What is Discovery Metadata?
Discovery Metadata is the minimum amount of information that needs to be provided to convey to the inquirer the nature and content of the data resource. This falls into broad categories to answer the what, why, when, who, where and how questions about geospatial data.


• What - title and description of the dataset.

• Why - abstract detailing reasons for the data collection.

• When - when the dataset was created and the update cycles if any.

• Who - originator and data supplier.

• Where - the geographical extent based on lat / long, co-ordinates, geographical names or administrative areas.

• How - how to obtain more information or order the datasets, formats, media access, constraints. These broad categories are only few in number to reduce the effort required to collect the information, whilst still conveying to the inquirer the nature and content of the data resource. However some categories require additional elements for full definition and therefore the total number of elements is 42. For example supplier name covers eight elements - name, address, contact, telephone number, etc.
