Dear COMCIFS members and observers, I'm attaching below a draft annual report to the IUCr executive for 2008. If anybody thinks I've missed something important, please let me know as soon as possible as the deadline is tomorrow (24th May). James. ===================== COMCIFS report 2008 The central event for COMCIFS this year was the Osaka congress, where two closed meetings and one microsymposium were held. New standards for writing CIF dictionaries (DDLm and dREL) were accepted in draft form at the meeting, subject to some technical refinements. DDLm represents a merging and enhancement of the original dictionary languages (DDL1 and DDL2). The new standards will, among other things, permit more modularity in dictionary construction and allow mathematical relationships between CIF data items to be expressed in a way that permits fully automated calculation of derived values. imgCIF and the associated Crystallographic Binary Format (CBF) once again saw significant activity in 2008, including roundtable technical discussions with manufacturers and software developers during the Osaka congress. CBF is seeing increasing takeup, with manufacturers providing or developing CBF support for their detectors now including Pilatus, ADSC, Rayonix and Rigaku. Software support for CBF is also improving, with MOSFLM, ADXV and XDS all supporting CBF input. Following work at a number of laboratories this year, programming libraries for CBF support now exist in all major programming languages used in handling diffraction images. While technical development has been the focus of activity during the year, dictionaries also continue to be maintained and upgraded. An updated core CIF dictionary (version 2.4) was released in April, representing the culmination of several years' work. Following the publication of Volume A1 of International Tables, G. Madariaga is leading a group which will resume work on updating and expanding the symmetry CIF dictionary to include the information in the new volume. As other scientific disciplines and organisations begin to tackle the problem of data portability and archiving, interoperability of CIF with other data frameworks is becoming important. NeXuS is a framework for raw data storage which has seen broad adoption in X-ray and neutron facilities. Working links with the NeXuS community were established this year, including a presentation to the NeXuS advisory committee (the equivalent of COMCIFS). Discussions on how best to interoperate are ongoing. COMCIFS have also established a working group to explore how CIF, and particularly mmCIF, might interact with the Open Biomedical Ontologies project (OBO), which aims to codify concepts and relationships in biological and medical fields. The Osaka meeting also saw a changing of the guard, with N. Spadaccini and myself replacing outgoing members H. Berman, S. R. Hall, G. Madariaga and I. D. Brown. I. D. Brown also stepped down as Chair after 15 years of dedicated service, for which I would like to thank him on behalf of the committee.
