Editing MediaWiki/extensions

Extensions provide numerous ways to extend the core functionality of [[MediaWiki]] in ways that are more likely not to break on MediaWiki upgrades. Some types of extensions store their code inside the wiki which should be utterly avoided as then the MediaWiki team cannot assure to not break on upgrades. No guarantees are given but given a clean implementation of task X we've no need to reinvent the wheel.

It would seem that '''adding extensions is not the problematic part but removing them''' in a clean manner after they've been added at some point previously.

'''Key extensions'''
*[[#MediaWiki Language Extension Bundle]] takes care of our multilinguality.
*[[#Wikibase]] and [[#Wikibase Client]] are being developed as a part of the [[Wikidata]] project will be our structured data storage, retrieval and modification extension duo. It remains to be seen how [[#LinkedWiki]] extensions with similar functionality by the [[DBpedia]] people will develop from now on. Going to keep a close eyeon it

''' See also: '''
* [[Templates]] - they enable [[w:Transclusion|transcluding]] content. build whole page with transcluding many templates into it
* [[Categories]] - two-way hyperlinks. placing a link to a category includes an article in the [[w:set]] of articles in the category X
* [[MediaWiki/Widgets]]

= Headlined of the planned=

== Basic stuff ==
Obviously we want to have [[#EVAL]], [[#Call]], [[#Math]], [[#Loops]], [[#HashTables]] and [[#Arrays]] for starters. 

== Automation ==
[[#LinkedWiki]] so we can fetch from [[Wikipedia]] based datasets ( courtesy of [[DBpedia]] ) from category and infobox data things by using [[w:SPARQL]]. [[Wikidata]] also provides structured data that can be edited in wiki by humans or by machines via [[w:API]]. 

Consumium will use both [[DBpedia]] and [[Wikidata]] to source information onto it's own [[mw:Extensions:Wikibase|Extensions:Wikibase]] installation.

#) [[Type of business entity]]
#) Traded as stock X in stock exchange Y
#) Industry/ies
#) Founded in
#) HQ location
#) Area served / operates in
#) Products
#) Revenue
#) Operating income
#) Net income
#) Total Assets
#) Total equity
#) Number of employees
#) Subsidiaries
#) Corporate web site

See [[DBpedia]] for more of the datasets they are making available with possibility to run SPARQL queries on the endpoint they provide as a courtesy to the user.

== I18N and localization ==

=== MediaWiki Language Extension Bundle ===
All languages will be served from single wiki utilizing [[mw:MediaWiki Language Extension Bundle]]. It contains the following extensions
#)[[Universal Language Selector]] - For selecting UI and content language
#)[[#Translate|Translate extension]] - For multilang support in single wiki
#)[[#LocalisationUpdate|Localisation Update extension]]
#)[[#CleanChanges|Clean Changes extension]] for a Recent Changes view without multilinguality induced clutter
#)[[#Babel|Babel extension]] - List languages and find other speakers of your languages onwiki
#)[[#Common Locale Data Repository|cldr extension]] - Common [[w:Locale]] Data Repository, 

=== Possibly out of date ===
<s>[[#LanguageSelector]] will enable people to have the MediaWiki interface localized based on accept langs the browser sends and</s> [[#LandingCheck]] enables to make and serve pages based on what locale ( lang + country ) is given. [[#Common Locale Data Repository]] mw:Extension:CLDR - The CLDR extension contains local language names for different languages, countries, and currencies extracted from [[w:Common Locale Data Repository]] data is obviously useful for the i18n effort.

== Single sign-on ==
Will be implemented with [[#CentralAuth]] so that http://consumium.org/wiki/ and http://consuploads.consumium.org will share a single-login database over the two wikis.

== Data storage and use ==

=== Latest ===
Data will be stored in a [[w:Triplestore]] as [[w:RDF]] subject/predicate/object triplets which will be synced with from both [[Wikidata]] and [[DBpedia]]. Own Wikidata instance will be at wikidata.consumium.org and queried with [[w:SPARQL]] and used to fill in the facts for each and all languages.

=== Out of date ===
:<s>[[#KeyValue]] is an extension that allows you to store one or more key/values as Category/Key/Value triplets on a mediawiki page by using the keyvalue function. The data is stored in textform and is not typed. This extension will likely form the back bone of setting data only once and then using it to create articles for all desired locales. </s>

== Reviews ==
[[#ArticleFeedback]] enables stars of maximum stars type of polling with possibility for multiple polls for different aspects. Will be used for [[reviews]] and could potentially be h4xed to handle the [[voting]] with it's possibility to vote zeroes. [[#Reviews|Reviews extension]] also is potential code that could be used for the reviews.

== Feedback ==

[[#ArticleFeedbackv5]] is a textbox feedback system and most likely used as a front-end to the consumer when s/he sends [[feedback]]

== Ads and anti-ads ==
[[#Widgets]] and especially the http://www.mediawikiwidgets.org/YouTube widget is a clear, reliable, safe way to have the [[advertisement video]]s and [[anti-ads]]

== Linking to other sites/wikis ==
[[#BADI Pages Created Links]] - ability to color outgoing links based on "article exists in target wiki/site / article does not exist. For example this will be used to link to the relevant [[Wikitravel]] and [[Transnationale]] articles.

== Housekeeping ==
Obviously [[#BrokenLinks]] for housekeeping.

== Editor convenience == 
[[#NewArticleTemplates]] enables to insert article skeletons into edit boxes when creating article and [[#HideEmptySections]] hides all sections that are empty when viewing an article. This way we can have large article skeleton for the convenience of the editors but avoid articles seeming like skeletons as empty headers will not display.

[[#Cite]] - obviously going to need citations for any controversial claims.

[[#HeadersFooters]] - ability to have headers and footers to be included on a global, namespace, category or page basis. Useful for placing copyright and other notes where-ever neede

[[#CSS MenuSidebar]] - navigation to special and other pages via additional menus to the sidebar

[[#UniversalSuggester]]

== User convenience ==
[[#Maps]] shows places on maps

[[#GeoData]] ability to attach coordinates to article and publish them via the HTTP API

[[#Lingo]] - tooltip pop-ups that explain terminology and abbreviations on the site.

[[#FaviconLink]] places the favico image of a site before the link.

== Sysop(presseur)ator convenience ==
[[#CheckUser]] 

[[#Replace Text]] allows text manipulation by plaintext or regex affecting articles or article names

= Implementation types of extensions =

The implementation strategy(s) employed in building this extension. This parameter is used to create categories that help programmers find examples of various MediaWiki specific implementation strategies or patterns. Although the values of this parameter sometimes coincide with the use case or purpose of an extension, that is not reason for this parameter. If the values you have chosen for this parameter do not adequately identify the purpose or possible use cases, we recommend you add additional category links as needed.

* [[mw:parser]] - catchall for uncategorized parser extensions. If you have written a parser extension, please use one of the following more specific types:
**[[mw:link]] - customized link markup, e.g. [[mw:...]]
**[[mw:parser function]] - custom parameterized template markup, e.g. {{#name: ... }}
**[[mw:tag]] - custom XML tag markup, e.g. <tagname>...</tagname>
**[[mw:variable]] - custom unparameterized template markup, e.g. <nowiki>{{NAME}}</nowiki>
**[[mw:extended syntax]] - Extensions that add non-standard wiki syntax (i.e. not tags, parser functions, or variables).
    
* [[mw:access]] - catchall for user access extensions, that is, extensions that create, authenticate, grant permissions, revoke permissions, or monitor the activity of users. If you have written an access extension, please use one of the following more specific types:
**[[mw:user activity]] - extensions that monitor user activity (logins, logouts, new user creation, etc.)
**[[mw:user identity]] - extensions that create and delete users, and/or verify the identity of a user
**[[mw:user rights]] - extensions to the rights management system, e.g. changes to the way rights are assigned, API, maintenance tools (does not include extensions that merely name the rights needed to use the features of that extension; for this purpose use the rights parameter)

* interface - catchall for uncategorized user interface extensions.
**[[mw:media]] - extensions that permit the embedding of multimedia content on wiki pages by registering a file extension with $wgMediaHandlers.
**[[mw:mywiki]] - extensions that provide infrastructure so that users may personalize their MediaWiki experience and/or assist in the management of that infrastructure
**[[mw:notify]] - extensions that email users, broadcast messages and provide other forms of community notification
**[[mw:page action]] - extensions that enhance or modify page actions. This includes anything that implements an action that reads, writes, searches for, creates, renames, deletes, redirects or discusses a page. It does not include rights (use user rights) or logs (use user activity).
**[[mw:search]] - extensions that search through and select articles for users.
**[[mw:skin]] - extensions adding CSS or JavaScript, or implementing hook functions to change the look and feel of MediaWiki via the skins framework.
**[[mw:ajax]] - extensions that use Ajax programming techniques.
**[[mw:special]] - extensions that subclass the SpecialPage class, use one of its hooks, or patch one or more functions in SpecialPage.php. See Manual:Special pages for more information.
    
* [[mw:other]]
**[[mw:api]] - extensions that add a new API module or extend a core API module.
**[[mw:hook]] - Hook extension - defines a new hook - see hook1, etc. below if you want to define hooks used by your extension

| <tt>'''[[mw:Extension:HashTables]]'''</tt> 
| Ability to make [[w:hash table]]s from template-data and to fill templates with data from hash tables. Enhances the parser with hash table functions and a function to store all parameters given to a template.

| This combined with storing and fetching to/from database so that database maybe manipulated from wiki and the wiki manipulated from the database. In some tasks [[#Arrays]] will be much more efficient, but as a catch-all way of storing values in templates in articles hash tables are an excellent idea. 
| [[mw:Parser function]]
| Tested on 1.17
| BINGO! Now we need only a way to store these in a database and fetch them from the database and we're set for a system that we can edit wiki and get stored in database and edit database and wiki get affected. Naturally using [[#Arrays]] can be much more efficient then a hash table when there is much sequential access of values / keys tables .. Using a hash table to store all things and no arrays certainly makes much more sense then using an array to store all things and no hash tables.

| NewArticleTemplates is an Extension that allows you to automatically prefill text of new pages with the contents of other predefined wiki-pages. It is possible to distinguish between namespaces and specify a different text for new subpages. Obviously does what it says. Enables per-namespace pre-loadable ( into the edit box ) texts for new articles i.e. we can have a skeleton for creating a new [[product]], [[brand]], [[company]], [[area]], [[country]] and [[NGO]] etc. no need to [[avoid copy-paste|copy-paste]]. Whether the template given for an article can be given if not all things are split into separate namespaces is possible is not know.

| <tt>'''[[mw:Extension:Semantic Expressiveness]]'''</tt> 
| Semantic Expressiveness is an enhancement for Semantic MediaWiki. Its main feature is to introduce a new syntax for inline short queries. The purpose of this simplest form of inline query is to provide a powerful tool for fighting redundancies within the wiki. Without Semantic Expressiveness it is customary to declare properties in one place but using the same information again all over the same article or on other pages as simple text representation. With Semantic Expressiveness it is possible to use simple references in form of a new syntax to place the same information in various places without writing redundant information. This way if the property changes, the information will update itself all over the wiki wherever the new syntax is in place.
