I'm a similar boat related to graduating - but I'm happy to support a
volunteer or two by reviewing, answering questions and suggesting. Any
takers to do some small tasks to make elephant a little better or to
document the larger tasks that would make it lots better?
As for Daniel's request for m
A really good tutorial would be great; the test suite is probably the closest thing we have right now.
I absolutely have to focus on getting my business off the ground (which uses Elephant on top of
Postgres) before I volunteer for any more significant work.

I think there was a tutorial that included a simple design for a
persistent logging system and queries against it.
Should be in examples/index-tutorial.lisp.
There's a nice wiki example for UCW that could easily be adapted to show
off elephant - and a few of our users, including me, use elephant a
That's an excellent idea. I wasn't aware there's a blog for Elephant.
Is there one?
Thanks,
Daniel

i wonder if these sorts of design issues for elephant newbies might be

tutorial can be updated to reflect your more mature codebase and
mature approaches to designing applications? or a design faq?
just an idea,

All,
I think the long term goal is to make read/write policy something that
is integrated into a per-class policy with per-instance state. Robert,
have you forwarded that discussion we had about DCM to the list? If so
it should be in the archives from several months back. The short story

Not having looked at DCM yet, is it possible to just use the "persistence machinery" and DCM in a more seamless fashion? For example, if I declare a persistent CLOS class, can I hook that up to DCM and get the benefits of DCM and pers
Granded. Now, your original suggestion addressed the issue of using collections in slots and instead of collections of objects, simply to use collections of references to objects, which make sense and in a way is somewhat along the lines of what indexes do (from a general PoV).Not having looked at

Wow! What a great set of responses.
Thanks so much for the information.

Another way to get reasonable reporting efficiency for queries with
multiple constraints is to use cursors over secondary indices directly.
For your example I would create a CLOS class in Elephant instead of a
table. Each instance of this class is like a record in a table. To
link two records

Hi all,
I'm relatively new to OODB and in particular Elephant. I learn best
by working with applications, so normally, I would try to migrate
something I have done in a different application into the new
environment I'm learning.
For this exercise, I'd like to migrate an application I dev
