how are schema's loaded, if they also exist locally?

[pvgenuchten]

This issue was mentioned by dries luts around the inspire soil schema.

Jrc recently deployed some bugfixes on various schema's. Our impression is that when we try to load these updated schema's by url, hale studio seems to still use the locally cached previous version of the schema

I wonder if there is guidance available on how to update the locally cached/preset schema's, and/or if software changes could improve this use case (check if the online version is newer then the local one).

I could also imagine we should encourage jrc to not fix issues on previously published schema's but publish changes on a new minor release version (4.0.1)

The mechanism with the offline resources in hale works in the way that for a given host name, hale first tries to find the resources (e.g. XML Schema) in the offline resource bundles and if it does not find them it will use the online resource.

This assumes that the content at the respective URLs is stable (as they usually contain a version number). Past experience has shown that at least for the INSPIRE schemas, but also for instance for OGC schemas like the GML 3.2.1 schema the online resources have changed.

The approach in the past was to then just update the resource bundles. The latest versions can be found here - you can see those are already over a year old. There is an automated build available in that repository, to create new versions of the bundles by downloading the schemas (it might have to be checked though if these still work as expected).

To force your hale studio to not use the offline resources you could also just delete the respective bundles from the pluginsfolder (e.g. removing files similar to eu.esdihumboldt.util.resource.schemas.inspire_2021.03.09.jar to remove the INSPIRE schemas).

Thanx for the hint @stempler
I'll give it a try

@stempler, I was not aware of it but it seems JRC also publishes a versioned edition of the INSPIRE xsd's at

https://inspire.ec.europa.eu/schemas/2021.1/so/4.0/Soil.xsd
https://inspire.ec.europa.eu/schemas/2021.2/so/4.0/Soil.xsd

At least, by using this url, it is a better workaround then removing the preset package, but maybe the Hale software should also adopt these versioned xsd url's?

@pvgenuchten As the bundled resources have been updated in the meantime, would you agree that we can close this issue?
