  In addition to looking at collection and reporting, it is also important to consider the dissemination of data. Data and metadata – no matter how they are exchanged between counterparties in the process of their development and creation – are all eventually supplied to an end user of some type. Often, this is through specific applications inside of institutions. But more and more frequently, data and metadata are also published on websites in various formats. The dissemination of data and its accompanying metadata on the web is a focus of the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] standards. Standards for statistical data and metadata allow improvements in the publication of data – it becomes more easily possible to process a standard format once the data is obtained, and the data and metadata are linked together, making the comprehension and further processing of the data easier.
--In discussions of statistical data, there are many aspects of its dissemination which impact data quality: data discovery, ease of use, and [[timeliness>>doc:sdmx:Glossary 2\.1.Timeliness.WebHome]]. [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] standards provide support for all of these aspects of data dissemination. Standard data formats promote ease of use, and provide links to relevant metadata. The concept of registry services means that data and metadata can more easily be discovered. [[Timeliness>>doc:sdmx:Glossary 2\.1.Timeliness.WebHome]] is improved throughout the data lifecycle by increases in efficiency, promoted through the availability of metadata and ease of use.

  It is important to note that [[SDMX>>doc:sdmx:Glossary 2\.1.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.

  == 3.4 The SDMX View of Statistical Exchange ==
--Version 1.0 of ISO/TS 17369 [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] covered statistical [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] and the metadata related to the structure of these [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]. This scope was useful in supporting the different models of statistical exchange ([[bilateral exchange>>doc:sdmx:Glossary 2\.1.Bilateral exchange.WebHome]], gateway exchange, and data-sharing) but was not by itself sufficient to support them completely. Versions 2.0 and 2.1 provide a much more complete view of statistical exchange, so that an open data-sharing model can be fully supported, and other models of exchange can be more completely automated. In order to produce technical standards that will support this increased scope, the [[SDMX Information Model>>doc:sdmx:Glossary 2\.1.SDMX Information Model.WebHome]] provides a broader set of formal objects which describe the actors, processes, and resources within statistical exchanges.

  It is important to understand the set of formal objects not only in a technical sense, but also in terms of what they represent in the real-world exchange of statistical data and metadata.
--The first version of [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] provided for [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] - specific statistical data reported according to a specific structure, for a specific time range - and for [[data structure definitions>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] - the metadata which describes the structure of statistical [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]. These are important objects in statistical exchanges, and are retained and enhanced in the second version of the standards in a backward-compatible form. A related object in statistical exchanges is the "[[data flow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]" - this supports the concept of data reporting or dissemination on an ongoing basis. "[[Data flows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]" can be understood as [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] which are not bounded by time. Data structures are owned and maintained by agencies - in a similar fashion, [[data flows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] are owned by [[maintenance agencies>>doc:sdmx:Glossary 2\.1.Maintenance agency.WebHome]].

--[[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] allows for the publication of statistical data (and the related [[structural metadata>>doc:sdmx:Glossary 2\.1.Structural metadata.WebHome]]) but also provided for the standard, systematic [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] of [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]. In version 2.1, [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] were reported independent of the statistical data.

  However, in 3.0 [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] associated directly with data such as footnotes are reported as [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] of the [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]. For other [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]], principally that linked to structures like “[[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]]”, [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] provides reference "[[metadata sets>>doc:sdmx:Glossary 2\.1.Metadata set.WebHome]]", "[[metadata structure definitions>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]]", and "[[metadata flows>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]]". These objects are very similar to [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]], [[data structure definitions>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]], and [[data flows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]], but concern [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] rather than statistical observations. In the same way that [[data providers>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]] may publish statistical data, they may also publish [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]. Metadata structural definitions are maintained by agencies in a fashion similar to the way that agencies maintain [[data structure definitions>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]], the structural definitions of [[data sets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]].
