Andrews Forest Metadata System

Andrews Forest LTER Metadata Management System Summary

The Andrews site stores their metadata using an SQL relational database. The database is the center piece of the Andrews metadata management system, and the transactions with the public and the users are coded in ColdFusion. Data are served directly from the database, although a few data files still reside in the file system (but are planned to be moved to the SQL database). The Andrews follows a metadata driven information system, and in their dynamic website offer rich metadata in both the raw XML as well as eye-friendly formats.

The Andrews Detailed

The Andrews site stores their metadata using a Windows Structured Query Language (SQL) database. The database is the center piece of the Andrews metadata management system, and the transactions with the public and the users are coded in ColdFusion. The scripts allow users to query, view and download metadata and data on the Andrew's dynamic website. The Andrews follows a metadata driven information system, and generates rich EML documents that are offered both in their website and the central repositories. Data are served directly from the database. Although a few data files may still reside in the file system, but will be migrated eventually. In addition, the Andrews uses an ArcGis server to manage their geospatial datasets, which are a significant portion of the Andrews data collection.

EML Status:

  • Completion: All metadata are available in EML.
  • Richness : All datasets have rich documentation, up to the attribute level (level 5)
  • QA/QC : There are some mechanisms to ensure the quality of the metadata and data, mostly manual entries in the back end database, some automated mechanisms are being implemented to ease the quality assurance tasks.
