This is considered as the default mapping method and is applied unless a different method is specified through the VtlMappingScheme and VtlDataflowMapping classes. When transforming **from SDMX to VTL**, this method consists in leaving the components unchanged and maintaining their names and roles, according to the following table: 208 208 209 -|**SDMX**|**VTL** 210 -|Dimension|(Simple) Identifier 211 -|TimeDimension|(Time) Identifier 209 +(% style="width:529.294px" %) 210 +|(% style="width:151px" %)**SDMX**|(% style="width:375px" %)**VTL** 211 +|(% style="width:151px" %)Dimension|(% style="width:375px" %)(Simple) Identifier 212 +|(% style="width:151px" %)TimeDimension|(% style="width:375px" %)(Time) Identifier 213 +|(% style="width:151px" %)Measure|(% style="width:375px" %)Measure 214 +|(% style="width:151px" %)DataAttribute|(% style="width:375px" %)Attribute 212 212 213 -[[image:SDMX 3-0-0 SECTION 6 FINAL-1.0_en_59eee18f.gif||alt="Shape4" height="1" width="192"]] 214 - 215 -|Measure|Measure 216 -|DataAttribute|Attribute 217 - 218 218 The SDMX DataAttributes, in VTL they are all considered "at data point / observation level" (i.e. dependent on all the VTL Identifiers), because VTL does not have the SDMX AttributeRelationships, which defines the construct to which the DataAttribute is related (e.g. observation, dimension or set or group of dimensions, whole data set). 219 219 220 220 With the Basic mapping, one SDMX observation^^27^^ generates one VTL data point.
