Hey Gabriele, and rest of monetdb-developers, After a few weeks of inactivity I've resumed work on making datamapper work with MonetDB/XQuery. At the moment the dataobjects layer is working, it can construct a simple xquery and retrieve the results and map them to objects, as demonstrated here: http://pastie.org/781382
I am now working on implementing the other functionality, conditions, joins, creating, inserting and updating records. My primary goal is to use the MonetDB/XQuery as if it were a normal tables+rows-oriented database. (How to really exploit the advantages of XQuery/XML might be a whole new project.) This is what the XQuery monetdb adapter looks like now: http://github.com/d-snp/ruby-monetdb-xquery/blob/do/lib/monetdb_adapter.rb For comparison, this is what the standard DataObjectsAdapter looks like (outputting SQL queries): http://github.com/datamapper/dm-core/blob/master/lib/dm-core/adapters/data_objects_adapter.rb I have absolutely zero previous experience with XQuery so if you have any comments or suggestions, XQuery/XQUF snippets or patches they would be very welcome.
