Triptych Project

Three Proposals for HTML

The Triptych Project is an effort to add three HTML features to all browsers:

PUT, PATCH, and DELETE methods<br>Buttons actions without forms<br>Partial page replacement

These relatively small changes make HTML significantly more expressive, enabling far more web applications to be built with pure hypertext.

For instance, this HTML represents a common "edit post" flow, like you might find on a message board or social site, no scripting required. See the examples page for a full explanation.

form action="/posts/123" method="PUT">

textarea name="content">I read the news today; oh boy.textarea><br>button>Savebutton>

button action="/posts/123" method="GET">Cancelbutton><br>button action="/posts/123/draft" method="PUT">Save Draftbutton><br>button action="/posts/123" method="DELETE">Delete Postbutton><br>form>

Status

Now

Currently planning the Chromium implementation and the required changes to the web platform tests.
