Generating an Ontology Speciﬁc Editor Hannes Niederhausen, Sven Windisch, Lutz Maicher Topic Maps Lab University of Leipzig Leipzig, Germany 29.10.2010/SEMAPRO2010 Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 1/24

Introduction The name: Hannes Niederhausen Working at the Topic Maps Lab Topic Maps Lab: Research Group at the University of Leipzig Developing Tools and Applications for Topic Maps Website: http://www.topicmapslab.de Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 2/24

Outline Background: Topic Maps Background: Onotoa Motivation Software Stack of the Generated Editor Example Summary Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 3/24

Background: Topic Maps I The ISO-Standard Subject centric semantic technologies ISO Standard Family: Core: TMDM ISO 13250-2 Other parts: Serialisations, Query and Schema Language Topics represent anything like persons, web pages or abstract types like colours Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 5/24

Background: Topic Maps II Topics Topic has identifier: item identifier IRI to identify topic map element inside a topic map subject identifier IRI to description of represented subject subject locator IRI which leads to the represented subject Topic has names - typed using other topics Topics has occurrences - typed using other topics Topics can be typed by other topics Example Topic: "http://topicmapslab.de/people/Hannes_Niederhausen" has the Name "Hannes Niederhausen" of type "wiki:Fullname" and is a "wiki:Person". Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 6/24

Background: Topic Maps III Associations Associations connect topics Associations are typed with topics A topic plays a role in an association Roles are also typed with topics Example: "Hannes Niederhausen" plays role "Employee" in association "works for" Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 7/24

Background: Onotoa Onotoa is schema editor for Topic Maps Plug-in based application based on Eclipse RCP Provides export to Topic Maps Constraint Language (ISO 19756) Provides schema extensions, called annotation Current beta: http://onotoa.topicmapslab.de/beta Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 9/24

Motivation Topic Maps can be created by: Merging different topic maps A mapping of non-topic-map data to a topic map Entered by authors For the latter an editor is needed Model-Driven-Development generates source code based on model description like UML Question: Why not generate the domain model based on a Topic Maps schema? After generating the domain model the next logic step was to generate a whole application. Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 11/24

Example Domain Attendees of SEMAPRO2010 and their employers If an attendee gives one or more presentations persist it too Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 16/24

Example Schema Figure: The domain in the abstract domain diagram of Onotoa. Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 17/24

Example Generator Annotations Annotate types to generate categories Set names to use as object serialisation Do not generate ﬁelds in talk and company for persons Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 18/24

Example Generated Editor Figure: The generated application with some data. Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 19/24

Editor Features Edit topic maps instances Store topic maps in a database or ﬁles Easy to modify by generating a new editor model Extendable with other Eclipse Plug-ins Application is platform independent Upload the topic map to Maiana (http://maiana.topicmapslab.de) Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 20/24

Summary Generate an editor inside Onotoa very easy Building the application without any knowledge of Eclipse framework Outlook Support more Topic Maps constructs, like reiﬁcation and scope Provide layout conﬁguration Hannes Niederhausen, Sven Windisch, Lutz Maicher (Topic Maps Lab) 29.10.2010/SEMAPRO2010 22/24
