Whitespace in Definitions

[VladimirAlexiev]

https://github.com/Sveino/Inst4CIM-KG/tree/develop/rdfs-improved#whitespace-in-definitions

Many definitions include leading/trailing whitespace (newlines, tabs etc), eg:

cim:Boolean a owl:Class ;
  rdfs:label "Boolean"@en ;
  dl:Package "Package_DiagramLayoutProfile" ;
  dl:isPrimitive "True" ;
  skos:definition """
A type with the value space "true" and "false".

\t"""@en .

This query finds 1556 instances of leading/trailing whitespace in strings. (I guess some are duplicated between 2.3 and 3.0 CIM namespaces):

select * {
    ?x ?p ?label
    filter(regex(?label,"^\\s|\\s$"))
}

See literals-whitespace.tsv

This query counts by property:

select ?p (count(*) as ?c) {
    ?x ?p ?label
    filter(regex(?label,"^\\s|\\s$"))
} group by ?p order by desc(?c)

p	c	comment
skos:definition	"660"^^xsd:integer
rdfs:label	"614"^^xsd:integer	Most of these are key values (see next section) but some are prop names. Eg ssh:isDescription has multiple trailing spaces or tab
rdfs:comment	"150"^^xsd:integer	This and all below are key values (see next section)
eq:isFixed	"43"^^xsd:integer
sc:isFixed	"24"^^xsd:integer
ssh:isFixed	"22"^^xsd:integer
dy:isFixed	"20"^^xsd:integer
sv:isFixed	"10"^^xsd:integer
dcterms:creator	"7"^^xsd:integer
dl:isFixed	"2"^^xsd:integer
eqbd:isFixed	"2"^^xsd:integer
op:isFixed	"2"^^xsd:integer

This can be fixed easily with SPARQL Update. Just need to be careful to restore a lang tag if such was present.

Some of the things are maybe in the RDFS export, some other maybe in the UML
