subject	Re: [RAI] MPEG liaison statements received


FYI (responding to the comment about the approval process steps):  If
you count producing a CD ballot text as being the first step, I would
say that there are basically three main steps in the current ISO/IEC
approval process – where the other two are the production of DIS and
FDIS. (For those who may have been familiar with the way things were a
couple years ago, the DIS stage was previously called an FCD.) After
an FDIS is produced, there are no changes (other than such things as
typo fixes or rephrasing a garbled sentence or two) – except, of
course, by issuing subsequent amendments and corrigenda. There is a
ballot of an FDIS before it is considered a fully-approved standard,
but the only outcome of that ballot is "Yes" or "No", not "Let's
change section 7" – and I have personally never witnessed a "No"
outcome on such a ballot. So, for practical purposes, an FDIS is the
final standard.

The time between issuing a CD and issuing an FDIS takes a minimum of
about 9 months, but would more typically take about one year (or
longer).

Best regards,

Gary Sullivan
