EML status of LTER sites

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.

How is LTER’s EML?
Future –
What needs to be done?
WHY?

EML status of LTER sites
LTER’s 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% ?

harvested About to be harvested to an high EML level
harvested Has very rich EML metadata
harvested Has implemented EML level 3ish. (To complete: Entity table)
Focus on site reorganization process long term plans
harvested Working on EML implementation and harvest as we speak
harvested Positively intrigued about it
harvested 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
