Why XForms?
W3C standard web form specification
MVC architecture
XPath validation
Manipulate complex XML models*
Interacts with REST services (APIs)
*XPath/XSLT 3.0 and XSLT 2.0 should support JSON-LD and TTLSee more at http://en.wikipedia.org/wiki/XForms

Where do we go from here?
More advanced data modeling:
Periods: 550 BC implied to be Archaic Period
Techniques comprising techniques
Social network analysis
Creator roles
Places: concept/spatial thing
SKOS concept schemes
Inscriptions (link to other LOD systems)
Iconographic topic modeling
Formalize the ontology and codify the data model
But most importantly: get community buy-in
