Tennessee,
Did you ever get a reply (besides this one :-)?

Hi guys,
Firstly :
I have "solved" the problem with the bad characters. The problem is
that the NetCDF reader that thredds uses makes use itself of the
"urlPath" specification when coming back with the DDS and DAS. As
such, if use the "=" character (among others) in the urlPath (even if
it's in the path rather than the simple filename), it gets inserted
into the DDS/DAS by the NetCDF reader, which causes errors down the
track in the parser.
I have worked around the problem by having a separate internalService
for each dataset. The "base" section can contain the illegal
characters without polluting the DDS/DAS of files read by the NetCDF
reader. For the moment this is fine, but is less than ideal. I may
return to it after dealing with more pressing issues. In future I will
look at encoding the illegal characters as escaped strings or encoded
in some way, but it's tricky to be sure that you've covered all of the
cases when thinking about those techniques.
Maybe once everything goes XML the problem will simply disappear, and
I can just wait it out :)
Secondly :
I am trying to work out how to structure my data by date. I will have
a number of data sets (NWP Models) which will get updated daily, or
even multiple times per day. Quite quickly I will reach the point
where I will have hundreds of data sets published. Even a week's worth
of data at 2 per day across 3 sources is 42 data sets.
I have two tasks - one would be to automate the updating of the
configuration files so that new data sets get incorporated as they
become available, and the other would be structuring the data pages in
a sensible way for users to access.
I was wondering what practises people might have adopted or found
successful in the past with regards to handling large amounts of data?
Have people typically arranged archive data as aggregations, or linked
to archive catalogs from the top-level catalog? What have people found
best?
Cheers,
-Tennessee
