Users
need solutions
for use cases,
but cannot talk
IT language
are not up to
date regarding
IT possiblilities
IT
knows IT
solutions,
does not
understand
use cases
enough
Dilemma in IT projects

Wikis and Web 2.0 – „Wikimania“
wikis became well-known through Wikipedia
technologically, nothing groundbraking
Hypertext system, usually with database
simple user interface, full text search
social software
everyone can make changes: initial idea of WWW!
wisdom of the crowd
shared knowledge creation and quality management
knowledge creation „on the fly“
no need to pre-define structure
links to non-existing pages generate ideas for others
Wiki Software:
> 100 Wiki engines on www.wikimatrix.org
Most of them Open-Source: no license cost
some like MediaWiki very stable with big community

Wiki vs. Document Management
Documents = DMS
Word
Excel
PowerPoint
Approval
Electronic Signature,
User rights
(File system), Sharepoint,
Fabasoft, Alfresco…
Content = Wiki
Content of documents
Text with categories
Database functions with
forms
Document upload as an
exception

www.kdz.or.at
Wiki vs. Content Management
Control = CMS
Access control on
different content types
(Filesystem), Sharepoint,
Drupal, Typo3, Joomla…
Transparency = Wiki
Everyone can view/edit
everything
Restrictions on actions
(who can view/edit), not
on content types (what)
Changes visible
Easy rollback
Advantage: enables cultural
change!

Strenghts and Weaknesses of
Wikis
Wikis are great for text…
easy to use, easy to edit
full text search
Categories to organise pages
Wikis have weaknesses for knowledge management!
no data, only text: 995 32
no relations, just links: Tbilisi —> Krakow
no querying of data
lack of structure leads to manual effort
manual edited lists (List of danube bridges, list of Autrian museums by city)

Semantic MediaWiki
leaves your MediaWiki installation intact
no patching, just a (bunch of) MW extension(s)
already existing unstructured content can stay as it is or be
transformed
gives you all the tools you need for a
collaborative web database
entering data and text
representing data and text within the wiki
visualise data
re-use/export data outside the wiki
everything is done through configuration
Attributes, Forms, Templates, Filters… are wiki pages

Don underestimate organizational
success factors
content that users need
not to be confused with content that organization whishes for!
culture of trust and appreciation
everybody can see everything and change everything
users can‘t do anything wrong – errors can be undone easily
motivation and pressure
managers need to be role models and actively support the project
no redundant content: turn off alternative sources!
obligations to use the wiki
quantity and quality of content
Initial content is important! no-one feels at home in empty rooms
usability und fun
design, acces to wiki, (single-sign-on, RSS-feeds, intranet)
forms for data input, avoid too much wikitext for regular users
