VSAB: HL7V3.0_2016_07

Summary of Changes

There are no changes to the source format or to Metathesarus source processing.

Source Provided Files:

The HL7V3.0 source is provided in DEFN-20160728.coremif. Elements in this file can be described by their path of xml tags starting from the root. In the xml path descriptions below, an XPath-like format is used to describe the origin of various items, but the top-level <vocabularyModel> path element is omitted for brevity.

Note that some HL7V3.0 elements, such as <conceptProperty>, use a "name, value" format instead of nested xml tags to represent properties, e.g., <conceptProperty name="status" value="retired"/> instead of <conceptProperty><status>retired</status></conceptProperty>. Such a "name, value" item is represented in the xml path descriptions below using the format "conceptProperty/@name=status".

Identifiers:

HL7V3.0 SAUI and SDUI identifiers are not assigned. There are several types of HL7V3.0 atoms that each get different assignments of CODE and SCUI identifiers, as follows:

Concept Type Origin (xml tag path under <vocabularyModel>)
BR CODE = bindingRealm/@name
SCUI = bindingRealm/@name
CDO CODE = conceptDomain/@name
SCUI = conceptDomain/@name
CPR CODE = codeSystem/releasedVersion/supportedConceptProperty/@propertyName
SCUI = codeSystem/releasedVersion/supportedConceptProperty/@propertyName
CR CODE = codeSystem/releasedVersion/supportedConceptRelationship/@name
SCUI = codeSystem/releasedVersion/supportedConceptRelationship/@name
CSY CODE = codeSystem/@name
SCUI = codeSystem/@codeSystemId
PT, NPT, OP, ONP
CODE = codeSystem/releasedVersion/concept/code/@code
SCUI = codeSystem/releasedVersion/concept/conceptProperty/@name=internalId
VS CODE = valueSet/@id
SCUI = valueSet/@id

Atoms (MRCONSO):

  (return to top)
Term Type Origin (xml tag path under <vocabularyModel>)
BR CODE = bindingRealm/@name
STR = bindingRealm/description
SCUI = bindingRealm/@name

CDO
CODE = conceptDomain/@name
STR = conceptDomain/@name
SCUI = conceptDomain/@name
CPR CODE = codeSystem/releasedVersion/supportedConceptProperty/@propertyName
STR = codeSystem/releasedVersion/supportedConceptProperty/@propertyName
SCUI = codeSystem/releasedVersion/supportedConceptProperty/@propertyName

CR
CODE = codeSystem/releasedVersion/supportedConceptRelationship/@name
STR = codeSystem/releasedVersion/supportedConceptRelationship/@name
SCUI = codeSystem/releasedVersion/supportedConceptRelationship/@name
CSY CODE = codeSystem/@name
STR = codeSystem/@title
SCUI = codeSystem/@codeSystemId
PT, NPT,
OP, ONP
CODE = codeSystem/releasedVersion/concept/code/@code
STR = codeSystem/releasedVersion/concept/printName/@text
SCUI = codeSystem/releasedVersion/concept/conceptProperty/@name=internalId

Notes:
- Non-preferred term types (NPT or ONP) are used where codeSystem/releasedVersion/concept/printName/@preferredForLanguage="false"
- Obsolete term types (OP or ONP) are used where codeSystem/releasedVersion/concept/code/@status is "retired"
- Some retired concepts are defined with a code and an internalId but have no printName; these concepts are given STR = "Retired Code"
VS CODE = valueSet/@id
STR = valueSet/@name
SCUI = valueSet/@id

Definitions are created as follows:

Concept type Origin (xml tag path under <vocabularyModel>)
CDO conceptDomain/annotations/documentation/definition/text
CPR codeSystem/releasedVersion/supportedConceptProperty/description
CR codeSystem/releasedVersion/supportedConceptRelationship/description
CSY codeSystem/annotations/documentation/description/text

Hierarchical relationships are created in 3 situations:
(1) Between each PT concept and the CSY concept it is embedded in,
(2) Among PT concepts as specified by codeSystem/releasedVersion/concept/conceptRelationship elements where @relationshipName is "Specializes", and
(3) Among CDO concepts as specified by conceptDomain/specializesDomain elements.
RO classifies_class_code
class_code_classified_by
codeSystem/releasedVersion/concept/conceptRelationship where @relationshipName is "ClassifiesClassCode"
RO component_of
has_component
codeSystem/releasedVersion/concept/conceptRelationship where @relationshipName is "ComponentOf"
RO context_binding_of

Attribute Name Origin (xml tag path under <vocabularyModel>)
HL7BR contextBinding/@bindingRealmName
HL7CST contextBinding/@codingStrength
HL7ED contextBinding/@effectiveDate
