Hi,
if I understand your question correctly, your main issue is the ease of
converting from SPIN RDF triples back to an executable SPARQL string?
The easiest way to do that might be to store your queries using sp:text.
Search for sp:text in http://spinrdf.org/sp.html for examples:
[ a sp:Ask ;
sp:text """
# must be at least 18 years old
ASK WHERE {
?this my:age ?age .
FILTER (?age < 18) .
}"""
]
This way, you don't need another SPIN converter and can retrieve the
SPARQL strings with a simple query.
Does this help?

Hi all,
I'm a new user of SPIN. I'm able to convert the SPARQL query into SPIN
syntax. The SPIN query will then be stored in the external triple
storage (Jena TDB, Virtuoso,...) so I can do some analytic later on.
However, it leads to the problem when I'm trying to convert back from
SPIN query to SPARQL. My assumption is that, in order to convert back
SPIN query to SPARQL, I might need to retrieve all the SPIN triples
and save into a jena model. Then, I will be able to convert back to
original SPARQL. My question is, how I can write the SPARQL query to
get back all the SPIN triples from the external triple storage, or is
there any sufficient way to do that?
Thanks a million
