Dataset Metadata Survey

This repo is the result of the ODI tech team's investigations into the different metadata standards in use to describe datasets. It is made up of three parts:

We found that if a datastore uses DCAT, we could potentially match:

  • 6/18 requirements for basic level
  • 5/26 requirements for pilot level
  • 3/24 requirements for standard level
  • 2/16 requirements for exemplar level

However, some questions, such as if a dataset is machine readable or not, can be gleaned from things such as the format of the data.

We also found that very few of datastores we surveyed contained much usable metadata, although data.gov.uk, the Beta Ordnance Survey Open Data Linked Data Platform and Open Data Communities have a good chunk of metadata available for analysis.
