Is the MESH ID expansion in the example correct?

[cmungall]

{
  "@context": {
    "drugbank" : "http://identifiers.org/drugbank/",
    "mesh"     : "http://identifiers.org/mesh/",
    "schema"   : "http://schema.org/",
    "object"   : "schema:object",
    "ChemicalName" : {
      "@type" : "schema:name",
      "@id"   : "schema:name"
    },
    "ChemicalID"     : {
      "@type" : "mesh:",
      "@id"   : "mesh:"
    },

the data looks like this:

(0.017ferrocene)amylose,MESH:C089250,,,MESH:D000688|MESH:D005296,D01.490.200/C089250|D02.691.550.200/C089250|D09.301.915.361/C089250|D09.698.365.855.361/C089250,D01.490.200|D02.691.550.200|D09.301.915.361|D09.698.365.855.361,(0.017 ferrocene)amylose,

Expansion from values in a CSV is not covered in the JSON-LD spec but I understand the intention to be to treat the value like it's a string in a JSON doc

in which case shouldn't the context say

   "MESH"     : "http://identifiers.org/mesh/",

Which will make col2 expand to

http://identifiers.org/mesh/MESH:C089250

MeSH themselves provide an expansion of http://id.nlm.nih.gov/mesh/, eg. https://id.nlm.nih.gov/mesh/C089250

[cmungall]

But either way, the prefix in the context file must be capitalized to match the prefix in the data file?

[balhoff]

Ah yes, sorry, that is true. Getting distracted.
