Master Vs Reference Data

Master Data – the fixed information needed to perform business operations. Master data carries data relevant to a business entity (such as customers, vendors, inventory, etc.) that is valid over a period of time.

Reference Data – lists of information that are used to restrict the contents of other types of data; for example, a list of valid country codes that is used as a lookup table to restrict entries for the customer “country of origin” field…

MODAF Viewpoints

Source: Introduction to MODAF v1.2 (PDF)

The MODAF (Ministry Of Defense Architectural Framework) defines several views for Enterprise Architecture:

The architectural views are categorised into viewpoints:

Strategic (StV) – defining the boundaries of the enterprise and its vision, goals and capabilities

Services (SOV) – specifying services, the interfaces they present and how they may interact (but not how they are implemented)

Logical (OV) – specifying how the enterprise is required to be logically structured and how it functions

Physical (SV) – specifying how organisational and system resources interact in order to deliver capabilities and services(OV).

Programmatic (AcV) – supporting information about when solutions are to be delivered and by whom

– Standards (TV) – listing the standards which apply to the architecture

All Views (AV) – metadata and standard terminology 


Here is the DIGB-SA study Archimate model that has been built with Archi 2.6:

If you don’t want to install Archi, you can have a look at the model here:

I have received the authorization from my clients to publish it in order to:

  • Encourage the modeling practice and reuse among public libraries
  • Share with the Archimate community as an example

The model reuse is subject to the following  restriction:


This model is published for reuse by public libraries. It can’t be marketed, sold or resold.

This model has been developed by Jean-François Declercq in the context of the DIGITAL LIBRARY SYSTEM ARCHITECTURE study by ordered by:
– Bibnet vzw
– Vereniging van de Vlaamse Provincies
– Vlaamse Gemeenschapscommissie van het Brussels Hoofdstedelijk Gewest


PS: A Dutch version of this model is available at Bibnet (…

Study Published: the system architecture of the digital public library

26 march 2014

The reports of  the study on the current and future system architecture of the  digital library have been recently published.

The term “digital library” is here used as a collective name for all of a library’s products, processes and services that are digital and/or automated.

The study summary lists the future work zones for the  Flemish Public libraries:

  1. Business intelligence (BI)
  2. IT maturity
  3. Web presentation
  4. Identity and Access Management (IAM)
  5. Digital Collections
  6. Collection Management and cataloguing
  7. Architecture consolidation (SOA)

The summary is available in French, Dutch and English:

The complete study has three main chapters :

  • Current system architecture of Flemish public libraries (AS-IS)
  • Evolution of the Flemish public libraries’ System architecture (change requirements)
  • The Future system architecture of Flemish public libraries (TO-BE)

The future system architecture is in fact a generic future-proof ICT blueprint for a public library. The blueprint is a set of business services, business processes, Applications, SOA Services and technological elements documented in the Archimate notation.

Business Services Overview

The complete study is available

I would like to thank the colleagues who worked with me on this study:

  • François Vermaut (IT Strategy, BPM, SOA, ITIL…)
  • Rosemie Callewaert (Public Library field expertise, User Experience, BIBFRAME, FRBR…)
  • Simon Kroeger (Proof reading english text)
  • Veerle Vanlooy (Vertalingen Vanlooy)

I also would like to thank the steering commitee (Bart Beuten, Jan BraekmanPatrick Vanhoucke ,Stefaan Froyman), all the workshop and participants. Their input has been key. I would like also to thank Alexandre Lemaire who helped me to compare the Flemish situation with the situation of the Fédération Wallonie-Bruxelles.…

[Updated] Mobile App Development : my experience with Zend Studio

If you are looking for Mobile Apps development, have a look at Zend Studio.

This monday 28-JAN-2014, we managed to install Zend Studio and develop a web mobile app easilly.

We found ZendStudio to be much easier to setup and use than the Sencha  suite of tools (including Sencha Touch).

Zend Studio integrates Cordova and packages it easily to help you access the native functions of Windows, iOS and Android devices.

The nice thing with Zend is that is it allows you ton integrate plain html files and other javascripts in your project resulting in great flexibility in the app design.

The only glitch we had was a problem with the Android emulator which was not willing to start. I downloaded Bluestacks to test our application.


Update 17-MAR-2014

At the end of the day, we had several problems . Mainly for compiling Android apps with Cordova: the app couldn’t find the classes. Also Cordova was very slow for geolocation. So it looks good at first sight but there is still some work for the Zend Studio team.…
