Thanks for this. Tested and seems to work as intended. I haven't run the tests.

@SarthakDudhe Thanks for working on NSS. This is really needed. We may have discussion on what you could work on : implementing the Solid notifications spec !!!! or replacing inrupt OIDC client browser with UVDSL one.

@csarven
I think none of the solid servers does this.
The information is available in the Container not at Resource level
CSS does load the information in .meta (it was added for non filesystem to be able to render in Container).
This has made .meta only Patchable which is not Solid compliant.

@bourgeoa , it is required in Solid Protocol. It is also a server-controlled header, as opposed to a resource description, which may or may not be modifiable. The other advantage is being able to get this information using HEAD instead of fetching the whole resource payload with GET.
