The original idea of SMW: make data and
relations inside a wiki readable

Wikis and Data in 2014
extract structured information from
Wikipedia and make this information
available on the Web
free knowledge base that can be
read and edited by humans and
machines alike… central storage for
the data that may be accessed by
the client Wikis
lets you store and query data within
the wiki's pages. Turns a wiki into a
powerful and flexible knowledge
management system.

Strenghts and weaknesses
28.10.2013 · Seite 19
ITS A GREAT TOOL!
all the benefits of
(media)wiki
web database with
configuration, no
programming
forms and many
other extensions
import/export of
data, result formats
community support
…
no good, usable skins
https://www.mediawiki.org/wiki/Skin:Chameleon
no WYSIWYG editor
https://www.mediawiki.org/wiki/VisualEditor
no access control
https://www.mediawiki.org/wiki/Extension:Acces
s_Control_List
no crowdfunding / poor
marketing
some dead extensions
some bugs don‘t get fixed
not usable for complex data
structures
www.kdz.or.at
Conclusion
SMW is (still) not well known
project references lead to further use cases
when people see what can be done, they like it
people think of wikis and don‘t realize the
potential of SMW as a strategic platform
access control is always requested
SMW is NOT just semantic web project anymore
SMW has potential to become THE OpenGLAM
tool: de.slideshare.net/krabina/semantic-mediawiki-als-openglam-tool
SMW has a lot more future potential …
