Schema.org for news websites?

[HalogenDigital]

So as of late I have been on something of a mission to mark up my news website with as much accurate and detailed Schema and Open Graph data as possible, in order to not only allow the search engines to understand my content properly, but also to ensure everything appears in the most ideal fashion when linked to from Facebook, Google+, etc.

Here is an example of a typical article page: http://www.nerdscoop.net/technology/video-games-459

As you'll see I currently have news posts marked up as article because that is essentially exactly what they are, but is there a better way to emphasise that they are news rather than just generic articles?

My second question is regarding the category pages and the home page. How would be best to mark these up? With OG the task is fairly simple, because I can specify the homepage as being a website, but not so with Schema from what I can see.

Either way, this is an interesting subject to me and I look forward to any discussion as a result. Thanks for looking.

Nobody has any input on this?
