SPARQL querying from Informatics by topic[edit]

The intention is to explore various classes and properties created by the project Wikidata:WikiProject Informatics.

Concrete software objects[edit]

This enumerates technical and concrete software objects, described in Informatics, which are the building blocks of a process running an application. The general criteria are:

INCLUDED

  • Arguments of system calls.
  • Things which can be displayed by a command, or taken as a command parameter.

EXCLUDED

  • Concepts, patterns, standards, general terms: These do not appear in a binary program or library etc...
  • Brands, except as an aside information about a technical object.
  • Physical devices except if visible from software, and then, just mentioned. The reason is that this works focuses only on software objects.

Operating system objects[edit]

Linux objects[edit]

Network IOs[edit]

File IOs[edit]

DBs[edit]

Message queues[edit]

Programming[edit]

Compiled programs structure[edit]

Programming[edit]

Python[edit]

System calls[edit]

... etc ...

Amazon services[edit]

Brands etc...[edit]

SPARQL technical queries from Informatics[edit]

Querying from FOAF with "select from"[edit]

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
SELECT  ?name
FROM    <http://example.org/foaf/aliceFoaf>
WHERE   { ?x foaf:name ?name }
Try it!

This returns the error: 

Unknown error: NAMED clauses in queries are not supported in triples mode.

Querying from Survol with "select from"[edit]

This fails with the same error message. 

SELECT  *
FROM    <http://vps516494.ovh.net/Survol/survol/sources_types/enumerate_CIM_Process.py?xid=.&mode=rdf>
WHERE {}
Try it!

Federated query from DBPedia[edit]

PREFIX dbc: <http://dbpedia.org/resource/Category:>
PREFIX dct: <http://purl.org/dc/terms/>
SELECT ?wsubjectLabel WHERE {
    SERVICE <http://dbpedia.org/sparql> {
         ?subject dct:subject dbc:American_rock_singers .
         ?subject owl:sameAs ?wsubject .
         FILTER (STRSTARTS(STR(?wsubject), "http://www.wikidata.org"))
    }
    SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}
Try it!

This works.

Simpler federated query from Survol[edit]

This returns the error message: 

Unknown error: Service URI http://vps516494.ovh.net/Survol/survol/sparql.py is not allowed

PREFIX survol: <http://www.primhillcomputers.com/survol#>
SELECT * WHERE {
    SERVICE <http://vps516494.ovh.net/Survol/survol/sparql.py> {
            SELECT ?process_id
            WHERE
            { ?url_proc survol:Handle ?process_id .
              ?url_proc rdf:type survol:CIM_Process .
            }
    }
    SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}
Try it!
