Error report in baseX-dev
by Bowers, Jack 03 Aug '16

03 Aug '16

Hi, I'm trying to delete some files that I just added to my db To give context, I originally added them via Oxygen data source explorer baseXdev, but I am trying to delete them in the dba https://basex-dev.eos.arz.oeaw.ac.at/dba/database?name=dboe-xml and the error 500 message below is what occurs. The uploading process originally stopped and gave an error message and listed about 4 files that would not be included in upload but the rest appeared but now nothing else can be added or deleted.

users.xml change outside basex
by Maximilian Gärber 02 Aug '16

02 Aug '16

Hi, it seems all of users.xml will be rewritten on changes. I just tried to add a <groups> element next to <users>. Any way to preserve changes in the users.xml ? Maybe allow for a <custom> section or similar? By the way: what was the reason users.xml is not stored as a basex database but on the file system? Regards, Max

db:optimize questions
by Baysdon, Joseph 02 Aug '16

02 Aug '16

I a new baseX user and I have a few questions regarding the db:optimize command. Does 'optimize all' perform all available optimizations or are there other parameters (indexing or full-text as mentioned at http://docs.basex.org/wiki/Database_Module#db:optimize) to supply? Is read/write possible to a database undergoing optimization? I’m guessing no because I get an error (“Database ‘foo’ is currently opened by another process”) whenever another connection to the database is open. On what size or content of databases does optimization have a significant impact? Currently on a 400Mb database, I don't see any performance benefits after optimization. (Note: all of my performance testing is using a simple db:list command.) Thanks in advance for any assistance you can provide. Joe

Non-Admin user and db:system()//repopath
by Maximilian Gärber 01 Aug '16

01 Aug '16

Hi, this returns nothing (as non-admin), but I noticed you can still list any folders above. In my case the empty string left to having a path with a single slash '/' which translated to the root of the drive that basex was installed. I got the complete contents of the drive with our query [1]. The way it is right now, I see no reason why db:system()//repopath returns nothing. Regards, Max Happened with BaseX: 8.4.4 [1] https://github.com/axxepta/project-argon/blob/develop/src/main/resources/ap…

NPE in Basex8.4.4

Re: [basex-talk] Validating with XML schema
by Christian Grün 31 Jul '16

31 Jul '16

Hi Chahd (cc to the list), > Can I do it with the Rest service? Yes you can [1]: http://localhost:8984/rest/MyFirstBase/text.xml?query=validate:xsd(., db:open('MyFirstBase/text.xml')) I agree this doesn’t look very straightforward. If you are interested in spending some more time with XQuery, you could use RESTXQ [2] to provide more intuitive URLs. An example: Your URI: http://localhost:8984/restxq/validate/text.xml?schema=validate:xsd Your server-side RESTXQ code (see the documentation and the example in the zip/exe distributions for more details): declare %rest:path('/validate/{$doc}') %rest:query-param('schema', '{$schema}') function local:validate($doc, $schema) { let $db := 'MyFirstBase' return validate:xsd(db:open($db, $doc), db:open($db, $schema)) }; Christian [1] http://docs.basex.org/wiki/REST#GET_Method [2] http://docs.basex.org/wiki/RESTXQ On Sat, Jul 30, 2016 at 11:41 PM, Chahd Chahd <chahd.chahddd(a)gmail.com> wrote: > > 2016-07-30 22:24 GMT+02:00 Christian Grün <christian.gruen(a)gmail.com>: >> >> Hi Chahd, >> >> > I am using the web application of BaseX.

Path of a resource
by Chahd Chahd 31 Jul '16

31 Jul '16

Hi, I am using the Database Administration interface. I created a base named "MyFirstBase" and I add 2 resources (test.xml and test.xsd). How can I write the paths of the resources properly in a query? I tried: validate:xsd('test.xml', 'test.xsd') but I have a *[FODC0002] Resource 'test.xml' does not exist.* *Thank you*
