The following are MediaWiki extensions based around Semantic MediaWiki, that are not being maintained and will most likely not work if you try to use them with a recent version of MediaWiki. In some cases they were abandoned because their functionality was adopted by a larger extension (including, some of the time, Semantic MediaWiki itself), while in other cases the creators of the extension simply stopped developing it.
For a list of extensions that ''are'' being maintained, see [[Help:SMW extensions]].
==FolkTagCloud==
''This extension was replaced by the 'tagcloud' format in [[mw:Extension:Semantic_Result_Formats|Semantic Result Formats]].''
[[mw:Extension:FolkTagCloud|FolkTagCloud]] adds an SMW property for tagging wiki pages with user-defined labels and a parser tag for displaying these "FolkTags" in a tag cloud.

==Question API==
[[mw:Extension:Question_API|Question API]] creates a special page that lets a wiki determine the veracity of a set of data before adding it to the wiki. If administrators have an automated source of information they want to add as semantic data to the wiki, but want to make sure that each piece of information is correct, they can pass the data in to Question API; the system phrases each piece of information as a yes/no question, and if a user clicks to indicate the information is correct, the system adds this piece of data into the wiki.
This experimental extension was used for exploring possibilities of supervised information extraction in (semantic) wiki. It was discontinued after completing these experiments.

''This extension was replaced by [[mw:Extension:Semantic_Maps|Semantic Maps]].''
[[mw:Extension:Semantic_Google_Maps|Semantic Google Maps]] allows for the use of Google Maps for three purposes: (1) to display a single point of type [[Help:Type Geographic coordinate|Geographic coordinate]] on a page, (2) as an input within a Semantic Forms form to let users enter such a value, and (3) to display a set of pages on a map using an #ask query, based on some property they all share of type Geographic coordinate.

==SMW OntologyEditor==
The SMW OntologyEditor is an extension of Semantic MediaWiki and was developed as part of the ACTIVE project (http://www.active-project.eu/) in order to enable the development of lightweight ontologies. The focus of the editor is to provide an easy understandable interface to develop ontologies and to ensure consistency of the knowledge base by providing a set of knowledge repair algorithms.
The main features are:
* Development of lightweight ontologies (vocabularies, categories, properties, elements)
* Import/export of OWL/XML files and folksonomies
* Knowledge repair algorithms (errors, redundancies, inconsistencies)

== SMW+ extensions ==
The set of extensions collectively known as "SMW+" was developed and maintained by the Ontoprise corporation. In April 2012 Ontoprise went bankrupt, and in December 2012 the homepages for all of these extensions became inaccessible. It could be that in the future some or all of these extensions will once again be maintained, but for now, these extensions, at least in their open-source form, must be considered defunct.
===Halo===
[http://wiki.ontoprise.com/smwforum/index.php/HaloExtension_Product_Information Halo] enhances SMW by providing intuitive graphical interfaces that facilitate the authoring, retrieval, navigation and organization of semantic data in SMW.
It basically comprises:
* Semantic Toolbar, allowing to quickly inspect, create and alter the semantic annotations of a wiki article
* Advanced Annotation Mode, for annotating contents semantically in a WYSIWYG-like manner without having to cope with the wiki source text
* Auto-completion, suggesting entities or data existing in the wiki while typing (e.g. when annotating in the wiki-text or filling in input fields)
* Graphical query interface, empowering users to easily compose queries and preview query results with different output formats
* Ontology browser, enabling intuitive browsing and changing of the wiki's ontology and lookup of instance and property information
The pre-configured and ready-to-use bundle of the Halo extension (including MediaWiki, Semantic MediaWiki and other useful extensions) is also known as ''SMW+''.

===Rule Knowledge===
The [http://www.smwplus.net/index.php/Help:Rule_Knowledge_Extension Rule Knowledge extension] provides a graphical editor for creating logical rules. Rules allow you to state complex interrelations and can be exploited for inferring knowledge (via a connected triple store). The extension supports the authoring of calculation, definition and property chaining rules.

===WYSIWYG===
The [http://smwforum.ontoprise.com/smwforum/index.php/WYSIWYG_extension WYSIWYG extension] (based on the FCKeditor) provides a WYSIWYG editor for authoring rich text contents. It enables the insertion of semantic annotations (in the rendered article), but also the convenient creation of dynamic content by embedding templates, web service calls or semantic queries.

===Enhanced Retrieval===
[http://www.smwplus.net/index.php/Help:Enhanced_Retrieval_extension Enhanced Retrieval] is based on 'Solr' and provides a powerful search engine for your wiki. It comes with auto-completion, spell-checking ("did you mean" feature) and advanced search functionalities such as fuzzy and path search. The search covers full text contents (also from uploaded PDF and Word documents) as well as elements from the ontology, presenting the results on a unified interface.

===Semantic Gardening===
[http://www.smwplus.net/index.php/Help:Semantic_Gardening_Extension Semantic Gardening] allows you to detect inconsistencies (such as schema level violations) or peculiarities in your wiki's semantic data via automatic bots. Furthermore it provides an import and export functionality for OWL ontologies.

'''First released:''' April 2009
===TreeView===
[http://www.smwplus.net/index.php/Help:TreeView_Extension TreeView] displays a hierarchical view of wiki elements of your choice such as categories, articles or semantically annotated data contained in the wiki. With Semantic Treeview you define once your navigation structure or index and then let it take care of the automatic tree population. The tree will be displayed along side the actual wiki page.

'''First released:''' February 2009
===Triple Store Connector===
The [http://www.smwplus.net/index.php/TripleStore Triple Store Connector] allows to use a triple store as semantic data backend. With a linked triple store you can benefit from its advanced reasoning functionality and query the wiki knowledgebase via SPARQL (from remote). The following connectors can be obtained:
* TripleStoreConnector Professional including Ontobroker (commercially available, better scalability and expressivity)
* TripleStoreConnector Basic including Jena (for free)

===Access Control List===
[http://www.smwplus.net/index.php/Help:Access_Control_List_extension Access Control List] is a powerful extension for protecting single wiki pages, articles in categories or namespaces and values of semantic properties. Access can be restricted for individual users or entire user groups. An intuitive GUI allows easy administration of access rights and user groups. It can also be connected to an external LDAP server and re-use the users and groups defined there.

===Semantic Notifications===
[http://www.smwplus.net/index.php/Help:Semantic_Notifications_Extension Semantic Notifications] keep you informed about changes in your semantic data by sending notifications via email. This extension complements MediaWiki's 'watch page' functionality, which allows only to watch single pages, but no data scattered across several pages.

'''First released:''' April 2009
===Data Import===
The [http://www.smwplus.net/index.php/Help:Data_Import_Extension Data Import extension] enables users to integrate external data into the wiki in two different ways. First, the Web Service component allows to call external SOAP or RESTful web services from within the wiki and embed the results in wiki pages. Second, the Term Import framework allows to import data (e.g. data from CSV files or emails) as wiki articles.

===Rich Media===
[http://www.smwplus.net/index.php/Help:Rich_Media_Extension Rich Media] allows the easy upload and embedding of media files such as documents, images, videos and audio files into the wiki. Media files can be attached to related articles, thus preserving the context of the files. Furthermore a meta-data set is provided, which can be used for querying uploaded media files.
