This article presents a comparison of digital image metadata viewers and metadata editors.
A metadata editor is a computer program that allows users to view and edit metadata tags interactively on the computer screen and save them in the graphics file. Usually a metadata viewer is preferred over a metadata editor for viewing tags.
A number of metadata editors for various platforms exist. Users choose among them based on factors such as the availability for the user's platform, the feature set and usability of the user interface (UI).
The Metadata Working Group (MWG) is a consortium of leading companies in the digital media industry. The MWG publishes technical specifications that describe how to effectively store metadata into digital media files. These royalty-free specifications are made available to software developers, manufacturers and service providers so that they may create products that use metadata in a consistent way, and that allow consumers to better describe, organize and find their media. Where possible, these specifications rely on existing standards, and aim to create a unified and cohesive approach to applying these standards.
