Announcements

      * Mark called our attention to the new volatile disk, now available
        from the farm nodes at JLab. See the [30]FAQ for details.
      * Elliott announced that the Midas elog is now available at the Lab
        for interested parties. Yi has experience using it. See Elliott for
        more information.

PID sub-group report

    Paul mentioned that he has disabled drift chamber dE/dx as a particle
    ID discriminator, at least for now.

    Elliott asked if the high-level particle classes are stable now so he
    can incorporate them into DANA-EVIO. Paul said that more re-arrangement
    was coming; something involving kaons[?]

Resource Management

    Dmitry presented a proposal for managing large files that are currently
    controlled in the calib directory hierarchy and, by analogy, to be
    controlled by the calibration database (CCDB). The proposal is that
    large files, like the magnetic field maps, be managed separately, using
    a simpler "resource management" system. This approach is ubiquitous;
    several major software systems use it. There are several advantages to
    breaking out these files from the CCDB and the attendant loss of CCDB
    features are probably not serious for this class of files. See [33]his
    presentation for details.

CCDB beta release

    Dmitry described the feature set of a new release of the CCDB. Several
    enhancements have been implemented since the [35]alpha release. See
    [36]his presentation for details.
