Link awareness

Link awareness is defined as the ability to discover, view, search and update global hyperlink information about any resource with a URL on the World Wide Web. This global link information is a shared information resource.

Implementing link awareness is difficult. In practice, an implementation only approximates link awareness. There are at least two qualitative axes on which we can classify these implementations.

  • Breadth of coverage: The number and type of interlinked documents covered.
  • Liveness: The ability (or lack thereof) to update the link information on the fly.

Implementation examples
  • Most WikiWiki implementations support link awareness within the scope of the documents that they host. Their breadth of coverage (insofar as link information is concerned) is narrow. A wiki, however, is very live (and indeed, liveness, is its raison d'etre).
  • Google supports link awareness through its web interface. (You type in a query of the form link:<URL>.) Google's breadth is impressive (it covers a lot of interlinked documents), but it is a far cry from live (it can take months before Google indexes a newly created document).

gollark: What an excellent code guessing entry. Thanks for showing me it.
gollark: That's only 0.00011574074 Hz, totally doable.

gollark: Or they may just have renamed it in the API and not real life™.
