Niwot Ridge Metadata System

The Niwot Ridge LTER Metadata Management System Summary

The Niwot Ridge LTER site (NWT) their metadata and data are in a relational database and flat text files. An array of data entry formats merge into either of these back end systems, after a curation process. Scripts allow users to query, view and download metadata and data. Rich metadata is offered both as raw EML and also in an easy to read header section of the flat file data files.

The Niwot Ridge LTER Detailed

Niwot uses a number of different entry data points, from dataloggers to hand written data forms. After initial archival and backup, data is curated, derived and passed into a final archival mode in a relational database or an structured filesystem, perl or visual basic scripts and a few unix based tools tailor the data for public consumption at the Niwot server. Perl scripts parse updated metadata from the relational system to offer the metadata in the LTER network standard. The link below could not illustrate better the data management flow.

EML Status:

  • Completion: All metadata is available in EML (not all GIS data - still have issues w/ raster metadata conversion).
  • Richness : All EML documents are very rich, to the attribute level (levels 5)
  • QA/QC : There are systematic mechanisms to ensure the quality of the metadata and data.
