Recently, people have asked me for a list of sections that could be spun 
off from HTML5 into their own specs, with other editors, to lighten the 
workload for taking HTML5 to REC.

This is the list of sections that could be spun off from the HTML5 spec as 
it stands today, ordered in descending effort-to-benefit ratio (i.e. the 
more helpful it would be to spin off the section, the earlier it is in the 
list; the lower it is in the list, the more it would delay the overall 
effort). The higher something is in this list, the most helpful it would 
be for speeding up the process.

The time estimates are intended to be accurate (neither conservative nor 
optimistic) and assume a competent and experienced editor and no unusually 
large unforseen problems. Time for forging relationships with browser 
vendors, setting up the infrastructure to edit a spec and track comments, 
and getting up to speed with the knowledge needed is not taken into 
account as it depends on who is the editor. In all cases, editors will 
also need to beable to perform or commission studies using techniques such 
as instrumenting Web browsers and scanning Web content.

For background on what sections we've tried to split out before, and what 
basic skills and abilities an editor really should aspire to have in 
addition to those listed below, please see this e-mail from last month:

   http://lists.w3.org/Archives/Public/public-html/2008Sep/0004.html


1. HTML5 Rendering and UA behavior

attributes, and DOM APIs; recommended rendering dimensions and basic user 
interface conventions of form controls; recommended default rendering 
rules and default style sheet for HTML.

browsers, researching authoring trends. Access to multiple browsers 
necessary, multiple platforms a plus.

 - 24 months at 5h/week responding to further feedback


2. Interaction events

Scope: defining the relationship between user interaction (clicks, mouse 
movements, key presses, etc) and DOM2 Events, hit testing, and documenting 
any special behavior relating to HTML features.

Skills and knowledge needed: JS, DOM, HTML, reverse-engineering browsers. 
Access to multiple browsers and platforms necessary.

Estimated workload:
 - 6 months at 40h/week researching, reverse engineering and specifying
 - 4 months at 20h/week responding to immediate feedback
 - 12 months at 5h/week responding to further feedback
 - 24 months at 1h/week responding to further feedback


3. 3D Canvas

Scope: defining a new API for 3D graphics.

Skills and knowledge needed: 3D graphics, JS, DOM, HTML (in particular, 
experience with the 2D canvas API), API design, reverse-engineering 
browsers. Access to multiple browsers a plus.

Estimated workload:
 - 3 months at 20h/week researching and working with browser vendors and 
   Web authors to establish requirements, needs, and goals
 - 2 months at 40h/week to design and specify a first draft API
 - 6 months at 20h/week to respond to feedback and work with browser 
   vendors and Web authors to update proposed API
 - 12 months at 5h/week to test and reverse-engineer implementations and 
   work with browser vendors to update the implementations and the spec 
   accordingly
 - 24 months at 2h/week responding to further feedback


4. UndoManager

Scope: defining the undo/redo API for Web applications (including 
contentEditable editors).

Skills and knowledge needed: JS, DOM, HTML, API design, 
reverse-engineering browsers. Access to multiple browsers a plus.

Estimated workload:
 - 3 months at 40h/week researching, reverse engineering and specifying
 - 2 months at 5h/week responding to immediate feedback
 - 5 months at 1h/week responding to further feedback
 - 12 months at 5h/week to test and reverse-engineer implementations and 
   work with browser vendors to update the implementations and the spec 
   accordingly
 - 24 months at 1h/week responding to further feedback


5. Stylesheet DOM

Scope: specifying the alternative stylesheet API.

Skills and knowledge needed: CSS, HTML, JS, DOM, API design, 
reverse-engineering browsers. Access to multiple browsers necessary.

Estimated workload:
 - 1 month at 40h/week researching, reverse engineering, designing, and 
   specifying
 - 1 month at 5h/week responding to immediate feedback
 - 24 months at 1h/week responding to further feedback


6. URL

Scope: defining error handling for URLs, handling of base URLs, and 
resolving URLs to base URLs. Updating the URI and IRI specifications to 
reflect actual implementations.

Skills and knowledge needed: IRI, HTML, JS, DOM, reverse-engineering 
browsers. Access to multiple browsers necessary.

Estimated workload:
 - 1-6 months at 40h/week researching, reverse engineering, designing, and 
   specifying, depending on the approach taken
 - 1-6 month at 5h/week responding to immediate feedback
 - 24 months at 1h/week responding to further feedback


7. Common DOM interfaces

Scope: HTMLCollection, DOMTokenList, DOMStringMap, and related 
definitions.

Skills and knowledge needed: DOM, JS, HTML, reverse-engineering browsers, 
API design. Access to multiple browsers necessary.

Estimated workload:
 - 2 months at 30h/week researching, reverse engineering, designing, and 
   specifying
 - 12 months 5h/week coordinating with other specs and responding to 
   feedback
 - 24 months 1h/week responding to further feedback


8. Content-Type handling and content sniffing

Scope: Defining the various ways that browsers are to handle bogus or 
potentially incorrect Content-Type values, how to parse Content-Type 
values (including error handling), how to do content sniffing, etc.

Skills and knowledge needed: HTTP, MIME, HTML, character encodings, good 
understanding of a variety of common binary and text formats used on the 
Web, MIME, reverse-engineering browsers. Access to multiple browsers and 
platforms necessary.

Estimated workload:
 - 1 month at 40h/week integrating existing text
 - 3 months at 20h/week researching, reverse engineering,
   soliciting feedback, and responding to feedback
 - 6 months at 10h/week responding to feedback
 - 24 months at 2h/week responding to further feedback


9. 2D Canvas

Scope: correcting errors and adding new features to the 2D graphics API.

Splitting this out would probably slow down HTML5 itself by a few weeks.

Skills and knowledge needed: 2D graphics, JS, DOM, HTML (in particular, 
experience with the 2D canvas API), API design, reverse-engineering 
browsers. Access to multiple browsers and platforms necessary. Ability to 
tactfully say "no" a lot a definite plus.

 - 24 months at 20h/week researching, reverse engineering, designing, 
   specifying, and responding to feedback
 - 24 months at 2h/week responding to further feedback


10. Platform Core

Scope: browsing contexts, event loops, navigation, fetching, origin, 
scripting contexts, the Window object, etc.

Splitting this out of HTML5 would probably delay HTML5 by up to a year, 
and would introduce a dependency from HTML5 to this spec.

Skills and knowledge needed: DOM, JS, HTML, SVG, API design, 
reverse-engineering browsers. Access to multiple browsers and platforms 
necessary.

Estimated workload:
 - 4 months at 40h/week extracting existing text from HTML5
 - 12 months at 40h/week reverse-engineering and specifying

 - 24 months at 5h/week responding to feedback


If anybody wants to volunteer for one of these sections, please let me 
know. I would be more than happy to help you get set up.

Cheers,
