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. (Excerpt from Wikipedia article: XML Schema)

XHTML (eXtensible HyperText Markup Language) is a family of XML markup languages that mirror or extend versions of the widely-used Hypertext Markup Language (HTML), the language in which web pages are written. (Excerpt from Wikipedia article: XHTML)

Microsoft Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Microsoft first introduced an operating environment named Windows on November 20, 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Microsoft Windows came to dominate the world's personal computer market, overtaking Mac OS, which had been introduced in 1984. As of October 2009, Windows had approximately 91% of the market share of the client operating systems for usage on the Internet. The most recent client version of Windows is Windows 7; the most recent server version is Windows Server 2008 R2; the most recent mobile OS version is Windows Phone 7.

In computer software, a widget engine is a software service available to users for running and displaying applets on a graphical user interface, such as that of the desktop. The widget model in widget engines is attractive because of ease of development. Most of these widgets can be created with a few images and about 10 to several hundred lines of XML / JavaScript / VBScript source code. A single host software system, such as a web browser, runs all the loaded widgets. This allows several desktop widgets to be built sharing resources and code. The term widget engine is not to be confused with that of a widget toolkit. Toolkits are used by GUI programmers, who combine several widgets to form a single application. A widget in a toolkit provides a single, low level interaction, and is prepared to communicate with other widgets in the toolkit. On the other hand, widget engines such as desktop widgets and web widgets are intended for end users. Desktop and web widgets are stand-alone, task-oriented applications which can be composed of several related interactions on its own. Each widget serves only a purpose that is usually addressed by the effort of one GUI widget in a full-scale application. (Excerpt from Wikipedia article: Widget engine)

A web service is a method of communication between two electronic devices over a network. The W3C defines a "web service" as "a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically Web Services Description Language WSDL). Other systems interact with the web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards." The W3C also states, "We can identify two major classes of web services, REST-compliant Web services, in which the primary purpose of the service is to manipulate XML representations of Web resources using a uniform set of "stateless" operations; and arbitrary Web services, in which the service may expose an arbitrary set of operations.

A web portal or links page is a web site that function as a point of access to information on the World Wide Web. A portal presents information from diverse sources in a unified way. (Excerpt from Wikipedia article: Web portal)

A web browser or Internet browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content. Hyperlinks present in resources enable users to easily navigate their browsers to related resources. Although browsers are primarily intended to access the World Wide Web, they can also be used to access information provided by Web servers in private networks or files in file systems. Some browsers can also be used to save information resources to file systems. (Excerpt from Wikipedia article: web browser)

The term Web 2.0 is associated with web applications that facilitate participatory information sharing, interoperability, user-centered design, and collaboration on the World Wide Web. A Web 2.0 site allows users to interact and collaborate with each other in a social media dialogue as creators (prosumers) of user-generated content in a virtual community, in contrast to websites where users (consumers) are limited to the passive viewing of content that was created for them. Examples of Web 2.0 include social networking sites, blogs, wikis, video sharing sites, hosted services, web applications, mashups and folksonomies. The term is closely associated with Tim O'Reilly because of the O'Reilly Media Web 2.0 conference in late 2004. Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specification, but rather to cumulative changes in the ways software developers and end-users use the Web.

The Wayback Machine is a digital time capsule created by the Internet Archive non-profit organization, based in San Francisco, California. It is maintained with content from Alexa Internet. This service enables users to see archived versions of web pages across time - what the Archive calls a "three dimensional index." Internet Archive bought the domain waybackmachine.org for their own site. It is currently in beta test. (Excerpt from Wikipedia article: Wayback Machine)

VuFind is an open source library search engine that allows users to search and browse beyond the resources of a traditional OPAC. Developed by Villanova University, version 1.0 was released in July 2010 after two years in beta. VuFind operates with a simple, Google-like interface and offers flexible keyword searching. While most commonly used for searching catalog records, VuFind can be extended to search other library resources including but not limited to: locally cached journals, digital library items, and institutional repository and bibliography. The software is also modular and highly configurable, allowing implementers to choose system components to best fit their needs. As of March 2012, a total of 64 institutions are running live instances of Vufind including the Georgia Tech Library, the London School of Economics, the National Library of Ireland, Yale University, and the DC Public Library.

A virtual learning environment (VLE) is a system designed to support teaching and learning in an educational setting, as distinct from a Managed Learning Environment (MLE), where the focus is on management.A VLE will normally work over the Internet and provide a collection of tools such as those for assessment (particularly of types that can be marked automatically, such as multiple choice), communication, uploading of content, return of students' work, peer assessment, administration of student groups, collecting and organizing student grades, questionnaires, tracking tools, etc. New features in these systems include wikis, blogs, RSS and 3D virtual learning spaces. VLEs are often used in schools and other educational establishments in order to make the learning experience more interactive. While originally created for distance education, VLEs are now most often used to supplement traditional face to face classroom activities, commonly known as Blended Learning. These systems usually run on servers, to serve the course to students Multimedia and/or web pages. (Excerpt from Wikipedia article: Virtual learning environment)

A virtual research environment (VREs) or virtual laboratory is an online system helping researchers collaborate. Features usually include collaboration support (forums and wikis), document hosting, and some discipline-specific tools, such as data analysis, visualisation, or simulation management. In some instances, publication management, and teaching tools such as presentations and slides may be included. VREs have become important in fields where research is primarily carried out in teams which span institutions and even countries: the ability to easily share information and research results is valuable. The concept of the VRE was studied by UK funding agency JISC in 2010 which highlighted issues such as researcher involvement in VRE design, sustainability, and consideration of the project as primarily one of community building rather than technology. The report also noted synonyms such as "collaborative e-research community", "collaboratory" and "virtual research community". JISC funded development of a number of VREs under its "Virtual research environment programme" from 2004 to 2011. In Australia, e-Research body NeCTAR has funding for a "virtual laboratory" program to be allocated in 2011. (Excerpt from Wikipedia article: Virtual research environment)
