Extension Mechanisms

MRS provides explicit extension mechanisms to support additional domains while keeping a stable core. See: /MRS-Specification-RFC#13-extension-mechanisms

Custom Properties

Events, spans, and directions support custom properties with the x- prefix:

(: 0 C4.q 
  :id #uuid "..."
  :at 0
  :dyn f
  :x-source "manuscript-page-47"
  :x-confidence 0.85
  :x-variant "A")

Custom properties:

For complex extensions, use namespaced properties:

(: 0 C4.q
  :id #uuid "..." :at 0
  :analysis:roman-numeral "I"
  :analysis:function "tonic"
  :mei:xml-id "note-001")
