of all available Vocabularies in an EVN
application. It is basically to list all the vocabularies
available in an EVN instance. Is there any SPARQL/REST service
available to achieve this?
Thanks,
sanjeev
