City wiki

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A city wiki (or local wiki) is a wiki used as a knowledge base and social network for a specific geographical locale. The term 'city wiki' or its foreign language equivalent (e.g. German 'Stadtwiki') is sometimes also used for wikis that cover not just a city, but a small town or an entire region. A city wiki contains information about specific instances of things, ideas, people and places. Much of this information might not be appropriate for encyclopedias such as Wikipedia (e.g., articles on every retail outlet in a town), but might be appropriate for a wiki with more localized content and viewers. A city wiki could also contain information about the following subjects, that may or may not be appropriate for a general knowledge wiki, such as:

  • Details of public establishments such as public houses, bars, accommodation or social centers.
  • Owner name, opening hours and statistics for a specific shop.
  • Statistical information about a specific road in a city.
  • Flavors of ice cream served at a local ice cream parlor.
  • A biography of a local mayor and other persons

The Open Guide to London is probably the oldest of the city wikis.[1] It is part of a sub group of city wikis that use the OpenGuides software, and most have the domain in their URL. Most of them are for cities in England. Although Cityultima, formerly Cityunlimited was founded in February 2007. The Stadtwiki Karlsruhe is the largest city wiki.

Growth of article count on the Karlsruhe Stadtwiki

The table below, adapted from a more detailed table on the Omaha Wiki, provides information on the 30 largest city wikis worldwide, ranked by the number of articles as of August 31, 2010. Twenty-six of the city wikis use the MediaWiki software, three use the Sycamore software (Davis, Rochester, Santa Cruz), and one uses the OpenGuides software (London). Some of the methods for reporting metrics vary between the different types of wikis and thus care should be used when comparing across them. For example, the Sycamore stats do not break out counts for pages outside the main article namespace (e.g. user, project, image, template, help, category namespaces in MediaWiki) so the article counts between the MediaWiki and Sycamore wikis cannot be directly compared. For the MediaWiki sites, over half of the pages are in these supporting namespaces and are not included in the counts below. The user counts for most Sycamore wikis show only users with at least one edit while the user counts for the MediaWiki sites include users who have not made any edits. Given these differences, the numbers below tend to overstate article counts for Sycamore wikis and understate the number of users.

The columns below can be sorted by clicking on the symbol below the column heading. The "Total" columns show all activity since the wiki was founded.[2] These metrics will be updated at the end of each month.[3]

  2. ^ The dates of founding were based on (a) the first edit done on the Main Page (Hauptseite) for MediaWiki wikis or (b) the first edit for Sycamore wikis. If the city wiki uses the MediaWiki software, the article page count is accessible by requesting the Special:Statistics?action=raw page. If the Sycamore wiki engine is used, the /User Statistics page is accessed, all text is selected and copied into an Excel file, and totals are calculated for number of articles, number of edits, and number of files. The Sycamore statistics do not include new article creation as an 'edit' (MediaWiki does), the numbers reported above as 'edits' for the sites using Sycamore is the sum of new articles created plus and edits to these articles in order to provide comparable numbers.
  3. ^ If anyone is aware of a city wiki with more articles than 1,000 articles (legitimate content pages), post a comment on the discussion page with the name and URL of the City Wiki and its statistics will be checked on the next monthly update.
