A Work is an individual creation, for example a literary opus, which can be available in various editions, e.g. as a pocket edition, as part of a series of collected works, as a theatrical performance or as an audio book. An Edition is always a particular edition of a work. To describe a Work, TextGrid offers Work Objects: These are metadata-only Objects that contain work-specific metadata such as the uniform title, the date of creation or keywords describing the Work. By the time of publication, every Edition Object must be linked to a Work Object.
