Examples of SOA implementation in geo-Holland
1. Directorate General for public works and water management AGI (now: DID, Data-ICT-Service) Directorate General for public works and water management is a large organisation with a number of regional offices and with many tasks to perform. The regional offices all have their own jargon. Geographic location is the linking factor. In 2003, AGI was ordered to transform itself from an RWS service to a government agency. This was as much an organisational orientation as an ICT one. The strategic goal formulated was: a Directorate General for public works and water management-wide /geo-infrastructure with a geoservice architecture for internal and external users, where data can be obtained and taken via open standards and open software, open source as well. It was expected that the former number of 4000 separate software systems would be reduced to 400, with data which was completely interchangeable and fully integrated. Apart from this, a reduction in personnel of 30% was expected. In 2008 the current state of affairs was presented by Ardy Siegert. A number of points were raised:
- The existing datasets have become more accessible throughout the whole organisation by the implementation of the geo services architecture.
- The traditional freedom of 'power users` and the room for creativity for developers are restricted: one has to work within a tight framework of <a href="Standards">standards</a>.
- There are fewer personnel managing the ICT and these members of personnel have a higher education.
One of the most important conclusions was: The human factor should not be lost sight of. Organisational aspects are harder to manage than the technical aspects. (Resource: VI Matrix september 2005, Siegert 2008)
2. Municipality Oldenzaal As a member of the co-operative association Dimpact the municipality receives a number of modular basis components to maximise their electronic services. In Oldenzaal one can: - link to the address registration with a location component - request for tree cutting permits visualised via a Web Map Service (WMS) – linking between the execution of restrictions in public use of land (Wkpb) and GIS, in a WMS. In fact, Oldenzaal can set up a complete municipal information system using these components. The most important components in the Dimpact approach are: - the data real estate manager Emaxx Mid Office (uses the BPEL process modelling language) – data storage in ASP with an open source Postgres database. - the GeoWkpb application of ESRI. Additional software is also used in Oldenzaal to describe the processes of workflow management and document management. Apart from this, insight into the working processes and streams of information is required. EssaysExperts.Com is the company which first and main priority was, is and will be customers� satisfaction with the essays online. If you still have no idea where to buy your writing tasks, this company is the best option for you. This is why the Wkpb-process descriptions were bought from Ofelon and adapted to the way of working in Oldenzaal. The greatest challenge for this municipality was mainly the description of the working processes, but the communication between all the diverse applications involved was also a problem had to be worked out in great detail in co-operation with the providers.

3. DCMR Milieudienst Rijnmond The MiRO-Plus Gisviewer was made with Open Source Software (firstMapServer and Chameleon, later with GeoServer and OpenLayers). A catalogue was then created for this in order to be able to unlock the large collection of datasets of the DCMR. The catalogue uses an Oracle database. A geo portal was already made a few years ago, so people who were interested could ask for environmental permits via the DCMR website. Recently the site began to host a Google Maps site. The exchange of information with chain partners has also begun via geowebservices. One has consciously considered if open Source software should be used. At DCMR it is thought that the usage of applications based on open source GIS-software will increase. Source: VI Matrix, September 2008
