Can I ask you what this error actually indicates and what caused this? Our data is under contract so it's difficult to provide it directly.

GET for an application/query does not evaluate the query first
by Ludovic Kuty 22 Apr '12

22 Apr '12

Hi, I used an old version of BaseX (7.0 I think) and made HTTP GET requests to application/xquery ressources in the database which evaluated them before returning the result of the evaluation. That way I could used predefined XQuery queries stored in the database. The following sentence is written in the documentation at http://docs.basex.org/wiki/REST#Operations : "If a resource with content type application/xquery is addressed, it will be evaluated first, and the result will be returned." But it no more the case in 7.2 and instead I get the query verbatim, not the result of the evaluation. Indeed, Googling around I even found a bug correction made by Christian Grün ( https://github.com/BaseXdb/basex-api/blob/146d594931abe0143766203a329d8f682… ) to an old version of the code. We can see at lines 76 to 82 that an application/xquery ressource is evaluated first: if(type.equals(MimeTypes.APP_XQUERY)) { // execute raw file as query final ArrayOutput ao = new ArrayOutput(); session.setOutputStream(ao); session.execute(new Retrieve(ctx.dbpath())); query(ao.toString(), ctx); } Thus, I tried to find the same sort of code in the actual 7.2 version but could not. So I am wondering if this is a wanted omission, and thus the documentation is out of sync, or if it is an unwanted omission and needs to be corrected. The code I checked is at https://github.com/BaseXdb/basex-api/blob/master/src/main/java/org/basex/ht… The workaround I used is to put my queries as files in the HTTPPATH directory found in the .basex file. TIA for any clarification on that matter, Ludovic Kuty

JSON/XML mapping
by Hans-Juergen Rennau 20 Apr '12

20 Apr '12

Hello, I have a couple of questions concerning the XML/JSON mapping, described in the documentation JSON Module/JSON Functions. 1) The text says: "As arrays have no names, <value/> is used as element name." But I suppose it should be "array members", rather than "arrays", as an array may of course be associated with a name as any other JSON item. Correct? 2) So are there all in all 6 reserved attributes names (type, numbers, booleans, nulls, objects, arrays) and 2 reserved element names (json, value)? Or have I forgotten some names? Thank you very much. Hans-Juergen

maven repo
by Christophe Doniat 19 Apr '12

19 Apr '12

Hello, I would like to make a tryout of your techstuff. So I added your maven repo in my nexus server as proxy (http://files.basex.org/maven/). But when I wanted to browse the repo index I didn't see any version that I can see through a browser way. Therefore I pointed out that the archetype-catalog.xml file (in the root of your repo) is empty. Would you mind to generate this file and the link could be done? Command: mvn archetype:crawl, see there for more information: http://www.sonatype.com/books/mvnref-book/reference/archetype-sect-publishi… Thanks in advance, Regards, C. Doniat
