[eclipse-incubator-e4-dev] [resources] EFS, iFS, Monitoring, encodings a

["Oberhuber, Martin" <Martin.Oberhuber@xxxxxxxxxxxxx>]

Sounds good!

I think that EFS should cover exactly those aspects of
file systems, which we need in our frameworks / generic
algorithms - nothing more.

In terms of Monitoring, one thing to consider is that the
monitor and the file system may actually be two separate
providers. Consider the SSH remote file system that we
have in RSE -- it doesn't provide monitoring capabilities.
But some extender could go and write an add-on (using
a separate channel to the remote) to provide a refresh
monitor. 

I don't think that this use-case is extremely important, 
but I'd like to understand what's the benefit of moving 
the RefreshMonitor into EFS instead of keeping it separate.

I agree that the Adapter pattern may be a nice way to
provide access to add-ons like access to ACL's, ownership 
info, etc.

That being said, and while you're looking at iFS ... I've been
told that there exist file systems where the encoding of 
elements is specified by the file system. Others (HTTP, 
WebDAV) provide a Content Type right from the file system.

I'm wondering if we'd want to support that in e4, or keep using
a totally separate (non-integrated) mechanism for encodings
and content types?
