Interface Summary

Interface	Description
Cloneable	Indicates that it is legal to make a field-for-field copy of instances of implementing classes.
GenericName	A sequence of identifiers rooted within the context of a namespace.
InternationalString	A string that has been internationalized into several locales.
LocalName	Identifier within a name space for a local object.
MemberName	The name to identify a member of a record.
NameFactory	Factory for generic names and international strings.
NameSpace	A domain in which names given by character strings are defined.
ProgressListener	Monitor the progress of some lengthly operation, and allows cancelation.
Record	A list of logically related elements as (name, value) pairs in a dictionary.
RecordSchema	A collection of record types.
RecordType	The type definition of a record.
ScopedName	A composite of a local name (as head) for locating another name space, and a generic name (as tail) valid in that name space.
TypeName	The name of an attribute type.

Class Summary

Class	Description
CodeList<E extends CodeList<E>>	Base class for all code lists.
SimpleEnumerationType<E extends SimpleEnumerationType<E>>	Deprecated The name doesn't said what is the difference between this class and CodeList.
UnlimitedInteger	An integer with associated infinite flag.

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.
