Dear all, We provide you with a new and fresh version of BaseX, our open source XML framework, database system and XQuery 3.1 processor: https://basex.org/ Apart from our main focus (query rewritings and optimizations), we have added the following enhancements: XQUERY: MODULES, FEATURES - Archive Module, archive:write: stream large archives to file - SQL Module: support for more SQL types - Full-Text Module, ft:thesaurus: perform Thesaurus queries - Fulltext, fuzzy search: specify Levenshtein limit - UNROLLLIMIT option: control limit for unrolling loops XQUERY: JAVA BINDINGS - Java objects of unknown type are wrapped into function items - results of constructor calls are returned as function items - the standard package "java.lang." has become optional - array arguments can be specified with the middle dot notation - conversion can be controlled with the WRAPJAVA option - better support for XQuery arrays and maps WEB APPLICATIONS - RESTXQ: Server-Timing HTTP headers are attached to the response For a more comprehensive list of added and updated features, look into our documentation (docs.basex.org) and check out the GitHub issues (github.com/BaseXdb/basex/issues).

Hello Everyone, Not a big deal but can’t paste into the external variable dialog box. I have a script that has several external variables (urls) which are long so I paste them in the dialog box in the GUI (Basex-11.4). Anybody else experiencing this? Thanks for your time —Brian

Write files in parallel?
by Thompson, Timothy 17 Oct '24

17 Oct '24

Hello, Is it possible to call file:write-text-lines in parallel inside a fork-join operation? I have multiple databases that I would like to run a query over, in parallel, and write the results as JSON Lines to a file per database. When I try this, it doesn’t seem to parallelize. Thanks in advance, Tim -- Tim A.

How to recognize a byte-order-mark?
by Hans-Juergen Rennau 11 Oct '24

11 Oct '24

Dear BaseX people, there is a serializatioin parameter for adding a byte-order-mark when serializing. Such a document cannot be parsed using fn:doc() - error message: [FODC0002] "C:/projects/ofx-works/work/test-bom.xml" (Line 1): Content ist nicht zulässig in Prolog. This message is rather unspecific. My question: is there a way how to determine if a byte-order-mark is used in a given file? Kind regards,Hans-Jürgen

Hi Navel, > BaseX Xquery CSV module is for dealing with CSV files which we don't have. With this module, you can serialize XML data as CSV (and parse CSV back to XML). But that’s certainly just one way to do it. Hi Owen, > However, I wonder how BaseX might deal with more than a million records. Feel free to get back to us once you encounter any limits.

Setting multiple CSV EXPORTER options is not documented on docs.basex.org
by Omar Siam 02 Oct '24

Hi, I just tried after some time to script a CSV export with a BXS file. I forgot how to set multiple options for the csv serialization. In the end this worked: <set option="EXPORTER">method=csv,csv=header=true,,lax=false,,quotes=true</set> I can not find it on docs.basex.org. Perhaps this should be added and explained.
