PREPARATION OF WORKING DRAFT

3.1 WD Template:

close ACTION-33

<trackbot> ACTION-33 Start the template of the document closed

Raphael has prepared a template

<raphael> http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-reqs/

scribe: will check in html files
... will send reminder on who is responsible for which section

Erik suggests to add hard deadlines to the sections, so we can go towards our milestones

Raphael suggests that a week per sections may be do-able because it's a straight copy from the wiki

Erik agrees

scribe: asks, when we want the document to be posted/published, so we can work backwards towards deadlines

Raphael says that our first working draft was due by end of January

scribe: we should have it all ready by mid march

<erik> +1

scribe: mostly 2-3 teleconfs to finalize
... will send reminder email

Conrad will post more comments

close ACTION-41

<trackbot> ACTION-41 Rewrite Syntax in ABNF based on RFC4234 closed

Yves has posted a ABNF

Michael suggested to write the generic rule at the top and go into more detail further down

Yves reckons this is a matter of taste

Yves will add more details to link it to the original URI spec

Raphael thinks we decided to have either a named fragment or a combination of the others

<Gui> http://www.w3.org/2008/WebVideo/Fragments/wiki/Syntax#Formal_Grammar

scribe: this is not represented right now

Yves thinks this is hard to capture in the production rule, and better to describe in text

Let's give this a try and see what comments we get back

Raphael & Silvia agree
