very often it is useful to add meta data to publish files, e.g. colour space and frame range for images sequences, animation range for animation caches, etc ...
What would be the best way to do that with Tank ?
One solution would be to use a Shotgun custom entity to store meta data as fields, but fields might change a lot from one asset type to the other.
Another solution would be to store meta data as json code in a custom "blob" field on Tank published files.
A last one would be to store the json code in a file, and reference it from a field on Tank published files.
Wonder what would be the best solution to get it done ?
