Arctic LTER Metadata System

Arctic LTER Metadata Management System Summary

The Arctic LTER (ARC) site stores their metadata in a structured filesystem. Metadata is gathered with an advanced Excel sheet that has evolved from an earlier Word based form sheet. The enhancements were partially inspired by the Florida Coastal LTER metadata capturing system (Excel2EML). The Excel workbook includes both metadata and data worksheets and does not use macros for entering information. A separate Excel workbook used by the Information Manager (IM) contains Excel macros (using Visual Basic for Applications) for parsing the metadata worksheet to create an EML and HTML files. The harvest list file tracks dataset metacat ID numbers. Geospacial data is served through Toolik Field Station GIS and Remote Sensing protal.

EML Status:

  • Completion: Nearly all metadata is available in EML.
  • Richness : Ranges from discovery level to the attribute level (levels 2 to 4)
  • QA/QC : Research investigators, assistants and students who collect the data are responsible for data analysis, quality control, and documentation. This insures that the data are checked and documented by those most familiar with the data.
