  A //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// is a collection of a set of //Observation//s that share the same dimensionality, which is specified by a set of unique [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] ([[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]], TimeDimension) defined in the DimensionDescriptor of the DataStructureDefinition, together with associated //AttributeValue//s that define specific characteristics about the [[artefact>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]] to which it is attached – //Observation//s, set of [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]. It can be structured in terms of a SeriesKey to which //Observation//s are reported.
--The //Observation// can be the value(s) of the variable(s) being measured for the [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] associated to the Measure(s) in the MeasureDescriptor of the DataStructureDefinition. Each //Observation// associates one or more //ObservationValue//s with a KeyValue (+observationDimension) which is the value for the “[[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] at the Observation Level”. Any [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] can be specified as being the “[[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] at the Observation Level”, and this specification is made at the level of the //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// (i.e., it must be the same [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] for the entire //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]//).
++The //Observation// can be the value(s) of the variable(s) being measured for the (% style="color:#e74c3c" %)Concept(%%) associated to the Measure(s) in the MeasureDescriptor of the DataStructureDefinition. Each //Observation// associates one or more //ObservationValue//s with a KeyValue (+observationDimension) which is the value for the “[[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] at the Observation (% style="color:#e74c3c" %)Level(%%)”. Any [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] can be specified as being the “[[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] at the Observation (% style="color:#e74c3c" %)Level(%%)”, and this specification is made at the (% style="color:#e74c3c" %)level(%%) of the //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]// (i.e., it must be the same [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] for the entire //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]//).
  The //KeyValue// is a value for one of TimeDimension or [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] specified in the DataStructureDefinition. If it is a [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]], it can be coded (CodedKeyValue) or uncoded (UncodedKeyValue). If it is the TimeDimension then it is a TimeKeyValue. The actual value that the CodedDimensionValue can take must be one of the [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] in the [[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] specified as the [[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] of the [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] in the DataStructureDefinition.
  An ObservationValue can be coded – this is the CodedObservation – or it can be uncoded – this is the UncodedObservation. In the case of uncoded observations, the values may be multilingual – expressed via the TextMeasureValue – or not (OtherUncodedMeasureValue).
--The GroupKey is a subunit of the //Key// that has the same dimensionality as the SeriesKey but defines a subset of the KeyValues of the SeriesKey. Its sub [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] structure is defined in the GroupDimensionDescriptor of the DataStructureDefinition identified by the same id as the GroupKey. The id identifies a “type” of group and the purpose of the GroupKey is to report one or more //AttributeValue// that are contained at this group level. The GroupKey is present when the GroupDimensionDescriptor is related to the GroupRelationship in the DataStructureDefinition. There can be many types of groups in a //[[DataSet>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]//. If the Group is related to the DimensionRelationship in the DataStructureDefinition then the //AttributeValue// will be reported with the appropriate [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] in the SeriesKey or Observation.

The allowable [[Concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] and the objects to which these metadata can be associated (attached) are defined in the DataStructureDefinition and the linked MetadataStructureDefinition.
