Metadata is used by GeoTools to describe GeoSpatial information and services. The data structure is an implementation of ISO19115 (for metadata describing spatial data).

The gt-metadata module also pulls double duty as the first implementation module it is responsible for providing the facilities we use to wire the library together at runtime.

The gt-metadata module is responsible for:

  • implementation of the metadata interfaces from gt-opengis such as Citation and Identifier

  • Configuring the library at runtime with GeoTools and FactoryRegistry and Logging facilities

  • Utility classes with helpful implementations for Collections, Caching and Object pools

  • Default set of Converters supporting basic Java types
