[ome-users] Schema for instrument/magnification - how to use?

[Graham Klyne]

I'm looking through the XML scema for "instrument" in OME [1].  I see there 
is an element for the objective lens, with a magnification factor value.

The researchers here also use, and wish to record, an "optivar"  with 
possible magnification values of 1, 1.25, 1.6, 2.  Am I overlooking a 
schema element for this?

I'm also a bit puzzled by the user interface for adding information about 
the instrument:  it seems the instrument annotation can be attached to a 
dataset in the UI (even though it is used in the top-level <OME> element in 
the XML schema description).  The drop-down list shown on the dataset 
display provides only two options, but if I select "create" anyway, a 
further drop-down list with many more options is provided.  Selecting 
instrument, I get a form for entering microscope type, srial number, etc., 
but there is no option there for entering objective data.  It feels to me 
as if there is a disconnect between the schema and the interface, but I'm 
not seeing any logic for this.

Having created some description of the instrument, and clicked "create 
instrument", there is no indication that any information has been attached 
to the dataset.  I fear I'm getting completely lost and confused by the 
user interface here.
