The Hubbard Brook Detailed

At HBR, a customized mySQL relational database stores all related info to datasets. This database tracks changes in data and metadata and allows data sets to be queried, browsed and viewed using Pre Hypertext Processor language (PHP) scripts. Some of the data are in raw text files and other data are stored in a database: it depends of the data category, whether watershed studies, climate studies or more point studies. There is a tendency to sort out in a database the larger systematic datasets. Rich EML is available for all datasets, and currently maintained manually. The site is mulling improved management options for the EML.

EML Status:

  • Completion: All metadata is available in EML.
  • Richness : Nearly all EML documents are very rich, to the attribute level (levels 5)
  • QA/QC : There are mechanisms to ensure the quality of the metadata and data ??
