Re: [DISCUSS] DataContext as a (web) Service

[Kasper Sørensen <i....@gmail.com>]

Although this didn't seem to catch the immediate attention of anyone, I
anyways need a good example use-case for my Apache: Big Data talk so I made
a prototype of a system like this. If anyone's interested the code can be
found on my github account [1] and later on I might suggest it for
inclusion in MetaModel if people seem to like it :)

Henry it almost sounds like you have some idea for that in mind? :-) I
didn't really give it much thought tbh.

Thanks for sharing, Kasper.

If it was going to be delivered as distributed system, how can it
provide discoverability to the services?

Glad to see the interested faces :) Maybe you can check out the code and
try it out. Would love some feedback and maybe with that we can think of
including it (or something like it) in a new module under MetaModel itself.
