3.2.6.2.2. Cross Maps Table - Summary
An indication of the types of rules used in the Cross Maps and Cross
Map Targets.
Each row in the Cross Maps Table represents one option for mapping a Concept to a Cross Map Target.
There may be several Cross Map options for a Concept. If so, each option is represented by a row in the
Cross Maps Table. Each row may include rules for choosing that option and these rules may be expressed
in machine-readable form and/or as textual advice to support manual coding.

3.2.6.2.3. Cross Map Targets Table - Summary
The unique SNOMED CT Identifier for the Cross Map Set of which this
Cross Map is a member.
The SNOMED CT Identifier of the mapped Concept.
An integer that distinguishes between alternative mappings for a single
Concept.
Indication of the suggested order in which to present a series of options
for mapping a Concept for manual assessment. The first of these is the
default option for mapping the Concept.
The unique SNOMED CT Identifier for a CrossMapTarget to which this
Concept can be mapped.
A machine processable expression of rules that determine whether this
is an appropriate Cross Map.
Textual advice to support manual mapping decisions between this Cross
Map and other options for mapping the same Concept.
Each row in this table represents a code or set of codes in the Target Scheme, which provides a mapping
for one or more SNOMED CT Concepts. A Cross Map Target may include a rule indicating the conditions in
which it applies; this feature is not used in any Cross Map currently released by the IHTSDO.
