Hi Jennie
thanks for your answer.
We have already visited the links you provided. But we still don't know how the import of the schema works (do we need to import it in the XML file or in the query? We tried both as mentioned on the monetdb-page, but did not make a difference in execution time), and if it has any effect. We also could not find any information on indexing and would be pleased to get information about that. On the "supported functions" page, a lot of for example dateTime functions are listed not to be supported. The schema type xs:dateTime is not listed, but seems not to be supported. Is this right? As we are planning to publicate the results, we want to be sure to get the best performance from MonetDB. Indeed currently the temporal types and functions aren't supported.

Hello Silvio,
First of all, thank you very much for trying MonetDB/XQuery!
To find (some) answers of your questions, I would like to refer you to the monetdb site: http://monetdb.cwi.nl Especially this page:
http://monetdb.cwi.nl/projects/monetdb/XQuery/Documentation/Supported-Functi...
As the name of the page suggests, there, you can find a list of supported XQuery features.
A list of XQuery built-in functions that have been / will be / won't be implemented can be found here:
http://monetdb.cwi.nl/projects/monetdb/XQuery/Documentation/XQuery-Functions...
Hoop this helps a bit.
Kind regards,
Jennie

Hi,
we're trying to benchmark different XML-DBs, one of them is MonetDB/Xquery. Two questions came up: 1) How is schema import done in MonetDB/XQuery? Does it affect execution time for queries? We imported it in the XML file and also in the query, but did not have any effect on execution time. Also, a lot of schema items such as xs:enumeration or xs:dateTime seem not to be supported. 2) Is indexing possible?
Regards, Silvio
