COMCIFS report 2009
In the second half of 2009, COMCIFS formed a DDLm working group to
thrash out remaining issues with the new dictionary (“DDLm”)
framework. As the year was drawing to a close, the final touches were
being put on to one component of this framework, an updated CIF syntax
specification, dubbed 'CIF2'. This has been distributed to the
community for comment prior to final adoption by COMCIFS. The working
group's attention has now moved on to discussion of DDLm itself.
New dictionaries continue to be developed. A draft small angle
scattering dictionary (sasCIF) is at an advanced stage, and an updated
symmetry dictionary is also nearing completion. A proposed dictionary for
expressing restraints and constraints in single-crystal refinements is
currently under review by the core dictionary maintenance group.
Recognising that the procedure for adding definitions to CIF
dictionaries can be impenetrable and discouraging for non-CIF experts,
COMCIFS has developed and tested a streamlined fast-track procedure
for adding single definitions to a dictionary. Under this procedure,
the relevant dictionary working group has 6 weeks to comment and
develop the definition, following which COMCIFS has a further 6 weeks
to discuss and accept the proposal. An announcement of a web portal
for submission of such fast-track proposals should be expected in the
near future.
