∠, the angle symbol in Unicode is List of XML and HTML character entity references | U + 2220

Berkeley DB is also used as the common name for three distinct products ; Oracle Berkeley DB, Berkeley DB Java Edition, and Berkeley DB XML.

DB XML is written in C ++ and supports multiple language bindings, including C ++, Java ( via JNI ), Perl and Python.

XHTML, which is an XML application, supports the HTML entity set, along with XML's predefined entities.

XQuery is an XML based database language ( also named XQL ).

A Document Type Definition ( DTD ) is a set of markup declarations that define a document type for an SGML-family markup language ( SGML, XML, HTML ).

A DTD is associated with an XML or SGML document by means of a Document Type Declaration.

( Notations declared in the DTD are also referencing external entities, but these unparsed entities are not needed for the validation of documents in the standalone mode of these parsers: the validation of all external entities referenced by notations is left to the application using the SGML or XML parser ).

However this behaviour is application-specific, and requires that the application maintains a catalog of known URNs to resolve them into the notations that have been parsed in a standard SGML or XML parser.

The XML DTD syntax is one of several XML schema languages.

In addition, documents for these XML schema languages have to be parsed separately, so validating the schema of XML documents in pure standalone mode is not really possible with these languages: the document type declaration remains necessary for at least identifying ( with a XML Catalog ) the schema used in the parsed XML document and that will be validated in another language.

In the example below, the XML document is declared with because it has an external subset in its document type declaration:

If the XML document type declaration includes any SYSTEM identifier for the external subset, it can't be safely processed as standalone: the URI should be retrieved, otherwise there may be unknown named character entities whose definition may be needed to correctly parse the effective XML syntax in the internal subset or in the document body ( the XML syntax parsing is normally performed after the substitution of all named entities, excluding the five entities that are predefined in XML and that are implicitly substituted after parsing the XML document into lexical tokens ).

However, many browsers do not check that an XML document conforms to the rules in the DTD ; they are only required to check that the DTD is syntactically correct.

* XML Schema, also referred to as XML Schema Definition ( XSD ), has achieved Recommendation status within the W3C, and is popular for " data oriented " ( that is, transactional non-publishing ) XML use because of its stronger typing and easier round-tripping to Java declarations.

De Icaza endorsed Microsoft's Office Open XML ( OOXML ) document standard, disagreeing with a lot of the widespread criticism in the open source and free software community.

XML was chosen as the standard message format because of its widespread use by major corporations and open source development efforts.

These communicate using XML / SOAP via port 80, which is normally left open or filtered through a HTTP proxy inside the organization, for web browsing via HTTP.

Xalan is a popular open source software library from the Apache Software Foundation, originally created by IBM under the name LotusXSL, that implements the XSLT 1. 0 XML transformation language and the XPath 1. 0 language.

* Introduction to GlossML This article presents Glossary Markup Language ( GlossML ), an open XML vocabulary specially designed to facilitate the exchange of glossaries.

* James Clark ( programmer ) ( born 1964 ), author of groff and expat, who has done much work with open software and XML

* oBIX — open Building Information Exchange, an extensible XML specification for enterprise interaction with building-based ( or other ) control systems, including HVAC, Access Control, Intrusion Detection, and many others.

It is a distributed, open architecture protocol based on established standards such as the Internet Protocol Suite ( TCP / IP ), HTTP, XML, and SOAP.

As JXTA is based upon a set of open XML protocols, it can be implemented in any modern computer language.

X3D also benefits from other open source standards like XML, DOM and XPath.

This is as opposed to SAX which streams XML events such as " open element " " close element " " text node " ( and so on ) so that other software that can begin interpreting these immediately -- before the end of the file is reached.

* The protocol is open and based upon standardized XML communication over HTTP POST which makes it relatively straightforward to implement on any platform.

Examples of XML-based open standards are DocBook, XHTML, and, more recently, the ISO / IEC standards OpenDocument ( ISO 26300: 2006 ) and Office Open XML ( ISO 29500: 2008 ).

* OpenOffice. org XML —. sxw ( open, XML-based format for office documents )

The trend in the increase of XML and YAML ( among other formats ) for use as configuration-file formats is at least partially attributable to the increase in popularity of open source and platform neutral software applications and libraries.

* Open eSignForms is open source ( AGPL ) web-based electronic signature software secured with standard XML Digital Signatures

One of these trends is the combination of greater data collection ( more sensors ), greater and more automated data exchange ( via building new, open industry-standard XML schemas ), and data mining to yield a new level of business intelligence and workflow automation in manufacturing.

He made significant contributions to other open source software projects including FlightGear, a cross-platform flight simulator making use of XML, the NewsML Toolkit library for NewsML, the XMLWriter libraries for Perl and Java, RDF Filter, and SGMLSpm, a mid-1990s precursor to many XML functionalities.

o: XML is an open source, dynamically typed, general-purpose object-oriented programming language based on XML-syntax.

* Open XML Paper Specification ( XPS or OpenXPS ), an open royalty-free fixed-layout document format developed by Microsoft

Users can get up to speed quickly on the most critical technologies affecting their profession, like open, industry-standard technologies such as Java, Linux, SOA and web services, web development, Ajax, PHP, and XML, as well as learn about IBM's software products ( WebSphere, Rational, Lotus, Tivoli and DB2 ).

YafaRay is a free, open source ray tracing program that uses an XML scene description language.

* Graffiti Markup Language, a specifically formated XML file designed to be a common open structure for archiving gestural graffiti motion data into a text file

The content, apart from insolvency notices, is available in a number of machine-readable formats, including XML ( delivery by email / FTP )

Tools generate localised and internationalised HTML, ePub, or PDF human-readable output and DTDs, W3C XML Schema, Relax NG Compact Syntax, or Relax NG XML Syntax machine-readable output.
