I have been following the w3c discussion at
have read the use cases at
I think such as feature is very useful as web applications become more
prevalent and especially with the interest in web operating systems. The
standardisation and simplification to promote growth in this area.
I would like to get involved and was wondering what the current status is of
For my part, as a hobbyist web developer, I have suggestions as to how I'd
like to use this feature and have written a framework (
http://code.google.com/p/htmlcomponentframework/) and an article (
of how the functionality could be exposed.
With time I would like to improve this and have something similar integrated
within the browser; for now it depends on div and iframe elements whereas
ideally I'd like to be able to define new elements and use them within the
HTML body. The usage, though, is essentially the same:
Within the parent (hosting) page:
- Add elements to the HTML head to define the components that are to be
- Add elements to the HTML body (either by markup or DOM manipulation)
where the components are to be shown.
- Integrate code with the components by: registering event handlers with
them, firing events at them, and altering their exposed DOM.
To create a component:
- Add elements to the HTML head to define: the component's exposed DOM,
the events it can receive, the events it can raise.
The implications of something like this reach further than just simplifying
the modularisation of web applications. For example, it would be possible
1. Define an address book component's contract.
2. Expose a component fulfilling the contract from online address book
3. Consume my preferred address book application provider from within an
online email client or social network site by pointing them at the
component's URL and using oAuth to authorise access.
4. From within the consuming web application select and edit my contacts
using my actual address book application provider that I am familiar with.
