Dublin Core schema
From The Glossary of Digital Photography
More properly called the Dublin Core Metadata Element Set. This schema was created at a workshop in Dublin, Ohio, in 1995. It is a set of fifteen different elements used to describe digital assets. The fifteen elements are: contributor, coverage, creator, date, description, format, identifier, language, publisher, relation, rights, source, subject, title, and type. The Dublin Core not only lists the elements but also defines what each of them means. Digital images use many of these elements to describe an image; they are stored as metadata in the image itself. The information can be added in a program such as Photoshop. See also metadata
