OSNews, Generic OSes It's funny how trying to have a consistent system design makes you constantly jump from one area of the designed OS to another. I initially just tried to implement interrupt handling, and now I'm cleaning up the design of an RPC-based daemon model, which will be used to implement interrupt handlers, along with most other system services. Anyway, now that I get to something I'm personally satisfied with, I wanted to ask everyone who's interested to check that design and tell me if anything in it sounds like a bad idea to them in the short or long run. That's because this is a core part of this OS' design, and I'm really not interested in core design mistakes emerging in a few years if I can fix them now. Many thanks in advance.

That's pretty good, except:

- It's not esoteric, but widely used. Hence my example of HTML.

- I do not prefer XML. It has become a reflex for people to come up with that immediately, but like RPC, it's an implementation detail. Actually, I think XML is way too heavy.

- Specification sheets (such as DTDs) are not strictly necessary. This is also an implementation detail. A metadata specification is required if all the world needs to know the meaning of the data, but most interfaces are between parties that know each other and don't need to be understood by parties that have no preexisting knowledge of the interface.

- Therefore, there are no inherent drawbacks of difficult implementation. It can be as simple as you make it.
