Richard (Rick) Alan Jelliffe (born 1960) is an Australian programmer and standards activist (ISO, W3C, IETF), particularly associated with web standards, markup languages, internationalization and schema languages. He is the founder and Chief Technical Officer of Topologi Pty. Ltd, an XML tools vendor in Sydney. He has a degree in economics from the University of Sydney.
Jelliffe is the inventor of the Schematron schema language; its core idea of using XPath to state constraints has been widely adopted and adapted. He is the editor of the ISO International Standard 19757-3 Document Schema Definition Languages – Part 3: Path Based Rule Languages (Schematron).
In 1999-2001 Jelliffe worked at Academia Sinica, Taipei, Taiwan. The Chinese XML Now! website provides Chinese and English information and test files on XML. Jelliffe has also made an English/Chinese multilingual typesetting system used to publish PRC trade laws. He has been an invited expert on Internationalization to the W3C.
In January 2007, Microsoft "technical evangelist" Doug Mahugh asked Jelliffe to correct English Wikipedia articles about some of the standardization efforts in which he was involved, including Ecma Office Open XML and OpenDocument, suggesting that Microsoft could pay him for the time he spent editing English Wikipedia. Jelliffe commented on the offer in his blog and this led to international press coverage. [1] [2] [3]
The controversial decision by Standards Australia to include Jelliffe on its delegation to the vote at the ISO on standardisation of Ecma International's Office Open XML document format was widely criticised. Some considered Jelliffe too close to Microsoft to be impartial. [4] [5]
Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing arbitrary data. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML.
The Organization for the Advancement of Structured Information Standards is a nonprofit consortium that works on the development, convergence, and adoption of projects - both open standards and open source - for Computer security, blockchain, Internet of things (IoT), emergency management, cloud computing, legal data exchange, energy, content technologies, and other areas.
XSD, a recommendation of the World Wide Web Consortium (W3C), specifies how to formally describe the elements in an Extensible Markup Language (XML) document. It can be used by programmers to verify each piece of item content in a document, to assure it adheres to the description of the element it is placed in.
X3D is a set of royalty-free ISO/IEC standards for declaratively representing 3D computer graphics. X3D includes multiple graphics file formats, programming-language API definitions, and run-time specifications for both delivery and integration of interactive network-capable 3D data. X3D version 4.0 has been approved by Web3D Consortium, and is under final review by ISO/IEC as a revised International Standard (IS).
REgular LAnguage description for XML (RELAX) is a specification for describing XML-based languages. A description written in RELAX is called a RELAX grammar.
In computing, RELAX NG is a schema language for XML—a RELAX NG schema specifies a pattern for the structure and content of an XML document. A RELAX NG schema is itself an XML document but RELAX NG also offers a popular compact, non-XML syntax. Compared to other XML schema languages RELAX NG is considered relatively simple.
Document Schema Definition Languages (DSDL) is a framework within which multiple validation tasks of different types can be applied to an XML document in order to achieve more complete validation results than just the application of a single technology.
Schematron is a rule-based validation language for making assertions about the presence or absence of patterns in XML trees. It is a structural schema language expressed in XML using a small number of elements and XPath languages. In many implementations, the Schematron XML is processed into XSLT code for deployment anywhere that XSLT can be used.
Vector Markup Language (VML) is an obsolete XML-based file format for two-dimensional vector graphics. It was specified in Part 4 of the Office Open XML standards ISO/IEC 29500 and ECMA-376. According to the specification, VML is a deprecated format included in Office Open XML for legacy reasons only.
The Open Document Format for Office Applications (ODF), also known as OpenDocument, standardized as ISO 26300, is an open file format for word processing documents, spreadsheets, presentations and graphics and using ZIP-compressed XML files. It was developed with the aim of providing an open, XML-based file format specification for office applications.
An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints.
Ecma International is a nonprofit standards organization for information and communication systems. It acquired its current name in 1994, when the European Computer Manufacturers Association (ECMA) changed its name to reflect the organization's global reach and activities. As a consequence, the name is no longer considered an acronym and no longer uses full capitalization.
Various binary formats have been proposed as compact representations for XML. Using a binary XML format generally reduces the verbosity of XML documents thereby also reducing the cost of parsing, but hinders the use of ordinary text editors and third-party tools to view and edit the document. There are several competing formats, but none has yet emerged as a de facto standard, although the World Wide Web Consortium adopted EXI as a Recommendation on 10 March 2011.
Office Open XML is a zipped, XML-based file format developed by Microsoft for representing spreadsheets, charts, presentations and word processing documents. Ecma International standardized the initial version as ECMA-376. ISO and IEC standardized later versions as ISO/IEC 29500.
Makoto Murata is a Japanese computer scientist, Ph.D. in engineering, and Project Professor at Keio University.
The Open Packaging Conventions (OPC) is a container-file technology initially created by Microsoft to store a combination of XML and non-XML files that together form a single entity such as an Open XML Paper Specification (OpenXPS) document. OPC-based file formats combine the advantages of leaving the independent file entities embedded in the document intact and resulting in much smaller files compared to normal use of XML.
The Office Open XML file formats, also known as OOXML, were standardised between December 2006 and November 2008, first by the Ecma International consortium, and subsequently, after a contentious standardization process, by the ISO/IEC's Joint Technical Committee 1.
XPath is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) in 1999, and can be used to compute values from the content of an XML document. Support for XPath exists in applications that support XML, such as web browsers, and many programming languages.
This is a comparison of the Office Open XML document file format with the OpenDocument file format.
The Office Open XML file formats are a set of file formats that can be used to represent electronic office documents. There are formats for word processing documents, spreadsheets and presentations as well as specific formats for material such as mathematical formulas, graphics, bibliographies etc.
