This document is part 1 of the specification of the Application Level Events (ALE) interface, through which clients may interact with filtered, consolidated electronic product code (EPC) data and related data from a variety of sources. The role of the ALE interface is to provide independence between the infrastructure components that acquire the raw EPC data, the architectural components that process the data, and the applications that use the processed data. This document specifies all interfaces that are part of the ALE specification using unified modelling language (UML) notation. Part 2 of the specification specifies XML-based wire protocol bindings of the interfaces.

Main sections:

• Role within the EPCglobal network architecture

• Terminology and typographical conventions

• ALE interfaces

• ALE concepts and principles of operation

• Built-in fieldnames, datatypes and formats

• Tag memory specification API

• ALE reading API

• ALE writing API

• ALE logical reader API

• Access control API

• Use cases (non-normative)

• ALE scenarios (non-normative)
