Wrong rdfs namespace in cwltool --print-rdf

[stain]

Expected Behavior

cwltool --print-rdf should use conventional valid namespaces where they exist.

Actual Behavior

Wrong prefix for the rdfs namespace, seems to be caused by <rdfs:comment> being interpreted as an URI instead of a qname mapped to the rdfs namespace http://www.w3.org/2000/01/rdf-schema#

@prefix ns1: <rdfs:> .

Your Environment

• cwltool version: 1.0.20170525215327

Could it be because Process.yml and Workflow.yml schemas uses:

- name: SchemaBase
  type: record
  abstract: true
  fields:
    - name: label
      type:
        - "null"
        - string
      jsonldPredicate: "rdfs:label"
      doc: "A short, human-readable label of this object."

yet does not declare rdfs as a namespace?

$namespaces:
  cwl: "https://w3id.org/cwl/cwl#"
  sld: "https://w3id.org/cwl/salad#"

I think that might be it.

Solved by common-workflow-language/common-workflow-language#461 hopefully

@MarkRobbo Yes, I'll make the PR to update the git sub-tree next

[mr-c]

@MarkRobbo I made a new release of cwltool: v1.0.20170622090721 -- please re-open if that doesn't work for you!

[MarkRobbo]

@mr-c Thanks a lot!

Although the namespace is now present, so still is the incorrect one under "ns1" and that is the one being used.

@MarkRobbo Ah, I thought you had tested the other fix :-P

[mr-c]

FYI: rdfs:comment occurs in the jsonldPredicate.id field of DocType of the schema_salad metaschema.yml and likewise for the RecordField in metaschema_base.yml:

The jsonldPredicate.id field is defined as

The predicate URI that this field corresponds to. Corresponds to JSON-LD @id directive

Does this information get us closer to a fix?
