Some xrefs map to multiple mondo terms

[dst1]

I hope this is the right place and way to reference this issues.

I'm using the MONDO ontology json from obofoundry downloaded at 26.09.2019
I found 4 cases where a single xref maps to multiple MONDO terms (presented here in json like form):

{
  "HP:0001651": [
    "MONDO:0015661",
    "MONDO:0004823"
  ],
  "HP:0000010": [
    "MONDO:0001650",
    "MONDO:0005247"
  ],
  "MESH:D006524": [
    "MONDO:0025085",
    "MONDO:0006011"
  ],
  "HP:0001941": [
    "MONDO:0006022",
    "MONDO:0041261"
  ]
}

Specifically:

• MONDO:0015661 and MONDO:0004823 are both the same as HP:0001651 (semantically) however are found in different places at the ontology tree. Also, MONDO:0004823 should be labeled with Orphanet:1666.
• HP:0000010 - is neither MONDO:0001650 nor MONDO:0005247 as it is recurrent. I couldn't find a suitable alternative in HPO. Medically, MONDO:0001650 should be a descendant of MONDO:0005247 as it is an infection of a bladder. This will solve another placement issue of MONDO:0001777 found under both of these.
• MONDO:0006011 includes both viral hepatitis in humans and animals - MESH:D006524, MESH:D006525, MONDO:0025085 is exactly MESH:D006524 (animals). I'm not sure how and if this can be resolved.
• MONDO:0006022 is exactly HP:0001941 while MONDO:0041261 can also potentially include alkalosis and so shouldn't refer to HP:0001941.

also the MESH urls on the site are broken:
https://meshb.nlm.nih.gov/record/ui?name={ID}
instead of the working:
https://meshb.nlm.nih.gov/record/ui?ui={ID}

Thanks @dst1!

1. I think MONDO:0015661 'dextrocardia (disease)' and MONDO:0004823 dextrocardia should be merged. @cmungall or others, any objections?
2. I agree, I will make these edits on a branch and do PR:

• remove HP_0000010 'Recurrent urinary tract infections' as a dbxref from MONDO:0001650 'acute cystitis (disease)' and MONDO:0005247 'urinary tract infection (disease)'.
• move MONDO:0001650 'acute cystitis (disease)' to a child of MONDO:0005247 'urinary tract infection (disease)'.

3. MESH:D006524 is labeled as MONDO:NonHumanEquivalent. I feel like this addresses this issue, no?
4. I will remove HP: 0001941 as an dbxef to MONDO:0041261 'disorder of acid-base balance'
