Mark A. Matienzo

Collaboration & Interoperability Architect, Digital Library Systems and Services

As Collaboration & Interoperability Architect within Digital Library Systems and Services (DLSS) at the Stanford University Libraries (SUL), I serve as an expert in the software, standards, architectures and models for technologies for libraries, archives and museums (LAMs). My role at Stanford is both as a technologist (focusing on data modeling and API design) and as an advocate and facilitator (focusing on training, collaborative practices, and shared software development projects). Along with my colleagues in DLSS, I help organize LDCX, an annual unconference for technologists in the cultural heritage sector.
