Metadata Schemas

A metadata set consists of elements in which each element refers to a label that describes particular information about a resource. A resource here is defined as "anything that has an identity". In the context of the Document-like Information Objects, a resource could be, for example, a document, monograph, web page, project report, etc.

Here are some examples of metadata, or description of content, about resources:

• authors, titles and publishers in a catalogue for books;
• names, addresses and telephone numbers on business cards for people;
• titles, singers, lyrics, duration of the songs for CDs; and
• ingredients, nutritional information and prices on packages of food products.

A set of elements used to describe an object is called the metadata element set.
