Hi Darren,
thanks for the details.
As far as I understand you can find DASL support for
XPath and SQL in the JCR Server (not the simple server)
and it would be a matter of using the respective libs in
the simple server and provide for example a "basicsearch to jcr xpath"
conversion. Is that correct?
Shouldn't be too hard, should it?
If this is stalling your development maybe this could be
a good contribution ;)? Anyone interested ??
I've been looking at translating from Jackrabbit's internal query model
to DASL/basicsearch, and this is non-trivial, and definitively will not
be fully compliant.
When I'm done, I may be available to provide a summary. One major
problem I already encountered is that DASL basicsearch basically uses
scopes (with depth 0, 1, infinity) and conditions on query expressions.
Thus, a query such as
/*/foo
already can't be translated, because I can't tell DASL to restict the
path to resources whose last path segment is "foo". Another problem with
the basicsearch scopes is that a search at depth 1 includes things at
depth 0, thus query results will need to be filtered.
Best regards, Julian
