Taxonomy: assign taxonomy concepts to media assets
Over the next days, Contentful is rolling out the ability to assign taxonomy concepts to media assets, return taxonomy information on assets, query assets based on taxonomy concepts in the Content Management API and Content Delivery APIs to all customers.
Media assets do not need content type validations to assign a taxonomy concept. All taxonomy concepts created within the organization are available for assignment to an asset.
In the media asset editor, navigate to the “Taxonomy” tab and select concepts to assign to that media asset.
