Request for Distribution

Dear Colleagues,

most probably, you have received the RfC below several times already.
However, there may be many more people interested apart from those reached
by the mailing lists given below. So please, do re-distribute the request
in your country to user communities that may not have it yet, and in your
institute to colleages who may not be reached otherwise.

Please remember to put

Biological Collection Data Standard - Request for Comment

in the subject line, so that people are able to identify duplicates.

Thank you very much

Request for Comment

Dear Colleague,

The Access to Biological Collections Data (ABCD) Task Group is developing
an XML Schema as a data interchange standard for unit-level data. A unit
may be a specimen, culture, living organism, or observation of an organism.

The standard, intended for use in distributed query systems for unit-level
databases, has reached a degree of development where the Group welcomes
comments and suggestions from the wider community. The current draft of the
schema, labelled CTB version 1.39, can be found at the Content Subgroup's
Web-site at along with further
information about the project and the group itself.

The profile is available as a .xsd file or as a very large HTML file with
diagrams to show the structure. I may also be viewed through a special
browser-based schema viewer.

The Schema is intended to provide a comprehensive basic structure and is
consequently quite large and highly structured. It will be used as the
standard format in which the results of a distributed query will be

The Group seeks comments on the adequacy of the element set and the
definition of the element's semantics ("documentation"). We would
particularly value comments on where the element count may be reduced,
rather than enlarged, without impairing its function.

Please would you take a look at the current draft, and send comments and
suggestions to abcd at by the December 3, 2002.

For the ABCD Standard Editors Group
J. Croft, N. Thomson, and W. Berendsohn
