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 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

To do¶

• Build prototype
• Test with example data from FemCare Vienna

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

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 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

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, ...

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%
