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.

    //serialize to XMI
    String xmiStr = serialize(cas, null);
    
    //deserialize into a CAS that's missing the Organization type
    File partialTypeSystemFile = JUnitExtension.getFile("ExampleCas/partialTestTypeSystem.xml");
    TypeSystemDescription partialTypeSystem = UIMAFramework.getXMLParser().parseTypeSystemDescription(
            new XMLInputSource(partialTypeSystemFile));
    testAnnotTypeDesc = partialTypeSystem.addType("org.apache.uima.testTypeSystem.TestAnnotation", "", "uima.tcas.Annotation");
    testAnnotTypeDesc.addFeature("arrayFeat", "", "uima.cas.FSArray");
    CAS partialTsCas = CasCreationUtils.createCas(partialTypeSystem, null, null);
    XmiSerializationSharedData sharedData = new XmiSerializationSharedData();
    deserialize(xmiStr, partialTsCas, sharedData, true, -1);
