                     -------------  workshop -------------

                        led by Dr. Mike Dallwitz, CSIRO

                             12-15 September 1994

      The DELTA (DEscription Language for TAxonomy) format is the
internationally recognized standard for coding descriptive taxonomic
information.  The associated programs, which have been under development
since the mid 1970s, have facilities for maintaining data, producing natural
language descriptions and keys, interactive identification and information
retrieval, and converting data to formats required by programs for cladistic
and phenetic analysis.

      The DELTA system combines traditional taxonomic practice with modern
information science. A working knowledge of the system is a valuable skill
for all involved in the practice of teaching of biological information
storage,analysis and dissemination.

      This DELTA workshop is aimed at those already using DELTA to some
extent.  A prerequisite for the DELTA workshop will be that participants (or
at least one of each pair of participants at each computer) should have a
preliminary working data set at the start of the course (i.e. DELTA data
(CHARS, SPECS, ITEMS), TONAT, TOKEY, KEY, TOINT, INTKEY.INI).

      Numbers of participants are restricted to about 20-25, working singly
or in pairs on MS-DOS microcomputers.  The workshop will be led by Dr. Mike
Dallwitz (CSIRO Division of Entomology).

WORKSHOP PROGRAM

Mornings

Monday: Generating and typesetting natural-language descriptions. Adding
extra characters and reordering the characters.

Tuesday: Introduction to INTKEY - interactive identification and information
retrieval.

Wednesday: Generating printed keys; optimizing by weighting and parameter
adjustments.

Thursday: Advanced use of INTKEY - generating diagnostic descriptions and
group descriptions; extracting subsets of the data; generating files for
input to other programs; incorporating images in INTKEY data sets.
Translating DELTA data for input to phenetic and cladistic programs;
running the phenetic programs supplied with the DELTA package.

Afternoons

Development by participants of their own data sets. Exploration of existing
data sets (Grass Genera of the World; The Families of Flowering Plants;
Beetle Larvae of the World; etc.).

COSTS

      The fee for the workshop is $100 per person to cover the cost of
lunches, mid morning and mid afternoon snacks and incidentals related to the
workshop.  It is desirable for participants to bring their own computer, but
for those who are unable, a computer can be provided for a one week rental
fee of $135.

      Housing, breakfast and dinner are at the participant's own expense.  A
list of inexpensive housing in the Boston/Cambridge area will be provided.
A wide range of restaurants, from inexpensive to moderately expensive,
are within a 10 to 15 minute walk of the herbarium building.

NOTE:  workshop spaces are limited and enrolment is on a first come basis.
