Hi everyone 
I’m amazed how swiftly I can create resource templates (loving the RDF-triple thing!).
However, in some cases I’d like to focus the choices for related “data type = item” to a specific resource template.
For example, I have “has related agent of item” - which I limit to “Data types = Item”, but I /know/ I prefer Items of class “Agent”.
Is that possible?
Thank you very much in advance 
I can use the “select item” feature.
Is it possible to predefine the “Filter search” options in the resource template property?
Like: “Filter by class = Agent”?
That would be amazing!
Grateful for any hints
You might try the DataTypeClass module, if I understand you correctly, it does what you want…
Also looking at AdvanceResourceTemplate may help. I have no knowledge of the current capabilities of this great module.

Hi,
I would avoid DataTypeClass which breaks some core functionality as I found out the hard way (see DataTypeClass module doesn't work with InverseProperties (and possibly elsewhere too...)).
Instead I am using AdvanceResourceTemplate to fake it by setting “Filter linked resources with a query” to only show the required Class in the item search sidebar that pops up.
John.
Yes, if the filtering works in AdvanceResourceTemplate, I would certainly encourage to this instead of DataTypeClass.

Thank you both for your suggestions and input!
I’ll try the AdvanceResourceTemplate, and see how it goes
