This specification defines several XML processor profiles, each of which defines how any given XML document should be processed, both operationally and in terms of what information must be made available to applications. It is intended as a resource for other specifications, which can by a single normative reference establish precisely what input processing they require as well as what information they require.

This specification defines the 5th major revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features are introduced to help Web application authors, new elements are introduced based on research into prevailing authoring practices, and special attention has been given to defining clear conformance criteria for user agents in an effort to improve interoperability.

The ruby markup model currently described in the HTML specification is limited in its support for a number of features, notably jukugo and double-sided ruby, as well as inline ruby. This specification addresses these issues by introducing new elements and changing the ruby processing model. Specific care has been taken to ensure that authoring remains as simple as possible.This document was largely developed to address the shortcomings listed in Use Cases & Exploratory Approaches for Ruby Markup.

A document that uses polyglot markup is a document that is a stream of bytes that parses into identical document trees (with some exceptions, as noted in the Introduction) when processed either as HTML or when processed as XML. Polyglot markup that meets a well-defined set of constraints is interpreted as compatible, regardless of whether it is processed as HTML or as XHTML, per the HTML5 specification. Polyglot markup uses a specific DOCTYPE, namespace declarations, and a specific case—normally lower case but occasionally camel case—for element and attribute names. Polyglot markup uses lower…

This specification defines the 5th major version, first minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability.

The XMLHttpRequest specification defines an API that provides scripted client functionality for transferring data between a client and a server.

JSON is a useful data serialization and messaging format. This specification defines JSON-LD, a JSON-based format to serialize Linked Data. The syntax is designed to easily integrate into deployed systems that already use JSON, and provides a smooth upgrade path from JSON to JSON-LD. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Web services, and to store Linked Data in JSON-based storage engines.

This specification defines a set of algorithms for programmatic transformations of JSON-LD documents. Restructuring data according to the defined transformations often dramatically simplifies its usage. Furthermore, this document proposes an Application Programming Interface (API) for developers implementing the specified algorithms.

The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web. This document defines an XML syntax for RDF called RDF/XML in terms of Namespaces in XML, the XML Information Set and XML Base.

The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web. This document defines a textual syntax for RDF called Turtle that allows an RDF graph to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes. Turtle provides levels of compatibility with the N-Triples [N-TRIPLES] format as well as the triple pattern syntax of the SPARQL W3C Recommendation.

This specification defines the syntax and semantics of XSLT 3.0, a language for transforming XML documents into other XML documents. XSLT 3.0 is a revised version of the XSLT 2.0 Recommendation [XSLT 2.0] published on 23 January 2007. The primary purpose of the changes in this version of the language is to enable transformations to be performed in streaming mode, where neither the source document nor the result document is ever held in memory in its entirety. Another important aim is to improve the modularity of large stylesheets, allowing stylesheets to be developed from independently…

The Resource Description Framework (RDF) is a framework for representing information in the Web.This document defines a textual syntax for RDF called RDF/JSON that allows an RDF graph to be completely written in a form compatible with the JavaScript Object Notation (JSON) [RFC4627] and alternative to the one recommended in JSON-LD [JSON-LD].The syntax defined in this document should not be used unless there is a specific reason to do so. Use of JSON-LD is recommended.
