Specs
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 at the foot of this page.
​
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 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.

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

Informative documentS
AMWA Informative Documents (documents with the prefix INFO) are not AMWA Specifications but contain information that is thought to be helpful to the media industry. For example, INFO-004 provides practical information on implementation of DNS-SD in NMOS systems and INFO-005 provides a guide for those implementing NMOS Controllers.
​
The information they contain is not required in order to successfully create an interoperable implementation of an AMWA Specification. That said, Informative documents are likely to be useful to implementers and end users who are working to create NMOS-based systems by identifying and addressing common questions and expanding on the normative language of the relevant Specifications.
​
Because Information Documents provide general information that may be helpful, but do not contain any normative provisions which would be required to ensure the implementation and interoperability of an AMWA Specification, the AMWA IPR Policy and procedures do not apply to them.
At the request of the AMWA board, a team of volunteers, including end-users, network equipment providers, processing equipment providers, and related software subsystem developers was charged with the task of adding a layer of detail to the JT-NM reference architecture in the area of control, monitoring and management interfaces.

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)
Data Model Specifications
The data models lie at the heart of the media workflow technologies.
Interface Specifications
The interface specifications are used to create interoperation between equipment and applications in the media workflow.
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.
