6 6  
7 -The scope of the [[MSD>>doc:Glossary.Metadata structure definition.WebHome]] is reduced in [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] 3.0, by means of simplifying its structure, but also in the way referenced [[Artefacts>>doc:Glossary.Artefact.WebHome]] are targeted. In fact, the [[MSD>>doc:Glossary.Metadata structure definition.WebHome]] is restricted to play the role of a single container, without targeting any specific [[Artefact>>doc:Glossary.Artefact.WebHome]].

To achieve that, the structure of the [[Metadataflow>>doc:Glossary.Metadataflow.WebHome]] has changed in this (% style="color:#e74c3c" %)version(%%) of the standard. Moreover, the Metadata [[Provision Agreement>>doc:Glossary.Provision agreement.WebHome]] [[Artefact>>doc:Glossary.Artefact.WebHome]] is introduced to include this feature.
