Requirement
Title | Need for information definitions |
Identifier | SWIM-INFO-001 |
Requirement | Exchanged information shall be documented in an information definition. |
Rationale | The requirement for information definitions is essential in order to facilitate semantic interoperability. Without information definitions, there are no resources to allow the meaning of the information to be clearly defined, understood and harmonised between stakeholders. |
Verification | Completeness |
Examples/Notes | Example: Standardised information exchange models such as the Aeronautical Information Exchange Model (AIXM) [RD10], the Flight Information Exchange Model (FIXM) [RD 11], the Weather Information Exchange Model (WXXM) [RD 13] and the ICAO Meteorological Information Exchange Model (IWXXM) [RD 14]. Example: Descriptions of information exchanged by services.
Example: Data catalogues used to list details on the exchanged information.
Example: Information exchanges captured as part of a business process model. |
Level of Implementation | Mandatory |
Guidance
- Provide all definitions as part of the definitions section and link to them as convenient.
Exchanged information is “information that is shared between actors in the ATM Network”.
Documented means that the exchange information is represented in a formalised form such as XML Schema or a data catalogue.
An information definition is “a formal representation of information concepts or data concepts”.
Types of information definitions
- Disambiguate from the examples section. The following are types of Information definitions.
- It could be convenient to provide links to existing information definitions (external references, see AIXM examples)
Data Catalogue
UML Model
Exchange Model
Verification Support
Completeness:
Check that:
- There is an information definition.
- The information definition covers all of the information that is exchanged between the actors.
Notes:
- The information definition can be a standalone document or embedded into another document such as a service description. (A set of documents can be provided instead of a single one)
Examples/Best Practice
- Need to agree a format for the examples and a source four the definitions used. The strawman uses ISO 19115 and 19139. Is this acceptable?
Examples of complete information definitions are given at xxxAdd list of examples e.g. ED-254, AIXM, etc.
