Usage: python %prog --output_directory_base <path to desired deployment directory> [options]

  Deploys packaged schemas to <output_directory_base>.

  Sets "id" field of deployed schemas appropriately based on <url_base>.

  Example usage:

    python %prog --output_directory_base /tmp/irods_schemas

    This will create, if necessary, /tmp/irods_schemas and /tmp/irods_schemas/v{SCHEMA_VERSION}, then populate the latter with copies of the schema files currently found in {SCHEMAS_DIR}. The schema copies will have their "id" fields updated to reflect their new locations (e.g. "server_config.json" will have "id" field "file:///tmp/irods_schemas/v{SCHEMA_VERSION}/server_config.json#".

    To have an iRODS installation validate its configuration files against this local deployment, set the iRODS "schema_validation_base_uri" (found in "/etc/irods/server_config.json" or fed into the prompt during setup) to "file:///tmp/irods_schemas".

    Make sure that the Linux account running iRODS has read access to the deployed schemas.
