Dear all,

FYI, we have just requested our transition to CR. Thanks for your hard work.

The CR documents are now frozen.

We have up to December 4th (noon GMT) to stage the note-track documents.
We will then send a publication request for all our documents.

We have up to December 6th, to complete the implementation 
report/questionnaire/test case
repository.

Kind regards,
Luc

Philippe, Ralph,

The Provenance Working Group requests transition to CR status for four specifications on the Provenance Interchange Specification:

a. PROV-DM: The PROV Data Model
http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/CR-prov-dm-20121211/Overview.html

b. PROV-N: The Provenance Notation
http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/CR-prov-n-20121211/Overview.html

c. PROV-O: The PROV Ontology
http://dvcs.w3.org/hg/prov/raw-file/default/ontology/releases/CR-prov-o-20121211/Overview.html

d. Constraints of the Provenance Data Model
http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/CR-prov-constraints-20121211/Overview.html

The documents are ready for publication.  We can schedule publication at any time depending on when the Directors call is scheduled; we currently planfor the 11th of December, 2012.

(1) Document title, URIs, Abstract and Status

a. PROV-DM: The PROV Data Model

URI:http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/CR-prov-dm-20121211/Overview.html

Abstract:
Provenance is information about entities, activities, and people involved in producing a piece of data or thing, which can be used to form assessmentsabout its quality, reliability or trustworthiness. PROV-DM is the conceptual data model that forms a basis for the W3C provenance (PROV) family of specifications. PROV-DM distinguishes core structures, forming the essence ofprovenance information, from extended structures catering for more specific uses of provenance. PROV-DM is organized in six components, respectively dealing with: (1) entities and activities, and the time at which they were created, used, or ended; (2) derivations of entities from entities; (3) agents bearing responsibility for entities that were generated and activities that happened; (4) a notion of bundle, a mechanism to support provenance ofprovenance; (5) properties to link entities that refer to the same thing; and, (6) collections forming a logical structure for its members.

This document introduces the provenance concepts found in PROV and defines PROV-DM types and relations. The PROV data model is domain-agnostic, but isequipped with extensibility points allowing domain-specific information tobe included.

Two further documents complete the specification of PROV-DM. First, a companion document specifies the set of constraints that provenance should follow. Second, a separate document describes a provenance notation for expressing instances of provenance for human consumption; this notation is used in examples in this document.

The PROV Document Overview describes the overall state of PROV, and should be read before other PROV documents.

b. PROV-N: The Provenance Notation

URI:http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/CR-prov-n-20121211/Overview.html

Abstract:
Provenance is information about entities, activities, and people involved in producing a piece of data or thing, which can be used to form assessmentsabout its quality, reliability or trustworthiness. PROV-DM is the conceptual data model that forms a basis for the W3C provenance (PROV) family of specifications. PROV-DM distinguishes core structures, forming the essence ofprovenance information, from extended structures catering for more specific uses of provenance. PROV-DM is organized in six components, respectively dealing with: (1) entities and activities, and the time at which they were created, used, or ended; (2) derivations of entities from entities; (3) agents bearing responsibility for entities that were generated and activities that happened; (4) a notion of bundle, a mechanism to support provenance ofprovenance; and, (5) properties to link entities that refer to the same thing; (6) collections forming a logical structure for its members.

To provide examples of the PROV data model, the PROV notation (PROV-N) is introduced: aimed at human consumption, PROV-N allows serializations of PROVinstances to be created in a compact manner. PROV-N facilitates the mapping of the PROV data model to concrete syntax, and is used as the basis for aformal semantics of PROV. The purpose of this document is to define the PROV-N notation.

The PROV Document Overview describes the overall state of PROV, and should be read before other PROV documents.

c. PROV-O: The Provenance Ontology

URI:http://dvcs.w3.org/hg/prov/raw-file/default/ontology/releases/CR-prov-o-20121211/Overview.html

Abstract:
The PROV Ontology (PROV-O) expresses the PROV Data Model using the OWL2 WebOntology Language (OWL2). It provides a set of classes, properties, and restrictions that can be used to represent and interchange provenance information generated in different systems and under different contexts. It can also be specialized to create new classes and properties to model provenance information for different applications and domains.

The namespace for all PROV-O terms ishttp://www.w3.org/ns/prov#.

The OWL encoding of the PROV Ontology is available [herehttp://www.w3.org/ns/prov-o.owl].

The PROV Document Overview describes the overall state of PROV, and should be read before other PROV documents.

d. Constraints of the Provenance Data Model

URI:http://dvcs.w3.org/hg/prov/raw-file/default/model/releases/CR-prov-constraints-20121211/Overview.html

Abstract:
Provenance is information about entities, activities, and people involved in producing a piece of data or thing, which can be used to form assessmentsabout its quality, reliability or trustworthiness. PROV-DM is the conceptual data model that forms a basis for the W3C provenance (PROV) family of specifications.

This document defines a subset of PROV instances called valid PROV instances, by analogy with notions of validity for other Web standards. The intent of validation is ensure that a PROV instance represents a consistent history of objects and their interactions that is safe to use for the purpose of logical reasoning and other kinds of analysis. Valid PROV instances satisfycertain definitions, inferences, and constraints. These definitions, inferences, and constraints provide a measure of consistency checking for provenance and reasoning over provenance. They can also be used to normalize PROVinstances to forms that can easily be compared in order to determine whether two PROV instances are equivalent. Validity and equivalence are also defined for PROV bundles (that is, named instances) and documents (that is, a toplevel instance together with zero or more bundles).

The PROV Document Overview describes the overall state of PROV, and should be read before other PROV documents.

(2)  Record of the decision to request the transition:

See minutes of November 9, 2012:http://www.w3.org/2011/prov/meeting/2012-11-09#resolution_5

(3) Record of Changes

The separate section of each document records the noteworthy changes; see the pointers listed above. All Last Comment review comments have been addressed, also as noted above.

(4)   Evidence that the document satisfies group's requirements:

There was no specific use case and requirement document produced by this working group. Instead, the main input documents for the group were the outcome of the Provenance Incubator group:

- Final Report in particular Provenance in the Web Architecture and the Provenance Concepts in the recommendations section.
http://www.w3.org/2005/Incubator/prov/XGR-prov-20101214/#Provenance_in_Web_Architecture
http://www.w3.org/2005/Incubator/prov/XGR-prov-20101214/#Recommendations
- Provenance Vocabulary Mappings
http://www.w3.org/2005/Incubator/prov/wiki/Provenance_Vocabulary_Mappings

these were the starting points for the technical design. More specifically,the Group's charter refers to "see Section 8.1.4 of the Incubator Group report" explicitly and says: "the Incubator Group has identified a set of concepts that will constitute the core of PIL".

http://www.w3.org/2005/Incubator/prov/XGR-prov-20101214/#Proposed_Charter_for_a_Provenance_Interchange_Working_Group

All those concepts were implemented, except for participation and control that are now prov:Assocation.

(5) Evidence that the document has received wide review and that issues have  been formally addressed:

See the list of public comments at:
http://lists.w3.org/Archives/Public/public-prov-comments/

See also last call comment review dispositions noted above with each document.

A review was requested specifically from the following groups: Semantic WebCoordination Group, RDFa Working Group, RDF Working Group, MultilingualWeb-LT Working Group, Oil and Gas Business Group, DCMI Metadata Provenance Task Group and the Internationalization Activity.

- The RDFa WG will include PROV in their initial context, and the ways of using RDFa for the encoding of Provenance discover (subject of a separate note) has also been discussed.

- The RDF working group approved our approach (eg, on the usage of bundles)and will use provenance examples in their specification (seehttp://lists.w3.org/Archives/Public/public-rdf-wg/2012Oct/0208.html).

- The Internationalization Activity was notified and asked for review, but we have not received a response although we were listed on the Activity's review radar
  http://lists.w3.org/Archives/Public/public-i18n-core/2012JulSep/0081.html
  http://www.w3.org/International/wiki/Review_radar

- We have had close collaboration with DCMI creating a note on mappings of Dublin Core to the PROV. This will be published alongside the final Recommendations of PROV

- The Oil and Gas Business Group does not exist any more; however, while itstill existed, there were several informal discussions with members of that BG.

(6) Objections:

There were no formal objections.

(7) Features marked as "at risk":

No features are marked as "at risk".

(8) Patent disclosures:

No patent disclosures for these documents at the moment

(9)  Implementation information:

The working group intends to  issue a call for implementations. The detailsof the exit criteria (including some explanations on the details) are documented at:
http://www.w3.org/2011/prov/wiki/ProvCRExitCriteria

A questionnaire has been created to help the submission of implementations:
https://docs.google.com/spreadsheet/viewform?pli=1&formkey=dGM4cXZYMk0xaFBDT2VyRV92YkY5WkE6MQ#gid=0

Prov-constraints test cases are also available at
http://dvcs.w3.org/hg/prov/raw-file/default/testcases/process.html

The list of test cases for constraints will grow in the coming weeks to provide a complete coverage.

Some information on ongoing implementations is at:
http://dvcs.w3.org/hg/prov/raw-file/default/reports/prov-implementations.html

This will be updated as we receive further information on implementations.

We suggest that the CR period last until January 31, 2013.

(10) Misc

There is also an ongoing media type registration for PROV-N:
