Hi Martin,

Just looked at the JScience3 http://jscience.org/ site now, do you know 
if we will be upgrading this project to use some of the JScience3 stuff.

This is not planned in the near future, except the javax.units part (whic=
h should be made available=20
in a separated download).

JScience 3 has supports for CRS, but it is currently very very basic comp=
ared to the Geotools=20
referencing module. This part is not yet of any use to us (maybe it will =
change in the future, I=20
don't know). The rest of JScience may be of great use for scientists, but=
 I guess that JScience and=20
Geotools can be used together. I don't see any need right now for making =
Geotools dependent of JScience.

Hi Martin,

that is great the javax.units part is what i need. I am work on 
Susceptance and would like to define it in a way that is compatible with 
JScience, much the same way you did SEXAGESIMAL_DMS in geotools Units.

If we not using JScience3 then what Java Docs should I be using to find 
out what is there for my example.

But it is going to be replaced by JSR-275 (probably similar to JScience) =
if we can get to finish it...

I have put the latest JScience into lists.refractions.net, I am really 
very impressed with the Quantity side of things (aka the the part that 
is not Units). It appears to be a nice implementation of a "units" 
system like I have always imagined after reading "Analysis Patterns" ... 
Fowler.  That may or may not be a good thing as every later book he 
writes as a more and more simple example of the same idea: 
Quantity/Unit, Measure, Currency, Money.

Martin is there any chance we can take the good part of JScience3 and 
just skip out on their implementation of ordinates?

We will upgrate the javax.units package to an implementation which will probably be close to 
identical (from an API point of view) to JScience. But I would like that JSR-275 finish its work first.

For the other parts (quantities, etc.), it should at users choice. Once we switched the javax.units 
package, it will be compatible with JScience. I don't think that we need to use it in Geotools, but 
we should make sure to keep Geotools compatible with JScience.
