**ASBP working group end of year presentation:**
<https://gforge.nci.nih.gov/frs/download.php/3637/20080227_ASBP_end_of_year.ppt>

-   ABSP WG reviewed its charter and objectives

-   The working group process is reviewed as follows: collect pain
    points from team members -\>solution brainstorm-\>submit preferred
    solution to ARCH/VCDE etc -\> prototype solution demo -\> write
    white paper and submit proposal to ARCH/VCDE

-   Issues, results and conclusions

    1.  ASBP WG presented 4 issues: Model Reuse, XSD Reuse and/or
        generation, Service development Process and Parameter modeling.

    2.  Deliverables: ASBP white papers on GForge and demo service in
        GenePattern caBIG SVN

    3.  Future work:

        -   Finish demo service registration, assessment and impact
            analysis

        -   Tooling integration

        -   Additional Best practices development

-   Questions

    1.  Is parameters requiring a list of features in a regression
        covered?

        -   Discussion of model extension. Proposal focus was on
            process.

    2.  Modeling parameters was addressed, but what about the inputs and
        outputs? In this case the service is reusing a different
        existing model since you can not grab annotated XMIs.

**HTP working group end of year presentation:**
<https://gforge.nci.nih.gov/frs/download.php/3636/2008-02-27-ICR-HTP.ppt>

-   The HTP working group reviewed the charter and process.

-   ICR use cases and requirements were presented as follows:

    -   Data transfer and parsing requirements

    -   'Workflow' requirements

    -   Implementation requirements

-   Several available solutions were discussed - Endpoint references,
    WS-Enumerations, and GridFTP

-   Significant cross-cutting issues reside in VCDE, ARCH and caGrid.

-   Emerging caGrid solutions and directions: The HTP WG came up with a
    number of requirements for an alternative non-grid high performance
    delivery mechanism in order to meet the challenges in caGrid
    transfer.

-   Next steps include prospects, resource development for available
    solutions, and significant issues in data representation and
    description.

-   Questions

    -   Have you done benchmarking with GridFTP?

        -   Referred to the Dicom imaging presentation which applies to
            anything with array or genomic type datasets. There was a
            suggestion to add this data to the HTP wiki.

    -   Which solution would you use when?

        -   GridFTP --

            -   Genotype/phenotype correlations

            -   Moving genotype in a data service at one center

            -   When an application wants a subset of data or each query
                pulls a different submatrix

            -   ok for visualization

        -   caGridTransfer --

            -   If the data is 1M and 500M -- where you want to be able
                to generate manageable to stream but don't want the
                expense of serialization and deserialization.

            -   What is the cut-off where size the data is too big for
                GridTransfer? If you have cluster based usage of data
                (over various sites), or if you have power users doing
                parallel transfer, then GridFTP is the right solution.

    -   Is there a solution to allow pulling data in the background why
        looking at something more specific? Dicomm did this with WS
        enumeration. This is more of an application issue, but the Grid
        allows architecting a solution.

**Workflow working group end of year presentation:**
<https://gforge.nci.nih.gov/frs/download.php/3638/workflow_results_feb27_2008.ppt>

-   The Workflow WG reviewed the charter and process.

-   Results were presented in the following areas and a demo was shown
    to the group.

    -   Authoring tools

    -   Workflow implementation

    -   caGrid services

-   Issues and solutions

    -   The stability of services

    -   Service Specification

    -   Reuse of CDEs does not guarantee the interoperability of
        services in workflows

    -   Reusing workflows

-   Next steps include: work with mentors and the caGrid team, recommend
    new service level meta data items, and engage imaging WS etc.

-   Questions

    -   There were several on color representations in Taverna

    -   Similar CDEs do not guarantee interoperability and this prompted
        discussion. Semantic issues are a matter for VCDE and examples
        should be taken for incorporation in the guide for mentors as
        well as be incorporated in the tooling for a review service. The
        syntactic issues need to be looked at from a schema and naming
        aspect. You would want to take parts of a schema that are the
        same and be able to move it from one point to another in a
        workflow.
