labels: -

value: <string>
<attribute>: <value>
inflectionals: [<string>, ...]
components: [<label>, ...]

concepts: -

<attribute>: <value>
pref_labels: [<label>, ...]
alt_labels: [<label>, ...]
broader: <concept>
narrower: <concept>
related: [<concept>, ...]

NB:

  • <label> and <concept> can either be strings referencing a previously declared entity or objects representing a new entity XXX: The latter is not currently supported yet!

  • order of concepts matters when referencing relations

  • order of labels matters when referencing components
