What we have
• TMDM• TMAPI (old and new)• TMO• BSCPL• AR
5
The Challenge
• TMDM offers ontological flexibility• TMAPI provides interface to TMDM
• It’s not domain-specific• We need to get closer to the
business
Current development approachesare too slow
6
7
What has been done before?
• Most of us were just using someTMAPI-like interface
• NetworkedPlanet made Topic Map Objects
• Bogachev had some concepts... ...but did not implement them
8
What are others doing?
• Holidays• Traveling• Object-Relational Mapping
• Active Record
• Throw more programmers at the problem (and that doesn‘t scale)
We have a problem
9
Every programming problem can be solved with another layer of abstraction,except the problemof too many layers of abstraction.

Domain Modeling
• investigate the domain of the customer
• find out what is important for the use case
• define domain model by stating• all subject types• their characteristics• and associations to other subjects
17
After modeling...
• ideally, you should have some administrative CRUD interface now
• add domain-specific shapes for theend-user portal
[Not covered here: the dynamic perspective]
18
ActiveTM
• ActiveTMML• the modeling language
• ActiveTM• a prototypical implementation• using Ruby and RTM
• Some assorted scripts which generate• Migrations, AR-Models, ...
19
What does it look like?
class Person < ActiveTM::Base topic_map "http://psi.example.com/" psi "http://psi.example.com/ontology/person"
name :firstname names :middlenames name :lastname occurrence :age, :datatype => "xsd:integer" has_one :country, "inhabitant", "country-
inhabitant", :class => :Country
def fullname "#{firstname} #{lastname}" endend
20
How is it used?
p = Person.create("johndoe")p.firstname = "John"p.add_middlename "George"p.lastname = "Doe"p.age = 25p.save
21
Can I use it?
No.Not yet.Sorry.

• create domain-specific portals• using context-specific Shapes• generate administration interfaces• using just the list of characteristics
we want to have in list, show, and edit-view
