Hi all,
Sory if you are not interested in half-baked home-grown query languages.
Monograph is an API for manipulating meta-data. It can represent
relational-db, object inheritance, ace-db style frames, DAML-OIL terms
and most other things using the same unified model. It is language
neutral (but this implementation is in Java). It is intended as a
sensible language for glueing different data-sources together (possibly
with very different query APIs) without the need to push some of the
query logic into client-side hand-written loops.
The exciting features possible in Monograph (but not fully implementated
by the current code-base):
* the ability to compare two database schemas to see if they overlap
* represent concepts like design paterns as first-class objects that are
generative models over code
* no distinction between meta-data and data - you can turn any
data-structure into the rules of a new language - indeed, single
data-values are just very restricted languages that only ave one
possible value - the data-value
* high-level optimization of execution paths that can potentialy take
into account the foibles of sub-class implementation details
I've just checked a new version of the core interfaces for Monograph
into sourceforge (project name monograph, CVS package monograph-live).
It is an almost complete re-write of the original code. It is very
un-polished, and there are loads of bits of core functinality that
aren't implemented yet (like validating types by schema). I will try to
check some documentation into the tree before Monday.
This is /very/ alpha code, but somebody out there may get the warm
fuzzies while reading through it.
all comments/flames/donations gratefully recieved,
Matthew
