   Provenance Challenge Wiki 

Provenance is a critical concept in scientific workflows, since it allows scientists to understand the origin of their results, to repeat their experiments, and to validate the processes that were used to derive data products.  During a discussion on provenance
standardization at the International Provenance and Annotation Workshop (IPAW'06, www.ipaw.info), the community decided that it needs to understand the different representations used for provenance, its common aspects, and the reasons for its differences. As a result, the community agreed that a "Provenance Challenge" should be set to compare and understand existing approaches.

+The first challenge (details here and teams' results available from here) commenced 2006-June-19 and concluded in a workshop held on 2006-September-13 in Washington, DC.  There was a total of 17 teams, contributing a diverse range of results.   As part of the discussion at that workshop, it was decided to hold a second challenge, for which the focus would be interoperability between systems.

During a discussion on provenance standardization at the International Provenance and Annotation Workshop (IPAW'06, www.ipaw.info), the community decided that it needs to understand the different representations used for provenance, its common aspects, and the reasons for its differences. As a result, the community agreed that a "Provenance Challenge" should be set to compare and understand existing approaches.

  Provenance Challenge 

The provenance challenge aims to establish a common understanding of the capabilities (and limitations) of available provenance-related technologies.  In particular, once the systems have been compared, we aim to have an understanding of the following.

 The representations that we each use to document details of processes that have occurred (e.g. workflows run)

 The capabilities of each system in answering provenance-related queries

 What each system considers to be within scope of the topic of provenance (regardless of whether the system can yet achieve all problems in that scope)



While we hope that all participating projects can contribute to the above aims, we explicitly do not assume that every system will be best evaluated by the same criteria, or have the same definition of provenance, ideal way to illustrate its potential or scope in terms of which queries are considered relevant.

To help achieve the aims, we define a single example process that forms the basis of the challenge.  Here, we use the term process to denote a series of procedures being performed in a system, each taking some data as input and producing other data as output.  We do not assume that these procedures must use some particular form of technology (EXE files, Web Services etc.) or that the process is explicitly defined in a workflow script, but individual projects will interpret the technologies through which the process is executed.  While based on a real workflow, the procedures in the example process are expected to be implemented as "dummies", i.e. we provide the input, output and intermediate data and the projects use fake procedures that take the right input and produce the right output.  If a project wishes to enact the real process, this is also possible.

In addition to this, we will define a set of core queries that all partipicipants should show how they address, so we can compare systems.  The process and core queries will be decided on collectively by the challenge participants.

Each project participating in the challenge will have its own page on this TWiki where they can inform the rest of their efforts in meeting the challenge.  During the provenance challenge, we expect the participants to upload the following to their page, to then allow comparison.

 Representations of documentation of processes or provenance for the example process

 Extensions to the example process to best illustrate the unique aspects of their system

 Additional queries (beyond the core queries) that illustrate the scope of their system

 Any categorisation of queries that the project considers to have practical value



In addition to the above project pages, the result of the challenge will take the form of the following tables by which direct comparison between systems can be made.

 A matrix of queries vs systems, indicating for each that: (1) the query can be answered by the system, (2) the system cannot answer the query now but considers it relevant, (3) the query is not relevant to the project.



  Example Process

+We propose an example process for creating population-based "brain atlases" from the fMRI Data Center's archive of high resolution anatomical MR data, using a multi-stage I/O intensive pipeline that warps the anatomical features of the brain of multiple subjects into a standard space.  The process is shown below.





It is comprised of procedures, shown as orange ovals, and data items flowing between them, shown as trapeziums.  It can be seen as five stages, where each stage is depicted as a horizontal row of the same procedure in the figure.  The procedures employ the AIR (automated image registration) suite to create an averaged brain from a collection of high resolution anatomical data.  In addition to the data items shown in the figure, there are other inputs to procedures (constant string options): we will make these evident in the workflow in the future.

The inputs to a workflow are a set of new brain images (3.a to 5.a) and a single reference brain image (6.a).  All input images are 3D scans of a brain of varying resolutions, so that different features are evident.  For each image, there is the actual image (.i) and the header/metadata information for that image (.h).  The stages of the workflow do as follows.

 For each new brain image, it is compared to the reference image to determine how the new image should be warped, i.e. the position and shape of the image adjusted, to match the reference brain.  The output of each procedure in the stage is a warp parameter set defining the warp to be done.

 For each warp parameter set, the actual transformation is done by creating a new version of the original new brain image with the configuration defined in the warp parameter set.  The output is a warped image.

 All the warped images are averaged into one single image.

 For each
