Standards
Collaborations 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.

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.

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)
