Re: Process cases and conditions

I like the specialization of the stream to case of stream. That way a stream can also have the same process data without being a case (so, it is the design case). I have no idea what that is supposed to mean, really. The specialization of the stream is because you have two modes of operation/proces...

Re: Process cases and conditions

@Onno - I prepared a diagram to illustrate the relation between process cases/modes of operation and stream data: mode-of-operation.png Pump C2 must be capable of handling, one at a time, streams 1A and 1B. Sometimes this is not possible and then two pumps may be required, with all the consequences ...

Re: Process cases and conditions

@Onno - What would be the alternative for your DESIGN case?

Minimum, maximum, normal xxxx are classes of indirect property.

Re: Process cases and conditions

@Onno, The term "class of state" does it mean class_of_status? assuming it does. No state is not status. Status of an individual, such as "defective", is a state, but any information you represent with a template for individual is a state of that individual (state of being connected, of having a par...

Re: Nullifying Values in Part7/8

@Andy - Why would you want to specify what isn't there?
But if you insist, why don't you leave the value blank, e.g.:

<tpl:valPropertyValue rdf:datatype="&xsd;float"></tpl:valPropertyValue>

In the triple format that results in: ""^^http://www.w3.org/2001/XMLSchema#float

Re: Process cases and conditions

@Onno - The RDL is incorrect here in stating (typically) that an indirect property is a subclass of a SinglePropertyDimension. In this case even OPERATING TEMPERATURE is incorrect. Its definition states: A temperature under which an object is supposed to work. That clearly is an indirect property an...

Re: Replacing old with new information in a façade

@Keith - Thanks for your contribution! In general I agree with what you wrote. I have a few remarks: a) Connections - these typically will have to be handled in the context of the 3D model or 2D representation in which they occur. In a 3D model you may concern yourself with direct connections at Po...

Replacing old with new information in a façade

When we load a template instance in a façade, the façade software shall be capable of detecting whether or not there is an older version of that template that needs to be deprecated This topic is to start an exchange of views on the following question: HOW? Some thoughts: 1) it depends on the templ...

Re: Hiding the (class_of)temporal part in template signature

@Keith - Ahh, that's it. Well, that unlocks a wider topic: when we load template instances in our store, what shall be done then? Important issue is the question how the system can find out whether the new information does or does not replace older information, and if so, which template then must be...
