------- Comment #1 from jones at nceas.ucsb.edu  2006-06-28 10:19 -------
In EML you can specify multiple, dicontiguous time periods by repeating the
coverage element.  No need to have two separate holdings for this.

With respect to ongoing data collection, this issue has been raised before. 
EML documents the data that you already have for the purposes of more accurate
search and interpretation.  At any given point in time when you distribute a
dataset with an EML document, the data will be from a finite temporal coverage,
and that is what should be indicated in the documentation.  If in the future
you incude new records, simply modify the EML to reflect the new coverage at
that time.

If you plan on collecting additional data in the future, the best place to
indicate this is in your methods and sampling design descriptions. 
Unfortunately, adding an end date of 'present' doesn't really tell us much from
a search or interpretation perspective.  For example, if someone says their
data covers 1990-present, and the metadata was produced in 2001, should I
expect to find data from 2006 in that data set when I search?  Should it be
returned as a hit in a search for data in 2006?  Probably not, as the best laid
plans often go awry.  The only reliable thing to document over the long term is
the data you actually have in hand.

I htink there are no new issues in this bug report, so unless further comments
reflect something that should be changed in EML I will close the bug report
shortly.
