h1. Bone inventory concept

Initial meeting: 2024-12-09
Participants: Alex, Bernhard, Nina

Current (Januar 2025) approach is to:
* Add a new OpenAtlas class *bone* (CIDOC class E20 - human remains)
* Hard coded *Bone inventory* [[bone_inventory|hierarchy]]
* Add a system type *Bone preservation* with options:
** undefined (default)
** 0%
** 1-24%%
** 25-74%
** 75-99%
** 100%
** Number: used as "value type" to track counts of *Bone fragments* like, e.g. Rib 3-10 L/R
*** empty: no information available
*** 0: no fragments are present
*** 1+: positive integer as count of existing fragments

h3. To do

* Build prototype
* Test with example data from FemCare Vienna

h3. Structure

Besides connecting entities to category types, they will also connect between with P46 (composed of) to form a hierarchy
* These structure applies only to "editable" categories, others are used for display only

h3. Create new entries

* Data can be entered in a "guided" way starting with a button at the tool view of stratigraphic units
* We split the [[bone_inventory|categories]] into groups for easier data entry
* Default of *Bone preservation* will be *undefined* but entities for them will still be created for e.g. adding a description

h3. Adding information

* Bone inventory values can be added/adjusted similar to entering
* Once created it will be possible to add information in the detail view:
** A description can be added (like with all other entities)
** Images
** Additional types (which can be added via the type hierarchy interface), e.g. diseases, dimensions, ...

h3. Analysis

Sadly an analysis or a sum up function won't be possible due to inconsistency in used model, e.g.
* The sum of the parts of a category not always cover the entire category
* Mixing of arbitrary percent values (e.g. "25-74%") with arbitrary numbers where it is not known which value would present 100%
