Detailed Description

Model filter that makes working with NRL data simpler.

The NRLModel enforces NRL cardinality rules. That means predicates with a cardinality of maximum 1 are always udpated while statements that define predicates with a maximum cardinality bigger than 1 are rejected once the maximum is reached (future versions might remove an earlier defined statement based on the time the old statements were added).

Thus, at the moment NRLModel is mostly usable for handling properties with a maximum cardinality of 1.

NRLModel also provides automatic query prefix expansion and named graph creation and removal with automatic metadata graph handling.

THE API AND EVEN THE COMPLETE CLASS IS SUBJECT TO CHANGE!

Member Function Documentation

void Soprano::NRLModel::setIgnoreContext

(

bool

b

)

When enforcing the NRL cardinality rules NRLModel can either ignore the context of statements or treat different contexts as separate sets, each resetting the cardinality.

Parameters:

b

If true (the default) NRLModel does ignore the context when enforcing rules. If false the NRL rules can be violated across contexts.

By default contexts are ignored.

ignoreContext()

bool Soprano::NRLModel::ignoreContext

(

)

const

Returns:

true if contexts should be ignored when enforcing NRL rules.
