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

I vote in favour.

I recognize that DDLm is a document in the process of development and all we are doing is adding (and modifying) a part so that we know what the document says at this time.  This does not preclude further changes later (including removing the tag_sets if we find the don't work though Herbert will probably insist that once something is in the draft the most we can do is deprecate it).  However since it is a document under development and we need to know whether there are serious objections so that we can move forward in testing it.

I also assume that some editorial work may be needed on these new features, but the tags and their functions will have been established.

I personally will not be interested in the tag_sets, but I can make good use of the xref features.

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.
