  The structural definitions of both data and [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] associate specific statistical [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] with their [[representations>>doc:sdmx:Glossary 2\.1.Representation.WebHome]], whether textual, coded, etc. These [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] are taken from a "[[concept scheme>>doc:sdmx:Glossary 2\.1.Concept scheme.WebHome]]" which is maintained by a specific agency. [[Concept schemes>>doc:sdmx:Glossary 2\.1.Concept scheme.WebHome]] group a set of [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]], provide their definitions and names, and allow for semantic relationships to be expressed, when some [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] are specializations of others. It is possible for a single [[concept scheme>>doc:sdmx:Glossary 2\.1.Concept scheme.WebHome]] to be used both for data structures - key families - and for [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] structures.
--Inherent in any statistical exchange – and in many dissemination activities – is a concept of "service level agreement", even if this is not formalized or made explicit.
