I have a proposal to make:
Is it possible that we want to have only one standard (the AggServer version)?
The argument is as follows. Suppose someone is describing a set of dods urls
that correspond to different times. They have no intention of running an
AggServer, so they confine themselves to the InvCatalog dtd. Wouldn't we be
better off if they had described the collection in the AggServer format, so that
we would then be able to detect that aggregation is the appropriate thing to do
with the collection, and to describe/index/present it to the user accordingly.
Or, if the software does not aggregate, just present the collection, nothing
lost relative to the InvCatalog description.
Here are some possible problems:
I am more or less ready to start thinking about catalog version 0.7. If I understand what you are thinking, you want to provide the same functionality as dodsdir ? Can you give specifics of that?
I tend to agree with Benno on this, though the one standard may end up being slightly different than the current AggServer version. My concern is that the current InvCatalog description isn't extensive enough to be much more than a simple list which in the long run isn't sufficient to represent a true catalog. I realize that work is underway to develop queriable catalogs, if possible that effort should try to merge the existing Aggregation descriptions into those catalogs since in some sense there are clear similarities with building multi-dimensional aggregations of simpler types and traversing organizational hierarchies represented in catalogs to uniquely identify data granules of interest.
