		       ** FIRST ANNOUNCEMENT **


    The Third International Meeting on Microarray Data Standards,
		Annotations, Ontologies and Databases
                
       March 29-31, Stanford University, Palo Alto, California


	     For information and registration please see:

		    http://www.dnachip.org/mged3/


	 Working group meetings are scheduled for March 28th.


INTRODUCTION

The goals of this meeting are to present the results of the standards
developed so far and engage the microarray community in the continued
development of these standards.  The underlying goal is to facilitate
the establishment of gene expression data repositories, comparability
of gene expression data from different sources and interoperability of
different gene expression databases and data analysis software. Since
1999 the group has had two general meetings, held in European
Bioinformatics Institute in November 1999 (see Nature, 403, 17 Feb,
699-700) and EMBL/DKFZ in May 2000 where draft recommendations on
microarray data representation and annotation were accepted and five
working groups were established.

The focus of MGED <URL: http://www.mged.org> is to provide a
collaborative atmosphere where the basic and central issues of data
gathering, handling and analysis of high-throughput gene expression
technologies can be discussed and (hopefully) solved.  Primary
interests of MGED are reflected in its working groups, which include:

  1) Experiment description and data representation standards
  2) Microarray data XML exchange format
  3) Ontologies for sample description
  4) Normalization, quality control and cross-platform comparison
  5) Future user group: queries, query language, data mining

Participants in MGED working groups include individuals from a wide
variety of academic, governmental, non-profit and commercial entities.

Two documents have been prepared since MGED2:

   MIAME : http://www.mged.org/Annotations-wg/index.html
   MAML  : http://sourceforge.net/projects/mged/

MGED3 will include three tutorial sessions: use of MIAME/MAML
standards, Data normalization methods and experimental design.

FORMAT

The number of participants will be restricted to 350. The meeting will
begin by a plenary session that will include reports from the working
groups, review of recent developments in microarray repository
databases (including GeneX, GEO, ArrayExpress) and other related
developments.  See the agenda for a detailed program.

In anticipation that this meeting will be over-subscribed we have
placed two requirements on all registrants.

   1) Everyone must submit an abstract, deadline is March 1st.
   2) Registration will be limited to no more than three members of one
      laboratory or company.

A total of 50 participants will be chosen to present a poster.

WORKSHOP ON MICROARRAY DATA ANNOTATIONS:

March 28 -  9:30 am - 2:30 pm 

The Microarray Annotations working group was established at MGED 1
meeting in November 1999 (see www.mged.org). The group has developed
recommendations for Minimum Information about a Microarray Experiment
- MIAME, the aim of which is to ensure the interpretability of the
data, as well as potential verification of the experimental results by
third parties (see URL below). The goal of the workshop at MGED 3 will
be to adopt the final draft of MIAME recommendations and to discuss
the possible future work of the group.  For more information follow

WORKSHOP ON ONTOLOGIES:

March 28 -  3:30 pm - 6:30 pm

A common and consistent representation for describing microarray
experiments is essential for efficient exchange, interpretation, and
(ultimately) comparison of results. Ontologies are being sought and
developed to provide this representation of microarray experiments at
three levels: sample description (e.g., taxonomy); an experimental
study (e.g., relationship of components); relation to other knowledge
domains (e.g., sequence annotation, gene function). The workshop will
begin with a review of issues raised at prior meetings.  Efforts to
address the species-specific nature of sample descriptions will be
discussed. Proposals to provide an ontology of a microarray study will
be considered.
