Subject: [office] OpenDocument TC Work Call Minutes 2006-07-31

1. Dial-In, Roll Call

Nathaniel Borenstein, IBM
Yue Ma, IBM
Helen Yue, IBM
James Mason, ISO/IEC JTC1/SC34
Michael Brauer, Sun Microsystems
Lars Oppermann, Sun Microsystems

2. Minutes Approval, Action Items

This is the first work call after a period of coordination calls only. 
there are no past minutes and action items.

3. SC status

Formula SC (DavidW)
recently posted comprehensive status report on list.
there was discussion about namespacing formulas and functions. We 
decided to use DNS-like prefixes to qualify names rather than using XML 
qnames inside attribute values which is not viewed as a good design.
The formula SC is currently working on the function definitions. We 
could greatly accelerate this process, if more people would help to 
write function definitions. We are asking everyone who could spare a few 
cycles on such work to help us with this.
We are looking at ~300 functions that have to be defined for our first 
version. These are a union of the functions provided in the most popular 
spreadsheet applications and are thus a foundation for interoperability.

(Michael) should the TC review (and maybe approve) the syntax 
specification since that is now finished?
(DavidW) There are a few issues remaining with naming and error 
handling. We plan to have those resolved by next Thursday. We would 
submit that version to the TC for review.

(Lars) how is the different calculation behavior of different 
applications handled in the specification? E.g. automatic conversion of 
text-content into numbers...
(DavidW) Especially automatic conversions are a very fragile feature, as 
they tend to break with different locales (number formatting). We are 
investigating to define 'calculation-settings' where such behavior can 
be defined but there will be some documents, that are using undefined 
implicit conversions in a way that they might not be interoperable.

(Michael) what is the current time-line?
(DavidW) we were aiming at finishing by September. Function definitions 
are a lot of work and we are needing more people to work at those in 
order to speed things up. Otherwise we will slip into October.

(Michael) we are currently planning ODF 1.2 for mid-2007. So it looks 
like we will have a stable formula specification for that version for sure.

(Michael) will formulas be a separate document or should the eventually 
be included into the main specification?
(DavidW) I think it makes sense to keep them separated.
(Michael) I concur, and it gives us more flexibility when planning releases
Are there any requirements from the formula SC for the main 
specification of ODF?
(David) some minor changes/additions will be needed, e.g. description of 
the equal-sign, calculation-settings (for text-number-conversion)

(Michael) all implementor should indicate if they are planning to 
propose additions to 1.2 as early as possible.
I will also ask SC chairs to state their deliverables for 1.2 in order 
to finalize the roadmap for 1.2

(Gary) is it possible to have a public review of the formula 
specification without going though an OASIS voting afterwards
(Michael) yes, but I will re-check with OASIS (Mary) how we can best 
handle this
