literals

Every use of a predicate inside a node: the context path where the use sits and its polarity. Heads appear with the head context, so readers are found by excluding it. A literals row proves that the predicate is mentioned there. It proves nothing about whether the literal holds or the rule that holds it fires.

Fields

From the live dictionary on the reference fixture:

field
node
context
predicate
polarity
package
path

Example

One meaningful query on the reference fixture (6 rows):

LawQL

from l in literals where l.predicate == "urn:law:demo:lawqlbase#eligible" select l.node as reader, l.context as context
