problems converting xml files to turtle

[VladimirAlexiev]

I tried to convert the xml files to turtle:

# cd CGMES_2_4
# riot --formatted=turtle Nordic44_CGM_36f_MF.xml  1>Nordic44_CGM_36f_MF.ttl
19:03:13 WARN  riot            :: [line: 8, col: 31] {W119} A processing instruction is in RDF content. No processing was done.

## the problem is the double colon

# the problem is that rdf:parseType: 'Statements' is a non-standard CIM invention

Such statements are captured as rdf:XMLLiteral rather than RDF, eg:

dm:forwardDifferences  "\n\t  \t\t<cim:OperatingShare xmlns:cim=\"http://iec.ch/TC57/CIM/CIM100#\"
 xmlns:rdf=\"http://www.w3.org/1999/02/22-rdf-syntax-ns#\" 
rdf:about=\"urn:uuid:85e930e3-5409-4f2a-b343-5fd271d1a348\">\n\t\t\t\t
<!--Operating Participant B -->\n\t\t\t\t
<cim:OperatingShare.OperatingParticipant rdf:resource=\"urn:uuid:18e06751-54c1-44c8-86d9-0e9f5f358289\">
</cim:OperatingShare.OperatingParticipant>\n\t\t\t
</cim:OperatingShare>  \n\t  \n      "^^rdf:XMLLiteral

"<?iec61970-552 version="2.0""

this is sadly something that was added as part of IEC 61970-552:Ed2. I was a bit afraid this could be an issue. The MF model with go back to Ed1 and this will be remove.

riot --formatted=turtle Nordic44_03_inc.xml 1>Nordic44_03_inc.ttl

This items are a biggere challange, but we need to address incremenal as part of JSON-LD.

How about "You cannot include comments in the middle of attributes"?

I will move the previous version of Nordic44 (CGMES v2.4) to a separate repository so that we can run the Turle validation on the repository.
