SPECIFICATIONS

The AMWA develops specifications and technologies to facilitate the deployment and operation of efficient media workflows. There are three types of specifications - Application Specifications, Data Model Specifications, and Interface Specifications. The AMWA also publishes Best Current Practices. More information on each of these document types is provided below.

To make sure that projects are clearly defined, adequately resourced and successful, we have a process to carefully manage proposals from start to finish. We welcome all new ideas to advance workflows. The AMWA Specification Process document (see link below) provides information on how AMWA projects are started, the different types of AMWA Specifications, and the different levels of AMWA Specifications.

Although first designed to meet a known requirement, a specification can be updated, either because the original user has refined their needs or because a new member wishes to capitalise on the previous work and slightly extend the capabilities of the specification.

Application Specifications
Applications Specifications define a set of rules that constrain a standard—like MXF—to suit a specific application. Each has been created to satisfy the clearly defined operational need of a member company.
  • Program Mastering when there are multiple versions of the content (AS-02)

  • Program Delivery to multiple broadcast stations (AS-03)

  • Archive and Preservation of a wide range of material (AS-07)
  • Workflows suited to fast turnaround end-to-end production (AS-10)

  • Media Contribution for the delivery of finished media assets to a broadcaster or publisher (AS-11)

  • The use of metadata for the management of content, including a unique identifier (AS-12)

Best Current Practices

Best current practices are intended to define and ratify the community's best current thinking on statements of principle or the best ways to perform certain operations or process functions.

This Best Current Practice (BCP) describes the AMWA’s Specification development process, including how work is initiated, levels of AMWA documents, and types of AMWA Specifications. The goals of the AMWA Specification process are 1) interoperability, 2) satisfying business needs, 3) technical robustness, 4) reusability and composability, and 5) timeliness.

This Best Current Practice (BCP) describes the AMWA's specification development process. This document is, itself, a Best Current Practice.
