Advice appreciated for new custom tag layout

[geobernadotte]

Hello there,

I'm experimenting with exiftool now for only some weeks, but already love it (as far as i understand what i'm doing)
I think i'm not the only one being rather confused by the absurd amount of possible and impossible tags and their variations.

So, my target:
I receive plot images from biologists, taken during monitoring runs through the project area.
For the database, map creation and finally picture documention appendix of the report, i need some additional data which i now think to store best within the picture itself, too (after realizing that the gis-database with the data ate itself up partially), so i have kind of "backup" of those data.

What i would like to create are the following tags:
- Label: The number of the picture, needed for the map labeling of the location etc. (2 to 8 letters)
- Group: The group of species (2 letters: BI = Birds, DR = Drangonflies etc)
- Image Description german: Explanation what the picture shows (approx. 50 letters max)
- Image Description english: - "" -

Question: whats the best strategy to reach my goal?
- reuse/misuse already existing tags ?
 if so, which?
- create custom tags with a config file (shiver ...)
  if so, in which "part" of those (exif, xmp, iptc ... buzzz buzzz)

I'm completely confused by all those namespaces, main tables, groups, directories so far.


General or more specific advice really appreciated!

Hi Bernd,

I think i'm not the only one being rather confused by the absurd amount of possible and impossible tags and their variations.

Very true!

- Label: The number of the picture, needed for the map labeling of the location etc. (2 to 8 letters)
- Group: The group of species (2 letters: BI = Birds, DR = Drangonflies etc)
- Image Description german: Explanation what the picture shows (approx. 50 letters max)
- Image Description english: - "" -

I would suggest using XMP as long as any other software you may be using supports this:

1) XMP-xmp:Label
2) Your choice:  Either re-purpose one of the XMP tags (I suggest something from the dc or xmp schemas), or create your own
3) XMP-dc:description-de
4) XMP-dc:description

xmp:Label is already used in Bridge with a closed vocabulary: Select, Second, Approved, Review, To Do.

Perhaps dc:identifier or dc:title would be appropriate for Label.
