The Chado Natural Diversity Working Group has been established with the aim of getting the Chado Natural Diversity Module into the production version of Chado.

As of x, it has been ...

Linking phenotype with genotype is an important and challenging task in biological research. To meet this need, a database for efficiently storing, querying, and analyzing large studies of this kind is necessary.

A new Chado module called Natural Diversity has been developed to store any type of experiment that either uses or generates specimens or stock organisms. ... and genotypes.

Experiments may be grouped or structured hierarchically, whereas any kind of biological entity can be stored as the observed unit, from a specimen to be used in genotyping or phenotyping experiments, to a group of species collected in the field that will undergo further lab analysis.

I tried to adapt the abstract from here, but it doesn't really mention genotyping, which I thought was half the idea. Can you improve it? --DanBolser 21:54, 3 February 2012 (UTC)


See the discussion page for notes on what we've talked about and where we are heading. Once the discussion settle, a summary of decisions will appear here.


This section describes important events in the development of the module. Detailed discussion of functionality is a separate section below.


The initial version of the Natural Diversity Module was developed by several people associated with NESCent. The initial application was heliconius research. This first version was directly inspired by the Genomic Diversity and Phenotype Data Model (GDPDM), which comes out of Cornell. The GDPDM has great documentation and is also described in this presentation.



In the fall of 2009, Sook Jung of Washington State downloaded the initial version (becoming the first known user outside heliconius) and started looking at it with the goal of using for GDR, a plant genome database. Sook found that a number of things weren't clear, and her input led to a rethinking of the design, and to the formation of this working group.


Several working group participants met at a January 2010 GMOD Satellite Meeting during PAG 2010. Discussion has continued in teleconferences and on the Chado mailing list. The design has changed considerable during this time. It has become more Chadoesque: it is a very flexible and generic design.

As of July 2010, the schema is undergoing final tweaks before it is moved into production Chado.
