Imagine wanting to reconstruct Venice's entire history, document by document, map by map, in a giant digital archive. That's the Venice Time Machine challenge. But researchers warn: scanning millions of pages isn't enough. We need an approach that unites bits and people.
A study published in *Heritage* applies **Socio-Technical Systems (STS)** theory to digital heritage. The core idea? Technology (hardware, software, algorithms) and society (historians, citizens, institutions, policy) aren't separate worlds. They are subsystems in constant interaction. If you optimize only the scanning but ignore who will use the data or how it's preserved long-term, the project fails.
The study compares six STS models using Venice Time Machine as a test case. The result: managing complexity requires **"joint optimization."** This means designing with four pillars in mind: cultural expression (what we tell), technological feasibility (how we do it), stakeholder interests (who benefits), and long-term adaptability (will it survive in 20 years?).
Thus the **STS-DH framework** is born: a practical toolkit to design, launch, and evaluate digital heritage projects. The message is clear: digital heritage isn't a database, it's a living ecosystem. And empirical research on this front is just beginning.
