- Information (that is the "what" is exchanged)
- Information Elements (E.g. Aeronautical Information Features)
- Interaction (that specify how information is exchanged)
- Information Exchange Initiation ( E.g. whenever required by information consumer, whenever information changes,... )
- Information Exchange Frequency (E.g. Monthly in accordance with AIRAC )
- Filtering
- Non Functional Requirements
- Integrity required for the information exchanged
- Confidentiality of the information exchanged
- Constraints (additional considerations that influence the exchange of information)
- Technical Constraints (E.g. AIXM)
