clarification on bundle namespace scoping about prov HOT 6 CLOSED

Hi Satra

See https://www.w3.org/TR/prov-n/#component4

Also note you shouldn't use xsd:QName but prov:QUALIFIED_NAME

@lucmoreauhttps://github.com/lucmoreau and @trungdonghttps://github.com/trungdong - quick clarification question here:

in the example below, i feel the id (ex:bundle1) should remain in the another.orghttp://another.org namespace, even though the content is in example.orghttp://example.org. i couldn't find a clear place in the prov-dm document that clarifies scoping rules of prefixes. if you have a pointer that would be great.

document
prefix foo http://example.org/
prefix ex http://another.org/

entity(foo:bundle1, [prov:type="prov:Bundle" %% xsd:QName])
entity(ex:bundle2, [prov:type="prov:Bundle" %% xsd:QName])
bundle ex:bundle2
prefix ex http://another.org/

used(ex:use2; ex:aa1, ex:ee1, -)
activity(ex:aa1, -, -)
entity(ex:ee1)

endBundle
bundle ex:bundle1
prefix ex http://example.org/

used(ex:use1; ex:a1, ex:e1, -)
activity(ex:a1, -, -)
entity(ex:e1)

endBundle
endDocument

thanks @lucmoreau - this is the last bit to fix given the test set.

@trungdong - the qname thing is happening within the provn serialization in the prov library. could you please take a look at that? i'm simply reading the json file and calling get_provn on the object.

@satra, you may ran the above example with old code. The current version of PROV should give:
entity(ex:e1, [prov:type='prov:Bundle']) instead.

from prov.

@trungdong - this is with the current version.

In [2]: g = pm.ProvDocument.deserialize('/software/nipy-repo/w3c/prov/prov/tests/json/bundle1.json')
INFO:rdflib:RDFLib Version: 4.2.1

In [3]: print(g.get_provn())
document
  prefix ex <http://example.org/>

  entity(ex:bundle2, [prov:type="prov:Bundle" %% xsd:QName])
  entity(ex:bundle1, [prov:type="prov:Bundle" %% xsd:QName])
  bundle ex:bundle1
    prefix ex <http://example.org/>

    used(ex:use1; ex:a1, ex:e1, -)
    activity(ex:a1, -, -)
    entity(ex:e1)
  endBundle
  bundle ex:bundle2
    prefix ex <http://example.org/>

    used(ex:use2; ex:aa1, ex:ee1, -)
    activity(ex:aa1, -, -)
    entity(ex:ee1)
  endBundle

@satra, these are left-over remnants from a long time ago that have escaped my attention.
They all now updated. Thanks.

Is there anything else with this issue? Should we close it?
