Wikipedia’s “page” level Data Model (Photo credit: Wikipedia)

In a previous post I described what the W3C Widget specification is and how it works. In this post I’ll describe how to create a more useful widget than the typical “HelloWorld” that will follow the W3C Widget spec. This may seem a bit late to the party, as people were actively creating and exchanging “widgets” in the Web2.0 era from 2006-2012, but in this author’s opinion, the pendulum tends to swing back and forth fairly frequently and what once was considered “latest & greatest” and now is considered “old hat or yesterday’s news” is typically tossed aside far too quickly. With W3C Widgets, while the core technology premise of “embedding functionality from one domain into another domain” or combining/integrating functionalities of multiple domains, may not seem that exciting; it is important that we do not “throw the baby out with the bathwater” as many of the mistakes of the past are sure to be repeated.


Usefulness of Wikipedia and its data

Its no secret that one of the primary data sources on the web about this planet/universe of our’s, has quickly become Wikipedia. A simple “user-generated content” web application which started out its early Web2.0 origins enabling anyone in the world to “add knowledge about a particular topic in the form of a page” (if you haven’t seen the founding story TED Talk by Jimmy Wales, give it a watch); Wikipedia has grown immensely to become the largest known encyclopedia. Not to mention being looked at in many “academic circles” as somewhat of a joke for that same reason (massive growth, ability for anyone to add content, lack of depth or sufficient expert contributors). Citing any number of reasons, the academic world was extremely reluctant to not only embrace but even acknowledge Wikipedia as a legitimate research resource or learning tool. “An encyclopedia on the internet“, they said… “Created by and for the people“, they said… “Moderated by the under-educated (in our not so humble opinion) masses“, they said… “Not funded by a major Printing/Publishing conglomerate”, they said? Pfff… stupid, it’ll never work. Indeed, many of the top Universities in the world continue to plan for if not encourage its demise.

Yet today, ranked #5 of all websites globally by traffic/views, Wikipedia is one of the most-used informational resources of any kind in the entire world. In August there were over 2.9 million edits per day on average. Articles are moderated at an alarming pace, with outright vandalism of pages automatically detected and prevented, as well as factual errors being edited our within moments of posting. On top of the original 2005 study that pitted Wikipedia side-by-side with Encyclopedia Britannica and showed it as if not slightly more reliable, a study released just this month showed that Wikipedia is slightly more accurate than Pharmacology Textbooks. Web dominator Google itself, after acquiring SemanticWeb metadata company Freebase to seed its KnowledgeGraph algorithms on, has begun basing a major portion of its entire search result set on a curated dataset which combines Freebase and Wikipedia data sets. The former known as the “Freebase RDF linked data dump” (consisting of over 1.8 Billion triples) and the latter known as the “Wikidata export” (consisting of over ).

Suffice to say that one of the “most-requested” integration I get is, for better or worse, Wikipedia. From Universities themselves – ironically enough trying to integrate Wikipedia results – directly on their Student portals, to small businesses trying to offer extra contextual information to keep users on their websites (which are often otherwise fairly bare informational websites), to startups who are trying to extract Semantic meaning from or perform Natural Language Processing on some text data, Wikipedia is leading the pack as the center of information on the web. When combined with other Linked Data Sources, as is accomplished through DBpedia, it is indeed an extremely powerful tool for anyone from researchers to the lay person looking up basic info.

So, now that we’ve laid out and understood the usefulness of Wikipedia data (and now that I’m doing alot less consulting work), I figure its a good time to offer a little look behind the curtains into just how easy it can be to integrate Wikipedia data to your own app, service, website or tool.


Wikipedia’s API

First thing’s first, Wikipedia has indeed offered an API since its earliest days on the web (although the format has changed several times, and  quite a bit overall since 2005-2006 version of the API first launched). For the longest time, it was just sort of there, largely unknown but as soon as people started to find out about it, its usage sky-rocketed and strict API request limits per put in place (both request/second and total monthly request limitations). At least this was a better approach than the throttling/ignoring requests approach other leading open source databases whose API usage started hammering their servers initially chose to do (i.e. MusicBrainz, GeoNames etc…. both of which have since gone the “rate limit” approach to managing the usage demands).


Wikipedia Widget

The widget itself is quite simple and comprised of the following:

  • HTML Search form to input query to search Wikipdia form
  • CSS to define some basic styling/layout
  • JS handler to handle making API requests of the correct format
  • Wikitext syntax parser to format the result data
  • CORS or Proxy must be in place on the server to enable cross-domain API calls

Regular broadcast standards or special mobile TV transmission formats can be used. Additional features include [[download]]ing [[TV program]]s and [[podcast]]s from the Internet and storing programming for later viewing.nnAccording to the ''Harvard Business Review'', the growing adoption of [[smartphones]] allowed users to watch as much mobile video in three days of the [[2010 Winter Olympics]] as they watched throughout the entire [[2008 Summer Olympics]] – an increase of 564%.[ Looking for TV Genius? | Red Bee Media]  {{webarchive|url= |date=April 30, 2011 }}[ ] nnEarly mobile television receivers were based on the old [[analog television]] signal system. They were the earliest televisions that could be placed in a coat pocket. The first was the Panasonic IC TV MODEL TR-001, introduced in 1970. The second was sold to the public by [[Clive Sinclair]] in January 1977. It was called the Microvision or the [[MTV-1]]. It had a two-inch (50 mm) [[Cathode ray tube|CRT]] screen and was also the first television which could pick up signals in multiple countries. It measured 102×159×41 mm and was sold for less than [[Pounds sterling|£]]100 in the [[United Kingdom|UK]] and for around [[US dollar|$]]400 in the [[United States]]. The project took over ten years to develop and was funded by around £1.6 million in British government grants.[ Clive's achievements] [[Sinclair Research]][ Video and TV gear], [[]]nnIn later decades the term "mobile television" was associated with mobile telephones and other mobile digital devices. Mobile TV is among the features provided by many 3G phones.nnnIn 2002, South Korea became the first country in the world to have a commercial mobile TV by CDMA IS95-C network, and mobile TV over 3G ([[CDMA2000]] 1X EVDO) also became available in that same year. In 2005, South Korea became the first country in the world to have mobile TV. It started satellite DMB (S-DMB) and terrestrial DMB (T-DMB) services on May 1 and December 1. Today, [[South Korea]] and [[Japan]] are at the forefront of this developing via Yahoo!

The same service was also deployed to the Philippines in 2007. [[British Telecom|BT]] in the [[United Kingdom]] was among the first companies outside South Korea to launch mobile TV in September 2006, although the service was abandoned less than a year later.ZDnet: [,1000000085,39288247,00.htm BT ditches mobile TV service], 26 July 2007 The same happened to MFD Mobiles Fernsehen Deutschland, who launched their [[Digital Multimedia Broadcasting|DMB]]-based service June 2006 in Germany, and stopped it in April 2008.Broadband TV news: [ MFD hands back German T-DMB licence], May 1, 2008 Also in June 2006, mobile operator 3 in Italy (part of [[Hutchison Whampoa]]) launched their mobile TV service, but opposed to their counterpart in Germany this was based on [[DVB-H]].''The Register'': [ DVB-H rockets ahead in Italy], 28 July 2006 Sprint started offering the service in February 2006 and was the first US carrier to offer the service. In the US [[Verizon Wireless]] and more recently [[AT&T Mobility|AT&T]] are offering the service.nnIn South Korea, mobile TV is largely divided into satellite DMB ([[S-DMB]]) and terrestrial DMB ([[T-DMB]]). Although S-DMB initially had more content, T-DMB has gained much wider popularity because it is free and included as a feature in most mobile handsets sold in the country today.nn==Challenges==nMobile TV usage can be divided into three classes:n* "Fixed" – watched while not moving, possibly moved when not being watchedn* "Nomadic" – watched while moving slowly (e.g. walking)n* "Mobile" – watched when moving quickly (e.g. in a car)nnEach of these pose different challenges.nn===Device manufacturers' challenges===nn* Power consumption – continuous receipt, decoding, and display of video requires continuous power, and cannot benefit from all of the types of optimizations that are used to reduce power consumption for data and voice services.n* Memory – to support the large buffer requirements of mobile TV. Currently available{{when|date=August 2012}} memory capabilities are not suited for long hours of mobile TV viewing. Furthermore, potential future applications like [[peer-to-peer video sharing]] in mobile phones and consumer broadcasting would add to the increasing memory requirements{{why?|date=August 2012}}. The existing P2P algorithms are not expected to be enough for mobile devices, necessitating the advent of [[mobile P2P]] algorithms{{why?|date=August 2012}}. There is one start-up technology that claims [[patent]]ability on its mobile P2P, but has not drawn attention from device manufacturers yet.{{citation needed|date=January 2014}}nnn* Display – larger and higher-resolution displays are necessary for an optimal viewing experience.n* Processing power – significantly more processor performance is required for mobile TV than that used for UI and simple applications, like browsers and messaging.nn==Digital television==nn===North America===n{{As of|2012|01}}, there were 120 stations in the United States broadcasting using the [[ATSC-M/H]] "Mobile DTV" standard – a mobile and handheld enhancement to the HDTV standard that improves handling of [[multipath interference]] while mobile.{{cite web|title=OMVC announces sizable growth in number of MDTV stations at CES|url=|website=Broadcast Engineering|accessdate=18 August 2015|archiveurl=|archivedate=22 September 2012|date=19 January 2012}}nnnThe defunct [[MediaFLO]] used [[COFDM]] broadcast on [[UHF]] [[TV channel]] 55. Like satellite TV, it was [[encrypt]]ed and controlled by [[conditional access]] (provided via the [[cellular network]]). It required a [[Pay TV|subscription]] for each mobile device, and was limited to the [[AT&T Mobility]] or [[Verizon Wireless]] networks.nn===Broadcast mobile DTV development===nnWhile MediaFLO used the TV spectrum and [[MobiTV]] used [[Mobile phone|cell phone]] networks,{{cite news|url= |title=mobile tv cell phone networks: |last=Thompson |first=Mark |date=2010-06-03 |work=[[Broadcasting & Cable]] |accessdate=2010-06-03 |deadurl=yes |archiveurl= |archivedate=May 15, 2010 }} "mobile DTV" (ATSC-M/H) used the [[digital TV]] spectrum.nnAt the April 2007 [[National Association of Broadcasters|National Association of Broadcasters (NAB)]] in [[Las Vegas Valley|Las Vegas]], the [[ATSC]] and [[8VSB]] methods for delivering mobile DTV were shown. [[A-VSB|Advanced VSB (A-VSB)]], from [[Samsung Group|Samsung]] and [[Rohde & Schwarz]], was shown at the April 2006 show. In 2007, [[Zenith Electronics]], owned by [[LG Group|LG]], came up with 8VSB, which was introduced with [[Harris Corporation|Harris Group]]'s) [[MPH (ATSC)|Mobile-Pedestrian-Handheld (MPH)]] system.nnAs the broadcast networks began making their content available online, mobile DTV meant stations would have to find another way to compete. [[Sinclair Broadcast Group]] tested A-VSB in the fall of 2006. Their stations [[KVCW]] and [[KSNV|KVMY]] were participating in the mobile DTV [[product demonstration|products demonstrations]] at the NAB show. A-VSB had worked in [[bus]]es at the 2007 [[Consumer Electronics Show]].nn[[ION Media Networks]] started a test station on channel 38, which was to be used for digital [[LPTV]], which used a [[single-frequency network|single-frequency network (SFN)]]. In some areas, more than one [[TV transmitter]] would be needed to cover all areas. Mobile DTV could have been used at that time because it would not affect [[HDTV]] reception. A single standard, however, had to be developed.{{cite news|url=|title=NAB: Mobile DTV Hits the Strip|last=Dickson |first=Glen |date=2007-04-14 |work=[[Broadcasting & Cable]] |accessdate=2009-07-21}}nnAt the Consumer Electronics Show in January 2009, the first [[prototype]] devices from LG and other manufacturers were demonstrated, including receivers for cars from [[Kenwood Corporation|Kenwood]], [[Visteon]] and [[Delphi (auto parts)|Delphi]]. It was announced that 63 stations in 22 markets would debut the service in 2009. [[Gannett Broadcasting]] president David Lougee pointed out that many of those attending the [[First inauguration of Barack Obama|inauguration of Barack Obama]] would likely hear him but not see him; had the new technology been in place, this would not have been a problem.{{cite news|url=|title=CES: Broadcasters' Mobile DTV Moment|last=Dickson |first=Glen |date=2009-01-11 |work=[[Broadcasting & Cable]] |accessdate=2009-12-03}}nnIn April 2009, the [[Open Mobile Video Coalition]], made up of over 800 broadcast stations, selected four test stations: Gannett's [[WATL (TV)|WATL]], ION's [[WPXA-TV]] in [[Atlanta, Georgia|Atlanta]], [[Fisher Communications|Fisher Communications']] [[KOMO-TV]], and [[Belo]]'s [[KONG-TV]] in [[Seattle, Washington|Seattle]].

The [[OMVC]] persuaded LG and Samsung to work together starting in May 2008 so that differing systems (possibly a self-destructing format war) would not delay or kill the technology.nnEarly in July 2009, the ATSC Technology and Standards Group approved the [[ATSC-M/H]] standard for mobile DTV which all members green-lighted October 15. The public could be using the new devices by 2010, though watching TV on [[cell phone]]s seemed unlikely in the near future since telephone manufacturers did not yet include that capability. The technology was expected to be used for [[Opinion poll]]s and even voting.{{cite news|url= |title=ATSC-M/H voted to proposed standard status |last=Dickson |first=Glen |date=2009-07-06 |work=[[Broadcasting & Cable]] |accessdate=2009-07-08}}{{cite news|url=|title=Mobile DTV Standard Approved|last=Dickson |first=Glen |date=2009-10-16 |work=[[Broadcasting & Cable]] |accessdate=2009-10-16}} By the end of the year, the ATSC and the [[Consumer Electronics Association]] began identifying products meeting the standard with "MDTV".{{cite news|url=|title=ATSC Launches Certification Program For Mobile DTV|last=Dickson|first=Glen|date=2009-12-16|work=[[Broadcasting & Cable]]|accessdate=2009-12-17}}nnPaul Karpowicz, NAB Television Board chairman and president of Meredith Broadcast Group, said 
"This milestone ushers in the new era of digital television broadcasting, giving local TV stations and networks new opportunities to reach viewers on the go. This will introduce the power of local broadcasting to a new generation of viewers and provide all-important emergency alert, local news and other programming to consumers across the nation."
nnLater in July, the first multi-station tests began in [[Washington, D.C.]], while single stations in [[New York (city)|New York City]] and [[Raleigh, North Carolina]] already offered mobile DTV. The OMVC chose Atlanta's WATL and Seattle's KONG as "model stations" where product testing could take place. Seventy stations in 28 [[media market]]s planned streams by the end of 2009. All of the stations would have two or more channels each, with "[[electronic program guide|electronic service guide]] and alert data" among the services.nnTwenty sellers of equipment would use these stations to test using the existing standard, but testing the final standard would come later, and tests by the public would happen in 2010, when many more devices would be ready. Manufacturing large numbers of the devices could not take place without the final standard. LG, however, began mass-producing chips in June. ION technology vice president Brett Jenkins said, "We're really at a stage like the initial launch of DTV back in 1998. There are almost going to be more transmitters transmitting mobile than receive devices on the market, and that's probably what you'll see for the next six to nine months."nnDevices would eventually include [[USB]] dongles, [[netbook]]s, [[Portable DVD Player|portable DVD players]] and in-car displays.{{cite news|url= |title=Special Report: Mobile DTV Heats Up |last=Dickson |first=Glen |date=2009-07-13 |work=[[Broadcasting & Cable]] |accessdate=2009-07-15}}nnWhite House officials and members of [[United States Congress|Congress]] saw the triple-play concept in an ION demonstration on July 28, 2009 in conjunction with the OMVC.{{cite news|url=|title=ION, OMVC Organize DTV Showcase in D.C.|last=Dickson |first=Glen |date=2009-07-22 |work=[[Broadcasting & Cable]] |accessdate=2009-07-22}}{{cite news|url= |title=LIN TV Develops Blackberry App For Mobile TV Service|last=Eggerton |first=John |date=2009-08-07 |work=[[Broadcasting & Cable]] |accessdate=2009-08-11}} Another demonstration took place October 16, 2009 with journalists, industry executives and broadcasters riding around Washington, D.C. in a bus with prototype devices.

According to NPD’s “Free Streaming TV” report, released in February 2013, 12 percent of United States TV watchers reported streaming TV shows for free during the prior three months, compared to 14 percent who watched a TV show via SVOD.Free Streaming Making Inroads with Traditional Television Consumers from The [[NPD Group]]:"Over half of the viewers for streaming TV are between the ages of 18 and 34, so the YouTube generation is evolving from short-form and user-generated content to TV shows and, like YouTube, they can watch where and when they want," said Russ Crupnick, senior vice president of industry analysis at NPD. "Despite the attention lavished on tablets and phones, an astonishing 83 percent of free TV streaming programs are viewed on a computer."nn==Market structure==nn'''Estimated worldwide numbers of mobile TV subscribers'''n{| class="wikitable sortable" border="1"n|-n!Year!!Subscribers!!Sourcen|-n| align="left" | Q4 2005n| align="left" | 6,400,000n| align="left" | ABI Research[]n|-n| align="left" | Q4 2006n| align="left" | 11,000,000n| align="left" | ABI Research[]>n|-n| align="left" | Q4 2007n| align="left" | 29,700,000n| align="left" | In-Stat[]n|-n| align="left" | Q4 2008n| align="left" | 75,000,000n| align="left" | Visiongain[]n|-n| align="left" | Q4 2009n|-n| align="left" | Q4 2010n| align="left" | 179,500,000n| align="left" | RNCOSn|-n| align="left" | Q4 2011n| align="left" | 271,000,000n| align="left" | RNCOSn|-n| align="left" | Q4 2014n| align="left" | 792,500,000n| align="left" | RNCOS[ Global Mobile TV Forecast to 2013]n|}nn==Standards==n;Telecomn*[[eMBMS]] Mobile Broadcast Multicast Service (e for evolved i.e. on LTE)n;Terrestrialn*[[1seg]] (One Segment) – Mobile TV system on [[ISDB-T]]n*[[ATSC-M/H]] (ATSC Mobile/Handheld) – North American*[[Digital Audio Broadcasting|DAB-IP]] (Digital Audio Broadcast) – UKn*[[Digital Multimedia Broadcasting|T-DMB]] (Terrestrial Digital Multimedia Broadcast) – South Korean*[[DMB-T/H]] – China n*[[DVB-H]] (Digital Video Broadcasting – Handheld) – [[European Union]], Asian**[[DVB-T]] (Digital Video Broadcasting – Terrestrial)n**[[DVB-T2]]n**[[DVB-T2 Lite]] – Europe, Africa, Asia and some countries in South American**[[DVB-H#DVB-NGH|DVB-NGH]]n*[[Integrated Mobile Broadcast|iMB]] (Integrated Mobile Broadcast, 3GPP MBMS)n*[[ISDB#ISDB-Tmm|ISDB-Tmm]] (Integrated Services Digital Broadcasting – Terrestrial Mobile Multimedia) – Japann*[[MediaFLO]] – launched in US, tested in UK and Germanyn;Satelliten*[[CMMB]] (China Mobile Multimedia Broadcasting) – Chinan*[[DVB-SH]] (Digital Video Broadcasting – Satellite for Handhelds) – European Unionn*[[S-DMB]] (Satellite Digital Multimedia Broadcast) – South Koreann== See also ==n*[[Handheld projector]]n*[[Multimedia Broadcast Multicast Service]] (MBMS) via the [[GSM]] and [[UMTS]] cellular networksn*[[IPTV]]n*[[iPAD TV]] Film Festival TV on iTUNESn*[[SPB TV]]n*[[Webkuti Live TV]]n*[[Mobile DTV Alliance]] – marketing organizationn*[[3 mobile tv (UK)]]n*[[Mobiclip]]n*[[MobiTV]]n*[[Nunet]]n*[[Mobibase]]n*[[Handheld television]]n*[[World Entertainment Box]]n*Vintage Micro Television References ==n{{Reflist|30em}}n* {{cite web|last=Reardon|first=Marguerite|title=Local TV Could Spur Mobile TV Adoption|url=|publisher=CNET|accessdate=2012-08-09|date=2010-01-07}}n* {{cite web|title=EU backs standard for mobile TV|url=|publisher=BBC News|accessdate=2012-08-09|date=2007-07-18}}nn== External links ==n* [ Mobile TV solutions for eMBMS, LTE, ATSC-MH and ISDB-T]n* [ EU back mobile TV standard]n* [ Economics] Digital TV Development: Techno-Economic Analyses and Generic Modelling, covering also Mobile TV; Growth factors.n* [ Mobiletvworld]n* [ Mobile TV Elite - Watch Live TV On Your Mobile Device]n* [ Mobile TV Software]n* [ Mobile TV for iPads & iPhones]n* [] Listings of currently available or future Mobile DTV signals, by city/regionn* [] Listings of currently available or future Mobile DTV signals, by city/regionn*[ Mobile DTV, Analysis, Monitoring, Measurement]n*[ Mobile DTV Viewer]n*[ Cross Platform Live TV service for Indian Audience]n*Mobdro tv app You can use this app for Mobile Television n{{Wireless video}}n{{Telecommunications}}n{{Mobile phones}}nn{{DEFAULTSORT:Mobile Tv}}n[[Category:Broadcast engineering]]n[[Category:Digital television]]n[[Category:Mobile telephone broadcasting]]n[[Category:Mobile television| ]]n[[Category:Television technology]]n[[Category:Telecommunications-related introductions in 1970]]nn[[es:DVB sobre IP]]n[[tr:Mobil TV]]n[[zh:手機電視]]" } ] } ] } }

Another cool thing is that if you have a your own (i.e. local for dev purposes or some company/intranet-specific) installation of WikiMedia, the open source software that runs Wikipedia itself and is provided by the foundation free of charge, you can also query your own pages/articles via the same API that is provided by default OOTB. Here’s an example:

The following is the finished “Wikipedia Widget” which follows the W3C Widget:




  1. “Wikipedia: The Missing Manual: The Missing Manual” by John Broughton: (sections on Edit Wars, )
  2. “Wikipedia as accurate as Encyclopedia Britannica” by Daniel Terdiman:
  3. “This machine kills trolls – How Wikipedia’s robots and cyborgs snuff out vandalism” by Jesse Hicks:
  4. Wikimedia Stats on edits, page creation, etc:

BC$ = Behavior, Content, Money

The goal of the BC$ project is to raise awareness and make changes with respect to the three pillars of information freedom - Behavior (pursuit of interests and passions), Content (sharing/exchanging ideas in various formats), Money (fairness and accessibility) - bringing to light the fact that:

1. We regularly hand over our browser histories, search histories and daily online activities to companies that want our money, or, to benefit from our use of their services with lucrative ad deals or sales of personal information.

2. We create and/or consume interesting content on their services, but we aren't adequately rewarded for our creative efforts or loyalty.

3. We pay money to be connected online (and possibly also over mobile), yet we lose both time and money by allowing companies to market to us with unsolicited advertisements, irrelevant product offers and unfairly structured service pricing plans.
