2. I was not aware that .pie is specific only to OWLIM, therefore my

is that in what format are predefined rulesets in Sesame Workbench stores?
Main idea was to add custom ruleset in workbench, I agree that editing
would not make much sense.
No worries. There is no standard for Sesame, it doesn't have a general
rule engine in any language to replace the rules used - this is one of
the advantages of OWLIM.
3. I understand that I can't change ruleset just like that... ,my
point is that our application is still in developement and therefore I
change ruleset from time to time (but I don't expect it is
immediatedly applied to repository). I thought OWLIM compiles rules
during creating new repository. Therefore I didn't expect changes in
.pie aris e immediatedly used.
Our common scenario is that :
a. There is working repository with working ruleset.
b. I would like to add some rules (but without recomputing them and
without having additional rules file)
c. If set of new rules will be final, I can drop the working
repository and recreate it with new rules.
So new rules in the file at which the repository points are applied,
after these are compiled (each start up), as new data is added. Note
that this is different from re-inferring over the existing data (which
is also possible). In order words the ruleset is not fixed for the
lifetime of the repository.
It happened to me few times that I changed .pie file and then Tomcat
restart came and I couldn't delete repository nor to create the same
one with the new rules. Therefore I had to revert .pie file, delete
repository and then I can again change .pie and create new repository.
If it has some technical explanation I would accept it and try to
avoid the same situations. It just happened to me few times and
therefore I asked whether it is possible to change it.
For the reason above (that the rules executed on new data is added are
changed according to the file contents) you should not edit the file
(rather a copy) unless you're sure those are the rules you want executed.

2. Since PIE is an OWLIM-specific rule format, it would not make sense
to add this to the Sesame Workbench. The OWLIM Workbench already has
an option to upload a custom ruleset.
While editing is something that could be considered for the OWLIM
Workbench, it's probably a feature that's used by only a small
proportion of users, for a very small proportion of their time, that
other features would be likely to be prioritised.
3. a) it's worth considering that rules are internalised, but this
would make it more difficult to change the ruleset used in an existing
repository (via SPARQL). Would it not just be easier, when you're
using a custom ruleset, to create a separate ruleset file for each
repository and a separate one to make edits? In the case of deletion I
do agree (on the Sesame list) that having to initialise the repository
before deleting it is a pain.
