This document discusses using Semantic MediaWiki (SMW) to create a knowledge base for the CAF-Network.eu project. SMW allows adding structured data and semantic annotations to wiki pages. It outlines how SMW can be used to create pages about the Common Assessment Framework (CAF), link them to external vocabularies, and query the data in various formats. Reusing existing public sector vocabularies from the EU is recommended to align the project with linked open data standards.

4. CAF – Common Assessment Framework
 CAF improves public sector
organisations through self-assessment
and contributes to Good Governance.
 Quality management tools based on
TQM and EFQM® models.
 Promoted by European Public
Administration Network (EUPAN)
1. Self-assessment
2. Improvement plan
3. Effective CAF-User

5. CAF Knowledge
 Knowledge about CAF in general including the latest (5th) revision 2020.
 Detailed knowledge about 9 criteria and 28 subcriteria
 Knowledge about the CAF process and implementation
But also
 Who uses CAF?
 Who can I contact?
 What tools do support the process?
 Where can I find the best information?

10. What is Semantic MediaWiki (SMW)?
• open source project:
– www.semantic-mediawiki.org
– https://github.com/SemanticMediaWiki
• the „swiss army knife“ for data and semantics
• built on the MediaWiki ecosystem:
the wiki engine that powers Wikipedia
can be used for much more than just wikis…
10

11. MediaWiki + SMW + more extensions
• collaborative editing
• version history of every edit
• no backend:
everything is a wiki page
• structure via categories and
namespaces
• API
• …
• structured data
(Web database)
• result lists and formats
via {{#ask:}} queries
• Semantic Web standards
• triplestore support
• API
• …
• online forms for data entry
• more visualizations
• responsive skin
• authentication
• image annotation
• SPARQL
• …
11

12. Semantic MediaWiki storage options
SQL Store (default)
• extra tables in the
SQL store of
MediaWiki
ElasticStore
• search engine, not a
storage backend
SPARQL/RDF Store
• custom, default
• Virtuoso
• Blazegraph
• Fuseki
• Sesame
• 4store 12
easy (to install) harder to install but more powerful

13. Internal query language

{{#ask:
[[Category:Practices]]
[[Country::Austria]]
|?Organisation
|?Coordinates
|format=table
}}

14. Internal query language
{{#ask:
[[Category:Practices]]
[[Country::Austria]]
|?Organisation
|?Coordinates
|format=map
}}

15. > 70 result formats, supporting
MediaWiki templates
|format=moderntimeline
|format=calendar
|format=median
|format=D3chart
|format=gantt
|format=tagcloud
|format=json
|format=rdf

18. 5 Star-Schema of Linked (Open) Data

19. Linking to external identifiers
 Define a property
 Assign datatype „External identifier“
– Links to external ids
 Look for other identifiers
– ORCID https://orcid.org/
– GND
– …..
[[Has type::External identifier]]
[[External formatter uri::
http://www.wikidata.org/entity/$1]]

20. Using External Vocabularies
1. Add a page MediaWiki:Smw import foaf
2. Instead of local datatype declarations, use
[[Imported from::foaf:familyName]]
on the property page (e. g. Property:Last name)
Ad more vocabulary terms any
time…

21. Unique IDs in MediaWiki
 Every page has a unique page ID
 You can display it and use it to link to a
page without using the page name (that
could change over time)
 https://www.caf-network.eu/?curid=185

22. Core Public Service Vocabulary
CAF-Network.eu
 Address
 Country
 City
 Organisation
 Person
 Level of government
 Organisation size
 Organisation type
 Website
 Year
 ZIP
