EML status of LTER sites
Almost all the LTER sites have implemented the
EML standard. The same LTER sites, have made
EML metadata available at centralized servers.
These Metacat servers have harvested 4,900
EML documents from LTER sites. Harvested" here
is loosely defined as  at least a few metadata
sets of low content placed in the server. Also,
the site has a good plan to place all legacy data
in, and with specific plans to enrich EML, if
appropriate. Over half of the LTER sites have
attribute-level EML. This means that potentially,
the associated data can be accessed and
interpreted programatically.

EML status of LTER sites
LTERs EML past Last year, some sites had yet
to harvest, furthermore, some LTER sites had to
implement the EML standard. This text is taken
from last year EML Status report at the 2005 IM
Montreal meeting. Now we show how these sites
fared. How about the 25 ? FCE
About to be harvested to an high EML level
KNZ Has very rich EML metadata HFR
Has implemented EML level 3ish. (To complete
Entity table) PAL Focus on site
reorganization process long term plans
CDR Working on EML implementation and
harvest as we speak
BNZ Positively intrigued about it
JRN On the verge of posting
level 5 EML for 70 of datasets

EML status of LTER sites Present
You can see a first order categorization of the
EML Tier levels implemented at the sites There
are fine differences not noted in the figure,
such as the percentage of metadata converted to
EML and the precise richness content
