This is the domain in which my interest in this area began. For many
types of TV production scripts (the words read by the narrator in a
documentary for example) are not written until the very end of
production, and EDL's are not created until late in production. Story
boards, research notes, shooting scripts, camera logs, lab notes, rushes
logs, and production notes are all important sources of metadata that
are created upstream in the process (and usually lost subsequently).

find
some example metadata for the use case.
No problem - I will let you have the example metadata as soon as I get
it from my colleagues.

Subject: [MM] Changes in response to comments by Chris Catton
Dear all,
Chris Catton from the Image Bioinformatics Research Lab of University of
Oxford sent me some very useful comments on the image annotation draft
in a private mail, and gave me permission to forward them to this list:
>You talk too about Different vocabularies for different types of
>metadata. In our domain, we think it's important to go a step further
>and not just distinguish metadata about the properties of the image
>itself from those describing the subject matter of the image. We also
>think it is important to distinguish 'ground facts' (I killed a rabbit,
>took out its liver, sectioned it and observed it under a microscope')
>from interpretation - 'The drug I gave the rabbit appears to have cured
>its cirrhosis'. This is a difficult philosophical distinction, but one
>that is important to capture somehow. We also see this as a separate
>issue from the use of domain-specific vocabularies for annotation.

I fully agree, and I vaguely remember this distinction was made in
earlier versions of the draft. Anyhow, I've rephrased the title to make
it more generic (it now reads "Different types of metadata" iso
"Different vocabularies for different types of metadata") and added the
following sentence to that section:
In many applications, it is also useful to distinguish between
objective
observations ('the person in the white shirt moves his arm from left
to right')
versus subjective interpretations ('the person seems to perform a
martial arts exercise).
Note that I changed the example. I thought Chris's example was a bit
too
domain specific, but I 'm not too happy with this one either, So I'm
open for suggestions.

Yes, this is, in my opinion, the number one best practice in multimedia
annotation.
I still cannot believe how we missed this in draft :-(
I added the following item as the first in the issues list in the intro
section:
1.
Production versus post-production annotation
Typically, most of the information that is needed for making the
annotations is available during production time. Examples include
time and date, lens settings and other EXIF metadata added to JPEG
images by most digital cameras at the time a picture is taken,
experimental data in scientific and medical images, information
from scripts, story boards and edit decision lists in creative
industry, etc. Indeed, maybe the single most best practice in
image annotation is that in general, adding metadata during the
production process is much cheaper and yields higher quality
annotations than adding metadata in a later stage (such as by
automatic analysis of the digital artifact or by manual
post-production data).

I asked Chris to try to find some example material from his project so
we can put together a scientific use case from the bio imaging domain.
I also added his name to the acknowledgement sections.
Chris, thanks again for your comments and I hope you will manage to find
some example metadata for the use case.
Best regards,
Jacco
