Hello all,

Here is an EML-related question.  The general broad question would be 
like this:
 
You are describing a large dataset (300,000 rows + 10-15 columns), and 
you naturally want to put a direct link to the actual data table in your 
well
documented EML.   What do you do?

Here is more info, if you feel you need more.

Your data may be in Oracle (or other DB) and a parametrized query (in 
the URL) on ALL data would slow down the server to a crawl.
Yes, it is a time series of weather stations data, with sampling every 
15 secs at best.

Do we run a cron job -- a full query every so often --, zip the results 
in a file that is overwritten (updated)?
Do you just place a link to the query page? A web service?


<distribution>
       <online>
            <url>  the url comes here.

* LTER Best practices encourages you to point to the data entity.
                                       
Cheers,
Inigo
