67 67  * **[[SDMX Registry>>doc:sdmx:Glossary 2\.1.SDMX Registry.WebHome]]**: Provision is made in the 2.0 standard for standard communication with registry services, to support a data-sharing model of statistical exchange. These services include registration of data and metadata, querying of registered data and metadata, and [[subscription>>doc:sdmx:Glossary 2\.1.Subscription.WebHome]]/[[notification>>doc:sdmx:Glossary 2\.1.Notification.WebHome]].
68 68  * **[[Structural Metadata>>doc:sdmx:Glossary 2\.1.Structural metadata.WebHome]]**: The support for exchange of statistical data and related [[structural metadata>>doc:sdmx:Glossary 2\.1.Structural metadata.WebHome]] has been expanded. Some support is provided for qualitative data; data cube structures are described; [[hierarchical code>>doc:sdmx:Glossary 2\.1.Hierarchical code.WebHome]] lists are supported; relationships between data structures can be expressed, providing support for extensibility of data structures; and the description of functional dependencies within cubes are supported.
