Subject: Re: Recurring Activities

If I understood correctly then it could be modeled by having a single activity that uses and produces the documents,
which are then linked with the "wasDerivedFrom" relationship to their sources:
:aNightlyProcess2015-05-21 a prov:Activity ;
         prov:used :someConfiguration, :doc1, :doc2 ;
         prov:startedAtTime "2015-05-21T02:16:03"^^xsd:dateTime ;
         prov:endedAtTime  "2015-05-21T02:17:20"^^xsd:dateTime ;
         prov:qualifiedAssociation [
                 a prov:Association ;
                 prov:agent :aPieceOfSoftware ;
                 prov:hadPlan :aProcessPlan
         ] .

:aProcessPlan a prov:Plan ;
         rdfs:label "Some general description of what the nightly process looks like".

:record1 a prov:Entity, ex:MetadataRecord ;
         rdfs:label "this is a record created by the nightly process finishing on May 21st"@en ;
         prov:wasGeneratedBy :aNightlyProcess2015-05-21 ;
         prov:wasDerivedFrom :doc1;
         prov:generatedAtTime "2015-05-21T02:16:58"^^xsd:date .

  :record2 a prov:Entity, ex:MetadataRecord ;
         rdfs:label "this is another record created by the nightly process finishing on May 21st"@en ;
         prov:wasGeneratedBy :aNightlyProcess2015-05-21 ;
         prov:wasDerivedFrom :doc2;
         prov:generatedAtTime "2015-05-21T02:17:19"^^xsd:date .
(Apologies for possible syntax errors on the rdf, I haven't validated it).
Would this work? If you want to be more restrictive, you may use the "prov:hadPrimarySource" relationship.

OK, thanks for the feedback. Essentially it's one process that takes one document at the time and creates a metadata record from it. The point is that I couldn't find a way to relate the input document to the created metadata if I have only one process/activity for all documents. Do you have an idea how to express that with only one activity?

Best,

Lars
