Structure

The MapX Metadata Standard is composed of:

• mandatory metadata elements (prevent saving metadata if they are not filled in)

• recommended metadata elements (minimum to be provided so that users can discover the data and determine if it is suitable for their use)

  Warning

  A warning sign is displayed in the interface to inform users that some recommended elements are missing (link).

• optional metadata elements to allow for a more detailed description of the data

Description of the MapX Metadata Standard

1. Text: textual description of the data using title, abstract and tags

   • Title ^m (multilingual): title given to the source in the MapX tools

   • Abstract ^m (multilingual): detailed description of the dataset

   • Additional notes (multilingual): any other relevant information to be provided to MapX users (processing performed on the data, modifications, disclaimer, citation, etc.)

   • Keywords: keywords (or tags) help users discover your data. Please include terms that can be used by a technical and non-technical audience.

     • Keywords ^r (user-defined)

     • Geographic Keywords ^m (based on Standard country or area codes for statistical use (M49) )

     • GEneral Multilingual Environmental Thesaurus (GEMET ) keywords

   • Attribute description (multilingual): description of the attributes contained in the dataset

   • Alias for attribute names: short names (aliases) for attributes can be defined in this section. It’s often valuable to replace technical or truncated attribute names by something clearer. For example, a source using the attribute name x_1Mp_mean would be more comprehensive with: “Average monthly precipitation [mm]”. Aliases are used when the attribute table is consulted or when an feature is queried in the map.
