Coweeta Metadata System

The Coweeta Metadata Management System Summary

The Coweeta LTER (CWT) site data management uses a dynamically-generated searchable/indexed data catalog to keep track of the contributions to the project since its inception. All relevant data is available on the web, including the associated data files. Several formats are offered, including csv, dbf and flat text for the data, and HTML or and EML for metadata. For GIS data, there are other appropriate formats for the data files.

The Coweeta Detailed

The key to Coweeta's data manaegment system is that a researcher can only begin his/her work when the data management system has allocated a place for the project. Coweeta expects that the user inmediately begins documenting the project and provides rich metadata and data in several formats. This grants good documentation from the start. Technically, all the metadata is entered by the user on forms that are available on the web. All information is revised by the Coweeta Information Manager, and published for anyone to see. The data format could be in as many as three formats, microsoft excel archives, database format files (DBF files) and comma delimited files. The metadata is available both in flat text as well as EML, with about 60% of very rich and quality controlled EML.

EML Status:

  • Completion: Nearly all metadata is available in EML.
  • Richness : Over half of the harvested EML is rich and the quality has been throughly controlled, attribute level (level 5), and the rest is about discovery level (3)
  • QA/QC : The CWT has done a tremendous effort to ensure the maximum possible quality of their data and metadata. The next release of EML will reflect that, upping to level 5
