OUTLINE

• 1. Introduction
• What is the main purpose for my project
• 2. Selections
• Things have to be decided before
• 3. Coding
• OWL API UML API
• 4. Further plan for next five coding weeks
• What is next
• 5. References

1. Introduction

• What graphical tools we have for protégé
• ---- OWLViz

1. Introduction

• What graphical tools we have for protégé
• OWLVisualization, a good way to represent
• parent-child, Superclass-Subclass
• What is more we want to see?
• Not only the parent-child
• But also more relations

5
1. Introduction

• Why UML ?
• Unified Modeling Language ---- by OMG
• Familiar with more users and can be recognized
• Many tools can be used to build
• UML tools or UML API By searching in Google

6
2. Selections

• Which classes properties to show and
• How to choose
• Select classes ngt1 and show links
• Select properties ngt2
• At the left side of Protégé

7
2. Selections

• How to show
• Colors, type of lines and the style of the boxes,
  all of them can be the choice to distinguish the
  classes, attributes and associations.
• Here are two different versions to represent
  Pizza.owl

8
2. Selections

• Layout and how much to show

3. Pre-coding
Basic OWL API
UML API

3. Pre-coding

3. Coding

• Baby example from UML API

15
3. Coding

• Some arrow examples

16
3. Coding

• The interface OWLOntology.java lists everything
• getReferencedClasses()
• getReferencedObjectProperties()
• getReferencedIndividuals()
• getSubClassAxiomsForRHS(OWLClass cls)
• getDisjointClassesAxioms(OWLClass cls)
• Etc.

3. Coding

4. Further planning

• Make the boxes clickable as OWLViz
• See relations of one class more clear among the
  map
• Search more UML API version
• Now what we have is not the standard UML way
  what we expect

19
4. Further planning

• Try to make it more UML way

20
4. Further planning

• Build UML plug-in for protégé
• How to show less
• Make the classes and properties selectable
• Now what have is show all the things in owl
• At the left side of OWLUML in protégé
