- Geo-information (data)
- Within the framework of legislation operational
partnerships must be established. - MoUs express intentions
- Setting the area(s) of interest
- MoUs must cover all areas of interest
- Collaboration must cover agreements upon sharing
information over services and registries

StandardsCollaborations are policy statements
(position paper). MoUs do not say anything about
the work items.Standards are a kind of
agreement on 'What are we going to work on? How
do we define our activities?'Standards are
general. Therefore they can be used for several
concrete projects.Specifications are concrete,
and are valid for one project.

32ModelsModels describe, how given standards have
to be used for a certain project. Models bridge
the gap between standards and specifications.Val

Specifications
- Specifications define what should be done in a
given, concrete project according to a certain
standard - Specifications contain rules for action
(behavior) for a given project - Specifications define the content (both system
and information) for at given project

- Geo-information (data)
Services Services are the concrete, practical
set-up of the passive components (no. 1 to 5).
All passive components no. 1 to 5 can all be
carried out on a piece of paper nothing
practical has happened until then. Services
establish the technology, i.e. software,
hardware, user-interfaces etc.

- Geo-information (data)
Metadata and information- Metadata and
information are the 'fuel' for the machinery (the
services) once these have been created.
- Metadata and information are not
technology!- Metadata and information are the
actual, practical, concrete result of a given
production, which has been carried out in
accordance with the characteristics of the
services, with the specifications, with the
models, with the standards, with the MoUs and in
accordance with the legislation.

Does it make sense to say I need a building of
188 m2
Answer What sort of building do you need? (and
the answer to that question depends entirely on
the usage)
