The German Wikipedia (German: Deutschsprachige Wikipedia) is the German-language edition of Wikipedia, a free and publicly editable online encyclopedia. It is the second largest Wikipedia, after the English Wikipedia, and was one of the first to be created.

Contents

[edit] History

The first non-English Wikipedia subdomain was the German one; it was announced by Jimmy Wales on 16 March 2001.[1] Creation of articles in the German Wikipedia started in May 2001,[2] later than in the Catalan Wikipedia.

[edit] Size, coverage and popularity

Article growth, 2001 - June 2007

As of May 2008, this edition had more than 750,000 articles[3], ranking second in size behind the English language edition. 98%[4] of the articles had more than 200 characters, 89%[4] had more than 512 bytes, 44%[4] had more than 2 KB, the average article size was 3153[4] bytes or 430[4] words. This edition had nearly 125,000 biographies and more than 48,500 disambiguations.[5]

Compared to the English Wikipedia, the German one tends to be more selective in its coverage[citation needed], often rejecting small stubs, articles about fictional characters and similar materials. This is not always the case however; though all characters from Star Wars have been condensed into one article, characters such as Abu el-Hasan from the Thousand and One Nights and Wolverine have their own pages. Yet despite its rejection of articles on fictional subjects, the German Wikipedia is keeping at least one fictitious entry: it has had an entry on the nonexistent insect "Leuchtschnabelbeutelschabe" since January 2003, which was kept after deletion discussions in January 2005 [6] and June 2006 [7][8]; more recent requests for deletion are no longer even discussed[9]. However, this article is an exception as it is considered (according to the deletion request discussions) to be comparable to the fictitious entry Stone louse in a German medical encyclopedic dictionary as the German Wikipedia's "classic" mascot joke entry. The German Wikipedia doesn't usually tolerate fictitious entries.

One aspect where the German Wikipedia has a larger and more complete coverage than the English Wikipedia is towns and villages in the Czech and Slovak Republics, Poland[citation needed] and other Central and eastern European countries. This is largely because of the large German minorities (or sometimes even majorities) that used to live in these countries before the end of the Second World War.

The January 2005, Google Zeitgeist announced that "Wikipedia" was the #8 most searched query on Google.de, ranking only behind the tsunami, George Bush, firefox, Schnappi, Rudolph Moshammer, Saturn, and Angelina Jolie. In February 2005 Wikipedia reached third place behind Firefox and Valentine's Day. In June 2005, Wikipedia ranked first.

[edit] Language and dialects

Number of members
Number of members

The German Wikipedia is written in the German language as recommended by the Duden. Swiss or Austrian idiosyncrasies are accepted only in articles of regional scope. The differences are smaller than those between American English and British English; for instance, the Swiss don't use the sharp S (ß) and write ss instead.

German dialects like Swiss German are not used in the German Wikipedia. Separate Wikipedias have been created for several German dialects, including Alemannic German (als:), Low German (nds:), (lb:), Pennsylvania German (pdc:), Ripuarian (formerly Kölsch; ksh:), and Bavarian (bar:).

[edit] Characteristics

Daily requests for deletion, de facto deleted articles and the ratio of these two values
Daily requests for deletion, de facto deleted articles and the ratio of these two values

The German Wikipedia is different from the English Wikipedia in a number of aspects.

  • There are stricter rules of encyclopedic notability for deciding if an article about a topic should be allowed. For example, rules about (especially contemporary) fictional creatures are extremely strict. E.g. individual articles about characters in Star Trek, Star Wars, Harry Potter, Lord of the Rings etc. are largely deemed undesirable and are in most cases deleted or alternatively merged into a single article; for example, where there are articles like Gandalf and Frodo Baggins in the English Wikipedia, the German Wikipedia tolerates only a single article describing the characters in Tolkien's fictional world: Figuren in Tolkiens Welt. Articles dealing with future events or publications (e.g. computer games) are also more likely to be deleted wholly as "crystal balling". For example, as of mid-2007, there was no article about the upcoming German computer game Crysis, as opposed to the other large Wikipedia languages; the article was deleted and blocked after several discussions, restored and unblocked only a month before the game's announced release date.
  • There are no fair use provisions. Images and other media that are accepted on the English Wikipedia as fair use may not be suitable for the German Wikipedia.
  • The use of scholarly sources, in preference over journalistic and other types of sources, is more strongly encouraged. The German WP:BLG guideline classifies scholarly sources as inherently more reliable than non-academic sources; the latter's use is – in theory at least – only permitted if there is a lack of published academic sources covering a topic.
  • Many controversial articles are protected for months and cannot be edited by unsubscribed or recently subscribed users.[10] On September 14, 2005, 253 pages were protected (compared to 138 in the English Wikipedia). This was the highest number of blocks of all wikipedias.[11]
  • Articles on indisputably notable subjects may be deleted if they are deemed too short. While the requirements for minimal articles (called stubs) are equivalent, the German and the English Wikipedia differ greatly when putting them into practice.[12]
  • On December 28, 2005 it was decided to eliminate the Category "stub" (and the corresponding template identifying articles as stubs) from the German Wikipedia.[13]
  • Unlike the French, Polish or Italian Wikipedias, the German Wikipedia does not contain large collections of bot-generated stubs.
  • Unlike the French and English Wikipedias, the German long did not have an Arbitration Committee; the first elections for an Arbitration Committee were held in May 2007.
  • Categories are singular and are not differentiated for gender. Categories are usually introduced only for a minimum of ten entries and are not always subdivided even for larger numbers of items, so that current categories often describe only one property (e.g., nationality). Other categories are subdivided, but differently than in the English Wikipedia. For example, "chemists" are subdivided by century, not by nationality. A university professor, on the other hand, will usually be categorized for where he or she teaches.
  • The equivalent to the English Wikipedia's featured articles and good articles are exzellente Artikel (excellent articles) and lesenswerte Artikel (good articles; etymologically: articles "worth reading").
  • In 2005, there was a discussion and poll resulting in the decision to phase out the use of local image uploads and to exclusively use Wikimedia Commons for images and other media in the future. [14] The attempt to implement this lasted for about a year and the German "Upload file" page displayed a large pointer to Commons in this time, but since December 2006, there is again a local image upload page without any pointer to Wikimedia Commons. This was prompted by the deletion of images on Commons that are acceptable according to German Wikipedia policies. [15]
  • Persondata, as introduced in the English Wikipedia in December 2005, was pioneered by the German Wikipedia in December 2004.
  • Like the Signpost in the English Wikipedia, the German Wikipedia also has its own internal newspaper, the Kurier. However, the Kurier is laid out on a single page and is not issued weekly but is continuously updated by interested Wikipedians, with older articles being archived.
  • Auftragsarbeiten is a page where users can offer various rewards for completion of Wikipedia-related tasks. Started in July 2005, the idea initially met with some resistance, similar to the recently proposed Reward board in the English Wikipedia.

[edit] Reviewed versions

At Wikimania 2006, Jimbo Wales announced that the German Wikipedia would soon institute a system of "stable article versions" on a trial basis. The system went live in May 2008. Certain users are now able to mark article versions as "reviewed", indicating that the text contains no obvious vandalism. A note in the top right corner of the screen indicates to the reader whether or not the present version of an article has already been reviewed, and provides access to the most recent reviewed version or a more current, unreviewed version as needed.

[edit] Community organisation

Since July 2004 some German Wikipedians have employed a web of trust known as Vertrauensnetz: they use a special template on a subpage of their user page to list all the other users whom they trust, along with reasons for the trust and links to the other users' trust pages. This "trust" is not meant as personal sympathy, but as testimony of serious engagement with the Wikipedia project. By using the "What links here" feature, one can then also obtain a list of all participants who trust a given user.

In February 2006 a new experimental project was started with the goal of evaluating users, providing feedback, and eventually eliminating the voting for adminships. Every participating user keeps a special evaluation subpage of their user page; others can leave positive or negative evaluations (with reasons) of the user on that page. A central page keeps track of the net number of positive evaluations received by every participant.

[edit] Events

The first real-life meetup of Wikipedians took place in October 2003 in Munich.

Each spring and autumn the German Wikipedia organizes a writing contest where a community elected jury rates nominated articles. Prizes are sponsored by individual community members and companies. The first contest was held in October 2004, among the 44 nominations the article Kloster Lehnin won. The second contest in March saw 52 contributions, the third in September 2005 already 70. A trial to extend the contest to an international level met with limited success, only the Dutch, English and Japanese Wikipedias participated in the end[16] For the writing contest in March 2006 the 150 nominations were split in three sections, history & society (56 nominations), arts & humanities (36) and science (46). The article on the Braunbär (Brown Bear) won, 27 articles reached featured status a few weeks after the contest.[17] In March 2007 there was the 6th edition with the winning article Haager Konvention zum Schutz von Kulturgut bei bewaffneten Konflikten (Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict).

German Wikipedians organized the first international Wikipedia conference, Wikimania 2005, in August 2005 in Frankfurt. Some 300 people from over 50 countries attended the three-day conference.

From 17 March to 15 April 2006, the Göttingen State and University Library held a special exhibition documenting the first 5 years of Wikipedia.[18]

In 2006 at the University of Göttingen the first Wikipedia Academy was held. The Academy is intended to familiarize the academic world with Wikimedia projects. In 2007 the second meeting took place. This year the event was organized in conjunction with the Akademie der Wissenschaften und der Literatur (Academy of Science and Literature) in Mainz and was a part of the German Jahr der Geisteswissenschaften (Year of the Humanities), organized by the German Federal Ministry for Education and Research. The event had a remarkable impact on German scholars' view of Wikipedia and its sister projects in general.[citation needed] A third meeting is scheduled for 20-21 June 2008 in Berlin[19].

[edit] Contacts with Brockhaus

In April 2004, a complete list of article titles from the leading German encyclopedia Brockhaus was uploaded to the German Wikipedia, in an apparent attempt to facilitate the creation of still missing articles. A representative of Brockhaus asked for and obtained the deletion of what was believed to be a copyright infringement. As a result of the developing email conversation, a group of five Wikipedians visited the "new media" group of Brockhaus in Mannheim on 01 July 2004.[20] The friendly meeting saw a lively discussion of the differing approaches to writing an encyclopedia; it became clear that Brockhaus had closely observed Wikipedia for quite some time.

[edit] Article-free Sunday

On 23 November 2006, the number of articles at German Wikipedia reached 500,000. As a response to this and to the perception that quality control was not keeping up with article creation, it was proposed to declare 10 December 2006 "Article-free Sunday", a day where participants voluntarily agree to post no new articles, but instead focus on improving existing ones. It was also proposed to declare 10 December "Counter-action Article-free Sunday", a day where participants create missing articles and improve existing ones.

[edit] Subsidies from the German government

In June 2007 a project on renewable resources (WikiProjekt Nachwachsende Rohstoffe) has started.[21] [22] The goal is to write and improve articles on the topic. The project runs for three years and is subsidized by the German Ministery of Agriculture with approximately €80,000 a year. It is organised and managed by the private company "nova-Institut GmbH". Nova GmbH and Wikimedia Deutschland e.V. fund the project with approximately €60,000 a year in addition, so the budget is approximately €420,000 in total.

These funds are mainly used to organise the project and also to search for experts in the field who have not contributed to Wikipedia yet. Nova may also pay expense allowances to authors.[citation needed]

[edit] Reviews and research

In September 2004, the respected computer magazine c't compared the German Wikipedia with the Brockhaus Multimedia encyclopedia and the German edition of Microsoft's Encarta. On a scale from 0 to 5, Wikipedia 'won' with a total score of 3.4.[23]

A few weeks later, the weekly newspaper Die Zeit also compared content from Wikipedia with other reference works and found that Wikipedia only has to "share its lead position in the field of natural science."

The DVD version of Spring 2005 received a rather negative review by Björn Hoffmann — product manager working for the Bibliographisches Institut & F.A. Brockhaus in July 2005.

In November 2005 the openusability project in cooperation with the Berlin based Relevantive AG conducted a usability test of the German Wikipedia.[24] The study focused on finding information and included a set of recommendations to change the MediaWiki interface. In February 2006 the open usability project led a second test which focused on the experience of new editors.[25] The reports were published in English.

A second test by c't in February 2007 used 150 search terms, of which 56 were closely evaluated, to compare four digital encyclopedias: Bertelsmann Enzyklopädie 2007, Brockhaus Multimedial premium 2007, Encarta 2007 Enzyklopädie and Wikipedia. With respect to concerns about the reliability of Wikipedia, it concluded: "We did not find more errors in the texts of the free encyclopedia than in those of its commercial competitors".[26]

In December 2007, German magazine Stern published the results of a comparison between the German Wikipedia and the online version of the 15-volume edition of Brockhaus Enzyklopädie. The test was commissioned to a research institute (Cologne-based WIND GmbH), whose analysts assessed 50 articles from each encyclopedia (covering politics, business, sports, science, culture, entertainment, geography, medicine, history and religion) on four criteria (accuracy, completeness, timeliness and clarity), and judged Wikipedia articles to be more accurate on the average (1.6 on a scale from 1 to 6, versus 2.3 for Brockhaus with lower = better). Wikipedia's coverage was also found to be more complete and up to date, however Brockhaus was judged to be more clearly written, while several Wikipedia articles were criticized as being too complicated for non-experts, and many as too lengthy. [27][28] [29]

[edit] Off-line publication

[edit] CD November 2004

In November 2004, Directmedia Publishing GmbH started distributing a CD-ROM containing a German Wikipedia snapshot. Some 40,000 CDs were sent to registered customers of directmedia. The price was 3 euros per CD.

The display and search software used for the project, Digibib, had been developed by Directmedia Publishing for earlier publications; it ran on Windows and Mac OS X (and now also on Linux). The Wikipedia articles had to be converted to the XML format used by Digibib.

To produce the CD, a dump of the live Wikipedia had been copied to a separate server, where a team of 70 Wikipedians vetted the material, deleting nonsense articles and obvious copyright violations. Questionable articles were added to a special list, to be reviewed later. The final CD contained 132,000 articles and 1,200 images.

The ISO image was distributed for free via eMule and BitTorrent. In December, the CHIP computer magazine placed the Wikipedia data on the DVD that it distributes with every issue. The Wikipedia materials are published under GFDL while the Digibib software may only be copied for non-commercial use, except the Linux version which is GPLed.

[edit] CD/DVD April 2005

A new release of Wikipedia content was published by Directmedia on 6 April 2005. This package consisted of a 2.7 GB DVD and a separate bootable CDROM (running a version of Linux with Firefox). The CDROM did not contain all the data, but was included to accommodate users without DVD-drives. The DVD used Directmedia's Digibib software and article format; everything could be installed to a hard drive. In addition, the DVD contained an HTML tree, as well as Wikipedia articles formatted for use with PDAs (specifically, the Mobipocket and TomeRaider formats).

German Wikipedians have developed a special format for meta data about persons (name, birth date and place etc.) known as Personendaten. The main aim of this system was to aid the search features of the DVD. Personendaten were added to some 35,000 biographical articles on the live Wikipedia, partly aided by a somewhat automatic tool.[30]

The vetting process was similar to the one for the CD described above and took place on a separate MediaWiki server. The process took about a week and involved 33 Wikipedians, communicating on IRC. To prevent duplication of work, editors would protect every article that they had reviewed; links to protected articles were shown in green. Lists of potential spammed or vandalized articles had been produced ahead of time with SQL queries. Unacceptable articles were simply deleted on the spot. While the XML articles for the earlier CD version had been produced from HTML, this time a script was used to convert Wiki markup directly to the Digibib format. The final DVD contained about 205,000 articles, with every article linking to a list of contributors.

Directmedia sold 30,000 DVDs, at €9.90 each. This price included 16% taxes and a one-euro donation to Wikimedia Deutschland; production costs were about €2. The DVD image can also be downloaded for free.

Following the successful launch of the DVD, Directmedia donated high-resolution pictures of 10,000 public domain paintings to Wikimedia Commons (see related Signpost story).

The next edition of Wikipedia content was issued in December 2005 by the publisher Zenodot Verlagsgesellschaft mbH, a sister company of Directmedia. A 139 page book explaining Wikipedia, its history and policies was accompanied by a 7.5 GB DVD containing 300,000 articles and 100,000 images. The book with DVD is sold for €9.90; both are also available for free download.[31]

The vetting process for this version was different and did not involve human intervention. A "white list" of trusted Wikipedians was assembled, the last 10 days of every article's history were examined, and the last version edited by a white-listed Wikipedian was chosen for the DVD. If no such version existed, the last version older than 10 days was used. Articles nominated for cleanup or deletion were not used.

The December 2006/2007 and 2007/2008 edition can be downloaded from dvd.wikimedia.org.

[edit] Zeno.org

Main article: Zeno.org

Zeno.org is a digital library with German texts and other content such as pictures, facsimile, etc., started by the Zenodo. The content is based on the digital libraries from the CDs and DVDs published by Directmedia, The Yorck Projekt and Zenodot. It includes a stable mirror of the German Wikipedia, purchaseable as German language Wikipedia DVD-ROM.

[edit] Books

[edit] Wikipress series

The December 2005 book about Wikipedia was the first in a series titled Wikipress. These books, published by Zenodot, consisted of a collection of Wikipedia articles about a common topic, selected and edited by so-called "Wikipeditors" who may receive compensation from Directmedia. The books were assembled on a separate server from those used for the regular German Wikipedia pages. Every Wikipress book was accompanied by an "edit card", a post card that readers could send in to edit the book's contents.Wikipress books about the Nobel Peace Prize, bicycles, Antarctica, the solar system, and Hip Hop, amongst others, were released, and other books on topics as diverse as Whales, Conspiracy theories, Manga, Astrophysics, and the Red Cross were in the works. [32] Due to lack of interest, the project was ended after a few books.[citation needed]

[edit] 100 volume Wikipedia

The publisher Zenodot announced in January 2006 that they intend to publish the complete German Wikipedia in print, 100 volumes with 800 pages each, starting with the letter A in October 2006, followed by two volumes each month thereafter, to end with Z in 2010. The project, code named WP 1.0, was to be supported by 25 editors employed by Zenodot as well as a scientific advisory board. Changes made to articles before publication would also be available for incorporation into the online Wikipedia.

In March 2006, Zenodot organized a "community day" to meet with Wikipedians and discuss the project. Groups of Wikipedians had already begun to polish articles with titles Aa-Af in selected topics. In late March it was announced that the project was put on hold and no books would be published in 2006; the reason given was that community support was lacking.[33]

[edit] Bertelsmann

On April 23, 2008, the publisher Bertelsmann announced that it planned to publish a one-volume encyclopedia in September using content from the German-language Wikipedia. The volume is planned to include abbreviated entries for the 50,000 most commonly used search terms of the prior two years. The book is to be priced at 19.95 euros, with one euro from every sale going to the German chapter of the Wikimedia Foundation [34]

[edit] Legal issues and controversies

[edit] Unauthorized uses

In March 2005, the German news magazine Der Spiegel published an article on the Rwandan Genocide in its online edition; it was a copy of Wikipedia's article. The article was taken down soon after and replaced with an apology.[35]

In April 2005, the encyclopedia Brockhaus published an article about the new pope Josef Ratzinger in its online edition. Because of its close similarity to Wikipedia's article, suspicion arose right away that the Brockhaus article might have been plagiarism. The article was removed soon after but Brockhaus did not apologize or admit guilt (see the Wikipedia Signpost's coverage.)

[edit] Large-scale copyright infringement (2003-2005)

In mid-November 2005, it was discovered that an anonymous user had entered hundreds of articles from older encyclopedias that had been published in the 1970s and 1980s in East Germany. The articles were mainly on topics in philosophy and related areas. The user had started in December 2003.

A press release was issued and numerous editors started to remove the copyright protected materials. This was made difficult by the fact that the old encyclopedias were not online and not easily available from many West German libraries, and that the user had used numerous different IP addresses. The Directmedia DVD had to be updated.[36]

[edit] Bertrand Meyer article hoax

On December 28, 2005, the article on well-known computer scientist Bertrand Meyer (creator of the Eiffel programming language) was edited by an anonymous user, falsely reporting that Meyer had died four days earlier. The hoax was reported five days later by the Heise News Ticker and the article was immediately corrected. Many major news media in Germany and Switzerland picked up on the story, creating the German Wikipedia's (admittedly negligible) version of the Seigenthaler incident. Meyer himself went on to publish a positive evaluation of Wikipedia, concluding "The system succumbed to one of its potential flaws, and quickly healed itself. This doesn't affect the big picture. Just like those about me, rumors about Wikipedia's downfall have been grossly exaggerated."[37]

[edit] Naming Tron

In 2006, Wikimedia Deutschland was drawn into a legal dispute between the parents of the deceased German computer hacker Tron and Wikimedia. The parents do not wish the hacker's real name to be publicly mentioned, and in December 2005 they had obtained a preliminary injunction in a Berlin court against the American Wikimedia Foundation, requiring removal of the hacker's name from Wikipedia. The name was not removed. On January 19, 2006 they obtained a second injunction, this time against Wikimedia Deutschland, prohibiting the address www.wikipedia.de (which is under control of Wikimedia Deutschland) to redirect to the German Wikipedia at de.wikipedia.org (which is controlled by the American Wikimedia Foundation and hosts the actual encyclopedia) as long as Wikipedia mentions the hacker's name. Wikimedia Deutschland complied and replaced the redirect with a note explaining the situation, but without mentioning the Tron case specifically. The German Wikipedia remained accessible through de.wikipedia.org during this time. One day later, Wikimedia Deutschland achieved a suspension of the injunction, and linked from the note at www.wikipedia.de to the German Wikipedia. On February 9, the court invalidated the injunction, ruling that neither the rights of the deceased nor the rights of the parents were affected by publishing the name; this ruling was upheld on appeal, decided May 12.

[edit] Parodies and forks

Parodies of the German Wikipedia include Kamelopedia, born in April 2004, Stupidedia, born in December 2004, and the German version of Uncyclopedia, created in August 2005. [38]

One longtime contributor to the German Wikipedia, frustrated with what he saw as the lack of quality and the inclusion of un-encyclopedic material, produced a fork known as Wikiweise in April 2005. It is ad-supported, uses its own software (but a similar wiki markup), admits only registered editors, and prominently displays the real names of every article's major contributors.
