13. 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 TTL

28. 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
