Agenda• What is our Vision?• Information Service Reference Model• What is Modularity?• Why?• Proposal

2

What is our Vision?• Practitioners at all levels of aviation share

accurate, complete, timely and appropriately secured information to ensure public safety.

• To produce “exchange schemas” which offer a high degree of clarity, interoperability and reusability while being agnostic to the actual deployment software tools.

• Alignment to domain data model components dictionary – interoperability across domain applications.

What is Modularity?• From Wikipedia, “Modular design is an approach

that subdivides a system into smaller parts (modules) that can be independently created and then used in different systems to drive multiple functionalities. Improve maintainability by enforcing logical boundaries between components”.

5

Why?• Encourages reuse by creating well-defined modules

that perform a particular task• Increases flexibility and maintainability because

single modules can be upgraded or replaced independently of others

• Eases development, testing, and maintenance by providing a logical, easy to understand, and consistent organization

6

Proposal• Encapsulate Features and Usage • Generate XSD by Subject Area/Domain data model

components • Evaluate Reorganizing Packages– Common XML features XML Schema are XML

documents themselves and therefore share many aspects of the languages they define.
