Proposals for improvement of the text of the specification #41

Closed delcada closed 5 years ago

Below are some proposals for improvement of the text of the specification.

Each level is defined by its own concept, as the collection of concepts at a particular level have a common overall meaning. For instance, the first level below the root in the North American Standard Industrial Classification ([NAICS]) is known as Sectors, and Government is one of the sectors; these sectors are the broadest industry categories.

I would take another example than "Government" here (e.g. "Manufacturing", "Educational Services") because it could be confused with the "Government" institutional sector from the UN System of National Accounts which has a very specific meaning. Additionally, there is no "Government" sector in NAICS but a "Public Administration" sector.


Rewrite:

Further examples of statistical classifications are the ISCED for education, ISCO for occupations and NACE for economic activities ([ISCED], [ISCO], [ISIC], [NACE]). A complete overview of the statistical classifications that are used in the European Union is available at RAMON ([RAMON]).

as follows:

Further examples of statistical classifications are the ISCED for education, ISCO for occupations and ISIC for economic activities ([ISCED], [ISCO], [ISIC]). A complete overview of the main statistical classifications used at world (e.g. United Nations) and regional levels (e.g. European Union) is available at RAMON ([RAMON]).


The generic relation refers to type – sub-type, or "kind of", relationships. A person is a kind of mammal. Partitive relations are used to describe part – whole relationships. An engine is part of a car.

One could add: The former kind of relation is typical of thesauri (i.e. broader than/narrower than) while the latter is more typical of correspondence tables between statistical classifications (i.e. a category at a specific level of a classification is made of one or more parts at the level immediately below).


Such a collection of item associations is called a correspondance or conversion table, or sometimes a concordance. Further synonyms are correlation table and mapping.


SKOS contains the property skos:scopeNote which is a sub-property of skos:note which itself is a type of owl:annotationProperty. XKOS extends the property skos:scopeNote to define additional sub-properties needed to support the model described abover. The sub-properties added to skos:scopeNote include an xkos:inclusionNote and xkos:exclusionNote. Additional sub-properties were added to xkos:inclusionNote to further define the type of inclusion specification using the sub-properties xkos:coreContentNote (to identify central content) and xkos:additionalContentNote (to identify limit content).

One could add the following text to the para above:

In paper or electronic documents, xkos:coreContentNote is generally labelled "This category includes", "This item includes", "This division includes", "Includes" or similar; xkos:additionalContentNote is generally labelled "This category includes also", "This item includes also", "This division includes also", "Includes also", or similar. xkos:exclusionNote is generally labelled "This category excludes", "This item excludes", "This division excludes", "Excludes " or similar
