The Plum Island Site Detailed

The PIE site manages the data and metadata using a structured file system that follows the PIE research program areas to recreate a file shelving structure. Data files are in tabular text format, offered unrestricted to the public but according to the data policy guidelines. Data and metadata are originally captured in an MS Excel document to an attribute level. Metadata is offered through the PIE website and in EML format.

EML Status:

  • Completion: Nearly all flat file metadata is available in EML, GIS metadata is a work in progress.
  • Richness : Ranges from discovery level to the attribute level (levels 3 to 4)
  • QA/QC : Protocols to be added
