2. AIXM 4.5
EUROCONTROL's Efforts with AIXM

3. Why necessary Additional constraints on values of properties
Based on ICAO standards and recommended practices
Based on local practices
Based on common sense
Etc.
Objective
Identify non-compliance with rules
Identify potentially incorrect data
Prevent automated systems from receiving unexpected values
EUROCONTROL's Efforts with AIXM

4. AIXM 5.1 Business rules Detached from the model itself
Because they are dynamic
Because they are system specific
Business rules for AIXM 4.5 must be adapted to AIXM 5.1 as data provider systems will gradually move towards AIXM 5
AIXM 5 does no longer specify mandatory properties or associations for a feature.
Now to be specified as business rules
Opportunity to capture more rules from existing standards
EUROCONTROL's Efforts with AIXM

5. AIXM 5.1 Business rules Current status:
Defined a draft set of AIXM 5.1 business rules based on:
AIXM 4.5 business rules
ICAO Annex 10, 11, 14 and 15 and the ICAO PANS-OPS
Temporality Concept document (including PropertiesWithSchedule)
Activation/Usage concept
AIXM GML Guidelines
Arinc424-A specification
Compliance with SVBR v1.0 specification
Provided as a proof-of-concept an implementation of these rules in Schematron language
Upgraded Eurocontrol’s tool ARC which performs Schematron validation of AIXM data

6. SBVR specification
SBVR = Semantics of Business Vocabulary and Business Rules
defines the vocabulary and rules for documenting the semantics of business vocabularies, business facts, and business rules.
It identifies two types of business rules
Structural rules
Operative rules
AIXM 5 has adopted this terminology and identifies the following business rules:
AIXM Structural rules: the enumerations of values (datatypes)
AIXM Operative rules: rules extracted from official documents (ICAO Annexes), minimum data rules, consistency rules, recommended practices, coding rules…

7. Applying SVBR in an AIXM 5.1 context
Structural Rules
AIXM 5.1 UML
AIXM 5.1 XML
Airport features
AIXM 5.1 XSD
How to encode these rules ?
Syntactic check
Semantic check
Operative Rules

8. 1st AIXM 5.1 Business Rules Report
A contract was awarded in December 2009.
The result of this work is an Excel report
Containing textual rules classified by type etc…
Providing Schematron code
AIXM Users are able to pick-up the rules they need for their systems

10. AIXM 5.1 implementation in EAD
Need to consolidate the initial set of AIXM 5.1 Business Rules
Progressive refinement, in parallel with the implementation
Bring together
AIXM 5.1 draft business rules
Digital NOTAM specific rules (see Event Specification)
Other EAD specific data verification rules
Eurocontrol has decided to reuse a tool developed by Pulsar Consulting (BRM)
