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
