This release contains the Primer, Schemas, Schema Documentation, Logical Model, Modelling Best Practices document, and the Operational Data Description (ODD).

FIXM_Core_v4_1_0_Primer.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_1_0_Schemas.zip  

The attached file "FIXM_Core_v4_1_0_Schemas.zip" contains the XML schema representation of the FIXM v4.1.0 Core in .xsd format.

FIXM_Core_v4_1_0_Logical_Model.eap  

The attached Logical Model "FIXM_Core_v4_1_0_Logical_Model.eap" describes the structure, content, and format of FIXM v4.1.0 Core represented as a Universal Modelling Language (UML) model. The attached document "FIXM_Core_v4_1_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_1_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_1_0_Operational_Data_Description.pdf  

The FIXM v4.1.0 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.
