Chaals,

I think you have misunderstood me. Access mode works perfectly well. Teachers' Domain is built on access mode plus access features a.k.a media feature. 

You said in the last meeting that search engines would not make decisions on the Web the way TD does so I was working with Liddy's suggestion of sets of "necessary" access modes on the assumption that it would meet a search engine's needs better. But I think that us better derived from access mode during indexing. 

Access mode is the simplest information we can ask for from mainstream metadata authors. I continue to believe that for that reason it should be in vocabulary that we disseminate for broad adoption.

I think this proposal is much closer to a workable way of defining accessMode, but I think you have added stuff that doesn't belong here.

That said, it seems extremely valuable to have the information, because it can be used to improve matching of users and resources. With relationships defined in a machine-readable way (RDF or some similarly clear model for describing related terms) I think we can make a lot of use even of existing mediaFeature metadata.

We can take the same names in schema.org, and retire the original name/namespace combination. But for stuff that we want to change, it makes more sense to me that we change everything at the same time...

IMHO mediaFeature needs better definition but the terms, and therefore the markup we find in the wild, are OK. I think we want to replace accessHazard with a negatively expressed version ("doesNotHaveAccessHazard") but in the meantime I think adopting the existing accessHazard would be a good idea.
