Hi Daniel,

Thank you for the updates! Before trying to answer you question about 
the link between OBI and Radlex, some content-related questions:

Reading Radlex description, I wondered how the link between a special 
relationhip like "part" and "parent"/"children" is dealt with. Something 
- a SPARQL query (when I ask for children, give me the parts)
- RDFS subtyping (part rdfs:subPropertyOf child)
- or dynamic interface generation (the "parent information not being 
encoded as such in the model, but derived when asking a visualization of 
the concept)?

Also I wonder whether a special relationhip can always be converted in 
parent/child link. There are some links, like "Continuous with" that do 
not seem to be interpretable naturally as hierarchical ones. But I am 
not sure, and could not find any example in my 5 minutes browsing...

Finally, what is the kind of mapping you envision/are developping? 
"Just" equivalence or subclass? Or more complex links?



PS: about the OBI description, wasn't there a small typo problem? What I 
have in the "Standards and guidelines considered" include:
"We is the use ofan an alphanumeric identifier for the term versus using 
the human readable term name. The reason for this was to remove 
semantics from the unique identifier for the term.render the identifier 
unique and ease term obsoletion and versioning."
