Package org.opengis.util

A set of base types from ISO 19103 which can not be mapped directly from Java, plus utilities.

Names and Namespaces

The job of a "name" in the context of ISO 19103 is to associate that name with an Object. Examples given are objects: which form namespaces for their attributes, and Schema: which form namespaces for their components. A straightforward and natural use of the namespace structure defined in 19103 is the translation of given names into specific storage formats. XML has different naming rules than shapefiles, and both are different than NetCDF. This common framework can easily be harnessed to impose constraints specific to a particular application without requiring that a separate implementation of namespaces be provided for each format.

Records and Schemas

Records and Schemas are similar to a struct in C/C++, a table in SQL, a RECORD in Pascal, or an attribute-only class in Java if it were stripped of all notions of inheritance. They are organized into named collections called Schemas. Both records and schemas behave as dictionaries for their members and are similar to "packages" in Java.
