| Examples: | | | |
| Source | Target | Type of Mapping | Example |
| | | |
| Med Ctr Specific - Drug Names Only | RxNorm | Instance Mapping | Normalization of the name "Avandia" |
| ICD9 (a specific year) | ICD9 (ignoring concept persistence) | Association Mapping | Tagging ICD9 data for exposure |
| Med Ctr Specific | Harvard Taxonomy (CDC Race) | Association Mapping | Tagging existing race data for exposure |
| Med Ctr Specific | Harvard Taxonomy (CDC Race) | Instance Mapping | Normalization of race data |
| Med Ctr Specific | Harvard Taxonomy | Association Mapping | Tagging lab data for exposure (does not allow query by value) |
| Med Ctr Specific | LOINC | Instance Mapping | Normalization of all lab data into LOINC (allows query by value) |
| | | |
| Instance Map: Converts the actual data so that query by value is possible (also provides patient counts as well) | | | |
| Association Map: Tags the location of data in i2b2 so that it can be located and used for the generation of patient counts | | | |
