Tobias Schlitt has posted about a new component for the eZ components (PHP based) system he develops for - a WebDAV module.
Starting by the end of August we spent almost whole September full-time on designing and implementing this component. The goal was to design a flexible WebDAV server component, which can be used to edit whatever data source on an HTTP server through the WebDAV extension of the protocol, with the full lot of concerns in mind.
Included in the post is an image showing the architecture of the component and a mention that, if you're attending this year's International PHP Conference (2007), you'll be able to see it in action.
