Filesystem Storage

Question

Hi there,
I'm currently evaluating Kodo 3.2.3 and couldn't find a satisfying solution
to the following problem:
Due to customer requirements we need to provide a store which makes use only
of files and directories of the filsystem. Performance issuses must not be
taken into account. Each object should be a single file. For searching there
should be one or more index files. The index files must not contain any data
which is not part of an object. It should be multi user aware using
something like lockfiles.
Did anyone implement something like that yet?
Will it be possible to implement such a store with a moderate effort based
on the kodo framework?

Will it be possible to implement such a store with a moderate effort based
on the kodo framework?First, I'd try to convince the client to use a file-bsed SQL database like
Hypersonic SQL or JDatastore, both of which Kodo supports.
But Kodo does allow for creating custom back-ends. In fact, we include a demo
of a custom Kodo store that reads and writes XML files. You can use this sample
to build your own store. See src/kodo/xmlstore/ for the implementation code,
and samples/xmlstore for some sample client code using the XML store.
