Cool!

This would map to state "known"

This would map to the state "unknown"

This to the state "ignored".

This to the state "added".

This could map to the state(s) rename_source, rename_target and the 
changes types "content" and "attrs", so an OR of all these states would 
be sufficient.

No real equivalent here, you could handle the state "invalid" with this, 
which pops up f.e. if a node is recorded as file (but missing) and there 
exists an unknown directory with the same path (and vice versa). The 
resolution here is to rmdir the directory because you can't call 
anything on an item like this (i.e. revert will fail unless you remove 
the directory).

There is no such state yet available in inventory since mtn has no 
concept of workspace conflicts yet.

This is reflected by the combined states "dropped" and "unknown".

> missing: this file is removed in the workdir , but still exists in the metadata

This is the state "missing".

Yeah, I see no equivalent here either...

Cannot be mapped either, but even an empty file has a content hash and 
this has a fixed ID (da39a3ee5e6b4b0d3255bfef95601890afd80709) - so you 
might just compare that ID with the one inventory gives you and set the 
"empty" flag likewise.

> hidden: this is a hidden file (its used on some vc's, it might go away)

This should be "ignored", shouldn't it?

I think this is plausible so far. I know some other vcs don't 
distinguish between tree / content / attribute changes, so the 
"modified" mode is a bit overloaded for monotone now.
