Re: [dxwg] Related vocabularies mapping [RVM]

StatDCAT-AP is at https://joinup.ec.europa.eu/release/statdcat-ap-v100. It's a fairly basic profile, an extension of the European DCAT-AP. It adds a small number of properties to DCAT-AP:

```
<http://data.europa.eu/m8g/attribute> a rdf:Property ;
  rdfs:label "attribute"@en ;
  vann:usageNote "Aditional optional property. Cardinality [0..n]. This property links to a component used to qualify and interpret observed values, e.g. units of measure, any scaling factors and metadata such as the status of the observation (e.g. estimated, provisional). Attribute is a ‘conceptual’ entity that applies to all distribution formats, e.g. in case a dataset is provided both in SDMX and in Data Cube."@en ;
  rdfs:range qb:AttributeProperty .
  
<http://data.europa.eu/m8g/dimension> a rdf:Property ;
  rdfs:label "dimension"@en ;
  vann:usageNote "Aditional optional property. Cardinality [0..n]. This property links to a component that identifies observations, e.g. the time to which the observation applies, or a geographic region which the observation covers. Dimension is a ‘conceptual’ entity that applies to all distribution formats, e.g. in case a dataset is provided both in SDMX and in Data Cube."@en ;
  rdfs:range qb:DimensionProperty .
  
<http://data.europa.eu/m8g/numSeries> a rdf:Property ;
  rdfs:label "number of data series"@en ;
  vann:usageNote "Aditional optional property. Cardinality [0..n]. This property contains the number of data series contained in the Dataset. This property should be defined as rdfs:Lideral typed as xsd:date or xsd:dateTime."@en ;
  rdfs:range rdfs:Literal .
  
<http://www.w3.org/ns/dqv#hasQualityAnnotation> a rdf:Property ;
  rdfs:label "quality annotation"@en ;
  vann:usageNote "Aditional optional property. Cardinality [0..n]. This property links to a statement related to quality of the Dataset, including rating, quality certificate, feedback that can be associated to the Dataset."@en .
  
<http://data.europa.eu/m8g/statUnitMeasure> a rdf:Property ;
  rdfs:label "unit of measurement"@en ;
  vann:usageNote "Aditional optional property. Cardinality [0..n]. This property links to a unit of measurement of the observations in the dataset, for example Euro, square kilometre, purchasing power standard (PPS), full-time equivalent, percentage. Unit of measurement is a ‘conceptual’ entity that applies to all distribution formats, e.g. in the case when a dataset is provided both in SDMX and in Data Cube."@en ;
  rdfs:range skos:Concept .
```
You'll see that the ranges are from DataCube but it is not necessary that the objects are part of a QB description. As stated in the usage notes, those properties can apply irrespective of the encoding of the data, in SDMX or QB or otherwise.
