All codes in this table are from the system http://hl7.org/fhir/linkage-type
| Code | Display | Definition | 
| source | Source of Truth | The resource represents the "source of truth" (from the perspective of this Linkage resource) for the underlying event/condition/etc. | 
| alternate | Alternate Record | The resource represents an alternative view of the underlying event/condition/etc. The resource may still be actively maintained, even though it is not considered to be the source of truth. | 
| historical | Historical/Obsolete Record | The resource represents an obsolete record of the underlying event/condition/etc. It is not expected to be actively maintained. |

Explanation of the columns that may appear on this page:
| Lvl | A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information | 
| Source | The source of the definition of the code (when the value set draws in codes defined elsewhere) | 
| Code | The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract') | 
| Display | The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application | 
| Definition | An explanation of the meaning of the concept | 
| Comments | Additional notes about how to use the code |
