DOM Level 2 became a W3C Recommendation in November 2000, and is composed of five specifications:

DOM2 Core Specification

http://www.w3.org/TR/DOM-Level-2-Core/

DOM2 Views Specification

http://www.w3.org/TR/DOM-Level-2-Views/

DOM2 Events Specification

http://www.w3.org/TR/DOM-Level-2-Events/

DOM2 Style Specification

http://www.w3.org/TR/DOM-Level-2-Style/

DOM2 Traversal and Range Specification

http://www.w3.org/TR/DOM-Level-2-Traversal-Range/

Work on DOM Level 3 is in progress. More information on DOM Level 3 (which notably adds XPath and Load and Save support) is available at http://www.w3.org/DOM/.

Description

DOM Level 2 is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content and structure of documents. The DOM Level 2 Core builds on the DOM Level 1 Core, and consists of a set of core interfaces that create and manipulate the structure and contents of a document. The Core also contains specialized interfaces dedicated to XML.

Status

SAX was collaboratively developed by the XML-DEV mailing list (hosted by OASIS). The current release is SAX 2.0, dated May 2000. SAX is maintained by David Brownell at http://www.saxproject.org/.

Description

SAX2 is an event-based API. SAX2 introduces configurable features and properties and adds support for XML Namespaces. It also includes adapters that allow it to interoperate with SAX1 parsers and applications.

Status

Canonical XML was collaboratively developed by the W3C and IETF. There are two current Recommendations: the March 2001 Canonical XML 1.0, at http://www.w3.org/TR/xml-c14n, and the July 2002 Exclusive XML Canonicalization Version 1.0, at http://www.w3.org/TR/xml-exc-c14n.

Description

Canonical XML is designed to remove all the syntactical variations of XML documents and produce a single representation which can be used reliably for tasks like checksums and signatures.

Status

XML Signature was collaboratively developed by the W3C and IETF. The February 2002 XML-Signature Syntax and Processing is published at http://www.w3.org/TR/xmldsig-core/.

Description

XML Signature is designed to provide unique identifiers for XML documents which can then be used in other XML-based projects, notably security projects.
