This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document.
W3C Recommendations have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the W3C Recommendation Track.
Group Notes are not standards and do not have the same level of W3C endorsement.
This specification describes the syntax and semantics of XProc: An XML Pipeline Language, a language for describing operations to be performed on XML documents.
An XML Pipeline specifies a sequence of operations to be performed on zero or more XML documents. Pipelines generally accept zero or more XML documents as input and produce zero or more XML documents as output. Pipelines are made up of simple steps which perform atomic operations on XML documents and constructs similar to conditionals, iteration, and exception handlers which control which steps are executed.
The XProc step library defines names and characteristics for a set of pipeline steps that every XProc processor is expected to support, as well as additional optional steps.
XProc is an XML pipeline language; that is, a declarative dataflow language used to express steps required to process XML documents, coordinating operations such as querying, validation, inclusion, transformation and sorting.
This specification defines several XML processor profiles, each of which fully determines a data model for any given XML document.
This document defines two new, optional templates designed to make it easier to construct documents within an XProc pipeline using values computed by that pipeline.
This document contains requirements for the development of XML Processing Model and Language, which are intended to describe and specify the processing relationships between XML resources.
Below are draft documents: other Working Drafts . Some of these may become Web Standards through the W3C Recommendation Track process. Others may be published as Group Notes or become obsolete specifications.
This document contains requirements on the development of XProc: An XML Pipeline Language Version 2.0. These requirements are focused primarily on making the language simpler and easier to use.
