Doubts: Am I doing it right?

Am I doing this right?

What I had hoped to show you:

Finished website Attestations to Pleiades Partial linking to Nomisma RDFa through out all pages Content negotiation

Someone arrived 6 weeks early

What aspects can I link to?

People Places – eg Pleiades places Time Events Citations/ references Museum objects eg all BM/ANS denarii Books

Enriched by Amazon via ISBN

I use the affiliate programme in the vain hope of us making some cash!

I could of course link to open bibliographic projects.
