AS ISO 19103:2018 pdf free.Australian Standard  Geographic information – Conceptual schema language.
The use of realization is shown in Figure 4 where the interface GM_Point in package ISO 19107 is realized by a concrete class of the same name in a different package at the Application Schema level. Both classes reference the same information content, but it is the concrete one that may be implementable. This concept also applies to other abstract types defined in this International Standard.
6.9 Services
Behavioural aspects have no further requirements other than as in standard UML. Service architecture including approaches for identifying services is further described in ISO 19119.
6.10 Stereotypes and keywords
6.10.1 Introduction
Some additional basic stereotypes along with predefined stereotypes and special keywords of UML used in this International Standard are defined in 6.10.
Requirement 15. Conceptual models in the domain of geographic information shall use these stereotypes and keywords when appropriate, and shall not create alternatives with the exact same meaning.
6.10.2 Stereotypes and keywords
Stereotypes make it possible to extend the UML and give classifiers different meaning. This International Standard specifies the following stereotypes and keywords for the UML profile for geographic in formation:
a) <<CodeList>> is a flexible enumeration that uses string values forexpressing a list of potential values.
b) <<dataType>> is a set of properties that lack identity (independent existence and the possibility of side effects). A data type is a classifier with no operations, whose primary purpose is to hold information.
c) <<enumeration>> is a fixed list of valid identifiers of named literal values. Attributes of an enumerated type may only take values from this list.
d) <<interface>> is an abstract classifier with operations, attributes and associations, which can only inherit from or be inherited by other interfaces. Other classifiers may realize an interface by implementing its operations and supporting its attributes and associations (at least through derivation). See Annex B and mapping from UML ito UML 2.
e) <<Leaf>> is a package that contains definitions, without any sub packages.
f) <<Union>> is a type consisting of one and only one of several alternative datatypes (listed as member attributes). This is similar to a discriminated union in many programming languages. In some languages using pointers, this requires a “void” pointer that can be cast to the appropriate type as determined by a discriminator attribute.
Stereotypes are essential in the creation of code generators for UML models. Generally speaking, stereotypes act as flags to language compilers to determine how to create implementation models from the abstract models. Other stereotypes can be added in addition to the ones listed.
NOTE The names of stereotypes and keywords are not case-sensitive.AS ISO 19103 pdf download.
