Capitalisation rules for disease names

[azankl]

I noticed that some diseases in MONDO have their first letter capitalised, while others don't:

MONDO:0007037 achondroplasia
MONDO:0007041 apert syndrome
MONDO:0007043 Pfeiffer syndrome

I would prefer first letter capitalised, i.e. Achondroplasia.
In general, does MONDO have any rules on how to name diseases? I note that Orphanet has a whole protocol on how to name diseases and they recommend capitalising the first letter, as in Achondroplasia:

Does MONDO have something similar?

This is standard naming convention for ontologies and is an OBO principle: https://obofoundry.org/principles/fp-012-naming-conventions.html

It's a principle for a very good reason.

If I have an application where I want to place an ontology term in a sentence, then this is wrong with leading upper case:

the genes implicated in Lung cancer are ...

Also title case as used by NCIT is also wrong

the genes implicated in Lung Cancer are ...

And all-caps is also poor style

the genes implicated in LUNG CANCER are ...

It's hard to reliably downcase due to the presence of proper names in diseases; this is wrong:

the genes implicated in parkinson disease are ...

In contrast, if an application really wants to see leading upper case or title case, or even all-caps, this is a deterministic transformation without any ad-hoc rules

It's a good question, I'll leave it open for now until we add to our FAQ, then we'll close it, unless there are any further clarifications sought...

Thought you would have a good reason, that's why I asked ;-)
Agree with the concept of using lower case unless it's a proper name, but would argue that most rare diseases have a proper name. So all of the following should be capitalised as below (they are currently all lower case):

MONDO_ID	Name
MONDO:0007037	Achondroplasia
MONDO:0007041	Apert syndrome
MONDO:0007044	Acrodysostosis 1 with or without hormone resistance
MONDO:0007055	Acromicric dysplasia
MONDO:0007057	Acroosteolysis dominant type
MONDO:0007058	Acropectorovertebral dysplasia
MONDO:0007073	Hypoglossia-hypodactyly syndrome
MONDO:0007078	Pseudohypoparathyroidism type 1A
MONDO:0007114	Angel-shaped phalango-epiphyseal dysplasia
MONDO:0007124	Ankyloblepharon-ectodermal defects-cleft lip/palate syndrome

Would you agree? If yes, I will go through the list of skeletal dysplasias and submit tickets where the capitalisation is wrong.

Yes, we agree with your expert opinion, thanks @azankl. I updated the labels for the term above. Thanks for reviewing the other skeletal dysplasias, please report new tickets. Thank you!
