65 65  * **[[Reference Metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]**: In addition to describing and specifying data structures and formats (along with related [[structural metadata>>doc:sdmx:Glossary 2\.1.Structural metadata.WebHome]]), the version 2.0 specification also provides for the exchange of metadata which is distinct from the [[structural metadata>>doc:sdmx:Glossary 2\.1.Structural metadata.WebHome]] in the 1.0 version. This [[category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] includes “reference” metadata (regarding data quality, methodology, and similar types – it can be configured by the user to include whatever concepts require reporting); metadata related to data provisioning ([[release calendar>>doc:sdmx:Glossary 2\.1.Release policy - release calendar.WebHome]] information, description of the data and metadata provided, etc.); and metadata relevant to the exchange of categorization schemes.
66 66  * **[[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]].

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.
