Announcing a new discussion list for developers of CIF software.
The Crystallographic Information File (CIF) sponsored by the IUCr is a
standard for information interchange in crystallography. First published
in 1991 to describe single-crystal experiments and data for
structures, CIF now covers macromolecular structure determinations and
powder diffraction studies, and extensions are under development for
image data, modulated aperiodic structures and other techniques and
disciplines within crystallography.
Although each CIF application uses the same basic file syntax, content
determined by external files (known as data dictionaries) that specify
relevant data model and carry information about data typing, validity
interrelationships. While customised applications can be written to
specific sets of subsets of CIF data, the most powerful applications are
dictionary-driven, so that they can use or be easily modified to use new
of data items as they are released.
Authors of software capable of handling CIFs are invited to subscribe to
discussion list for the sharing of experiences, information and code.
is open to anyone with an interest in developing software that is
with the published standards for reading and writing CIF data, and is
relevant to developers of software for the more general STAR File
that defines the syntax of CIFs. Authors of publicly distributable
especially welcome, but authors working in a commercial environment will
benefit from membership. The one strict condition imposed by the IUCr on
CIF-compliant software is that it should indeed comply with the
is hoped that the existence of a list such as this will halp developers
work within the standard, and to develop robust cross-platform libraries
tools for general use in the community.
Mailings to the list should be sent to the address
cif-developers at iucr.org
To subscribe, send an email message to the address
listproc at iucr.org
that contains a line of the form
subscribe cif-developers at iucr.org <your-name>
Further details may be found on the web page
Initially the list will be unmoderated (though the list manager reserves
right to moderate responses if there is an unacceptable level of junk
an archive of discussions will be accessible via the web at the URL
A supporting web page for developers will be maintained by the IUCr
team at http://www.iucr.org/iucr-top/cif/developers.html, which will
a Frequently-Asked Questions (FAQ) page.
Please forward this invitation to colleagues who may also be interested
