Presentation of paper: Lloyd Rutledge. “From Ontology to Wiki: Automating Generation of Semantic Wiki Interfaces from Given Ontologies with Cascading Fresnel Style”, in Workshop on Semantic Web Collaborative Spaces (SWCS2013), Montpelier, France, May 27, 2013. http://www.swcs2013.org/program

1. From Ontology to Wiki
Generating Cascadable Default Fresnel
Style from Given Ontologies for Creating
Semantic Wiki Interfaces
Lloyd Rutledge

2. Summary
• Input: Semantic Web ontology (data model)
• Output: Semantic wiki with form-based input
• Academic results
– Mapping of abstract data modeling to interface
• Practical results
– Efficient quick setup of wiki interface for entering data for a given
ontology
• Related topic areas
– Model-driven Development
– Ontology-alignment
– Style in Web technologies

3. 3
Contribution
• Mapping from Semantic Web ontologies to default interface style
– Uses W3C technology Fresnel for Semantic Web interfaces
• Techniques for fine tuning default with additional Fresnel
• Mapping from Fresnel to form-based semantic wikis
– Fine tunable default style facilitates semantic wiki startup
– This Fresnel implementation adds facilitated data entry
• Implementation: OWL Wiki Forms (OWF)
– Open source MediaWiki extension

5. • Semantic MediaWiki extension
• Infobox-like templates for data browsing
• Forms for data entry
• Primitives for building ontology-based
interface

11. Cascading Style Sheets (CSS)
• Specifies how an XML document should appear
– Mapping from XML to presentation display model
• Separation of style from content
– Reuse of one centralized style for multiple documents
• “Cascading” is layered building up of style from general to specific
• Default style sheets for HTML
– And SVG, MathML, etc.
– Thus default style for a given domain of XML
• Effectively a default stylesheet for XML
– How XML appears on a web browser

12. Model-driven development
from OU course T37121 Model-driven development workbook

14. Model-driven Development concepts
• Default/prototype system interface from data model (ontology)
• Whole system development driven by development of data model
– And feedback from default interface guide model development
– But Semantic Web has more reuse of existing ontologies
• Various ways of overriding or tailing default interface
– In OWF Wiki Forms:
• Cascading ontology
• Cascading Fresnel
• CSS
• Wiki templates at standard locations

Domain-independent default for browser (Longwell)
With (handmade) Fresnel style

16. Fresnel: RDF interface in RDF
• Specifies how RDF is display
• Separates style from content: like CSS for XML
• Also in RDF

29. Next steps
• Minimizing non-default style specification
– Default for ontology through non-default style to target interface
– Evaluate as distance from default to target
• Standard sort?, “triple distance”?
– Most widely used ontologies and interface
• Non-default style layer
– Namespace data
– Order of properties in boxes: via Fresnel
– CSS via Fresnel
• Cascading: Ontologies, CSS, Wiki templates
• Extend Fresnel for Semantic Forms interface components
