The World Wide Web Consortium (W3C) has released XProc, an Extensible Markup Language (XML) pipeline specification for managing XML-rich processes. W3C says the specification "provides a standard framework for composing XML processes [and] streamlines the automation, sequencing, and management of complex computations involving XML."
XML is used throughout enterprise computing environments because it provides a standard way to manipulate data. "What we haven't had is any standard way to describe how to combine [XML functions] to accomplish any particular task," says XProc specification co-editor Mark Logic. "That's what XProc provides."
University of Edinburgh's Henry Thomas, co-editor of the XProc specification, says "XProc exemplifies what W3C does best: We looked at existing practice—people have been using a number of similar-but-different XML-based languages—and we produced a consensus standard, creating interoperability and critical mass."
W3C notes that XProc features a test suite that covers all of the required and optional steps of the language as well as all the static and dynamic errors.
