AI4 Metadata utilities

Metadata utilities for the AI4OS hub data science applications.

The AI4OS hub data science applications use metadata to describe the data sources, models, and other resources. The metadata is used to validate the resources and to provide information to the users.

Installation

The metadata utilities can be installed using pip:

$ pip install ai4-metadata

Usage

Metadata validation

The metadata utilities provide a command-line interface (CLI) tool ai4-metadata-validate that can be used to validate the metadata files. The CLI tool accepts the metadata files as input parameters.

$ ai4-metadata-validate instances/sample-v2.mods.json

Different metadata versions can be specified, either by using the --metadata-version or by providing the metadata schema file.

$ ai4-metadata-validate --metadata-version 2.0.0 instances/sample-v2.mods.json
$ ai4-metadata-validate --schema schemata/ai4-apps-v2.0.0.json instances/sample-v2.mods.json

Metadata migration

The metadata utilities provide a command-line interface (CLI) tool ai4-metadata-migrate that can be used to migrate the metadata files from V1 to latest V2.

$ ai4-metadata-migrate instances/sample-v1.mods.json

To save the output, use the --output option.

$ ai4-metadata-migrate --output sample-v2.mods.json instances/sample-v1.mods.json

Please review the changes, as the metadata migration is not complete, and manual steps are needed.
