A number of governments are starting to publish their statistical data online as Linked Data, using lightweight RDF vocabularies, such as SCOVO. The semantics of the statistical data points, such as real-world concepts they describe, is typically not explicit in these representations. We propose to make the semantics explicit by grounding the statistical data in existing vocabularies for real-world concepts and mathematical functions. This enables the integration with computation infrastructure and fosters easy access to the enhanced expressivity in Wiki collaboration environments where the statistical vocabularies are developed.
Read more about SCOVO Link in the WebSci10 paper Semantics of Governmental Statistics Data.

*Argument*
– an argument of a mathematical operation

- URI:
- http://vocab.deri.ie/scovolink#Argument
- Properties include:
- scovolink:argName, scovolink:argPosition, scovolink:argValue
- Used with:
- scovolink:arguments

*CountDataset*
– a statistical dataset that counts things

*Operation*
– a mathematical operation (e.g. used to compute derived statistical data items)

- URI:
- http://vocab.deri.ie/scovolink#Operation
- Properties include:
- scovolink:arguments, scovolink:function
- Used with:
- scovolink:computedFrom

*argName*
– the name of a named argument of a mathematical operation

- URI:
- http://vocab.deri.ie/scovolink#argName
- Domain:
- scovolink:Argument
- Range:
- xsd:NCName

This is the datatype of the OMV/@name attribute, i.e. the names of variables in OpenMath's mathematical objects.

*argPosition*
– the position of a positional argument of a mathematical operation, a positive integer

- URI:
- http://vocab.deri.ie/scovolink#argPosition
- Domain:
- scovolink:Argument
- Range:
- xsd:nonNegativeInteger

*argValue*
– the value of an argument of a mathematical operation. The value can be a statistical data item (scv:Item), so the actual numerical value is expected to be the rdf:value of that item.

- URI:
- http://vocab.deri.ie/scovolink#argValue
- Domain:
- scovolink:Argument
- Range:
- rdfs:Resource

*arguments*
– The arguments of a mathematical operation.

- URI:
- http://vocab.deri.ie/scovolink#arguments
- Domain:
- scovolink:Operation
- Range:
- scovolink:Argument

*classCardinality*
– The number of different individuals that instantiate the given class.

- URI:
- http://vocab.deri.ie/scovolink#classCardinality
- Domain:
- rdfs:Class
- Range:
- xsd:nonNegativeInteger

*computedFrom*
– The mathematical operation used to compute this statistical data item.

- URI:
- http://vocab.deri.ie/scovolink#computedFrom
- Domain:
- scovo:Item
- Range:
- scovolink:Operation

Note: right domain? Do we need something like a subclass DerivedItem?

*counts*
– The class of things that this dataset counts.

- URI:
- http://vocab.deri.ie/scovolink#counts
- Domain:
- scovolink:CountDataset
- Range:
- rdfs:Resource

*entitytypeDimension*
– The class of entity types that this dataset counts.

- URI:
- http://vocab.deri.ie/scovolink#entitytypeDimension
- Domain:
- scovolink:CountDataset
- Range:
- rdfs:Resource

Note: what should be the rdfs:range?

*function*
– The mathematical function that is applied to some arguments in order to perform this mathematical operation.

- URI:
- http://vocab.deri.ie/scovolink#function
- Domain:
- scovolink:Operation
- Range:
- rdfs:Resource

Note: Do we want to restrict it to OpenMath symbols? This would be the corresponding concept in the OpenMath ontology. Maybe we want to leave it open, or introduce a SCOVOLink-specific class here, if any. For now, we'll do without, as it depends on https://trac.mathweb.org/OM3/ticket/117

*georegionDimension*
– the class of geographical regions that constitute the geographical dimension of this dataset

- URI:
- http://vocab.deri.ie/scovolink#georegionDimension
- Domain:
- scovolink:CountDataset
- Range:
- rdfs:Resource

*numberOfDimensions*
– The number of dimensions of a dataset that counts things.

*timepointDimension*
– the class of points in time that constitute the temporal dimension of this dataset

- URI:
- http://vocab.deri.ie/scovolink#timepointDimension
- Domain:
- scovolink:CountDataset
- Range:
- rdfs:Resource
