Vision

Germany-Online

National e-government strategy of all levels

Goal: an integrated e-government system

Consists of two infrastructure and four priority projects

Germany-Online Standardization (GOS)

Managed by the Federal Ministry of the Interior and the federal state of Bremen

Goal: support and coordinate the development and provision of standards for electronic data exchange

GOS conceptmap

Concepts are used here as a notation of (practical) knowledge based on the aspects of abstraction and guiding interest.

Abstraction is defined as a subject-dependend grasping of intersubjectiv and timestable relations in the problem-solution-space

GOS Concepts: 17

Relations: > 40

Context

Concepts

GOS framework

german: XÖV-Framework

need: interoperabilty of semantic standards within the public administration

solution: rule base and prescribed project development model

approach: experience (good practices) of successful projects, international guidance (UN/CEFACT) and V-Model XT

[PRO] consistently developed standards – existence of a binding rule base

[CONTRA] rules are difficult to scale

references: GOS CC, monitoring, GOS projects, GOS coordination, GOS adjustment authority

Experience

Outcomes/Findings

Context

Concepts

GOS projects

german: XÖV-Projekte

need: comparability of generation, quality and reuse of fruits

solution: GOS-concepts and the quality characteristic „GOS conformity“

approach: use of GOS-framework, a question form and research

[PRO] orientation for the projects – unified overview of existing projects

[CONTRA] weak incentive structure due to legal formulation

references: GOS CC, coaching, XRepository, GOS coordination, GOS adjustment authority, GOS framework, XGenerator, CC validation, F&P support

Experience

Outcomes/Findings

Vision


Context

Concepts

GOS core components

german: XÖV-Kernkomponenten

need: german information atoms due to legal parameter

solution: orientation at CCL and CCTS

approach: derivation of GOS CC is based on CCTS - but german attribute names

[PRO] unified information entities – consideration of legal constraints

[CONTRA] mapping to UN CCs needed for international interoperability

references: GOS framework, GOS projects, GOS toolchain, XMap, workgroup data conference, XExample, CC validation, CCTS, GOS adjustment authority

Experience

Vision


Context

Concepts

GOS coordination

german: XÖV-Koordination

need: monitoring and coaching of GOS projects / development of GOS concepts

solution: establishment of a central unit

approach: development and appliance of methodologies

[PRO] central knowledge base – essential aspect of GOS

[CONTRA] complex and time-consuming

references: GOS projects, coaching, monitoring, GOS framework, GOS guideline, workgroup data conference, XMap, XExample, XGenerator, CC validation, F&P support, GOS adjustment authority

Experience

Context

Concepts

GOS toolchain

german: XÖV-Werkzeugkette

need: comparability of functional models and technical artefacts

solution: automatic rule examination with subsequent generation of artefacts

approach: UML modeling -> Transformation -> Generation of XML-schema and documentation

[PRO] separation of model and artefacts – MDA-approach

[CONTRA] XMI as a barrier for UML-Modeler – quasi-proprietary chain

references: XExample, GOS CC, UML profiles, GOS projects, GOS coordination, CC validation

Experience

Outcomes/Findings

Vision


Context

Concepts

XRepository

german: XRepository

need: central place for standards and CCs

solution: semantic repository

approach: multistage quality process

[PRO] overview of existing standards – at different stages, different qualities

[CONTRA] no automatic download of all CCs for an UML-modeling-tool

references: GOS projects, GOS framework, GOS CC

Concepts

XMap

german: XÖV-Landkarte

need: semi-automated generation of standards/datastructures

solution: question relevant actors

approach: online-survey for collecting communication interfaces

[PRO] it works – identification of new datastructures

[CONTRA] granularity of datastructures not adequate – timeconsuming

references: GOS CC, GOS coordination, workgroup data conference

The usage and combination of concepts bring insights at different levels:

Adaption of the GOS framework

Work of the data conference

Diffusion of knowledge

Data modeling process / toolchain

Development fo the XMap

Experience

Adaption of the GOS framework / monitoring

GOS framework contains 30 rules which split-up in over 70 subrules hardly any project achieved the predicate „GOS conformance“ monitoring/evaluation/coaching of projects difficult and time-consuming

Actual: collecting/evaluating different views for a new GOS framework „light“Outcomes/Findings

Concepts


Experience

Work of the data conference

Development of a „german“ core components library in version 1.0 beta was a good first approach

Through the validation of CC it arises, that

a reduction of complexity at CC level is nessesary (less ASCCs)

no agreement for a few CCs (e.g. NameNaturalPerson or Housenumber)

modifications of naming, description, multiplicity and data types are needed

not all projects use CCs in the required way

Experience

Diffusion of knowledge

GOS concepts were transported through different communication channels

Owe to the inherent complexity, the knowledge diffussion process to the GOS projects was slow and partly fragmented

Direct consequences:

GOS guideline helps to build the „big picture“

XExample shows how to build a semantic standard

GOS framework „light“

XMap reached a broader audience

Concepts


Experience

Data modeling process / toolchain

The way from the UML-model to the XSD & Dokumentation is achieved via a three-step-toolchain

step 1) modeling with the UML-modeler MagicDraw -> export as EMF-XMI

step 2) transformation from XMI to XSD/docbook with the XGenerator

step 3) building of a pdf document with Framemaker or Oxygen

Step 1) requires high expert knowledge

Only step 2) is complete OSS

Big projects require coaching

Changing XMI format restrict UML-modeler

Development of the XMap

In a first step 44 municipal IT manufacturers provide 138 communication interfaces

At the second step we collect 230 interfaces from federal-state agencies

It is planed to survey in the last step the federal ministries

From the collected data we derivate

an overview of the actual interface „landscape“ of germany

priorty of GOS projects

new and existing GOS CCs

Outcomes

Over 20 GOS projects

Outcomes/Findings

Findings

Publics/Politics

Legal foundation of standards is essential

Supervision of GOS-projects matters

UMM

De facto: data-oriented standardization -

but: the rising UMM-tide is flowing in

A non-opensource modeling-enviroment is hardly acceptable

Needs

Need for a method of identifying and evaluation of CCs

Need for a user-friendly (open-source) modeling environment

Need for a international multilingual-CC-mapping platform

UMM 2010
