[ome-devel] Metadata Questions

[Jason Swedlow]

Hello-

We are trying to get the use of metadata and the OME schema fleshed 
out.  But there seem to be some burning questions that need to be 
resolved first, at many levels.  In the not too distant future, we will 
want to fuse the OME Data Models with schemas/ontologies from other 
groups (MGED, GO, etc).  Having all these models is great, but it is 
very important to decide what must be filled out, and what to do when 
specific information is not provided.  MIAME is a great attempt at this 
in the microarray field.

In that spirit, we'd like to address some questions to the imaging 
field.  The following questions can be copied to other listserv's and 
synopses of answer(s) fed back here.

1) What is the minimal set of metadata we need to record about an image?

2) What actions do we take if an incoming file does not provide some of 
this metadata?  Do we use defaults, or do we force the user to give us 
the data?

3) Is/are there global minimal set(s), or do we leave to a local 
installation, providing them with the tools to define a local "minimal 
set" dependent on their needs.  How important will data sharing be?

4) Once this metadata is stored, what do we allow users to change?  If 
data was incorrectly entered, either into the acquisiton system or a 
data capture tool, is it OK for user to change?  Do we track these 
changes.

Thoughts?  For those of you who would prefer your responses to be 
private, emails sent directly to me will be kept confidential.  If 
permitted, their salient points will be summarized without 
identification.

Thanks in advance.

Jason
