TMDM offers ontological flexibility

TMAPI provides interface to TMDM

It’s not domain-specific

We need to get closer to the business

Current development approaches

are too slow

What has been done before? Most of us were just using some TMAPI-like interface NetworkedPlanet made Topic Map Objects Bogachev had some concepts... ...but did not implement them 

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

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

After modeling... ideally, you should have some administrative CRUD interface now add domain-specific shapes for the end-user portal [Not covered here: the dynamic perspective]

What does it look like? class Person < ActiveTM::Base topic_map &quot;http://psi.example.com/&quot; psi &quot;http://psi.example.com/ontology/person&quot; name :firstname names :middlenames name :lastname occurrence :age , :datatype => &quot;xsd:integer&quot; has_one :country , &quot;inhabitant&quot; , &quot;country-inhabitant&quot; , :class => :Country def fullname &quot;#{ firstname } #{ lastname }&quot; end end

class Person < ActiveTM::Base

topic_map &quot;http://psi.example.com/&quot;

psi &quot;http://psi.example.com/ontology/person&quot;

name :firstname

names :middlenames

name :lastname

occurrence :age , :datatype => &quot;xsd:integer&quot;

has_one :country , &quot;inhabitant&quot; , &quot;country-inhabitant&quot; , :class => :Country

def fullname

&quot;#{ firstname } #{ lastname }&quot;

end

end

How is it used? p = Person.create( &quot;johndoe&quot; ) p.firstname = &quot;John&quot; p.add_middlename &quot;George&quot; p.lastname = &quot;Doe&quot; p.age = 25 p.save

p = Person.create( &quot;johndoe&quot; )

p.firstname = &quot;John&quot;

p.add_middlename &quot;George&quot;

p.lastname = &quot;Doe&quot;

p.age = 25

p.save

Can I use it? No. Not yet. Sorry.

No.

Not yet.

Sorry.
