[edit] The Dublin Core Metadata Element Set
Namespace: http://purl.org/elements/1.1/ formerly dc
This is the basic vocabulary to describe Documents. Wikipedia has planned to derive some Properties from these. Some Elements like "contributor" and "creator" may automatically created by 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.
