[mpeg-OTspec] Re: A path through the thicket

[Leonardo Chiariglione]

Vladimir,

 

I believe we agreed to defer the discussions related to mandatory/optional
nature of any tag/attribute until after we have complete functional
descriptions of all XML tags we believe would be necessary / useful for
Composite Fonts spec. 

This is very much the MPEG approach. First we develop the tools and then we
define profiles, i.e. groups of tools (groups of XML tags, in this case)
that are useful for a given purpose.

Terms we do not use are "mandatory" and "optional". In the MPEG language
everything is mandatory in a profile. The point is that the profile itself
may not be mandatory because we do not want to impose on all users the use
of all tools.

Ken,

 

Thank you very much for putting together the draft. I believe we agreed to
defer the discussions related to mandatory/optional nature of any
tag/attribute until after we have complete functional descriptions of all
XML tags we believe would be necessary / useful for Composite Fonts spec. 

 

For convenience and easy access I put the document into the Files section of
the AHG
http://groups.yahoo.com/group/mpeg-OTspec/files/CompositeFont-11242009.pdf.

 

I would like to ask the AHG members to review the list of tags and
attributes Ken prepared and to provide your input - any corrections and
proposals for additional tags/attributes that you believe would be needed
are very much appreciated. Once we complete this list, we will review and
discuss the potential impact /cost / complexity of implementation for each
element of the spec and make our final determination of the mandatory vs.
optional status for each element. For now - please disregard this in the
current draft and review the spec from the functional point of view.

 

Thank you and Happy Thanksgiving!

Vladimir

Vladimir and others,

Please see the attached file, which I hope may represent a start at 
creating a working draft of the specification.
