Is there an EDG/SHACL equivalent of spin:constructor?

[Tim Smith]

Hi, 

I need to populate the values of some proprieties when an instance is created in EDG.  Some of them require SPARQL functions. 

What is the preferred way to do this in EDG?

Thanks in advance for your help,

Tim

Hi Tim,

This may be just the thing (for 7.1):

(Requires basic JS skills, but if you’re not familiar we can give you starting points, e.g. use graph.update(`INSERT …`) to run a SPARQL UPDATE.)

Thanks Holger!  I'll take a look and refresh my Javascript skills.

The best way to experiment with this (ADS) technology is to open the Script Editor panel and just execute little test scripts. Once you’re familiar and it seems to work, then copy the resulting script into the constructor’s dash:js property.

Good luck, and please ask follow-up questions here (I am currently traveling in Tasmania so my responses may be slower than usual).
