Do I have to write documentation about the metadata I’ve created for future web managers to refer to if they need to?
This would be useful as it establishes the business process to create, maintain and manage metadata on your site. It would be worthwhile to include those elements of the AGLS standard that you see as mandatory from your organisation’s perspective and any rules for their use including the use of functional or subject-based thesauruses. Such documentation would also be useful for resource creators in understanding their information management responsibilities.
