Use cases for hierarchy:

[dosumis]

Grouping related content in indexes of sites/APIs. Table of what relations are safe for grouping and what are not.

• Connection relationships are interesting and useful, just not for grouping content.
• Inputs to validation - simple hierarchies with unlabelled edges can't do justice to the complexity of relationships https://docs.google.com/document/d/1xpzQUAJVzwGjWenLlLYrgYyinTaHRZJy_77sWdLR0AY/edit#bookmark=id.okxjqd213naz - in the example here not all relationship types are safe for grouping.
• [ ] #12

I am not sure where to label has part (safe or unsafe for grouping): https://docs.google.com/presentation/d/1xSt9xhrGS5SwsijGpyJdzuyJw1zOprqkA0nXMvNI588/edit#slide=id.g2a277e6e74e_0_25

Update: Unsafe, and added a new column for partly safe.

All of Uberon + CL

Count relationship usage for - Uberon:Uberon; Uberon:CL; CL;Uberon.

Because I'm merging uberon.owl and cl.owl, I added the three tables to the images - paper folder.
