Ian Eslick made most of the code contributions to this release, which
features a very elegant method of indexing the slots of a persistent
class.
For developers, the internals of Elephant were also significantly
refactored
by Ian. Additionally, a layer of data management on top of Elephant
that
implements a Director-like pattern called Data Collection Management has
been added to the contrib directory.
In addition to personally thanking Ian, I would like to say that I
personally
think Elephant has grown into an extraordinarily useful project. Let
me
just review the major advantages of Elephant as a persistent object
store:
1) Extraordinarily convenient for the programmer,
2) An extensive test suite,
3) Tested on several major LISP implementations (ACL, SBCL, OpenMCL),
4) Ability to use multiple back-end data repositories and to migrate
whole
data stores seamlessly between those repositories,
5) Ability to BerkeleyDB, PostGres, SQLite 3, and probably other back-
end
databases,
6) Extremely convenient slot and functional indexing that can be
dynamically
changed.
The overall effect of these features together is that Elephant is very
flexible for
serious application development: you can change fundamental
implementation
decisions easily as your application evolves.
