4.1

client

software component that can invoke an operation from a server(4.16)

[SOURCE:ISO 19128:2005, 4.1]

4.2

coordinate

one of a sequence of n numbers designating the position of a point in n-dimensional space

[SOURCE:ISO 19111:2007, 4.5]

Note 1 to entry: In a coordinate reference system(4.4) , the coordinate numbers are qualified by units.

4.3

coordinate operation

change of coordinates(4.2) , based on a one-to-one relationship, from one coordinate reference system(4.4) to another

[SOURCE:ISO 19111:2007, 4.7]

Note 1 to entry: Supertype of coordinate transformation and coordinate conversion.

4.4

coordinate reference system

coordinate(4.2) system that is related to an object by a datum

[SOURCE:ISO 19111:2007, 4.8]

Note 1 to entry: For geodetic and vertical datums, the object will be the Earth.

4.5

gazetteer

directory of instances of a class or classes of features containing some information regarding position

[SOURCE:ISO 19112:2003, 4.2]

Note 1 to entry: The positional information need not be coordinates(4.2) , but could be descriptive.

4.6

geographic identifier

spatial reference(4.19) in the form of a label or code that identifies a location

[SOURCE:ISO 19112:2003, 4.3]

4.7

interface

named set of operations that characterize the behaviour of an entity

[SOURCE:ISO 19119:2005, 4.2]

4.8

place

identifiable part of any space

4.9

Place Identifier

pi

reference that identifies a place(4.8)

Note 1 to entry: The same place may be referenced by multiple Place Identifier(4.9) instances. Each instance will be associated with a different reference system.

4.10

Place Identifier application

PI application

application providing services(4.17) that use Place Identifiers(4.9) to end users(4.21) or other applications

4.11

Place Identifier matching

PI matching

matching of a Place Identifier(4.9) specifying a place(4.8) with another type of PI identifying the same place

Note 1 to entry: A source PI can be matched with multiple target Place Identifiers.

Note 2 to entry: PI matching(4.11) can be made among coordinates(4.2) , geographic identifiers(4.6) and identifiers in the virtual world such as URI.

4.12

Place Identifier platform

PI platform

group of service(4.17) interfaces(4.7) and data structures used for PI matching(4.11)

4.13

registration

assignment of a permanent, unique, and unambiguous identifier to an item

[SOURCE:ISO 19135:2005, 4.1.12]

4.14

request

invocation of an operation by a client(4.1)

[SOURCE:ISO 19128:2005, 4.10]

4.15

response

result of an operation returned from a server(4.16) to a client(4.1)

[SOURCE:ISO 19128:2005, 4.11]

4.16

server

particular instance of a service(4.17)

[SOURCE:ISO 19128:2005, 4.12]

4.17

service

distinct part of the functionality that is provided by an entity through interfaces(4.7)

[SOURCE:ISO 19119:2005, 4.1]

4.18

service metadata

metadata describing the operations and geographic information available at a server(4.16)

[SOURCE:ISO 19128:2005, 4.14]

4.19

spatial reference

description of position in the real world

[SOURCE:ISO 19111:2007, 4.43]

Note 1 to entry: This may take the form of a label, code or coordinate(4.2) tuple.

4.20

spatial reference system

system for identifying position in the real world

[SOURCE:ISO 19112:2003, 4.6]

4.21

user

active object that initiates service(4.17) requests(4.14) to the system

[SOURCE:ISO 19132:2007, 4.58]

Note 1 to entry: Users are usually objects that act as proxies for people accessing the functionality of the system.

Note 2 to entry: These objects can be a PI application(4.10) or creators of PI matching(4.11) tables and reference systems.
