Dear Markus,

please note that maps are not part of the official recommendation yet [1]. They have been proposed by Michael Kay (the author of Saxon) some time ago, and a variant of it will probably be included in XQuery 3.1.

However, we could think about adding BaseX-specific parsing rules to XQJ; this would be something Charles has to decide; just recently on this list, Andy has summarized the additional features of our XQuery parser [2].

All the best, Christian

Hello BaseX-community,

first of all, I really have to say that I really enjoy using BaseX and that I am really impressed by its active development and its ongoing improvement.

I am still a little unsure about the Query 3.0 support via the BaseX XQJ driver from net.xqj, though. According to the Changelog of the website ([1]), XQuery 3.0 via XQJ is now supported:

BaseX 7.3, 18.06.2012 [...]

• Charles Foster's latest XQJ Driver supports XQuery 3.0 and the Update and Full Text extensions: http://xqj.net/basex/

The README file of Charles Foster's driver also states that XQuery 3.0 is supported since driver version 1.1.0:

Version 1.1.0:

• Supports XQuery 3.0 + XQuery Update Facility + XQuery Full Text extensions.
• Various bug fixes.

However, take this minimal example using the simple map operator (query A):

BaseXXQDataSource dataSource = new BaseXXQDataSource(); dataSource.setServerName("localhost"); dataSource.setPort(1984);

    XQConnection con = dataSource.getConnection("dict_wsa", "lidell");

    con.createExpression().executeQuery( "(1 to 3) ! (. * 2))"); //query A

    con.createExpression().executeQuery( "let $m := map { 'one' := 1, 'two' := 2 }" +
                                         "return ($m('one')"); //query B

Executing it yield a syntax exception:

Exception in thread "main" javax.xml.xquery.XQException: XQJQS001 - Invalid XQuery syntax, syntax does not pass static validation. Root Cause: net.xqj.basex.bin.bn: Lexical error at line 1, column 11. Encountered: " " (32), after : "!" at XQ3Test.main(XQ3Test.java:21) at XQ3Test.main(XQ3Test.java:21)

For query B I also receive a syntax exception:

Exception in thread "main" javax.xml.xquery.XQException: XQJQS001 - Invalid XQuery syntax, syntax does not pass static validation. Root Cause: net.xqj.basex.bin.bj: Encountered " "{" "{ "" at line 1, column 15. Was expecting one of: "=" ... "order" ... "," ...

Is there another option I have to set to circumvent the 'static validation' or did I overlook anything else?

Regards and thanks in advance for any information or advice,

Markus Ackermann
