One good example of this is the gatherer
it searches many of the big plant databases and combines the results
of all in one very big web page. Very simple to implement, and
has a good selection of info sources. Might lack a bit on user
interface side but it does its job.

Yes indeed, one of the big problems here is design of the user
community. What I guess will be needed is one or two people to hold the
thing together, maintain the primary code and data sources and
moderate the list discussions to keep them on target.
The way things seemed to have worked with many of the big
openSource projects (linux/perl/...) is one person had been mainly
responsible for version 0.1. When the core code is written
then its time for bug checkers and feature adders to join in and
take things to version 1.0. The fun really starts around version 3:
the first major rewrite, by that time the should be a committed
enough community to have a real good argument!
Maybe its worth going to sourceForge this seems to be the central
focus of much opensource development and much of the structures
needed to run the project are ready built in.
My mind recalls some stuff I picked up recently on a teacher
training course. There are four stages in a group dynamic
forming - just building relationships
storming - heated discussion about everything
norming - arriving at a common objectives
performing - getting on with it.
We probably still in the forming stage here, maybe its time
to come up with some solid structures so that we can have
something to storm about.
As a help to any on these lists, I'm happy to let people have the
pfaf dataset (and code if they are mad enough!). I'm sure we can
workout something in licence terms later.

One point: its a good idea to have a system which can work online
and offline. It is a pain to have to log onto the internet every
time you need to search for a plant. PHP/MySQL might do this job nicely.

I disagree a bit here. If you look at all the coding books they
are very heavy on design first, but if you actually go talk to the
coders it quite another story. Get something quick and dirty running
learn by your mistakes, improve, make more mistakes, redesign, go back
to the idea you first though of, etc. Getting some data in early will
be good to get some idea of what's needed.

True, contradicting what I just said earlier.
OK some thoughts on the data structure:
actually before looking at this its well worth having a look at all the
other databases out there, there are a supriseing number out there.
I've a fair few links to other sites see
Meta-data: (about the contributor)
Person (probably linked to a contributors table)
Date (submitted, accepted)
Notes (what still needs doing)
Notes (what was changed)
might want to note in text what was changed by who.
Plant Data - data can be entered at all levels:
Often there are common characteristics common to
all plants in a particular genera/family
and also particular cultivars will have differences
from the main species.
Author (allow for multiple names one field for each)
different fields for each bit of name will make somethings easier,
might be possible to automatically combine into another field.
I've had a few problems parsing the Author fields.
Each synonym should also have above data.
A feature should allow for the differences in gender endings
on the plant names and these can be rather inconsistent.
Location name in use
might want to get the good name dataset from
plenty of other places to pinch names from (ask me for details
General Text description about the plant. A fairly informal
description about the plant. Useful as the key attention grabber
about the plant, go to be short to the point attention grabbing.
Will appear at the top of page.
One of the most useful fruit bearing trees around.
It grows all over the northern hemisphere. The fruits are delicious
and very nutritious. There are hundred of cultivars of the plants.
Cultural Info about the plant:
Apples have a long history in british folk lore, the
practice of wassaling still carries on today. ....
Got to be as tight as possible, maybe counties in UK,
states in US (or smaller).
Should specify whether its native to each area or introduced. Could
have lots of fun with the user interface to this bit so you could
draw a map and click on it to add those areas.
Hazards to health
Invasive species, noxious weeds, controlled plants.
Plants particularly noted for pest carrying.
References to official documentation.
Life-span or life cycle
Time to first fruiting
Height and Width
max and min for full grown plants. Some indication as to
how long it takes to reach these.
The hardiness zones plant grows in. Maybe want to specify
a range of zones for these. Of more use to US people than rest
of world. Might want some more useful info such as conditions
in which the plant can survive (min temp),
and conditions necessary for it to bare fruit (length of growing
General growing conditions:
(for all of these will need to indicate if data not
Ph ranges (or very acid, acid, normal, base, very alkaline)
Soil types (in the text fields we have about 50 different
soil type listed. See
Noted Pest & Diseases:
Another tricky one lots of possible habitats:
Cultivation and propagation:
Quite a few sub categories. #include <gardenerinput.h>
yield (we completely missed this one!)
(we mixed up the part and the use in the same field)
for the categories we go and the ones we missed.
The ethnobotany database has a very good table of plant uses.
Vitamins, Carbohydrates etc.
Scientific name and common language description of conditions
we are week on treatment, which is being rectified by our
Quite a tricky one as the uses are so diverse and two different
names can be used for same use.
Should be easy to add a new use. Might want some way to
link the use to other related uses.
Phew, I think I've run out of breath!
Hope your solstices were cool
