FIXM_Core_v4_0_0_Primer_20161031.pdf  

The FIXM Primer is the entry point to FIXM. It provides an introduction to FIXM, sets it into context, explains how the FIXM community is organized, and lists its components and supporting materials.

FIXM_Core_v4_0_0_Logical_Model.eap  

The attached Logical Model "FIXM_Core_v4_0_0_Logical_Model.eap" describes the structure, content, and format of FIXM v4.0.0 Core represented as a Universal Modelling Language (UML) model. The attached document "FIXM_Core_v4_0_0_Logical_Model_Diagrams.pdf" contains images of the various classes contained in the UML files. Please note the Sparx Systems Enterprise Architect Viewer is required to view the UML model, which can be downloaded from http://www.sparxsystems.com.

FIXM_Core_v4_0_0_Modelling_Best_Practices.pdf  

The FIXM Modelling Best Practices specifies the procedures and best practices used to produce FIXM logical models. It is required that all logical models sponsored by the FIXM organization comply with these practices, to ensure that the models are complete, correct, and efficient. It is strongly suggested that all extension data models adhere to these best practices, to ensure proper interoperation with the FIXM core models.

Please note that this document was referred to as the "FIXM Modeller Manual" in previous releases.

FIXM_Core_v4_0_0_Operational_Data_Description_20161031.pdf  

The FIXM v4.0.0 Operational Data Description serves as a catalogue of flight data elements (FDEs) that are expected to be exchanged using the FIXM standard. It provides a definition for those FDEs, as well as alternate names that reflect various nomenclatures across systems and domains, relationships among FDEs, data types, value ranges (where applicable), business rules associated with the individual use of each FDE, and references to authoritative documents where the FDEs can be found. This document is complementary to the other FIXM artifacts such as the FIXM models and the FIXM schemas. The Operational Data Description is primarily intended as a reference for the FIXM CCB and development team, as its entries are not a one-for-one match to the Logical Model or Schema. FIXM users are encouraged to use the Schema Documentation provided above for details on the individual data elements in the final FIXM release.

The FIXM Core v4.0.0 was released on August 31, 2016. This release supports the content of the individual ATS message fields described in ICAO Doc 4444 and the new flight data items identified by ICAO ATMRPP as part of the requirements for FF-ICE Block 1. This version of FIXM:

• Retains only the pieces of flight information that are traceable to ICAO requirements (Doc 4444 and draft FF-ICE Block 1 requirements). This implies that some capabilities previously enabled by FIXM are no longer supported.
• Incorporates a new messaging package for enabling the creation of the FF-ICE Block 1 messages as described by ICAO ATMRPP.
• Implements improved route and 4DT structures in line with FF-ICE Block 1 requirements.
• Achieves greater alignment with ISO standards (e.g. ISO 19103) and AIXM 5.1.

FIXM v4.0.0 is not backward compatible with FIXM v3.0.1.

UPDATE - October 31^st, 2016:

Complementary material was released on October 31^st, 2016. This package does not affect the FIXM Core v4.0.0 XML Schemas nor the Logical Model. The objective of this complementary material is to improve the documentation of the FIXM Core v4.0.0 release by updating some of the documentation components and introducing new ones.

• FIXM Core v4.0.0 Primer
  Updated on October 31^st, 2016, to add the hyperlinks for the updated complementary materials.
• FIXM Modeling Best Practices
  Released on October 31^st, 2016.
• FIXM Core v4.0.0 Operational Data Description
  Updated on October 31^st, 2016. The updated edition adds the tracing of the data elements to the ICAO FF-ICE Implementation Guidance and the UML paths to the FIXM Logical Model elements.
