2012AA MEDLINEPLUS Source Information
VSAB: MEDLINEPLUS_20111228
Summary of Changes:
MRCONSO.RRF:
Removed atom "MedlinePlus Health Topics" (TTY = HT) . This
atom, which was created during Metathesaurus processing, was not
necessary since Local Topics are no longer released.
Changed TTY for "Groups" from PT to HT
Assigned SDUI to Groups (HTs)
Changed TTY for "Groups" from PT to HT
Assigned SDUI to Groups (HTs)
MRREL.RRF:
Relationships between MSH qualifiers and MEDLINEPLUS atoms were
incorrectly being labeled as RQ/mapped_from
New REL/RELA:
RT/mapping_qualifier_of between TQ and MEDLINEPLUS atom
Dropped REL/RELA:
RQ/mapped_from between TQ and MEDLINEPLUS atom
Corrected STYPE values:
STYPE1 and STYPE2 are now set to SDUI for hierarchical (PAR/CHD/SIB) and other relationships. Previously these were AUI <--> AUI or AUI <--> CODE.
Corrected relationship group assignments:
Many rels were being assigned RG=1, but it should have been null. This resulted in many rels being grouped together incorrectly. The RG value has been changed to null as appropriate.

- Only English language records (langcode="English") are processed for the Metathesaurus. Spanish language records (langcode="Spanish") are not included.
- Even when duplicated, both ETs and SYs are
included for
complete representation of the source.
