Best way to create these tags about film

Hi!

I want to make the following custom tags about film:  FilmMake, FilmCategory, FilmProcess, FilmExpirationDate, Film BatchNumber, etc.  What's the best way, in some other people's opinion, how to do this?

Should I:

1.)  Make the EXIF tags?

2.)  Make XMP tags?

3)  Or, create a group of XMP, and then put the XMP tags in this group?

4.)  Or a better idea?

I finally got the .ExifConfig file to work in the home directory on my MAC, so I think I'm not too far away now...  :-)))  Thanks in advance for any ideas or suggestions.

Greetings, JP

Option 3 is the way to go.  If you create your own XMP
namespace, then there is no conflict with existing tags and
you will have maximum compatibility with other utilities
(provided they understand XMP).

I agree with Phil, option 3.

Ok, thanks for the thoughts on this.  I just have no idea how any of this will be compatible with other applications yet.  However, I anticipate a time, when applications like Lightroom, Media Expression, etc. will have customizeable EXIF, XMP sorting abilities...

Thanks and best, JP

In Bridge CS4 you can only filter by certain pre-defined tags at the moment (as far as I'm aware), however using the 'Find' facility (Ctrl/Cmd + F) you can search for a phrase in 'All metadata'.

So, for your example you could search for all photos with 'Velvia' in the metadata. You can also combine search items, so for example you can search for all photos taken with a certain camera model and 'Velvia' (or whatever) in the metadata.

As you say, I'm sure programs will improve their support for custom XMP fields, and far better to ensure your images are tagged up correctly now than to have to go back and re-tag them all when this support emerges.

OK, so I think I did everything right.  And it works! I think, I created a XMP subdirectory tag definition, added a name space and then the table of tags.

But, what do the following commands mean:
 

Code:

GROUPS => { 0 => 'XMP', 1 => 'XMP-FilmInfo', 2 => 'Image' }

Code:

NAMESPACE => { 'FilmInfo' => 'http://ns.myname.com/FilmInfo/1.0/' }

Code:

{ Groups => { 2 => 'Author' } }

Would appreciate any comments, cause I wonder, if what I did was REALLY right... After all, I didn't add any structure tags or anything...

In any case, I can add the info to the tags etc...

Cheers, JP

ps.-Dave, I will post my config file online soon.  Shall we discuss best practices for labeling film info?

The groups are used only by exiftool to allow you to
organize tags by group name.  The groups are not
written to the XMP.

The namespace is a URI (unique resource indicator)
which is written to the XMP to uniquely identify your
namespace.   If this is unique, then your tags will not
conflict with any other existing namespace, even if
the tag names are the same.  You can take a look at the
XMP output to see how it is used.

I don't actually shoot film I'm afraid. I've just set up my own custom XMP tags similar to you, but for things like Filters Used, Additional Optics Used (e.g. teleconvertors, extension tubes etc.) rather than Film.
