Usecases of OpenSearch in INSPIRE Atom

[arbakker]

Hi, I am with the Dutch Kadaster and as such we are managing the Dutch national catalogue and many other INSPIRE services.
We recently put effort in improving our INSPIRE compliance with respect to our OpenSearch implementation in our INSPIRE Atom feeds. That made me wonder if anyone knows of a use case of OpenSearch in relation to the INSPIRE Atom, that is used in practice. I do not know of any use cases of OpenSearch in the ATOM services we manage.

So I am curious to see if there is any use of OpenSearch, since I am unaware. My intention is to start a discussion on the benefit of OpenSearch requirement in the INSPIRE Atom download service. With the current information I have at my disposal I do not see much benefit of OpenSearch for INSPIRE Atom services, other than compliance.
