241	241	* //**[[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] Definition:**// A [[metadata flow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] definition is very similar to a [[data flow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] definition, but describes, categorises, and constrains [[metadata sets>>doc:sdmx:Glossary 2\.1.Metadata set.WebHome]].
242	242	* //**[[Data Provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]]: **//An organization which produces data is termed a [[data provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]].

A [[provision agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] can be constrained in much the same way as a data or [[metadata flow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] definition. Thus, a [[data provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]] can express the fact that it provides a particular [[data flow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] covering a specific set of countries and topics, Importantly, the actual source of registered data or metadata is attached to the [[provision agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] (in terms of a URL). The term “agreement” is used because this information can be understood as the basis of a “service-(% style="color:#e74c3c" %)level(%%) agreement”. In [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]], however, this is informational metadata to support the technical systems, as opposed to any sort of contractual information (which is outside the scope of a technical specification). In (% style="color:#e74c3c" %)version(%%) 3.0, metadata [[provision agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] and data [[provision agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] are two separate [[artefacts>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]].

248	248	* //**Structure (% style="color:#e74c3c" %)Map(%%): **//Structure (% style="color:#e74c3c" %)maps(%%) describes a mapping between [[data structure definitions>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] or [[dataflows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] for the purpose of transforming a [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] into a different structure. The mapping rules are defined using one or more [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] (% style="color:#e74c3c" %)maps(%%) which each (% style="color:#e74c3c" %)map(%%) in turn describes how one or more [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] from the source [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] (% style="color:#e74c3c" %)map(%%) to one or more [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] in that of the target.

The (% style="color:#e74c3c" %)version(%%) 3.0 information model provides four [[item scheme>>doc:sdmx:Glossary 2\.1.Item scheme.WebHome]] (% style="color:#e74c3c" %)maps(%%): organisation scheme (% style="color:#e74c3c" %)map(%%), [[concept scheme>>doc:sdmx:Glossary 2\.1.Concept scheme.WebHome]] (% style="color:#e74c3c" %)map(%%), [[category scheme>>doc:sdmx:Glossary 2\.1.Category scheme.WebHome]] (% style="color:#e74c3c" %)map(%%) and [[reporting taxonomy>>doc:sdmx:Glossary 2\.1.Reporting taxonomy.WebHome]] (% style="color:#e74c3c" %)map(%%).
