Open Governmental Data –
and ideal testbed for Linked Data?
 Close cooperation with W3C eGov IG, OKFN’s OpenEUdata, PSI & grassroots
efforts
 CKAN.org | OKFN’s EuOpenData group |
ICT2010 Networking Session
 UIs and Personalization
o individual mashups of data with other sources
o Notification/subscription service based on personal prefs
o Transparency wishlists, upload revisions, derivates
o create and publish queries, reports and visualizations

Achievements
1. Extension of the Web with a
data commons (13.1 B facts
2. vibrant, global RTD
community
3. Industrial uptake begins (e.g.
BBC, Thomson Reuters, Eli
Lilly)
4. Emerging governmental
adoption in sight
5. Establishing Linked Data as a
deployment path for the
Semantic Web.
LOD achievements and challenges
 Challenges
1. Coherence: Relatively few,
expensively maintained links
2. Quality: partly low quality data
and inconsistencies
3. Performance: Still substantial
penalties compared to relational
4. Data consumption: large-scale
processing, schema mapping
and data fusion still in its infancy
5. Usability: Missing direct end-
user tools and network effect
These issues are closely related and
need to be treated in an integrated,
holistic fashion – LOD2 ;-)
• Web - a global, distributed platform for data, information and knowledge integration
• exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web
using URIs and RDF

1. Semantic (Text) Wikis
• Authoring of semantically
annotated texts
2. Semantic Data Wikis
• Direct authoring of
structured information
(i.e. RDF, RDF-Schema,
OWL)

Most RDF and ontology editors provide forms
for authoring structured information
• users don’t have to deal with syntax 
• Still they have to be acquainted with the
RDF or ontology data models
RDFauthor aims to hide syntax and data
model by making RDFa views editable
RDFauthor – empower end users to author RDF

• RDFa annotated Web page (+ SPARUL endpoint)
• Integrated RDFauthor JavaScript library
• Authoring is triggered by connecting events (i.e.
click of an edit button) with RDFauthor functions

• unified method, for both data evolution and ontology
refactoring.
• modularized, declarative definition of evolution patterns is
relatively simple compared to an imperative description of
evolution
• allows domain experts and knowledge engineers to amend the
ontology structure and modify data with just a few clicks
• Combined with RDF representation of evolution patterns and
their exposure on the Linked Data Web, EvoPat facilitates the
development of an evolution pattern ecosystem
• patterns can be shared and reused on the Data Web.
• declarative definition of bad smells and corresponding
evolution patterns promotes the (semi-)automatic
improvement of information quality.

Take home messages
• Two kinds of Semantic Wikis: Data and Text
oriented ones
• Semantic Wikis lower the entrance barrier
to publishing and interlinking LOD data
• Different LOD aspects such as knowledge
base evolution, coherence (pingback), data
importing, browsing & exploration can be
facilitated by a Semantic Wiki
Creating Knowledge
out of Interlinked Data
Semantic Wikis and the Web of Data 02.09.2010 Page 41 http://lod2.eu
• Establish a network effect around LOD
• Create the LOD washing machine (possibly
with Semantic Wiki’s as an engine)
• Target Enterprise Information Integration,
Open Governmental and
Scientific Data
• From eat-your-own-dogfood to
convince-you-grandma
What should we do in the future?

Coherence: Relatively few, expensively maintained links 2. Quality: partly low quality data and inconsistencies 3. Performance: Still substantial penalties compared to relational 4. Data consumption: large-scale processing, schema mapping and data fusion still in its infancy 5. Usability: Missing direct end- user tools and network effect These issues are closely related and need to be treated in an integrated, holistic fashion – LOD2 ;-) • Web - a global, distributed platform for data, information and knowledge integration • exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF July 2007 April 2008 September 2008 July 2009
