href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/MediaWiki" title="MediaWiki">MediaWiki</a> – the wiki application best known for powering Wikipedia – that helps to search, organise, tag, browse, evaluate, and share the wiki's content. While traditional wikis contain only text which computers can neither understand nor evaluate, SMW adds <i>semantic annotations</i> that allow a wiki to function as a collaborative database. Semantic MediaWiki was first released in 2005, and currently has over ten developers, and is in use on hundreds of sites. In addition, a large number of <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Help:SMW_extensions" class="mw-redirect" title="Help:SMW extensions">related extensions</a> have been created that extend the ability to edit, display and browse through the data stored by SMW: the term "Semantic MediaWiki" is sometimes used to refer to this entire family of extensions. </p> <div id="toc" class="toc"><div class="toctitle" lang="en" dir="ltr"><h2>Contents</h2></div> <ul> <li class="toclevel-1 tocsection-1"><a href="#Why_Semantic_MediaWiki.3F"><span class="tocnumber">1</span> <span class="toctext">Why Semantic MediaWiki?</span></a></li> <li class="toclevel-1 tocsection-2"><a href="#Where_SMW_can_help"><span class="tocnumber">2</span> <span class="toctext">Where SMW can help</span></a></li> <li class="toclevel-1 tocsection-3"><a href="#Who_is_using_Semantic_MediaWiki.3F"><span class="tocnumber">3</span> <span class="toctext">Who is using Semantic MediaWiki?</span></a></li> <li class="toclevel-1 tocsection-4"><a href="#More_information"><span class="tocnumber">4</span> <span class="toctext">More information</span></a></li> <li class="toclevel-1 tocsection-5"><a href="#Contact_and_user_support"><span class="tocnumber">5</span> <span class="toctext">Contact and user support</span></a></li> </ul> </div> <h2><span id="Why_Semantic_MediaWiki?"></span><span class="mw-headline" id="Why_Semantic_MediaWiki.3F">Why Semantic MediaWiki?</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20190911090637/https://www.semantic-mediawiki.org/w/index.php?title=Help:Introduction_to_Semantic_MediaWiki&action=edit&section=1" title="Edit section: Why Semantic MediaWiki?">edit</a><span class="mw-editsection-bracket">]</span></span></h2> <p>Wikis are a great tool for collecting and sharing knowledge in communities and organizations. This knowledge is mostly contained within texts and multimedia files, and is thus easily accessible for human readers. But though wikis are very good for storing and retrieving individual facts, they are less useful for getting queried or aggregated information. As a simple example, let's say you use a wiki that stores information about projects related to your organization. You have the following simple question: </p> <dl><dd>"What are the active projects that were started in 2012?"</dd></dl> <p>This should be an easy question to answer, but in fact it's not - you would have to read through all of the pages about projects every time you wanted to answer the question. Text searches won't necessarily help. Categories could help to some extent, although they're not an ideal tool and maintaining them can become complex (see below). And there doesn't exist an artificial intelligence tool that could help with this task either. </p><p>Semantic MediaWiki enables wikis to make their knowledge computer-processable, so that you can find and display the answer to this question - and to many more. </p> <h2><span class="mw-headline" id="Where_SMW_can_help">Where SMW can help</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20190911090637/https://www.semantic-mediawiki.org/w/index.php?title=Help:Introduction_to_Semantic_MediaWiki&action=edit&section=2" title="Edit section: Where SMW can help">edit</a><span class="mw-editsection-bracket">]</span></span></h2> <p>Semantic MediaWiki introduces some additional markup into the wiki-text which allows users to add "semantic annotations" to the wiki. While this at first appears to make things more complex, it can also greatly simplify the structure of the wiki, help users to find more information in less time, and improve the overall quality and consistency of the wiki. Here are some of the benefits of using SMW: </p> <ul><li><b>Automatically-generated lists.</b> Lists and tables are a natural way to view information at a glance. In some cases, non-semantic wikis contain human-generated lists; Wikipedia itself has thousands, like "<a href="//web.archive.org/web/20190911090637/https://en.wikipedia.org/wiki/en:List_of_metropolitan_areas_in_Spain_by_population" class="extiw" title="wp:en:List of metropolitan areas in Spain by population">List of metropolitan areas in Spain by population</a>". These lists are prone to errors, since they have to be updated manually. Furthermore, the number of potentially interesting lists is huge, and it is impossible to provide all of them in acceptable quality. In SMW, lists are generated automatically <a href="https://web.archive.org/web/20190911090637/http://semanticweb.org/wiki/Africa" class="extiw" title="semweb:Africa">like this</a>. They are always up-to-date and can easily be customised to obtain further information.</li></ul> <ul><li><b>Visual display of information.</b> The various display formats defined by additional extensions, such as <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Extension:Semantic_Result_Formats" title="Extension:Semantic Result Formats">Semantic Result Formats</a> and <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Extension:Maps" title="Extension:Maps">Maps (formerly Semantic Maps)</a>, allow for displaying of information in calendars, timelines, graphs and maps, among others, providing a much richer view of the data than simple lists and tables would.</li></ul> <ul><li><b>Improved data structure.</b> MediaWiki wikis tend to make heavy use of categories for structuring data. While these are generally helpful, consider the category on Wikipedia called "<a href="//web.archive.org/web/20190911090637/https://en.wikipedia.org/wiki/en:Category:1620s_births" class="extiw" title="wp:en:Category:1620s births">1620s births</a>"; if the information in these pages were stored using SMW, these categories could be replaced by simple semantic values, reducing the need for a complex classification system. In addition, if semantic markup within the wiki is stored within templates, otherwise known as <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Help:Semantic_templates" title="Help:Semantic templates">semantic templates</a>, a wiki can easily gain a solid data structure. And the <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Extension:Page_Forms" title="Extension:Page Forms">Page Forms (formerly Semantic Forms)</a> extension lets administrators create forms for adding and editing the data within semantic templates, thus making the addition of semantic information even easier and more straightforward than using regular wiki text.</li></ul> <ul><li><b>Searching information.</b> Individual users can search for specific information by creating their own queries, supported via extensions like <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Semantic_Drilldown" class="mw-redirect" title="Semantic Drilldown">Extension "Semantic Drilldown"</a> and <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Extension:Page_Forms" title="Extension:Page Forms">Page Forms (formerly Semantic Forms)</a>.</li></ul> <ul><li><b>External reuse.</b> Data, once it is created in an SMW wiki, does not have to remain within the wiki; it can easily be exported via formats like CSV and JSON. This enables an SMW wiki to serve as a data source for other applications, or, in the case of enterprise usages, to take over the role that a relational database would normally play. Through the use of the <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Help:MediaWiki_extensions#External_Data" title="Help:MediaWiki extensions">External Data</a> extension, <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/SPARQL" title="SPARQL">SPARQL</a>, and other tools, one SMW-based wiki can even use the data from another, eliminating the need for redundancy between wikis. You can also query SMW's data from outside the wiki, via the API or an <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Help:Using_SPARQL_and_RDF_stores" title="Help:Using SPARQL and RDF stores">RDF triplestore</a>.</li></ul> <ul><li><b>Integrate and mash-up data.</b> Data contained in an SMW installation does not have to be an isolated store of information. Extensions such as <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Help:SMW_extensions#Data_Transfer" class="mw-redirect" title="Help:SMW extensions">Data Transfer</a> and <a href="/web/20190911090637/https://www.semantic-mediawiki.org/wiki/Help:SMW_extensions#External_Data" class="mw-redirect" title="Help:SMW extensions">External Data</a> empower you to integrate external data (coming e.g. from legacy systems, web services or linked data sources) and interrelate it with existing semantic data in the wiki. Thus, an SMW-powered wiki can serve as a central information hub in an IT landscape.</li></ul> <h2><span id="Who_is_using_Semantic_MediaWiki?"></span><span class="mw-headline" id="Who_is_using_Semantic_MediaWiki.3F">Who is using Semantic MediaWiki?</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/web/20190911090637/https://www.semantic-mediawiki.org/w/index.php?title=Help:Introduction_to_Semantic_MediaWiki&action=edit&section=3" title="Edit section: Who is using Semantic MediaWiki?">edit</a><span class="mw-editsection-bracket">]</span></span></h2> <p>Semantic MediaWiki has grown a long way from its roots as an academic research project.
