Linking XML Documents and Resources

A link is directional. That is it points from on location in a document to another location in a (possibly different) document. It might even point to a (non XML) ressource such as a movie, picture, sound file etc.

Resources

In order to be able to link to a ressource, the resource must have a name. This name is usually a URI (uniform resource identifier).

URI

Two types of URIs:
  • resource is found by its location
    For example http://www.adp-gmbh.ch/xml/index.html.
  • resource is found by its name (for example: FPI)

ID

ID is a special type of attributes.
