GraphML is an XML-based file format for graphs. The GraphML file format results from the joint effort of the graph drawing community to define a common format for exchanging graph structure data. It uses an XML-based syntax and supports the entire range of possible graph structure constellations including directed, undirected, mixed graphs, hypergraphs, and application-specific attributes. [1]
A GraphML file consists of an XML file containing a graph
element, within which is an unordered sequence of node
and edge
elements. Each node
element should have a distinct id
attribute, and each edge
element has source
and target
attributes that identify the endpoints of an edge by having the same value as the id
attributes of those endpoints. Here is what a simple undirected graph with two nodes and one edge between them looks like:
<?xml version="1.0" encoding="UTF-8"?><graphmlxmlns="http://graphml.graphdrawing.org/xmlns"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd"><graphid="G"edgedefault="undirected"><nodeid="n0"/><nodeid="n1"/><edgeid="e1"source="n0"target="n1"/></graph></graphml>
Additional features of the GraphML language allow its users to specify whether edges are directed or undirected, and to associate additional data with vertices or edges.
A document type definition (DTD) is a specification file that contains set of markup declarations that define a document type for an SGML-family markup language. The DTD specification file can be used to validate documents.
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.
Graphviz is a package of open-source tools initiated by AT&T Labs Research for drawing graphs specified in DOT language scripts having the file name extension "gv". It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.
DOT is a graph description language, developed as a part of the Graphviz project. DOT graphs are typically stored as files with the .gv
or .dot
filename extension — .gv
is preferred, to avoid confusion with the .dot
extension used by versions of Microsoft Word before 2007. dot
is also the name of the main program to process DOT files in the Graphviz package.
XML Linking Language, or XLink, is an XML markup language and W3C specification that provides methods for creating internal and external links within XML documents, and associating metadata with those links.
Graph Modeling Language (GML) is a hierarchical ASCII-based file format for describing graphs. It has been also named Graph Meta Language.
Catalogue Service for the Web (CSW), sometimes seen as Catalogue Service - Web, is a standard for exposing a catalogue of geospatial records in XML on the Internet. The catalogue is made up of records that describe geospatial data, geospatial services, and related resources.
In computer science and web development, XML Events is a W3C standard for handling events that occur in an XML document. These events are typically caused by users interacting with the web page using a device, such as a web browser on a personal computer or mobile phone.
Security Assertion Markup Language 2.0 (SAML 2.0) is a version of the SAML standard for exchanging authentication and authorization identities between security domains. SAML 2.0 is an XML-based protocol that uses security tokens containing assertions to pass information about a principal between a SAML authority, named an Identity Provider, and a SAML consumer, named a Service Provider. SAML 2.0 enables web-based, cross-domain single sign-on (SSO), which helps reduce the administrative overhead of distributing multiple authentication tokens to the user. SAML 2.0 was ratified as an OASIS Standard in March 2005, replacing SAML 1.1. The critical aspects of SAML 2.0 are covered in detail in the official documents SAMLCore, SAMLBind, SAMLProf, and SAMLMeta.
The Pronunciation Lexicon Specification (PLS) is a W3C Recommendation, which is designed to enable interoperable specification of pronunciation information for both speech recognition and speech synthesis engines within voice browsing applications. The language is intended to be easy to use by developers while supporting the accurate specification of pronunciation information for international use.
The Internationalization Tag Set (ITS) is a set of attributes and elements designed to provide internationalization and localization support in XML documents.
N-Triples is a format for storing and transmitting data. It is a line-based, plain text serialisation format for RDF graphs, and a subset of the Turtle format. N-Triples should not be confused with Notation3 which is a superset of Turtle. N-Triples was primarily developed by Dave Beckett at the University of Bristol and Art Barstow at the World Wide Web Consortium (W3C).
Trivial Graph Format (TGF) is a simple text-based adjacency list file format for describing graphs, widely used because of its simplicity.
Animation of Scalable Vector Graphics, an open XML-based standard vector graphics format is possible through various means:
EPUB is an e-book file format that uses the ".epub" file extension. The term is short for electronic publication and is sometimes stylized as ePUB. EPUB is supported by many e-readers, and compatible software is available for most smartphones, tablets, and computers. EPUB is a technical standard published by the International Digital Publishing Forum (IDPF). It became an official standard of the IDPF in September 2007, superseding the older Open eBook (OEB) standard.
PhyloXML is an XML language for the analysis, exchange, and storage of phylogenetic trees and associated data. The structure of phyloXML is described by XML Schema Definition (XSD) language.
The Web Services Description Language is an XML-based interface description language that is used for describing the functionality offered by a web service. The acronym is also used for any specific WSDL description of a web service, which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns. Therefore, its purpose is roughly like a type signature in a programming language.
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.
Directed Graph Markup Language (DGML) is an XML-based file format for directed graphs.
The SAML metadata standard belongs to the family of XML-based standards known as the Security Assertion Markup Language (SAML) published by OASIS in 2005. A SAML metadata document describes a SAML deployment such as a SAML identity provider or a SAML service provider. Deployments share metadata to establish a baseline of trust and interoperability.
