7 -The scope of the [[MSD>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]] is reduced in [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 3.0, by means of simplifying its structure, but also in the way referenced [[Artefacts>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] are targeted. In fact, the [[MSD>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]] is restricted to play the role of a single container, without targeting any specific [[Artefact>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]]. The possible targets of [[Metadata Set>>doc:sdmx:Glossary 2\.1.Metadata set.WebHome]] are specified in the [[Metadataflows>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] or Metadata [[Provision Agreements>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] relating to that [[MSD>>doc:sdmx:Glossary 2\.1.Metadata structure definition.WebHome]]. To achieve that, the structure of the [[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] has changed in this (% style="color:#e74c3c" %)version(%%) of the standard. Moreover, the Metadata [[Provision Agreement>>doc:sdmx:Glossary 2\.1.Provision agreement.WebHome]] [[Artefact>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] is introduced to include this feature.
