EODEM
This page provides an introduction to EODEM, the Exhibition Object Data Exchange Model, and links to related resources. The development of EODEM is being coordinated by the CIDOC Documentation Standards Working Group (DSWG).
Public beta launched
The public beta version of EODEM was launched at a workshop for software vendors and suppliers on 22 May 2022, during the CIDOC annual conference in Tallinn. Specifications are available here; links to further support and advice can be found at the bottom of our FAQ page.
We encourage software suppliers to trial developing EODEM exporters and importers, and to feed their experiences back to the EODEM project group – either by joining our Google Group, or directly. This feedback will shape the final release of the model. In both cases, please contact Rupert Shepherd via http://rupertshepherd.info/contact.

What is EODEM?
A framework that will enable museum databases to export objects’ data from one system at the press of a button, and import the data into another system at the press of a button.
Why is EODEM necessary?
Because, in a normal year, museum staff manually copy the details of thousands of objects from their databases, and send them to other museums that wish to borrow those objects. The borrowing museums’ staff then manually copy those details back into their own systems.
To take just one example, over the ten years from 2010 to 2019, staff at the National Gallery in London entered the details of between 180 and 607 new exhibition loan objects per year into their collections management system – an average of 405 a year.
Assuming six hours per working day are spent doing actual work (rather than going to meetings, drinking coffee, chatting, etc.), that means that their quietest year saw between 7 and 10 days spent on data entry, and their busiest, between 25 and 33. So on average, they’ve spent between 16 and 22 days a year entering exhibition object data into our collections management system – a total over the ten years of somewhere between 164 and 224 days: as a worst case, that’s an entire working year over the last ten years spent on data entry. And those figures ignore the work done providing information for loans out.
To be fair, the National Gallery does have a comparatively large exhibition programme – but it’s still fairly typical of large museums. In order to better understand the pressures on museums caused by loans in and out, the DSWG conducted a survey to find out how much time staff currently spend copying-and-pasting, or retyping, information into different systems whenever they lend or borrow objects. This revealed that, assuming staff spend a full seven hours a day on data-entry, over a ten year period, the median time spent entering data for loans in was 48 days, and the mean 127 days – very nearly 7 months, so well over half a working year. And in the case of one institution, loan-in data entry would take 750 days: nearly 3½ working years. There are too many variables to convert these figures into salary costs, but there would seem to be a significant potential to make long-term savings if we can automate loan-related data entry.
