The toolkit is comprised of a series of Java utilities that can be are invoked from the command line, and is packaged as a jar file that must be present in the environment where the commands are executed. Only users with administrator privileges can issue data management commands; they should be always tested before applying in a production environment, as they bypass regular data validity controls and may result in non-conformant data.

An ontology release is in turn packaged with a general eagle-i software release. As part of the software upgrade procedure, the eagle-i node system administrator must run the data-migration.sh script, which results in the necessary data changes being performed to reflect the new ontology. Internally, this script invokes various data management commands according to the requirements of the particular ontology release (typically only ChangeObject and ChangePredicate are requiredinvoked). Hence, in the general case, a system administrator does need not need to worry about executing individual commands.

If a system administrator upgrades to a non-contiguous release (e.g. from 1.7MS1 to 1.7MS4), applying the regular data migration procedure would miss some of the necessary data changes. The eagle-i team can produce a zip file with cumulative data migration tables (currently upon request). The To apply the cumulative tables, the directory where this zip is expanded is needs to be provided as a parameter to the data migration script, for example:

From a terminal window, commands are may be invoked as:

java -cp ./eagle-i-datamanagement.jar org.eaglei.datatools.datamanagement.command.[Command] [parameters]
