Background: Topic Maps IThe ISO-Standard

I Subject centric semantic technologies

I ISO Standard Family: Core: TMDM ISO 13250-2

I Other parts: Serialisations, Query and Schema Language

I Topics represent anything like persons, web pages or abstract types likecolours

Background: Topic Maps IITopics

I Topic has identifier:I item identifier IRI to identify topic map element inside a topic mapI subject identifier IRI to description of represented subjectI subject locator IRI which leads to the represented subject

I Topic has names - typed using other topicsI Topics has occurrences - typed using other topicsI Topics can be typed by other topicsI Example Topic: "http://topicmapslab.de/people/Hannes_Niederhausen"

has the Name "Hannes Niederhausen" of type "wiki:Fullname" and is a"wiki:Person".

Background: Topic Maps IIIAssociations

I Associations connect topics

I Associations are typed with topics

I A topic plays a role in an association

I Roles are also typed with topics

I Example: "Hannes Niederhausen" plays role "Employee" in association"works for"

Background: Onotoa

I Onotoa is schema editor for Topic Maps

I Plug-in based application based on Eclipse RCP

I Provides export to Topic Maps Constraint Language (ISO 19756)

I Provides schema extensions, called annotation

I Current beta: http://onotoa.topicmapslab.de/beta

Motivation

I Topic Maps can be created by:I Merging different topic mapsI A mapping of non-topic-map data to a topic mapI Entered by authors

I For the latter an editor is needed

I Model-Driven-Development generates source code based on modeldescription like UML

I Question: Why not generate the domain model based on a Topic Mapsschema?

I After generating the domain model the next logic step was to generate awhole application.
