Re: [topbraid-users] No inferences

[Scott Henninger]

Michel;  To count a set of values, you'll need to use GROUP BY to group your results by the item you want to aggregate and sum the object values.  Looking at your data I'm guessing you want to sum all of the values from the depc:hasTimePointProperty where the value is found in the depc:TimePointProperty instances.  Given these assumptions, the sub-select will look something like the below: SELECT ?part ((SUM(xsd:float(?eProduction2))) AS ?eProduction1) WHERE {             ?this dcterms:hasPart ?part .             ?part depc:hasComplexProperty ?ProfileProperty2 .             ?ProfileProperty2 depc:hasTimePointProperty ?TimePointProperty1 .             ?TimePointProperty2 depc:e-Production ?eProduction2 .             ?TimePointProperty2 depc:timeStamp ?timeStamp1 . }  GROUP BY ?part See if that give you the results you are looking for.  The general idea is to group by the thing you need to aggregate, then perform the count/sum/etc. on the object with the desired values. -- Scott On 5/15/2014, 3:16 PM, Bohms, H.M.

Inow understand but still see no inferences.   Current query: CONSTRUCT {     ?this depc:hasComplexProperty ?ProfileProperty1 .     ?ProfileProperty1 a depc:ProfileProperty .     ?ProfileProperty1 depc:hasTimePointProperty ?TimePointProperty1 .     ?TimePointProperty1 a depc:TimePointProperty .     ?TimePointProperty1 depc:e-Production ?eProduction1 .     ?TimePointProperty1 depc:timeStamp ?timeStamp1 . } WHERE {     {         SELECT ((SUM(?eProduction2)) AS ?eProduction1)         WHERE {             ?this dcterms:hasPart ?part .             ?part depc:hasComplexProperty ?ProfileProperty2 .             ?ProfileProperty2 depc:hasTimePointProperty ?TimePointProperty1 .             ?TimePointProperty2 depc:e-Production ?eProduction2 .             ?TimePointProperty2 depc:timeStamp ?timeStamp1 .         }     } . }   What I try to do is derived for the Neighbourhood individual a value for its total energy production as sum of the existing energy productions of its parts (for which values are given). (one value for each dateTimeStamp).   Any hint to my thinking error is very welcome! (maybe the path in the construct should be generated differently?)
