The INSPIRE Implementing Rules for Metadata requires that a set of metadata elements shall be provided. These are grouped in the following categories:
-
Identification
-
Classification of spatial and data services
-
Keyword
-
Geographic location
-
Temporal reference
-
Quality and validity
-
Conformity
-
Constraint related to access and use
-
Organisations responsible for the establishment, management, maintenance and distribution of the resource
-
Metadata on metadata
These are realized as a set of elements shown below. These may be implemented in various ways including ISO 19115 and Dublin Core. UK GEMINI is an ISO 19115 implementation.
