Thanks, Holger,
This might really help. My application is one where we have been providing a
service via the TBL SPARQL endpoint, and we’ve had the clients send SPARQL
queries in which they call various SPIN functions which are the underlying
functions of SPARQLMotion scripts. The scripts have been parsing XML (using
Semantic XML against a known standard that provides the .xsd files), then
invoking SPINMap to transform the data into our own native schema.
Now, we’d like to do the same with JSON, so I have a number of questions:
1. Can I continue to use SPARQLMotion with the swon library?
2. If not, and I migrate to SWP, is it still possible to invoke our services
via the SPARQL endpoint? In other words, are there function calls that can be
embedded within SPARQL queries to the endpoint? The client code is not set up
to directly make web service calls.
Just to give you a feel for the interface we offer, a sample call to our
endpoint currently is:
SELECT ?response WHERE {BIND
(<http://epic/scripts/triplestoreOperations#XMLInsert2>("""<?xml version="1.0"
encoding="UTF-8" standalone="yes"?>…<lots of XML>""") AS ?response)}

Subject: Re: [topbraid-users] Semantic JSON capability in TopBraid?
Hi Steve,
we acknowledge that JSON processing is very important and have just added new
capabilities to 5.5.
I assume you are aware of the SWP SWON namespace, used primarily for generating
JSON from RDF. See
http://uispin.org/swon.html
This includes some basic facilities for parsing JSON too:
http://uispin.org/swon.html#parse
The RDF triples created from JSON may be too verbose for some use cases, so we
have just added something into the ui: namespace itself for 5.5:
http://uispin.org/ui.html#json
The latter approach allows you to selectively walk through a JSON structure
using SPARQL.
All these are SWP-related capabilities because in our experience, JSON
processing is part of some other processing steps, in particular web service
calls.
What would your requirements be? Do you have .json files in your workspace that
you want to open similar to Semantic XML?
Regards,
Holger
PS: If you have any control over the JSON that is used, obviously JSON-LD would
be the ideal solution for RDF interoperability. Custom @contexts give you quite
some flexibility.

Hi,
With the increasing appearance of JSON as an exchange encoding, I
was hoping TopQuadrant would release a “Semantic JSON” capability, analogous to
the Semantic XML capability you already offer. I have been working on
recreating this on my own, but am realizing it is not as easy as I had hoped.
Is this being considered? As a fall-back, I tried using open source tools to
convert my JSON into XML and then use your Semantic XML. I was not successful.
