Hello Scott, I'll have a look. partial choices: in attached ontology when I wanted to add existing individuals of WallSegment as parts for my Wall individuals. if you want to reproduce: 1. go to Wall1 of Class Wall 2. at hasPart_directly widget do "add existing"' (there are already 2 individuals there) 3. the list on the right has no scroll bar only after you select again the already selected owl:Thing (I added some dummy individuals to make the problem apperent otherwise the list was too short...) ps this is the same ontology of the inference problem....you get the error when you run Inferences and then try to look at Wall1 again...(anyway I study your examples too)

The first syntax error is to encapsulate the AS statement with parentheses: SELECT (SUM(?cost) AS ?totalCost) The second is to use the variable name ?arg1 - i.e. the "?" is missing. When a function is created, it exists in your ontology as a URI. Therefore you need to use a qname or full URI to name the function, i.e.: :sumFunction() or <http://myStuff.org/funct#sumFunction> <http://myStuff.org/funct#sumFunction> () Give that a try. -- Scott On Mar 17, 8:11 am, Michel Bohms <michel.bo...@gmail.com> <mailto:michel.bo...@gmail.com> wrote: Replying myself after reading the manual :) I now first defined a subclass of sp:Functions called sumFunction.

Feel I am getting closer....thx for getting it to work!

When I do as spin:rule: CONSTRUCT {?this :totalCost ?totalCost } WHERE { LET (?totalCost := sumFunction (?this)). } it seems the box stays red although I defined: a spin:body SELECT SUM(?cost) AS ?totalCost WHERE { ?this :hasPart_transitive ?Part . ?Part :cost ?cost . OPTIONAL { ?part :hasPart_directly ?anotherPart . } . FILTER (!bound(?anotherPart)) . } clearly I am missing the "sumFuction" definition itself but how do I do that ? (assuming SUM is now implemented in the latest beta). (to refresh your memory: the idea was to calculate the cost of the whole by counting all the leaf part's cost via querying over the all transitive parts and then filter out the atomic leafs) thx a lot, Michel This e-mail and its contents are subject to the DISCLAIMER at http://www.tno.nl/disclaimer/email.html This e-mail and its contents are subject to the DISCLAIMER at http://www.tno.nl/disclaimer/email.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TopBraid Composer Users" group.
