Why not try the following in your CONSTRUCT module:
CONSTRUCT {
publishedBook:IEE_Code_of_Practice_3rd_Edition ?arg1
?newValue .
}
WHERE {
publishedBook:IEE_Code_of_Practice_3rd_Edition ?arg1 ?value
.
BIND (IF(?value = 50), 50, 40) AS ?newValue)
.
}
There's rarely a need for the BranchByAsk module
because SPARQL can take care of the logic. Places I find
BranchByAsk useful is when the script is
choosing from one or more
graphs to load, etc. Things like that - when
manipulating a triples stream
conditionally.

Hi again,
I am struggling to get the sml:BranchByAsk to work . Here is the
scenario...
I wish to update a graph using from an external ui using scripts
called from an external source, which I can do using a standard
importfromworkspace----construct/update rdfprocessingmodule---
export rdf, but before I do this I wanted to make sure that the
property that I am trying to update is valid, ie exists in the
model, so intially i thought (please forgive my naievity once
again) that I could just create another subclass of sm:Functions
assign it an export to remote return module and use an ask query
to determine whether the property variable passed into the script
existed. Unfortunatley ther is no "ask module" only a construct
module under rdf processing. So then I thought ok follow the
example in the tutorial by using a branch by select , but whatever
i do I cannot get it return anything, although the query works
fine using the spaql tab of tbc. Here is as much info as i can
give, the construct statements are just trying to test a sucessufl
outcome but as stated i dont get any results back
Testing this from tbc, when i run the script and user input is
required from the popup for the arg1 i have tried the following
but nothing works, I think I am missing a binding or having to
build an uri
format_TabStop
coreModel:format_TabStop
http://example.com/library/coreModel#format_TabStop1
<http://example.com/library/coreModel#format_TabStop1>
.hope you can help
Regards
John
