What is "mashup"

n. 1 (context computing slang English) A derivative work consisting of two pieces of (generally digital) media joined together, such as a video clip with a different soundtrack applied for humorous effect, or a map overlaid with user-supplied data. Websites allowing their information to be pulled in by other website creators to combine with other sources of information and create new user experiences. 2 (context music slang English) A remix that combines two or more songs from different artists into one track. 3 (context Internet English) a Web application that combines data and/or functionality from more than one source.

A mashup (also mesh, mash up, mash-up, blend, bootleg and bastard pop/rock) is a song or composition created by blending two or more pre-recorded songs, usually by overlaying the vocal track of one song seamlessly over the instrumental track of another. To the extent that such works are " transformative" of original content, they may find protection from copyright claims under the " fair use" doctrine of copyright law. Mashup - Creative blending of multiple songs/videos

Mashup may refer to:

• Mashup (music), the musical genre encompassing songs which consist entirely of parts of other songs
• Mashup (video), a video that is edited from more than one source to appear as one
• Mashup (book), a book which combines a pre-existing text, often a classic work of fiction, with a certain popular genre such as vampire or zombie narratives
• Mashup (web application hybrid), a web application that combines data and/or functionality from more than one source
• Mash-Up (Glee), a musical theater performance composed of integrated segments from other performances as popularized by the American television series Glee
• Mash Up (TV series), a television show on Comedy Central starring T.J. Miller.
• Lotus Mashups, a Business Mashups editor developed and distributed by IBM as part of the IBM Mashup Center system
• Band Mashups, the former name of the video game Battle of the Bands

A mashup, in web development, is a web page, or web application, that uses content from more than one source to create a single new service displayed in a single graphical interface. For example, a user could combine the addresses and photographs of their library branches with a Google map to create a map mashup. The term implies easy, fast integration, frequently using open application programming interfaces ( open API) and data sources to produce enriched results that were not necessarily the original reason for producing the raw source data. The term mashup originally comes from British - West Indies slang meaning to be intoxicated, or as a description for something or someone not functioning as intended. In recent English parlance it can refer to music, where people seamlessly combine audio from one song with the vocal track from another—thereby mashing them together to create something new.

The main characteristics of a mashup are combination, visualization, and aggregation. It is important to make existing data more useful, for personal and professional use. To be able to permanently access the data of other services, mashups are generally client applications or hosted online.

In the past years, more and more Web applications have published APIs that enable software developers to easily integrate data and functions the SOA way, instead of building them by themselves. Mashups can be considered to have an active role in the evolution of social software and Web 2.0. Mashup composition tools are usually simple enough to be used by end-users. They generally do not require programming skills and rather support visual wiring of GUI widgets, services and components together. Therefore, these tools contribute to a new vision of the Web, where users are able to contribute.

A video mashup (also written as video mash-up) combines multiple pre-existing video sources with no discernible relation with each other into a unified video. These are derivative works as defined by the United States Copyright Act , and as such, may find protection from copyright claims under the doctrine of fair use. Examples of mashup videos include movie trailer remixes, vids, YouTube Poop, and supercuts.

A mash-up novel (also called "mashup" or "mashed-up novel"), is a work of fiction which combines a pre-existing literature text, often a classic work of fiction, with another genre, such as horror genre into a single narrative. Marjorie Kehe of the Christian Science Monitor renders this admixture of classic text as "somewhere between 60 and 85 percent original text, with new plot twists added by contemporary co-authors". These "twists" often include horror fiction elements like vampires, werewolves or zombies.

Mashups are a combination of two or more data sources that have been integrated into one source. They typically consist of graphics, texts, audio clips, and video that have been sourced from various media such as blogs, wikis, YouTube, Google Maps, etc., into a new product. Remix is a related term, referring to how data sources have been combined to produce a constellation of elements that were not originally intended by the creators. Mashups rely on open and discoverable resources, open and transparent licensing, and open and remixable formats.

In the educational context, mashups are being used as an instructional tool by the teacher and/or as a product created by the student who are responsible for manipulating the data themselves. For example, http://rru.worldbank.org/businessplanet/, is a mashup website that was created by the World Bank to provide learners with data about country GDP, GDP growth, taxes, and other related information about countries around the globe. Students can use this platform to investigate real-world questions and generate their own arguments as a form of inquiry-based learning. Also, this places students into the role of the participant in the internet as they engage in discovering, remixing, and sharing content. As a result, mashups provide pedagogical opportunities, among them, as a tool within the constructivist approach to learning and also a way of teaching digital literacy, science, social studies, video production, and web development. Mashups rely on open and discoverable resources, open and transparent licensing, and open and remixable formats.
