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.

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% ?
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 ”

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
