Background
  • * Indicates blank relationship attribute (rela); not all relationships are assigned an attribute.
  • Orange colored rel/rela pairs indicate that the current row is an inverse relationship of the row above it. All relationships in MRREL.RRF are bi-directional.
  • Metathesaurus relationships are traditionally read from right to left.
  • Every row in MRREL.RRF has a RUI (relationship unique identifier).
  • Samples below are taken from MRREL.RRF, although not every field is shown. Associated terms (str) from MRCONSO.RRF are also shown for clarity.
  • Relationship abbreviations appear in MRREL, i.e., SY.
Relationship Definitions
  • AQ: allowed qualifier
  • CHD: has child (narrower hierarchical term)
  • DEL: deleted concept
  • PAR: has parent (broader hierarchical term)
  • QB: can be qualifier by
  • RB: has a broader relationship
  • RL: has similar or like relationship
  • RN: has narrower relationship
  • RO: has relationship other than synonymous, narrower or broader
  • RQ: related and possibly synonymous
  • SIB: has sibling
  • SY: source-asserted synonymy
