Semantic MediaWiki

Semantic MediaWiki (SMW) is a free extension of MediaWiki that helps to search, organize, tag, browse, evaluate, and share the wiki's content. While traditional wikis contain only texts which computers can neither understand nor evaluate, SMW adds semantic annotations that bring the power of the Semantic Web to the wiki.

There are many of other extensions based on SMW, for example Semantic Forms, which allows users to add, edit and query data using forms.

Tips and Tricks

show on select

The "div" container must be placed accoring to HTML standard. So, it will not work to just enclose rows of an table (to be hided or shown). You need to create a separate table in this case.

Example: Form:Glossary

{{{for template|Glossary_Definition|multiple|label=Definition of term|add button text=Add a new definition}}}
{| class="formtable" {{prettytable}}
|-
| Approval Time: {{#info: Time format: 24h.}}
| {{{field|ApprovedTime|input type=datetime|property=PropGlossaryApprovedTime}}}
|}
<div id="showApprovedByAndTime">
{| class="formtable" {{prettytable}}
|-
| Approved By: {{#info:user name in '''lower''' case (first letter can be upper case).}}
| {{{field|ApprovedBy|autocomplete on namespace=User|property=PropGlossaryApprovedBy}}} (''autocomplete'')

|-
| Approval Time: {{#info: Time format: 24h.}}
| {{{field|ApprovedTime|input type=datetime|property=PropGlossaryApprovedTime}}}
|}
</div>
{{{end template}}}

Update problems

When an error occurs running SMW_refreshData.php like

PHP Fatal error:  Call to a member function isSpecialPage() on a non-object in 
./extensions/SemanticResultFormats/formats/tagcloud/TagCloud.php on line 80

it seems to be related to a certain extension, you can try to (temporarily) disable the extension or a feature.

In this case, you can (temporarily) disable the tagcloud format in

./SemanticResultFormats/SemanticResultFormats.settings.php
