Single-Source Publishing

An authoring and publishing methodology where content is written and maintained in one master source and then automatically transformed into multiple output formats such as HTML, PDF, Braille, or mobile-optimized views. This approach is significant for accessibility because it ensures that accessible formatting can be built into the transformation process once, rather than requiring manual accessibility remediation for each output format. Single-source publishing reduces the cost of producing accessible alternatives and eliminates the common problem of "accessible versions" becoming outdated when the primary version is updated.
