Understanding metadata

What is metadata?

Metadata is descriptive information about a dataset. Metadata is important because it makes it easier to find and check the data you need.

Because datasets can be quite complex, and can be described in many different ways, data tends to be described using one of several international metadata schemas. While these metadata schemas can appear quite complex, they are intended to provide all the relevant information a user will need to put the data to use.

What metadata schemas are supported by Koordinates?

The three metadata schemas supported by Koordinates are:

  • Dublin Core, a generic metadata schema that is used to describe objects on the web
  • ISO 19115/19139, a metadata schema specific to geospatial data and information
  • FGDC CSDGM, a metadata scheme for geospatial data established by the US Federal Geographic Data Committee

How is metadata downloaded by users?

Metadata can be downloaded in PDF and XML. A copy of the metadata is included in all data downloads from a Koordinates powered site. Publishers can choose which options are available to end users.
