Utility

imeji implements a migration utility. This is based on SPARQL update (specifications). The SPARQL query should be written in a file called "migration.txt". This file should be stored in the jena tdb home directory (see Imeji_properties, property "imeji.tdb.path"). The content of this file is reported on this page for each migration.

From 1.0.0.0 to 1.1.0.1

• Note: The migration utility is not available for 1.1.0.0. Therefore you need to use 1.1.0.1 to upgrade from 1.0.0.0.
• migration.txt:
