Continuing Research Profile: Co-Design ofInformation Systems

Structuring: Structures + static integrity constraints

Structures as object-relational structures

Static integrity constraints with enforcement policy and reasoning

Variable compilation of structures to DBMS

Functionality: Operations + dynamic integrity constraints

Operations generalized algebra for components and (sub-)schemata

Workflows on the basis of transaction models and on control models

BPMN formalised and well-founded

Dynamic integrity constraints defined in a temporal logic

Interactivity: Story space + media types

Story space defining the dialogues among actors

Media type suite based on generalized views

Distribution: Services through media types + exchange frames

supporting levels of abstraction including

Application domain layer providing information on the real issue

Business user layer used to reason on data and behavior of users

Conceptual layer providing full fledged specification

Implementation layer in full-fledged variety, tuning, etc.

Current Research Profile: ContentManagement Systems on Demand

Content management based on

content generation and injection depending on play-in sy-

stem

content play-out depending on stories, users and context

extracts of content describing the asset and providing meta-

information

Concepts associated with content specified on

abstraction layers of concept specification varying from topic

maps, through ontologies to logical theories

concepts maps in various granularity

Pragmatics of content depending on users and their

profile (skills, knowledge, ...)

portfolio (tasks, roles, rights, restrictions)

networked communities (collaboration, cooperation, commu-

nication, coordination, (ex)change)

Component theory based on

theory of streams describing the

functional systems with basic components and constructors

composition theory supporting construction through com-

ponents

Refinement and generation theory based on

abstract state machines

abstract state machine generators

Information system farms based on collaborating components

based on

integrated or cooperating views or databases
