automatic encoding
by Philippe Pons 06 May '21

06 May '21

Hi, This may be more of an xquery question than a BaseX question, but I'm trying to ask it here anyway. I can of course remove it if necessary. However, I have an XML document with a sequence of paragraphs and a CSV spreadsheet (examples 1 and 2 below). The csv gives a list of terms in the first column (present in the XML), and the name of the index in which we want to integrate this term in the second. I use BaseX and XQuery a lot, and I'm looking for a way to automatically encode the terms in the TEI file without success so far. I've tried to rely on the ft:mark function to achieve this, but it doesn't completely fit my need. Maybe you could give me some advice to get the result I'm looking for (example 3)? With kind regards, Philippe Exemple 1, XML : <div> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc quis nisl ultrices, viverra erat id, volutpat magna. Mauris cursus tellus non nisi commodo faucibus. Pellentesque condimentum feugiat sem quis interdum. Vestibulum tempus lectus a augue viverra molestie.

Clarification on registering a job service
by Zimmel, Daniel 06 May '21

06 May '21

Hi, can someone clarify on the following behaviour? The docs say: "Job services can be updated: If a new job is registered, and if there is already a job with the same id, the old entry will be replaced." https://docs.basex.org/wiki/Jobs_Module#Services So when I try to update an existing job service with the following query, I get an unexpected error "Job id already exists: myquery.": jobs:eval( xs:anyURI('myquery.xq'), (), map { 'id':'myquery', 'start':'19:00:00', 'interval':'P1D', 'service': true() } ) Am I reading the documentation wrong? Thanks Daniel

Hi Mikhail (cc to the list), If your queries generate hundreds of Megabytes, you could check if the full result is actually required. If yes, you may need to check which step is responsible for letting you wait: Is it the pure transmission over the network, is it the evaluation time or is it the client that processes the query result? If it’s the data traffic, and if you use Jetty as BaseX web server, you could enable GZIP compression [1]. If you use another web server, or if your architecture is more complex, you could install a proxy in between that takes care of compressing the transferred data.

My BaseX server is hosted in AWS, while the Power BI server is located internally. The communication takes too much time, which is a show stopper for me.

Hi there. I have recently been looking at ways to improve the efficiency of my XQuery server and have come across Efficient XML Interchange (EXI) Format. Is there a way that BaseX could support encoding/ decoding for this format? Thanks. Mikhail

Thanks Marco, I understand. As an aside for others, a GO edge router with BaseX is another option - say https://github.com/thomseddon/traefik-forward-auth. OIDC, ACME and SSL are all built in. BaseX can trust / check the forwarded cookie as part of BaseX permissions checking. https://docs.basex.org/wiki/Permissions Adam On Mon, May 3, 2021 at 6:00 PM <basex-talk-request(a)mailman.uni-konstanz.de> wrote: > Send BaseX-Talk mailing list submissions to > basex-talk(a)mailman.uni-konstanz.de > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.uni-konstanz.de/mailman/listinfo/basex-talk > or, via email, send a message with subject or body 'help' to > basex-talk-request(a)mailman.uni-konstanz.de > > You can reach the person managing the list at > basex-talk-owner(a)mailman.uni-konstanz.de > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of BaseX-Talk digest..." > > > Today's Topics: > > 1.

Make use of external Identity Management for BaseX

Hi, I have a question. Can BaseX make use of an Identity Management application like Keycloak for Users? I can’t find anything about it :) With kind regards, Rob Tjalma

Reloading jars on a running http server.
by Reece Dunn 30 Apr '21

30 Apr '21

Hi all, I'm working on a Java class that I'm importing into an XQuery, so I can do additional processing on the data that isn't easily expressible in XQuery (or XSLT). In order to get BaseX to pick up a modified version of the jar file I'm building, I'm restarting the BaseX http server. This makes it slower to turn around testing the changes. Is there a better way of doing this? Kind regards, Reece

7.9 to 9.4 upgrade
by Bondeson, Carl 28 Apr '21

28 Apr '21

We have been using BaseX for about 10 years. We were stuck at 7.9 because the performance of 8 was too restrictive. We tried 9.4 as a last ditch effort to correct some issues and the performance was just as good as 7.9. You made mention that many tcp/ip issues were resolved. We are using BaseX in a multithreaded client server configuration. I have architected a singleton as the server, allowing synchronized clients access to it. Everything is fine until we are under heavy load. We get the following error. IO exception Software caused connection abort: socket write error in mapperProcess query: declare option output:item-separator ""; distinct-values(for $h in //Concept[@NameSpace='Pilotfish.MergeLevel'] for $d in //Concept[@NameSpace=$h/AssociatedConcept/@NameSpace and .=$h/AssociatedConcept/@Concept] where $h/@Value='ByProductCodeDaily' return $d/@Value) retries: 9 We try 8 times, with a 100 msec wait between each attempt, and then generate an exception on the 9th. We have added tcp/ip registry fixes (MaxUserPort, TcpTimedWaitDelay) to the Windows server as a recommended fix for these types of errors. Do you have any other suggestions? Thanks for a great product!

BaseX and Oxygen scenario
by Zimmel, Daniel 22 Apr '21

22 Apr '21

Hi, am I right in assuming that in order to use the XQJ interface as described here (https://docs.basex.org/wiki/Integrating_oXygen) , you will always need a running local database instance of BaseX? I am not able to use the BaseX.jar standalone in a transformation scenario as I would for example do in a custom ant scenario where I can use BaseX as a standalone transformer (using it as a commandline process). Thanks, Daniel
