filtering on a class based target

[sfolsom]

I was looking to define a class target more narrowly based on a particular value of a particular property, and there doesn't seem to be a built in way in SHACL to do this. Then I came across https://www.w3.org/TR/shacl-af/, and I'm exploring sh:filterShape. I'm wondering if the following is valid SHACL.

:EBooksShape a sh:NodeShape ;
  sh:targetClass ex:Publication;
  sh:filterShape [
      sh:property [
        sh:path ex:carrier
        sh:value :Electronic
      ]
    ]

The use case is to define separate targets using the ex:Publication class, one for when the ex:carrier value is :Electronic, and one for when the value is :Print.

@sfolsom you've raised a valid SHACL-related question but this isn't the forum for it. This forum - Issues on this repository - is for the development of the next version of SHACL, as per our Working Group page details, not for community discussion of SHACL problems.

Please could you re-post your question to StackOverflow's [shacl] tag where it will surely be answered.
