[Mulgara-dev] simple app for functional groupings

[William Mills]

I have a relatively simple app I want to play with in Mulgara, which is doing functional groupings of machines.  In it I have:

roles:      a named grouping of other roles, machine expressions, and machine names.

machine expressions:     a regexp like string used to define a list of hostnames, i.e. www{1-4,6}.mulgara.org whih identifies 5 hosts.

machine names:                a simple machine name like www1.mulgara.org

What is the best (if there is one)  RDF way to structure this so that I can easily get 

1)    the short definition of a role, i.e. the minimal set of roles, machine expressions, and machine names

2)    the full list of host names contained by a role

3)    for a given host get the list of roles it is a member of.

There are several ways to structure this, and I'm not sure of the pitfalls yet.

Thanks,
