Summary of Changes

Slight changes have been made to the column order and location of fields in the .xlsx file.  While this required minor changes to Metathesaurus source processing, the essential model is the same.

Minor changes have been made to the representation of ICNP to SNOMEDCT mappings:  based on information asserted by the source, the majority of mappings are represented with REL = "SY" rather than "RQ".

Source Provided Files:

The file ICNP2013_072313.xlsx includes the following tabs:
   
DC Asserted   
IC Asserted
DC Inferred
IC Inferred
ICNP-SCT Mapping

Identifiers:

Identifiers are assigned as follows:
  • CODE: concept code
  • SAUI:  N/A
  • SCUI:  concept code
  • SDUI:   N/A

Atoms (MRCONSO):

  (return to top)
Term Type Origin
MTH_PT
American English form of British PT.  This data is added during Metathesaurus construction.
PT
Extracted from the "Preferred Term" value on the asserted tabs of the .xlsx file.
XM
Cross mapping atom to represent ICNP-SNOMEDCT map set.  This data is added during Metathesaurus construction.

Attributes (MRSAT):

  (return to top)
Attribute Name Origin
ICNP_TYPE
Inferred from the .xlsx file, based on which tab the concept appears on
FROMRSAB
This data is added during Metathesaurus construction.
FROMVSAB

Definitions (MRDEF):

  (return to top)

No definitions are present for ICNP.


Relationships (MRREL):

  (return to top)
REL RELA
Inverse RELA
ORIGIN
RB
RN
mapped_to
mapped_from
Represent non-synonymous relationships asserted by ICNP.  The REL value is based on the "Notes" field in the mapping data.
PAR
CHD
SIB
<no RELA>
Represent the hierarchy.  Extracted from "Parent Code" and "Child Code" data on the "inferred" tabs of the .xlsx file 
SY
mapped_to
mapped_from
Represent one-to-one relationships with SNOMED CT.  Mappings where the "Notes" cell is empty are represented as "SY".
SY
mth_british_form_of
mth_has_british_form
Connect MTH_PT to PT.
This data is added during Metathesaurus construction

Mappings (MRMAP, MRSMAP):

  (return to top)

SNOMED CT mappings are extracted from the ICNP-SCT Mapping tab on the .xlsx file.   Mappings are also represented in MRREL.RRF, with RELA = "mapped_to"

The following REL values are assigned based on the value in the "Notes" field:
    SY:  <null> (empty cell)
    RB/RN:  Inexact match (broader) or Inexact match (narrower)
    XR (MRMAP.RRF, MRSMAP.RRF):  No match
