This document reports on implementations and usage of the four normative specifications ([PROV-DM], [PROV-N], [PROV-O], [PROV-CONSTRAINTS]) of the PROV Family of Documents [PROV-OVERVIEW]. In particular, it's aim is to demonstrate that the features defined in PROV are implementable and interoperable. Features are defined as: the constructs specified in [PROV-DM] and their realisation in OWL (see [PROV-O]) and in the [PROV-N] syntax; the constraints defined within [PROV-CONSTRAINTS]. Interoperability is defined through both the interchange of provenance information and the coverage of test cases.

This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.

During the Candidate Recommendation period of PROV, implementation experience was reported. This document summarises those experiences. The version at http://www.w3.org/TR/2013/WD-prov-implementations-20130312/ is the version used for purposes of transition to proposed recommendation.

This document was published by the Provenance Working Group as a First Public Working Draft. If you wish to make comments regarding this document, please send them to public-prov-comments@w3.org (subscribe, archives). All comments are welcome.

Publication as a First Public Working Draft does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.

This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. The group does not expect this document to become a W3C Recommendation. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.

Table of Contents

1. Introduction

The goal of PROV is to enable interoperable interchange of provenance on the Web. We take two approaches to documenting the implementation and interoperability of PROV.

  1. For the data model [PROV-DM] and the two working group defined serializations, we document the existence of multiple implementations that support each of the constructs within the data model and that there exists at least two implementations that are reported to exchange these constructs.
  2. We document that the PROV-Constraints specification is implementable by documenting the existence of at least two implementations that report to support all the defined constraints. To evaluate the coverage of implementations, the PROV-Constraints Test Cases are used as a point of reference. There are 280 test cases in total, which map to the the constraints defined by the document.

PROV is useful not only for applications/programs but also for exposing provenance within datasets and as a foundation for other vocabularies. We also document that usage as well.

Implementation evidence was gathered using four surveys.

This report summarizes the results of these surveys.

1.1 Meeting the Exit Criteria

At the start of the Candidate Recommendation phase, the Working Group defined a series of exit criteria. These exit criteria can be summarized as for each feature defined by PROV there are at least two implementations that support the feature and that there exists one interoperability pair that can exchange that feature. Section 3.1 shows that a minimum of 4 implementations both produce and consume all constructs defined in PROV-DM. PROV-O is implemented by over 40 implementations and PROV-N is implemented by 7 implementations.

In terms of implementation pairs, Section 4 enumerates which pairs of implementations report exchanging provenance. Here, we meet the exit criteria in that each feature is exchanged by at least two implementations.

Finally, three validators have implemented all of the constraints defined in PROV-Constraints passing the requisite test cases, thus, passing the exit criteria. The working group recognizes that implementing the PROV-Constraints document requires substantial effort. It is nice to see that three radically different approaches were chosen to implement this specification: SPARQL, Java, Prolog, which speaks to the implementability of this specification.

Although the Provenance Server (#17) and the ProvValidator (#64) are from the same institution (i.e. University of Southampton), it is worth noting that they were built from two independent code bases (one in Python and the other in Java)
