154 154  This document specifies the [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] standards designed to facilitate exchanges based on any of these process patterns, and shows how [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] offers advantages in all cases. It is possible to agree bilaterally to use a standard format (such as [[SDMX-ML>>doc:Glossary.SDMX-ML.WebHome]] or [[SDMX-JSON>>doc:Glossary.SDMX-JSON.WebHome]]); it is possible for data senders in a gateway process to use a standard format for data exchange with each other, or with any [[data providers>>doc:Glossary.Data provider.WebHome]] who agree to do so; it is possible to agree to use the full set of [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] standards to support a common data-sharing process of exchange, whether based on an [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]]-conformant registry or some other architecture.

156 -The standards specified here specifically support a data-sharing process based on the use of central registry services. Registry services provide visibility into the data and metadata existing within the community, and support the access and use of this data and metadata by providing a set of triggers for automated processing. The data or metadata itself is not stored in a central registry – these services merely provide a useful set of metadata about the data (and additional metadata) in a known location, so that users/applications can easily locate and obtain whatever data and/or metadata is registered. The use of standards for all data, metadata, and the registry services themselves is ubiquitous, permitting a high level of automation within a data-sharing community.

158 158  It should be pointed out that these different process models are not mutually exclusive – a single system capable of expressing data and metadata in [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]]-conformant formats could support all three scenarios. Different standards may be applicable to different processes (for example, many registry services interfaces are used only in a data-sharing scenario) but all have a common basis in a shared information model.
