Hi all,

First, I'm just back from DH2017, where Clifford Anderson and I taught two workshops on XQuery using BaseX, along with eXist and Saxon. BaseX performed like a champ. We were able to configure the GUI window to show just the query and results windows—perfect when you're projecting the screen in a large room and want everyone to see. Many thanks for such a great teaching tool! (Our materials are at https://github.com/CliffordAnderson/XQuery4Humanists.)

Back to the topic of this post, though, I noticed a slight difference between BaseX's serialization of arrays when using JSON vs. adaptive methods: with JSON, the array's items are separated by newlines, whereas with adaptive, the items are separated by spaces. This is interesting since the serialization spec notes that the adaptive method delegates the handling of the "indent" parameter to JSON. Some code to reproduce this is below.

I'm curious to know - is there a particular reason for this difference?

Thanks,

Joe

let $serialization-parameters :=

<output:serialization-parameters>

<output:indent>yes</output:indent>

</output:serialization-parameters>
