Re: [ddlm-group] DDLm aliases (subject changed). .. .. .. .. .. .... .. .. .

Dear James,

There seems to be general agreement on Herbert's version of the DDLm changes to the alias and xref items given at the url in the email below, but we should have a vote to formally adopt these changes in the draft DDLm that we are evaluating.  Eventually the fully revised DDLm will have to be voted on by COMCIFS, but at this stage we need to know that the DDLm discussion group is on board so that we can start adapting DDLm CIF dictionaries.  In my case, this will require changes to the majority of items in the dictionary and I want to make sure that we all agree on how aliases should be presented before I start making these changes.

Can you please call for a vote.

These messages are getting too long.  I have posted the current
best draft of what I will be using for my own work at


which should be considered a preliminary proposal to COMCIFs
in support of the development of a DDLm dictionary for
imgCIF along with a DDLm dictionary for the portion of the
mmCIF dictionary needed to support imgCIF.

I hope to have practical code using this to demonstrate in Madrid,
when we can discuss it face-to-face.

I think the original COMCIFS decision of a global
name space was a wise choice for the major applications of
CIF, and would suggest we stick to it for DDLm.
For the record, lest it be obscured by the volume of rhetoric, none of 
the name space issues I have raised in this discussion of DDLm aliases 
should be construed as advocacy for COMCIFS changing policy on naming, 
prefixes, etc..  The introduction of DDLm is no justification for such a 
disruptive move.  All I ask the group to consider is whether DDLm should 
provide for cases where COMCIFS policy is not observed.
