Thanks Pat, for the suggestion.
By following the documentation given in the link
http://uispin.org/swon.html , we are able to implement our own
REST services, which can return the JSON output type in a desired
structure.
But We are facing an issue with the service
*skostemplate:RootConcepts *and the*SPARQL *associated with it*.
*This service/SPARQL returns the expected results(root concepts)
with the EVN's example vocabularies like Geography Vocabulary,
IPTC News Codes. But the same service/SPARQL returns the empty
result set when tried with our Vocabularies.
At the same time, the *skostemplate:BroaderConcepts
(spin:SelectTemplate) *service and the SPARQL associated
with**returns the expected results**with our Vocabularies also.
So I just want to check that, is there any protocol/standard need
to be followed while creating the vocabularies? So that the
available REST services/SPARQLs return expected results for all
the vocabularies.

*Thanks,

Sanjeev,
The swa:GetLabel call allows you to return a user friendly
label for a specific property. This is listed under the 'SWA
SPIN Modules' heading on the Available Web Services page.
Once you have the result from the DESCRIBE servlet, you could
build a URI and make a call like this to get the user
friendly label:
http://localhost:8083/tbl/template?_template=http%3A%2F%2Ftopbraid.org%2Fswa%23GetLabel&resource=http://topquadrant.com/ns/examples/geography%23areaKM
<http://localhost:8083/tbl/template?_template=http%3A%2F%2Ftopbraid.org%2Fswa%23GetLabel&resource=http://topquadrant.com/ns/examples/geography%23areaKM>
http://localhost:8083/tbl/template?_template=http%3A%2F%2Ftopbraid.org%2Fswa%23GetLabel&resource=http%3A%2F%2Fwww.w3.org%2F2003%2F01%2Fgeo%2Fwgs84_pos%23lat
<http://localhost:8083/tbl/template?_template=http%3A%2F%2Ftopbraid.org%2Fswa%23GetLabel&resource=http%3A%2F%2Fwww.w3.org%2F2003%2F01%2Fgeo%2Fwgs84_pos%23lat>
With that being said, you also have full capabilities to
write your own web services to return data in exactly the
format you'd like. Instead of using the DESCRIBE servlet, you
could create a reusable SPIN template with a SPARQL query
like this:
SELECT * WHERE {
GRAPH <urn:x-evn-master:geo> {
<http://topquadrant.com/ns/examples/geography#Japan
<http://topquadrant.com/ns/examples/geography#Japan>> ?p ?o .
BIND (ui:label(?p) AS ?label)
}
}
This would return the results for Japan in a format with the
more user-friendly predicate labels already associated with
the specific values. This could be extended to, instead of
having Japan hardcoded in - allow for a resource parameter to
be passed in at runtime. More information on the SPIN
template service can be found in the help under *TopBraid
Composer *--> *TopBraid Live Integration *--> *SPIN Template
Service*.

Pat,
Regarding the DESCRIBE servlet, the service
http://localhost:8083/tbl/describe?_resource=http://topquadrant.com/ns/examples/geography%23Japan&_format=application%2Frdf%2Bxml&_base=urn:x-evn-master:geo
<http://localhost:8083/tbl/describe?_resource=http://topquadrant.com/ns/examples/geography%23Japan&_format=application%2Frdf%2Bxml&_base=urn:x-evn-master:geo>
returns some property names with prefixes (as shown
below). So it is bit difficult to remove those prefixes
and then to display those property names to the end users .
I just want to check that is there a way to get the
property names with out the prefixes(as displayed in the
screen shot of EVN UI below).

Sanjeev,
This can be done with a combination of a few of our
different built in services. All of our services
allow for a _base parameter, which denotes the base
graph upon which to run the service against - so they
can be run generically against any graph we choose.
skostemplate:RootConcepts will return all of the root
concepts for you. For 5.3 - we've added
skosTemplate:TopConcepts - which will return the same
result for Taxonomies in a slightly more performant
manner.
skostemplate:NarrowerConcepts will return all of the
children of a specific concept for you.
Information on the skostemplate services can be found
here (with TBCME running):
http://localhost:8083/tbl/swp?_viewClass=servicedoc:Index
<http://localhost:8083/tbl/swp?_viewClass=servicedoc:Index>
The ones we're interested in are under the 'TopBraid
SKOS Templates' heading.
the DESCRIBE servlet can be used to return all of the
information about a specific concept - so we can use
this to get all of the predicates/objects for a
specific item. More information on this can be found
in TBCME Help under TopBraid Composer -> TopBraid
Live Integration -> The DESCRIBE servlet.
Ultimately, you could do something like this:
1) get all roots
2) get all info about a root
3) get all children of the root
4) get all info about each child and go back to 3
1 would be achieved with skostemplate:RootConcepts, 3
would be achieved with skostemplate:NarrowerConcepts,
and 2 and 4 would be achieved with the DESCRIBE
servlet. If you want to user a smaller number of
services, you also have the option of writing your own.
Hope it helps,
Pat

Hi,
There is a requirement to generate a HTML page as
shown below for a given vocabulary. So I just
want check that, are there any SPARQL / REST
services to traverse through all the
Subjects/Nodes with predicates and objects of a
given vocabulary.
In specific, we are looking for SPARQL/REST
service(s) to achieve the following,
1) One SPARQL/REST service to get all
Top-level/Root Subjects with all of their
Predicates and Objects
2) One SPARQL/REST service to get Descendant
Subjects with all of their Predicates and Objects
of a given parent.
We want to make this implementation as much as
generic. I means by passing the name/Graph URI of
a given vocabulary, the same SPARQL/REST services
should be able to return the respective
vocabulary's desired data.
Thanks,
*_EVN Vocabulary
