org.apache.uima.resource.metadata.TypeSystemDescription
Description of a CAS TypeSystem. This implements MetaDataObject, which implements {@link org.apache.uima.util.XMLizable}, so it can be serialized to and deserialized from an XML element.
Type systems can declare that they {@link #getImports() import} other type systems. At runtime,these imports will be resolved to create a single logical type system.
Note that type system imports are not automatically resolved when a TypeSytemDescription is deserialized from XML. To resolve the imports, call the {@link #resolveImports()} method. Importresolution is done automatically when a CAS is created using a TypeSystemDescription.
Type systems can optionally be assigned a {@link #getName() name}, {@link #getDescription() description}, {@link #getVendor() vendor}, and {@link #getVersion() version}. It is recommended that these properties be set on any type system that is meant to be shared by (imported by) multiple components.
