Tested as part of Schema Team's schema testing:

The above applies to both schemas, RNG and XSD.

The attribute is ready.

Call for comments feedback from EAD team:

In their meeting on 21 May, the EAD team of TS-EAS discussed the attribute @lastDateTimeVerified and the question of whether or not this should also be enable with the other external linking attributes, i.e. the three new vocabulary attributes. In the course of the conversation, we wondered (1) if there are applications of the EAS out there, where checks on links are actually done regularly, and (2) how helpful this information is from a user's point of view in case the link is broke. E.g. if a link is not accessible anymore or gives an error message, how useful is it to know that this same link had been working three months ago?

We would hence like to suggest consider removing the attribute completely and to point to the option of @localType or <localControl> (if kept) for customisation to local/specific use cases or to the option of using attributes from any other namespace (to be checked whether there could be recommendations for other XML schemas providing such information).

EAC-CPF team meeting, 8 Aug 2021:

Agreed to remove this attribute as it is underused and a relict of early internet days.

This update is ready to be tested: https://github.com/SAA-SDT/eac-cpf-schema/commits/issue/233.

I also went ahead and merged this with the development branch, since it was such a minor change and I had the time. If I need to update anything later, just let me know.

kerstarno commented 2 years ago

Re-tested with the XSD and RNG schemas available in the development branch (status of 8 January 2022).

I can confirm that neither schema includes @lastDateTimeVerified anymore. For none of the elements that previously allowed for the attribute (<representation>, <source>, <reference>, <contactLine> and <setComponent>), it is offered as an option and when trying to add the attribute to any of these elements, this results in a validation error.
