Represents a universe of RDF statements, which at the abstract level
represents a set of graphs that make up an RDF model
- __init__(self, driver, schemaHandler=None, baseUri='')
-
Initializer for an RDF model instance. driver is an intance of
the driver used to store the statements. schemaHandler is a
reference to an object that can be used to govern operations
on the model, as typically formalized in a schema language such
as RDFS or DAML. This object can be None, disabling all such
specialized processing.
- Overrides: __init__ from class Resource
- add(self, statements)
-
Add statement(s) to the model
- addContainer(self, container, scope=None)
-
Add a container to the model. This involves adding a statement
for the container type, and a container statement for each item in
the collection.
- bind(self, object, name, scope=None)
-
Bind a Compiled Inference Object to a specific name in the Model
- checkConsistency(self)
-
Check the consistency of the entire model
- compileRil(self, expression)
-
Compile a Ril expression into a compiled object
- complete(self, subject, predicate, object, statementUri=None, scope=None, **flags)
-
Return all the statements in the model that match the given pattern.
Any combination of s, p and o can be None, and any None slot is
treated as a wildcard that matches any value in the model. A list
is returned comprising all the statement objects that match the
arguments.
flags keyword arguments map to the listed arguments with 'Flags'
append to the name. Where the value is any combination of
IGNORE_CASE and REGEX.
http://www.w3.org/TR/rdf-mt/#RDFRules [7.3 RDFS Entailment Rules]
An RDFS entailment rule (rdfs7) can be applied to 'enhance' and/or optimize this calculation
- contains(self, statement)
-
Check if a statement is in the model
- containsPattern(self, subject, predicate, object, statementUri=None, scope=None, **flags)
-
Determine if any statement matching the given criteria is in the model.
See complete() for a description of the flags keyword argument.
- exclude(self, subject, predicate, object, statementUri=None, scope=None, **flags)
-
Return all the statements in the model that DO NOT match the given pattern.
See complete() for a description of the flags keyword argument.
- extractContainer(self, uri, scope=None)
-
Build a container object from the container item relationships in the model (_1, _2, etc.).
- generateBnode(self)
-
Generates blank nodes (bnodes), AKA anonymous resources
- generateUri(self)
-
Generates URIs on the fly, e.g. for reified statements.
Do *not* use this to generate anonymous resources.
Use generateBnode instead
The default method is to generate a UUID URN,
but this can be easily overridden.
- has_key(self, name, scope=None)
-
See if the specified name is bound to the model
- isBnodeLabel(self, label)
-
Determines whether a label is a blank node
- keys(self, scope=None)
-
Get a list of bound names in the model
- lookup(self, name, scope=None)
-
Retrieve a previously bound Inference Object from the model
- remove(self, statements)
-
Remove statement(s) from the model.
- removePattern(self, subject, predicate, object, statementUri=None, scope=None, **flags)
-
Remove all statements from the model that match the specified pattern.
See complete() for a description of the flags keyword argument.
- resumeSchema(self)
- setSchemaActivity(self, value)
- size(self, scope=None)
-
Returns the number of statements in the model
- statements(self, scope=None)
-
Returns all the statments in the model.
- suspendSchema(self)
- unbind(self, name, scope=None)
-
Remove a binding from the model
