Information on standards
editHow to specify a standard?
- easy cases when a property exists: ISO (ISO standard (P503)) and RFC (RfC ID (P892))
- others cases : use described at URL (P973) if there is a link to the standard or described by source (P1343) if there is a wikidata entity for the standard
- if the kind of standard is known, add a genre (P136) to give the information, like W3C Recommendation (Q2661442)
- if the organisation in charge of the standard is wikidata entity , add a described at URL (P973), like International Telecommunication Union (Q376150)
Title | ID | Data type | Description | Examples | Inverse |
---|---|---|---|---|---|
ISO standard | P503 | External identifier | ISO standard: numeric identifier of this ISO standard | JPEG 2000 <ISO standard> 15444 | - |

How to specify if a file format is proprietary?
The idea is to use proprietary file format (Q2720536) to tell this information either in instance of (P31) or in subclass of (P279)
Title | ID | Data type | Description | Examples | Inverse |
---|---|---|---|---|---|
instance of | P31 | Item | instance of: that class of which this subject is a particular example and member; different from P279 (subclass of); for example: K2 is an instance of mountain; volcano is a subclass of mountain (and an instance of volcanic landform) | ACE <instance of> proprietary file format | - |
subclass of | P279 | Item | subclass of: this item is a subclass (subset) of that item; all instances of this item are instances of that item; different from P31 (instance of), e.g.: volcano is a subclass of mountain (and an instance of volcanic landform); K2 is an instance of mountain | Photoshop File Format <subclass of> proprietary file format | - |
The inverse is free format (Q8436198), but it could be usefull to specify copyright license (P275) with either a specific licence or public domain (Q19652), free license (Q196294), ...
Query for signature
editThe following query uses these:
- Properties: file format identification pattern (P4152) , encoding (P3294)
SELECT ?item ?itemLabel ?pattern ?encodage ?encodageLabel WHERE { ?item p:P4152 ?patternStatement. ?patternStatement ps:P4152 ?pattern. ?patternStatement pq:P3294 ?encodage. SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". } # PRONOM internal signature FILTER (str(?encodage) != 'http://www.wikidata.org/entity/Q35432091') # HEXA pattern #FILTER (str(?encodage) != 'http://www.wikidata.org/entity/Q82828') # ASCII pattern FILTER (str(?encodage) != 'http://www.wikidata.org/entity/Q8815') }
Query all RIFF formats
editThe following query uses these:
- Properties: instance of (P31) , subclass of (P279) , based on (P144)
SELECT DISTINCT ?item ?itemLabel WHERE { ?item (wdt:P31|wdt:P279)* wd:Q235557. ?item wdt:P144+ wd:Q1196805. SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". } }
