Hi pals,

Julia Weist from Collective Access shared some thoughts with me, and now
I'm sharing them with you. Note: I'm not saying we should use CA for our
catalog, just that Julia gives us some things to think about.

We have some experience with consortium projects here at CA, and those
function similarly to how a cooperative union catalog would.  In those
cases, we've had associations (comprised of several dozen museums) manage
individual back-end systems where they separately enter their data.  Those
back-ends systems, though separate, are identical in terms of metadata and
configuration.  Each system sends data (through scheduled migrations--could
be daily) into a single aggregator system.  That pooled back-end fuels a
single front-end.  We've learned a few lessons with this, and I'll share
those in case they are helpful!

  1. We had to develop special tools which I'll call "metadata quality
    assessment rubrics" which use regular expression (/pattern matching) to
    flag data that was subpar based on the rules of a shared content standard.
    This helps your data look clean and consistent when it's being created from
    so many different cataloguers.

  2. Every difference between systems adds complexity.  In our case this
    wasn't a concern because we designed all the systems to be identical, but
    if you're working with various partners on various platforms it can quickly
    become a ton of crosswalking and custom sub-projects to get one system to
    talk to another.  My advice would be to pick one shared platform and a
    common metadata schema.

  3. The aggregation needs to be have built in rules to handle authority
    reconciliation.  What happens if two people submit data about the same
    person on the same day?  Who's is kept?  Are they merged?  If merged, will
    the data be redundant?  Sometimes this can be entirely handled with a rule
    set, other times a human intelligence is required.

CollectiveAccess could certainly work for this, because as I mentioned
we've done it before so it wouldn't require reinventing the wheel.  But
configuration, build out, partner wrangling and support does take time, so
we'd need funding if you wanted to go that route.

In any case I'm happy to provide an opinion here and there if that helps,
or to talk more seriously about using CA if you want.  In either case
sounds like a great project!
