To Reproduce Steps to reproduce the behavior:

1. Go to 'https://co-cddo.github.io/ukgov-metadata-exchange-model/Distribution/#examples'
2. Click on 'Distribution-os-postcodes-csv-distribution-minimal'
3. See 404 Not found error

Expected behavior The JSON representation of the example should be displayed.

Additional context This relates to an underlying problem in the LinkML framework that has been reported in https://github.com/linkml/linkml/issues/1508

I could not reach the enum values as well. They returned 404 page. Are those having the same/similar issue?

No those are not related to this issue. Each of your URLs has an extra directory on the end, they should be

• https://co-cddo.github.io/ukgov-metadata-exchange-model/OrganisationValues/
• https://co-cddo.github.io/ukgov-metadata-exchange-model/AccessRightsValues/
• https://co-cddo.github.io/ukgov-metadata-exchange-model/SecurityClassificationValues/

I see, that's OK. Then let me explain what happened in my case: there is a link for non existent page. I open this page: https://co-cddo.github.io/ukgov-metadata-exchange-model/OrganisationValues/ then click the URI: link and end with this page (404): https://co-cddo.github.io/ukgov-metadata-exchange-model/OrganisationValues/OrganisationValues

In order to get the examples displaying, and to work within the LinkML assumptions, we will need to change the way that we are defining the classes so that we start with the least restrictive and then increase the obligation.

This would mean that the property page would show the least restrictive usage rather than the common usage of the property. To overcome this, we propose to extract the URI value and place it a consistent position with the class pages and merge the Obligation and Cardinality table with the Applicable Classes table so that it would look something like the following

URI: accessRights	Class	Range	Obligation	Cardinality
Data Resource	Uriorcurie	Recommended	Multiple
Distribution	Uriorcurie	Optional	Multiple
Data Service	Uriorcurie	Recommended	Multiple
Dataset	Uriorcurie	Recommended	Multiple
