The top of the pyramid is the locator system the entry to this information the tip of the iceberg. The bottom of the pyramid is founded by the access to the data themselves. Our system is called CDS Catalogue of Data Sources. We see that there are some national metainformation systems around in Europe that have a very high level or degree of detail but still do not cover everything. This is why we concentrate on a common subset to all of them.
Harmonization is, therefore, an issue.
What we have achieved in this area is that member states are adopting the data model for the design of their national systems. You can imagine that each country has its own specialties and, like some people working with biodiversity, I imagine each country will have its own specific ideas. For example, some would like to have specific fields about plants or specific fields about beetles, and so on, just to describe the individuality of the source. However, there are some countries that stick very closely to what we are doing. They can easily change and adopt the software to their needs.
