Processing services are services that perform large-scale computations involving substantial amounts of
data. Examples include services for providing the time of day, spelling checkers, and services that perform coordinate transformations e.g., that accept a set of coordinates expressed using one reference system and
converting them to a set of coordinates in a different reference system. A processing service does not include capabilities for providing persistent storage of data or transfer of data over networks.
Communication services are services for encoding and transfer of data across communications networks. System management services are services for the management of system components, applications, and
networks. These services also include management of user accounts and user access privileges. Not every information technology service needs to be changed or specialized to be useful for processing
geographic information. A separation between geographic services and IT services is made in ISO 19101. This separation is being focused on, because it is essential to identify and make use of general IT services whenever
they exist.
8.3 Geographic services taxonomy 8.3.1 Geographic services taxonomy requirements
The following sub-clauses shall define the geographic services taxonomy. The taxonomy shall consist of the titles of the categories Table 9 and the definitions for the categories. Definitions of the categories are provided in 8.2.
Systems compliant to this International Standard shall use the geographic services taxonomy to organize its services. A specific service shall be categorized in one and only one category, unless it is an aggregate service that
may perform services from more than one category.
The following sub-clauses provide examples of geographic services within the geographic services taxonomy. It is not required that a system provide any service listed in these sub-clauses. It is required that if a system provides a
service named in these sub-clauses that the service shall be categorized as defined in these sub-clauses. A service catalogue compliant with this International Standard shall categorize service metadata instances in the
categories of the geographic service taxonomy.
If a service uses the name of an example service, the service shall provide the functionality that is defined in these sub-clauses. For example, if a service titled catalogue viewer is provided, it shall perform the services defined for
the catalogue viewer in the geographic human interaction services category. Systems providing services should name services as found in the service examples.
