--------

To initialise the database, first open a store:

import sqltriples
store = sqltriples.open(dbname, dbmodulename)

Then, use the init method on the TripleStore object as follows:

store.init()
store.commit()

See the attributes of the different adapter classes for details of the table and
sequence employed.

To remove the triple store objects from the database, use the delete method on
the TripleStore object as follows:

store.delete()
store.commit()

NOTE: The statements sent to the database system can be configured, but this
NOTE: should be made convenient in future releases.

Submodules
  • Adapters: Database-specific adapter classes.
  • Query: Database querying classes.
  • Store: RDF triple store classes.
  • Types: Special data types inheriting from the unicode type in order to provide interoperability with rdflib.

Function Summary
  open(database_name, database_module_name, adapter, table_name, sequence_name, debug, **kw)
Open a triple store using either a connection identified by 'database_name' and using the given 'database_module_name' along with other keyword arguments, or using the given 'adapter' object.

Function Details

open(database_name=None, database_module_name=None, adapter=None, table_name=None, sequence_name=None, debug=0, **kw)

Open a triple store using either a connection identified by 'database_name'
and using the given 'database_module_name' along with other keyword
arguments, or using the given 'adapter' object. If the optional 'table_name'
and 'sequence_name' are provided, override the default settings in the
TripleStore class in order to access stored information in the database. The
optional 'debug' parameter (set to false by default) can be used to show the
working of the triple store.
