Hi Bernard

I have just made post the should cover part of your question. As
mentioned in this post the kernel component is central to the
architecture of an openEHR system as it brings the two models
together. For persistence many solutions would be possible. Like XML
(that what Ocean Informatics uses in their EhrBank product) or an
object-relational-mapping solution. But it should be noted that just
instances of the reference model need to be persisted including
references to the archetypes used to create the instances. The
archetypes can be retrieved again separately when the persisted data
is loaded through the kernel.

For Java kernel code have a look at

Here one more link to a nice overview written up by Thomas about
persistence possibilities and techniques. Most of you will already
know this:
