Hi Christian,
I'm experimenting with dynamic modul loading using: 'load-xquery-module'. I have a few questions concerning this function:
- Does this function cache the loaded modul like "import module" does? If I interpret the profiling data correcty, it does not. If so is it possible to also cache dynamicly loaded modules?
- "location-hints" of this function accepts a set of locations. It seems that all these locations must contain a module with the given modul-uri. I would expect the one would be sufficient. What is the idea behind this locationset?
Thanx in advance for your response.
mvgr.

Hi Rob,
I have finally added an issue to support caching for load-xquery-module; we’ll see what we can do [1].
Best, Christian

Hi Rob,
there is currently no caching for modules loaded via load-xquery-module, rather the module source is accessed with each invocation. However as the function is defined as "deterministic", it should guarantee within a single query execution to return the same results for the same parameters. Which it currently can't - thanks for pointing this out. We will take care of this to make sure that a module source is accessed only once per query execution.
The multitude of "location-hints" mirrors the multitude of URILiterals following the "at" keyword of "import module". This is because a module is explicitly allowed to be split across multiple sources. So the behavior of "location-hints" is that of "import module": each source is expected to contain a part of the module.

Hi Rob,
modules that are parsed with fn:load-xquery-modules and with the same (and a single) "location-hints" option are now cached and reused. An updated snapshot is available; your feedback is welcome [1].
Best, Christian
