Dr. Robert Sanderson is the Semantic Architect for the J Paul Getty Trust, with responsibility for the design and direction of cultural heritage data information systems spanning the Museum, Research Institute, Conservation Institute and Foundation.

He is chair of the JSON-LD work in the W3C and proposed chair for the W3C Art & Culture community group, is a specification editor and community leader in the IIIF community (http://iiif.io/), and on the advisory boards of many projects in the cultural sector including the American Art Collaborative and Annotating All Knowledge projects.
