LDPath

Is it possible to use a double filter?
Something like: I want resources that are Person union with resources that are organization?
@filter rdf:type is foaf:Person 
@filetr rdf:type is org:OrganizationalUnit
and if yes what is the correct syntax?
thank you
Alex

Hi Alex,

LDPath allows only one @filter statement.

I think you are looking for the following:
@filter rdf:type is foaf:Person | rdf:type is org:OrganizationalUnit

This will match both ex:foo and ex:bar:
ex:foo a foaf:Person.
ex:bar a org:OrganizationalUnit

Generally speaking, you can use any LDPath TEST [1] within the @filter
statement.

Best,
Jakob
