Re: [topbraid-users] breaking a list of tokens up?

Well, as a SPARQL query it (the suggested solution) worked perfectly,

context:
Sample list:
[TRANSDUCER^^xsd:NMTOKEN, PHYSICAL^^xsd:NMTOKEN,
FUNCTION^^xsd:NMTOKEN]
is what ?obj2 in the query below looks like (which is type rdf:List)
SPARQL query (works great):
*SELECT*?o
*WHERE*{
*?arg1* owl:equivalentClass ?obj .
?obj owl:oneOf ?obj2 .
?obj2 (rdf:rest)*/rdf:first ?o .
}
and ?o is then bound to 3 strings: TRANSDUCER, PHYSICAL, and FUNCTION.
If I put the same SPARQL query into a SPIN rule:
*SELECT*?o
*WHERE*{
*?arg1* owl:equivalentClass ?obj .
?obj owl:oneOf ?obj2 .
?obj2 (rdf:rest)*/rdf:first ?o .
}
and bind ?arg1 to the same object that I used in the SPARQL query, I
get just TRANSDUCER as a result.
SPIN functions can only ever return one result, and in your example the
ordering of those values is arbitrary. If you need a function that
produces multiple results, use spin:MagicProperty instead. If you need a
SPIN rule, convert this into a CONSTRUCT query.
On your second question, yes I am sure we have lots of experience
building complex strings out of SPARQL data. But if the logic becomes
really complex, then using something like SWP is often the best choice.
There you can operate on auxiliary result sets, do if-then-else and
loops like in a programming language. You can turn SWP snippets into
SPARQL functions, as described here:

Very confusing. And what I want to do with this list of strings is to
create a formatted string out of their combination. At first I thought
I might be able to use spit:convertSPINRDFtoString in the SPARQL to
create a string of strings and then operate on the new string. That
didn't work because, even though the object I gave it is rdf:List the
function complained that I was trying to convert a non list to a list.
Then I thought I might try ui:concat but since my SPIN function isn't
working it is hard to test this.
Question 1: Does anyone know why my SPARQL doesn't work in the SPIN
function above?
Question 2: Has anyone need to and figured out how to build a
formatted string without some complicated logic?
Thank as usual for any pointers...

Jack; No reason to use spif:split, given that the data is
already in RDF. Something like the following should work:
SELECT ?str
WHERE
{ ...
?s rdf:rest*/rdf:first ?o .
BIND (xsd:string(?o) AS ?str)
}
The rdf:rest*/rdf:first idiom will de-construct the RDF list
into elements.

I have a list of xsd:NMTOKENs that I want to render (using
SWP) in a table or chart. These items are in an
owl:equivalentClass as owl:oneOf items (an enumerated type).
I tried breaking them up with spif:split (oops, not a
string), and spif:foreach but neither worked. Here is an
example list:
[FOO^^xsd:NMTOKEN,
BAR^^xsd:NMTOKEN,
BAZ^^xsd:NMTOKEN]
With other ways of modeling enumerated types (e.g., by
representing FOO as an instance) I can do this, but this
modeling approach was used by someone else.
Is there a way to de-list these items in a SPARQL query?
Thanks,

[topbraid-users] updatable variable within a SWP ui:foreach that isn't the loop counter and depends on result set
I am working on logic that will populate my SWP content based on some
calculations that must take place locally. What I really need is a local
variable that I can update the value of based on its previous value and the
current set of values coming in through the result set. I tried using 'var
foo = ...;' but didn't know how to reference 'foo' inside the '{= ...}
expression. The '?foo' didn't work.
Is there a way to do this? At first I thought I might be able to achieve
this by writing a SPIN rule but even though I can implement that
calculation associated with the variable I cannot update the variable
itself.
For example, lets say I have a ui:foreach as follows:
ui:forEach ui:indexVar=index ui:resultSet={= ?entries }{= spin:nl() }
\\
{= ui:newline() }var curry = {= eddl:boxStartYPosition(?index, curry,
eddl:bcydist(?range)) };\draw (12,{= ?curry })...}
{= ui:newline() }/ui:forEach
where ?range is defined within the SPARQL response in ?entries and ?curry
was originally defined at the outer ui:group using 'let'.
Any ideas/pointers would certainly be appreciated!!! Thanks.

Re: [topbraid-users] Project Upload in TBL with .sdb Files
Bart, I think that message reflects some previous limitations that no longer have relevance. We'll take it up as an issue. Meanwhile, your scenario should work fine. As long as the SDB connector is the same in EVN and TBC-ME (via EVN Config Params), the respective systems will point to the same data on the back-end. -- Scott On Feb 24, 2015, at 5:24 PM, Barton Petersen bart.peter...@gmail.com wrote: I would like to simulate a (production) deploy where the person doing the deployment (potentially off shore) does not have access to TBL-ME and where I don't have direct access to a TBL server.
