hi,
   thanks everyone for the feedback...i'm sorry i had
forgotten to add a readme file with installation
instructions when i first released it...i'm so spoilt
by windows+jcreator (java editor that i use) that i
had forgotten stuff like manually setting classpath,
running it from shell etc. anyway i've added a readme
now as part of RunningRDF.zip (thanks - Dan Brickley)

   Danny, the error you got seems to come when the
delimiters arent specified before pressing return (or
clicking the view records button)...i've got to work
on making the code more robust...also will definitely
look at the JSX toolkit you mentioned...seems ideal
for the job.

   the editor will be available as soon as i can get
it to stop doing weird things..:)

-aditya.
