Versione 2.0 del 6 novembre 2015 Defines the basic properties of every data value. This is an abstract type, meaning that no value can be just a data value without belonging to any concrete type. Every concrete type is a specialization of this general abstract DataValue type. Coded data in its simplest form, consists of a code. The code system and code system version is fixed by the context in which the CS value occurs. CS is used for coded attributes that have a single HL7-defined value set. A unique identifier string is a character string which identifies an object in a globally unique and timeless manner. The allowable formats and values and procedures of this data type are strictly controlled by HL7. At this time, user-assigned identifiers may be certain character representations of ISO Object Identifiers (OID) and DCE Universally Unique Identifiers (UUID). HL7 also reserves the right to assign other forms of UIDs, such as mnemonic identifiers for code systems. A globally unique string representing an ISO Object Identifier (OID) in a form that consists only of non-negative numbers with no leading zeros and dots (e.g., "2.16.840.1.113883.3.1"). According to ISO, OIDs are paths in a tree structure, with the left-most number representing the root and the right-most number representing a leaf. A DCE Universal Unique Identifier is a globally unique string consisting of 5 groups of upper- or lower-case hexadecimal digits having 8, 4, 4, 4, and 12 places respectively. UUIDs are assigned using Ethernet MAC addresses, the point in time of creation and some random components. This mix is believed to generate sufficiently unique identifiers without any organizational policy for identifier assignment (in fact this piggy-backs on the organization of MAC address assignment.) HL7 reserved identifiers are strings consisting only of (US-ASCII) letters, digits and hyphens, where the first character must be a letter. HL7 may assign these reserved identifiers as mnemonic identifiers for major concepts of interest to HL7. The character string data type stands for text data, primarily intended for machine processing (e.g., sorting, querying, indexing, etc.) Used for names, symbols, and formal expressions. A concept descriptor represents any kind of concept usually by giving a code defined in a code system. A concept descriptor can contain the original text or phrase that served as the basis of the coding and one or more translations into different coding systems. A concept descriptor can also contain qualifiers to describe, e.g., the concept of a "left foot" as a postcoordinated term built from the primary code "FOOT" and the qualifier "LEFT". In exceptional cases, the concept descriptor need not contain a code but only the original text describing that concept. A set of other concept descriptors that translate this concept descriptor into other code systems. The plain code symbol defined by the code system. For example, "784.0" is the code symbol of the ICD-9 code "784.0" for headache. Specifies the code system that defines the code. A common name of the coding system. If applicable, a version descriptor defined specifically for the given code system. A name or title for the code, under which the sending system shows the code value to its users. value set per significato DATE RVE value set per significato DATE RVE Codice prodotto farmaceutico (AIC) o codice prestazione specialistica Descrizione testuale del prodotto farmaceutico o della prestazione specialistica Codice del gruppo equivalente Descrizione testuale del gruppo equivalente Campo che indica di tenere conto solamente della descrizione inserita in descrTestoLibero Non sostituibilità del farmaco Motivazione della non sostituibilità Codici di motivazione di non sostituibilità di un farmaco Nota AIFA Quantita' di confezioni o di prestazioni specialistiche prescritte riservato SAC Campo riservato al codice del catalogo regionale della prestazione prescritta.
