163 163  1. //**Gateway exchange**~:// Gateway exchanges are an organized set of bilateral exchanges, in which several data and metadata collecting organizations or individuals agree to exchange the collected information with each other in a single, known format, and according to a single, known process. This pattern has the effect of reducing the burden of managing multiple bilateral exchanges (in data and metadata collection) across the sharing organizations/individuals. This is also a very common process pattern in the statistical area, where communities of institutions agree on ways to gain efficiencies within the scope of their collective responsibilities.
164 164  1. //**Data-sharing exchange**~:// Open, freely available data formats and process patterns are known and standard. Thus, any organization or individual can use any counterparty’s data and metadata (assuming they are permitted access to it). This model requires no bilateral agreement, but only requires that data and metadata providers and consumers adhere to the standards.

175 175  Statistical data and metadata exchanges employ many different automated processes, but some are of more general interest than others. There are some common information technologies that are nearly ubiquitous within information systems today. [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] aims to provide standards that are most useful for these automated processes and technologies.

Although not strictly an aspect of exchange, this type of automated processing represents a set of requirements that must be supported if the information exchange between counterparties is itself to be supported.

211 211  It is important to note that [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] is primarily focused on the //exchange// and //dissemination// of statistical data and metadata. There may also be many uses for the standard model and formats specified here in the context of internal processing of data that are not concerned with the exchange between organizations and users, however. It is felt that a clear, standard formatting of data and metadata for the purposes of exchange and dissemination can also facilitate internal processing by organizations and users, but this is not the focus of the specification.

383 383  The [[Statistical Subject-Matter Domains>>doc:sdmx:Glossary.Statistical subject-matter domain.WebHome]] is a listing of the breadth of statistical information for the purposes of organizing widespread statistical exchange and categorization. It acts as a standard scheme against which the categorization schemes of various counterparties can be (% style="color:#e74c3c" %)mapped(%%), to facilitate interoperable data and metadata exchange. It serves another useful purpose, however, which is to allow an organization of corresponding “domain groups”, each of which could define standard [[data structure definitions>>doc:sdmx:Glossary.Data structure definition.WebHome]], (% style="color:#e74c3c" %)concepts(%%), etc. within their domains. Such groups already exist within the international community. [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] would use the [[Statistical Subject-Matter Domains>>doc:sdmx:Glossary.Statistical subject-matter domain.WebHome]] list to facilitate the efforts of these groups to develop the kinds of content standards which could support the interoperation of [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]]-conformant technical systems within and across [[statistical domains>>doc:sdmx:Glossary.Statistical subject-matter domain.WebHome]]. The organisation of the content of such schemes is supported in [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] as a [[Category>>doc:sdmx:Glossary.Category.WebHome]] Scheme.
