Custom Metadata Validation Utility
Effective in version 10.2.2, you can use a stand-alone Java-based Validation Command Line Utility to validate the syntax and semantics of custom metadata that you want to ingest in the catalog. Custom metadata represents metadata that you want to ingest from custom data sources for which Enterprise Data Catalog does not provide a resource.
For more information about using the utility, see the KB article
How To: Validate Custom Metadata Before Ingesting it in the Catalog. Contact Informatica Global Customer Support for instructions to download the utility.
