The schema defines a target namespace (e.g. urn:schemas-teradp-com:gn4default), that is the namespace used by the import/export of XML files. This namespace is arbitrary – any unique string can be used. It is customary to use the prefix ‘urn:schemas-teradp-com:’ for Tera-generated namespaces.

The namespace of the schema is stored in a separate column in gn_SchemaTable when the schema is imported.

If a new schema with significant changes is imported in the database, it it is recommended to change the namespace. Note that this will make old XML files exported from the database no longer readable, (but if the schema is very different this might already be the case).
