Similarly, the value QS represents an unknown amount but may be converted to a real amount during the actual dispensing of a formulation. A private type is an internal “helper” abstraction, defined only for the purpose of defining some aspect of the semantics of data types but that is not used even as the type of another protected or public type’s property. Though it is pretty redundant in this case, the source system could indicate which translation comes from which using the source property:. QSET is for quantity based sets where it makes sense to build complex sets using expressions and ranges of values. For a quick overview at the beginning of many data types this specification contains tables listing “primary” properties. The nullFlavor property plays a special role in the conformance framework.

Note that this does not imply that applications are required to handle infinitely large collections of data, but the specification itself places no limit on the size of the collection. The time interval during which the given information was, is, or is expected to be valid.
Dell Dset dependent on version of Dell OpenManage –
Some of the values will have directly assigned numerical value suitable for some mathematical operations. Note that some familiarity with reverse polish notation is useful in this regard. The constraining model may apply a cardinality to an attribute. Thus, all binary data is — semantically — a sequence of non-null BL values.
The following rules apply to whitespace contained within values of type ST:. Therefore the formal definition of the data types in the Data Type Rset Language DTDL should be used for detailed specification of the data types. Also, typically, the simple type is declared earlier in this document than a more complex type.
Note that both head and tail being NULL does not mean that the sequence is empty; while this is a necessary condition of an empty sequence, it is not sufficient for determining an empty list, since a sequence may contain NULL-values as items. A unique identifier string is a character string which identifies an object in a globally unique and timeless manner.
A property of a data type is referred to by a name and can be evaluated for any value of a data type.
Data Types – Abstract Specification
Concept domains are bound to value sets in the context of dsey realm. The purpose of a code system name is to assist an unaided human interpreter of a code value to interpret codeSystem. Type conversions can be implicit or explicit. The return value may be null when the collection itself deet null, the number of items in the collection is not known.
The most important case is Act. ST data type interprets the encapsulated data as character data as opposed to bitsdepending on the charset property of the encapsulated data type. Find Blog Entries by MensaWater. Even more useful is to convey some dxet information about the concept, even though it cannot be represented in SNOMED:. In some cases, it may be unclear whether the code represents a single symbol or an expression.
The original text SHALL be an excerpt of the relevant information in the original sources, rather than a pointer or exact reproduction. Every data element has either a proper value or it is considered NULL. A private type is an internal “helper” abstraction, defined only 3.5.1 the purpose of defining some aspect of the semantics of data types but that is not used even as the type of another protected or public type’s property.
Complex business objects with many informational attributes can xset specified as abstract syntax, where components are eventually defined in terms of data types. Codes may be assigned a numerical value, but this is not required.
The number of elements in the set. Dswt alternative is to put none of the translations in the root, and give it a nullFlavor of choice, and put all the translations in the translation property of the root.
The HL7 vocabulary principles also provide for concept specialization for HL7 defined value sets.

List elements are enumerated, separated by semicolon, and enclosed in parentheses. For example, consider the following simple definition of a data type for cardinal numbers positive integers. A semantic rule is simply a semicolon-separated list of Boolean assertion expressions of the same kind as those used in invariant statements.
The displayName is included so that an unaided human interpreter of a code value has a human readable description of what the concept meant within the code system at the time of data entry.
A syntactic rule ends with a semicolon.
A code is required when it is present in the instance to meet some constraints imposed on the instance by the context of use.
