is a great example of how web services using RESTful can link
information processes that are useful for Canadian Seniors
As the article points
out, instead of simply providing an HTML interface for human readers,
the site's maintainers decided to make information available via
XML as well so that other jurisdictions (such as provinces and cities)
could include the same seniors' information in their web sites as
computer to computer linkage. And this represents the fundamental
architectural revolution of web services - the linking of information
(and other processes) as computer to
computer communication, rather than linking HTML interface for humans.

Big, public REST application:
Seniors Canada Online
Yesterday I found out
about a major government XML+HTTP (i.e. REST) web application that
has been open to the general public since October 2004 but was never
formally announced - I'm posting about it here with permission
from the federal department that's hosting it.
The Seniors Canada Online
web site is designed to provide amalgamated information for senior
citizens from all levels of government - currently it contains seniors'
information from the Canadian federal government, the
provincial and territorial governments, and the city of Brockville,
but more municipalities and NGOs will likely be joining in the future.
Instead of simply providing an HTML interface for human readers,
however, the site's maintainers decided to make information available
via XML as well so that other jurisdictions (such as provinces and
cities) could include the same seniors' information in their web
sites. In fact, since it's wide open, anyone can experiment with
using the XML data.
According to the developer,
the implementation was trivial - the REST application shares its
database and application logic with the HTML web site, so the XML
part is just a thin view written on top of all that, running in
parallel with the HTML view.
