ASN.1 type

data type (or type for short) that represents in a formalised way a class of information (for example, numerical, textual, still image or video information); the representation is conformant to definitions given in ISO/IEC 8824-1

aspiration

expression of what a stakeholder wants the ITS implementation to provide, usually written in the language of the stakeholder and thus possibly having little or no formal structure
NOTE: There could be many aspirations for each ITS implementation, depending on its scope and the number of stakeholders that are involved.

associated ASN.1 type

type which is used only for defining the value and subtype notation for a type
NOTE: Associated types are defined when it is necessary to make it clear that there may be a significant difference between how the type is defined in ASN.1 and how it is encoded. Associated types do not appear in user specifications.

association end

endpoint of an association, which connects the association to a classifier

attribute

property of an element
NOTE 1 to entry: It is additional information about a piece of data (element). Often attributes are used to pass information about the element and hence can be said to provide metadata for the element. An attribute is a value indicator (=) and the attribute value is specified within the tag (i.e. ). Attribute in XML is a name="value" pair that can be placed in the…

NOTE 1 to entry: It is additional information about a piece of data (element). Often attributes are used to pass information about the element and hence can be said to provide metadata for the element. An attribute is a value indicator (=) and the attribute value is specified within the tag (i.e. ). Attribute in XML is a name="value" pair that can be placed in the start tag of an element. For XML, all values have to be quoted with single or double quotes.

composition

association where the target class is a composite; therefore the source class is a part that is strongly owned by the composite and may not be part of any other composite
NOTE: This characteristic is expressed in UML with an attribute named “aggregation” on the target side Association End being set to “composite”.

constraint

notation which can be used in association with a type, to define a subtype of that type

NOTE 1 to entry: Content may be made up of mark-up characters and character data.

data concept

data element, class, value domain, data frame, message or interface dialogue defined, at a minimum, with an unambiguous identifier and a definition
NOTE 1 to entry: In order to exchange a value corresponding to a data concept, more information than an identifier, a name and a definition can be needed. For a property, a data type is needed. Depending on the kind of property, other data…

data element, class, value domain, data frame, message or interface dialogue defined, at a minimum, with an unambiguous identifier and a definition
NOTE 1 to entry: In order to exchange a value corresponding to a data concept, more information than an identifier, a name and a definition can be needed. For a property, a data type is needed. Depending on the kind of property, other data elements such as unit of measure, and language, can be needed as well. The additional information can be given in the data dictionary, in a data specification that references the data concept or associated with the data themselves.

data concept registry (DCR)

electronic data dictionary that follows precise documented rules for the registration and management of stored data concepts

NOTE 1 to entry: The data concept registry contains meta-attributes about data concepts in terms of their names and representational forms as well as the semantics associated with the data concepts. A data concept registry may contain metadata that assists information interchange and re-use, both from the perspective of human users and for machine-interpretation of data concepts.
NOTE 2 to entry: A data concept registry typically includes advanced features for adding retrieving, and working with its contents.

data element

unit of data that is considered in a given context to be indivisible and which includes an unambiguous representational form
NOTE 1 to entry: This definition states that a data element is “indivisible” in a given context. This means it is possible for a data element considered indivisible in one context [e.g. location] to be divisible in another context (e.g. latitude, longitude, and…
