4.3.2.275.1 Content

This code system http://hl7.org/fhir/type-characteristics-code defines the following codes:

LvlCodeDisplayDefinitionCopy
1has-target Has TargetThe type is reference to external content else where that can have a type. This is associated with the use of ElementDefinition.type.targetProfilebtn btn
1has-range Has RangeThe type has a value domain that is a range, and can be associated with allowable min/max values on it's ElementDefinitionsbtn btn
2  is-continuous Is ContinuousThe type is a continuous distribution. These types have issues associated with precision and equality, and can have a specified number of max decimal places (via an extension)btn btn
1has-length Has LengthThe type has variable length and be constrained by it's length. In principle, any type can be constrained by the number of characters to represent it, but this is not meaningful for numbers or attachmentsbtn btn
1has-size Has SizeThe type can be constrained by the number of bytes it takes to represent the content. This is usually applied to content that is compressed or interpreted, and there's no fixed relationship between the number of bytes of content, and the number of characters it representsbtn btn
1can-bind Can BindThe type can be bound to a terminology. Note that a classic binding has system|version|code|display, but not all bindable types carry all four of these, and how they are bound varies, so an additional extension is required to enable tools to work with this contentbtn btn
1has-units Has UnitsThe content has units of measure (UCUM, by implication) and it may be useful to constrain the units by some valuesetbtn btn
1do-translations Do TranslationsThe content is uncontrolled human readable text that may make sense to translatebtn btn

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
