[edit] The Dublin Core Metadata Element Set

These is the basic vocalbulary to describe Documents. Wikipedia is planned to derive some Properties from these ones. Some Elements like "contributor" and "creator" may automatically created by the wikipedia (think of the history of this document); "publisher" is a fixed value "Wikipedia Foundation Inc.". Others like "description" are not explicitly planned in the current design of Wikipedia. The "subject" of an article is mostly the header or (true) title of it.

[edit] Types

Namespace: http://purl.org/dc/dcmitype/ formerly dcc

Types are not implemented as Attributes or Properties. Instead there are Classes and in that Case Articles. A Article can derive from this Types.

• Collection
• Dataset

  May be used for Database Records or maybe defining Enumerated Datatypes.

  see also: Wikidata

• Event

  This is used when the article is about things, that happened (or will happen) in history.

  (ie. "The coronation of king william III", but not the Article "William III")

• Image

  Is either a Moving Image or a Still Image.

• Interactice Resource

  Java Appletts, Flash, or simmilar interactive content. Not currently used in Wikipedia.

• Moving Image

  Used for Videos. Not currently used in Wikipedia.

• Physical Object

  Meaning that the article is about a Physical Object. This can mean Buildings, Persons and other physical Objects. Note that Building and Person derive from Physical Object and therefore no need to define explicit.

• Service

  Means a System with additional Services to the user. Examples are a Bookshop, Onlinebanking, or - to keep the context - the Specialpages in the Wikipedia.

• Software

  Defines an Article about a specific Software Product.

• Sound

  Defines a Audio-File. This may be useful in the Wikiquote and Wiktionary Project.

• Still Image

  Used for defining the Type of an Image. All uploaded Pictures should derive automatically from this type.

• Text

  All Articles are a Text. The derivation from this Type might become implicit.
