Matching Wikidata and CIM

Wikidata on one side, and CIM (WMI, WBEM) have classes and properties in common, but:

• the equivalence relations between them will never be one-to-one.
• they might be not stable, not normalised, changing without warning.

Where to store the CIM properties

The matching properties might not be stored in Wikidata, at first.

• There might be trial and error.
• It also involves property definitions strictly in Survol.
• Some ontologies are dynamically generated.

=> To start with, static RDF file on Survol site.

Storing WMI and WBEM ontologies

• RDF files stored on Survol site.

Exploring process (Q205663): CIM_Process

process (Q205663) instances

• instance of (P31): that class of which this subject is a particular example and member

Misplaced data here: "mastering", "Bids for the 2014 Winter Olympics", "Microbial biodegradation", "repatriation" ...

SELECT DISTINCT ?subjectLabel WHERE {
  ?subject wdt:P31 wd:Q205663 .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}

Try it!

process (Q205663) subclasses

• subclass of (P279): all instances of these items are instances of those items; this item is a class (subset) of that item.

Why does it also display these results ? "Q23394081" "economic development" "ethical consumerism"

SELECT DISTINCT ?subjectLabel WHERE {
  ?subject wdt:P279* wd:Q205663 .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}

Exploring computer file (Q82753): CIM_DataFile

Typical output: "C header file", "Wikimedia Commons file", "audio file" etc... With instance of (P31), it returns apparently books titles.

SELECT DISTINCT ?subjectLabel WHERE {
  ?subject wdt:P279* wd:Q82753 .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}
ORDER BY ?subjectLabel

Exploring directory (Q201456): CIM_Directory

directory (Q201456) instances

Typical output: "/bin", "/dev", "Program Files" but also "Cinémathèque québécoise".

SELECT DISTINCT ?subjectLabel WHERE {
  ?subject wdt:P31* wd:Q201456 .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}
ORDER BY ?subjectLabel

Try it!

directory (Q201456) subclasses

Typical output: directory, home directory, mount point, podcast directory, root directory, special folder, working directory.

SELECT DISTINCT ?subjectLabel WHERE {
  ?subject wdt:P279* wd:Q201456 .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}
ORDER BY ?subjectLabel
