knowledge that data can have about itself. The things that any digital object can tell you<br />

about itself, such as its origin, its location in a database, its size, and the type of object it is<br />

—whether an ebook, music video, or photograph—limit the ways in which it can be<br />

linked to other digital objects and how it can be searched for. A good example is the<br />

metadata for the digital object that represents a book in an online store. If the data doesn’t<br />

know the object represents a romance novel, that book won’t come up in searches for that<br />

category. The ability to connect, or link, digital objects may be the atomic unit of digital<br />

experiences, at the very core of what makes them work.<br />

Back-end engineers can help you develop a deep understanding of how you can use<br />

ways of linking data and objects to improve experiences. When I met the metadata<br />

engineer at my first full-time job, I sat down with her right away to find out all that our<br />

system knew to help me make decisions about navigation and page layout, and I’ve called<br />

on that knowledge again and again.
