Hi Sanjoy,
Sorry for the late reply; I had to dig around in grph-inc.lua, and I'm
a bit rusty at source-diving.
Yep, that’s a problem all right. A bug, even: when you put `simple.1`
in the same directory as the `.tex` file, it is correctly identified
as MetaPost; when you put the exact same file in a subdirectory like
`./fig`, you get the problem you describe. No clue why.
Until Hans fixes this, you can force ConTeXt to treat a file as
MetaPost, JPEG, etc. by passing the `method=` paramater to
`\externalfigure`. For MetaPost, write `method=mps`; I don’t know why
the MetaPost code is not `mp`. (Perhaps that could be made a synonym?)
Complete example below. I hope this workaround helps? Good luck with your work!
you can test with this (line 767 in grph-inc):

             askedformat = format -- new per 2013-08-05
         elseif trace_figures then
             report_inclusion("unknown format %a",askedformat)
         end
...
Cheers,
Sietse
