Newbie questions

Hi, I'm a BaseX newbie struggling with the basic "Hello world" type stuff and struggling to find documentation to answer my questions... 1. Where is the main body of BaseX documentation? 2. I can't see a service on my machine called "BaseX". What's doing the server-side work? I'm using Windows 7. 3. The PHP example does this... $cmd = "xquery 1 to 10" which it sends to the sever and gets a result. As far as I know that's not a normal valid xquery command yet it returns a result ok. I would expect $cmd = "1 to 10" to work ok but not $cmd = "xquery 1 to 10". Do all queries to BaseX using the PHP API have to start with the string "xquery ", followed by the xquery itself? 4. Where's the documentation for the PHP API so I can find the answer to the above question myself? 5. Is there a web-based forum for BaseX? Thanks Nigel

Hallo Markus, im aktuellen DeepFS-Code kenne ich mich nicht bis ins Detail aus. Ich leite Deine Mail mal an Bastian L. und Alex weiter; vielleicht haben sie ein paar Ideen?

Hello, I would like to do some development with basex. I downloaded the project and am looking for a book or documentation to print out. What sort of references do you suggest. I am looking for more documentation than I found on the main page documentation from your website. Thanks, Evan

Small project based on BaseX
by iorulezz＠gmail.com 27 Jun '10

27 Jun '10

Hello all, we are two master students at the university of Utrecht. We have a DB Architecture class that includes a small project (15%*7.5 ECTS= 1.125 ECTS). So, BaseX looks like a good chance to work on such a project. Our idea so far is based on some benchmarking experiments and small summary on how it works (maybe its relation with Monet) including any experiments we run (5-6 pages). Do you have anything better for us to do (maybe something you can get advantage of yourselves) or any guidelines/hints/whatever? Take into account that out time limit is approximately a week (full-time) and that we cannot do more work that what deserves 2.25ECTS for the 2 of us. I look forward to an answer (so we can decide and start working -the deadline is 9/7-. Best regards, Antonis

ADMIN permission needed for basex:read(...)
by Sandra Maria Silcot 27 Jun '10

27 Jun '10

Fellow basex users, Test case: (as 'admin' user:) run file1.xq, containing: let $test := basex:read('/tmp/222.readme') return <test>{$test}</test> Returns, as expected: <test>readme from basex </test> But when run as any other user WITHOUT admin privilige (from the log): RUN /tmp/222 Error: ADMIN permission needed. 7.75 ms Behaviour is the same if the file is copied to be inside the basex home directory e.g. basex:read('222.readme'). I would like to be able to read files in basex queries as a non-admin user. But perhaps the admin restriction on this behaviour is by design? Cheers, Sandra
