Types of Values

[GaBriella Branson]

Hi - I am interested in having the list of values available to a user be more specific than simply "Asset". This is edg:supercededBy on a Business Application and I only want my user to have to select from other Business Applications. Is there a way to do that without deactivating edg:supercededBy and re-defining with a property of my own name in my own property shape for the same sh:path?

Additionally I have a request from a user regarding Business Function and Business Activity. Is it possible after a Business Function is selected (edg:supportsBusinessFunction) to then have the list of available Business Activities (edg:supportsBusinessActivity) be limited to those related to the Function? 

Thank you in advance.

It sounds like you want to narrow down the sh:class constraint for edg:supercededBy at instances of the class edg:BusinessApplication. Doing this in subclasses in generally possible in SHACL and will be understood by TopBraid.

Try adding a new property shape for the same property (sh:path) at Business Application. The resulting source code would look something like this:

edg:BusinessApplication

    sh:property edg:BusinessApplication-supercededBy .

edg:BusinessApplication-supercededBy

    a sh:PropertyShape ;

    sh:path edg:supercededBy ;

    sh:class edg:BusinessApplication ;

.

Disclaimer: I have not tried that out.

Additionally I have a request from a user regarding Business Function and Business Activity. Is it possible after a Business Function is selected (edg:supportsBusinessFunction) to then have the list of available Business Activities (edg:supportsBusinessActivity) be limited to those related to the Function?

This would be much harder because the valid values would have to be the results of something like a SPARQL query and we don't have such an input widget. It is further complicated by the fact that users may change one value or the other while the form is in edit mode, and the UI would dynamically have to switch its allowed values.

So I don't see a built-in solution for that. It is always possible to develop customizations though for special tasks like that.
