Re: EOCred: cost of a credential

I have attempted to express some of the discussion around providing 
information about costs of credentials and associated courses and 
assessments on the EOCred wiki 
<https://www.w3.org/community/eocred-schema/wiki/User:Philbarker/Draft:_costs_for_educational_/_occupational_credential>

The general principle is to describe costs of independent things 
separately, so that they can be aggregated in an intelligent and 
context-dependent manner, but where the /offer/ of one thing is 
dependent an /offer/ of another, use the addOn property.

I recognise that this is incomplete. It depends on things in schema.org 
that don't yet exist, but also I don't think we can hope to cover every 
eventuality.

I am interested in how far this goes to meeting the objection that 
Stuart expressed about the initial over-simple proposal, and whether it 
includes enough information to cover the possibilities Richard has been 
highlighting.
