The URL Subscription Architecture (URLSA) is an open system for subscribing to frequently updated digital content on the web, such as blogs, news stories, and private conversations. It was designed as an alternative to RSS that supports social subscribing, private subscriptions, and rich content.
URLSA users can subscribe themselves and other users to the URL of some content and, once subscribed, are notified when the content at that URL is updated. Users typically maintain a list of subscriptions to everything from news stories to conversations. The architecture allows users to generate private content, such as a conversation or a photo album, on the fly and subscribe other users to it. The fact that URLSA is a content-less architecture, that users subscribe to the URL of the content rather than the content itself, means that virtually any type of content that is addressable by a URL can be made subscribable.

Famous quotes containing the words subscription and/or architecture:
“The mode of founding a college is, commonly, to get up a subscription of dollars and cents, and then, following blindly the principles of a division of labor to its extreme,—a principle which should never be followed but with circumspection,—to call in a contractor who makes this a subject of speculation,... and for these oversights successive generations have to pay.”
—Henry David Thoreau (1817–1862)
“Polarized light showed the secret architecture of bodies; and when the second-sight of the mind is opened, now one color or form or gesture, and now another, has a pungency, as if a more interior ray had been emitted, disclosing its deep holdings in the frame of things.”
—Ralph Waldo Emerson (1803–1882)
