Validator Compatibility with WMS Versions < 1.3.0 #1018

Open lvgl-cs opened 5 months ago

lvgl-cs commented 5 months ago

Hello,

I am currently encountering an issue with the validation of WMS versions earlier than 1.3.0. The validator returns the following error message:

I’d like to ask whether the validator is designed to support versions earlier than 1.3.0. Maybe I just have to do something different. If not, I am interested in the possibility of enhancing the validator to include earlier versions.

Your assistance in providing insights on this matter and possibly resolving this issue would be highly appreciated.

Best regards, Carsten Sommer (GDI Saarland)

Dear @lvgl-cs,

thank you for opening the issue, could you please provide the test resource to replicate the error?

Dear @fabiovinci,

sure, this is the URL I used: https://geoportal.saarland.de/mapbender/php/wms.php?layer_id=35634&PHPSESSID=330unelcq8lu9qe2bdcmgi1mfh&REQUEST=GetCapabilities&VERSION=1.1.1&SERVICE=WMS

If the additional custom parameters might also cause the issue, please let me know. I added a comment to the discussion related to this topic (https://github.com/INSPIRE-MIF/helpdesk-validator/discussions/1015). But due to the error I receive from the server, I assume that the version is causing a different problem.

Best regards

Dear @lvgl-cs,

a TG change proposal to deprecate WMS 1.1.1 in INSPIRE has been opened and will be discussed in the next MIG-T meeting. You can find more information about the change proposal in the link above.

There are various reasons to support this proposal:

WMS 1.1.1 is a deprecated standard
the base standard for the INSPIRE View services is WMS 1.3.0
the Validator (which currently uses ETF 2.0) does not support WMS 1.1.1
WMS 1.1.1 uses DTD and requires the DOCTYPE declaration. For security reasons, DOCTYPE and DTD should not be allowed (see reference) and, for sure, they are not allowed in the ETF 2.1 (version on which the next versions of the validator will be based).

We will update the issue with the results of the approval process of the change proposal, but, in any case, there are no plans to work on WMS 1.1.1 support.
