Query Client

Query Client (query.cmd/query.sh)

The query client also supports specifying a query file for easier handling of multiline queries:

query.cmd -qf myQueryFile.obl

query.cmd -queryFile myQueryFile.obl

A query file contains a query (as you would type one in the Web console):

:- prefix b = "http://www.ontoprise.com/ontologies#".

:- module = b#ontowebtravel.

:- default prefix = "http://www.ontoprise.com/ontologies/ontowebtravel#".

?- ?X:?Y.

When you execute the query file you get your results as usual (this example uses the "travel" example ontology):

X Y

----------

<http://www.ontoprise.com/ontologies/ontowebtravel#h2> <http://www.ontoprise.com/ontologies/ontowebtravel#Hotel>

<http://www.ontoprise.com/ontologies/ontowebtravel#john> <http://www.ontoprise.com/ontologies/ontowebtravel#Customer>

<http://www.ontoprise.com/ontologies/ontowebtravel#d2> <http://www.ontoprise.com/ontologies/ontowebtravel#Date>

<http://www.ontoprise.com/ontologies/ontowebtravel#d3> <http://www.ontoprise.com/ontologies/ontowebtravel#Date>

<http://www.ontoprise.com/ontologies/ontowebtravel#d1> <http://www.ontoprise.com/ontologies/ontowebtravel#Date>

<http://www.ontoprise.com/ontologies/ontowebtravel#washington> <http://www.ontoprise.com/ontologies/ontowebtravel#City>

<http://www.ontoprise.com/ontologies/ontowebtravel#madrid> <http://www.ontoprise.com/ontologies/ontowebtravel#City>

<http://www.ontoprise.com/ontologies/ontowebtravel#newyork> <http://www.ontoprise.com/ontologies/ontowebtravel#City>

<http://www.ontoprise.com/ontologies/ontowebtravel#t1> <http://www.ontoprise.com/ontologies/ontowebtravel#Transport>

<http://www.ontoprise.com/ontologies/ontowebtravel#h1> <http://www.ontoprise.com/ontologies/ontowebtravel#Hotel>

<http://www.ontoprise.com/ontologies/ontowebtravel#h2> <http://www.ontoprise.com/ontologies/ontowebtravel#Location>

<http://www.ontoprise.com/ontologies/ontowebtravel#washington> <http://www.ontoprise.com/ontologies/ontowebtravel#Location>

<http://www.ontoprise.com/ontologies/ontowebtravel#madrid> <http://www.ontoprise.com/ontologies/ontowebtravel#Location>

<http://www.ontoprise.com/ontologies/ontowebtravel#newyork> <http://www.ontoprise.com/ontologies/ontowebtravel#Location>

<http://www.ontoprise.com/ontologies/ontowebtravel#h1> <http://www.ontoprise.com/ontologies/ontowebtravel#Location>

But it is also possible to abbreviate the namespace terms with the namespaces given in the query text:

query.cmd -queryFile myQueryFile.obl -abbreviateNamespaces

In this case you get

X Y

----------

h2 Hotel

john Customer

d2 Date

d3 Date

d1 Date

washington City

madrid City

newyork City

t1 Transport

h1 Hotel

h2 Location

washington Location

madrid Location

newyork Location

h1 Location

If you additionally specify the "-formatting" option then the result will be formatted to be easily readable. However, in this case, the whole query will be executed before the result will be printed. The result looks like this:

X Y
