Metadata EXIF and IPTC Model(s) for museo

As early hygiene, a Metadata system has been put in place while launching the War Heritage Institute Digitization Processes benchmark. This comes from a mail discussion that occurred around April 9th 2021. I republish it here for easier feedback. We can improve it along but these are basically the guidelines I had in mind while drafting this template :


This is based on the Kimball Metadata Archetypes from 2002.

Considering the actual Evolution of Data strategies best-practices, and incoming convergence between usual Corporate Document Management and Media Banking. I think we should keep in mind the Kaplan concepts, as a probable evolution of what a patrimonial institute data mindset should be :

Here is my actual draft on what I suppose would be a hygienic ecosystem, based on the usual questions quintet :
  1. - What
  2. - Who
  3. - Where
  4. - How
  5. - When
Document Management <a href=

My proposed actual Metadata Template involves a combination of 
  • EXIF Generic system (generic camera data, keywords, and description details)
  • IPTC International Press System (rights management, press release conditions, detailed location, and topic)
  • Custom Fields for internal asset lifecycle tracking (Item reference, description writing agent follow-up, document versioning)
I assume custom fields can be hidden to public view if you think some of these data may require a clearance level. At this point, my opinion about the collection reference number is not critical enough to be hidden to the public eye and does not justify the effort of exporting an alternative asset version just to remove it. But this is yours to arbitrate.
update: since the production of this, another workshop report explores the problematics around GPS coordinates location storage in metadata and its potential security issues.
For the rights managements, I propose to use the two types of rights usual policy :
  • Inalienable copyright: according to Belgian law, the original author of a creative asset keeps ownership until 70 years after the author's death.
  • Intellectual property rights: according to our signed convention, War Heritage Institute is the main owner of intellectual and distribution property rights
Considering this is a Non-Profit project, as we do usually for this kind of stuff, a Creatives Commons licence of CC-BY-NC-SA 4.0 Type  may offer a fair policy framework :
Again, this is to be discussed and, in fine, arbitrated with Museum's administrators.
Using Adobe Lightroom Classic software while importing and post-producing pictures, and the plugin Jb Listview for tracking table exports, we built the following template to be easily batch-applied on huge photographic databases :
