Meta-donnée

Article dans la documentation

"Assets can have meta-data attached to them, and that meta-data is used to aggregate similar assets together in searches or as published content. One way to do this in the example above is to tag and categorize stories so they can be found more easily by users.

For example, meeting metadata is composed of fields such as Meeting Name, Date, Time, Location, Description, and Participants. This is a generic set of fields that go together and that you’d want to use as a group. You can create as many of these as you want.

When a user assigns a document type to a document, the user is required to fill out the fields defined by the metadata set of the document type. This encourages users not to forget to enter important information about their documents."

Les métadonnées sont des des données caractérisant une donnée (objet, contenu, document) liferay.
