Overview diagram

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.

Classes

Class: scovolink:Argument

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

Class: scovolink:CountDataset

CountDataset – a statistical dataset that counts things

URI:: http://vocab.deri.ie/scovolink#CountDataset
Properties include:: scovolink:numberOfDimensions, scovolink:counts, scovolink:entitytypeDimension, scovolink:georegionDimension, scovolink:timepointDimension

Class: scovolink:Operation

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

Properties

Property: scovolink:argName

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.

Property: scovolink:argPosition

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

Property: scovolink:argValue

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

Property: scovolink:arguments

arguments – The arguments of a mathematical operation.

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

Property: scovolink:classCardinality

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

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

Property: scovolink:computedFrom

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?

Property: scovolink:counts

counts – The class of things that this dataset counts.

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

Property: scovolink:entitytypeDimension

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?

Property: scovolink:function

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

Property: scovolink:georegionDimension

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

Property: scovolink:numberOfDimensions

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

URI:: http://vocab.deri.ie/scovolink#numberOfDimensions
Domain:: scovolink:CountDataset
Range:: xsd:nonNegativeInteger

Property: scovolink:timepointDimension

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
