 The ICE-D web server is an example of an analysis layer application. Mostly, the purpose of this application is to display information to a user via a web browser, but there are a couple of tricks embedded in the web page that allow one to also use this application to get information in a form that can be easily used by software. This is explained [[pluginto:webpage_scraping|here]].  The ICE-D web server is an example of an analysis layer application.
