Reference Architecture

From Geostandards

At the moment the NGII Reference Architecture consists of three public documents:

1. Gideon (VROM, 2008)
2. Framework van standaarden (Geonovum, 2007)
3. INSPIRE documents (i.h.b. Smits, 2002)

The paragraph on geo-information in NORA 2.0 (ICTU, 2007) is not included because this is a subset of the Framework of Standards (Geonovum, 2008).

This present setting of the three reference documents mentioned above will change. In all events, a katern Geo will appear together with NORA 3.0 so the facet Geo will be recorded within the reference architecture of the e-government. In addition, it is not out of the question to anticipate that global maps, such as those developed for the e-government, could become tailored for geo-information access so that the role of geo-information within the e-government could be recorded.

As well as the reference architecture geo-information for the e-government, other reference documents will have to be drawn up too. Consider reference documents for:

• Concepts of the NGII
• Geographic services
• Geographical processing systems
• Etc.

In order to create a clear picture of the reference architecture, the NGII will be made into a cohesive body. This can be done in several ways:

1. Via a position paper describing the relationship between the various reference documents that are mentioned above and containing instructions about how the documents should be dealt with in practice;
2. Via a reference architecture document for GII held within the government, in which the entire description of the reference architecture is included. An example of this can be found in GDI-DE (2007);
3. Via a reference architecture document for geo-infomation, in which the entire description of reference architecture is included. An example can be found in CIO Council (2009).

The Project Start Architecture (PSA) is a supporting tool of NGII reference architecture used to execute modifications in the provision of geo-information within the context of the NGII. The PSA gives directions towards finding the solution; however, it does not offer the solution itself. The solution is part of the GII project. The PSA offers the framework and the context by way of principles, policy and standards.

The figure below indicates the PSA documents with the best practises which may be helpful for getting a quick and clear start with the GII project. These best practises still have to be produced.
