“Being able to refer to written definitions of our data elements has made it so much easier to create accurate, up-to-date reports that our users actually trust.”

Organize your glossary
the way you want
A Term is the fundamental unit of your glossary. It can be a KPI definition, metric formula, or business taxonomy — it’s up to you. The special part? Group collections of Terms into Categories, and create multi-level hierarchies that mimic the way you work.

The connected semantic layer
for your business
In Atlan, the glossary is more than just a dictionary. It’s an activated knowledge network for your business, where you can create relationships between definitions, metrics, and assets.

Everyone suggests, you approve
Get rid of tribal knowledge with Requests. Anyone with view access to data can suggest owners, missing terms, or a change to the description. It’s in your hands to approve.
“We want to surface everything in the enterprise to the users, but restrict some data in terms of access. I have to go through a request process, but we don’t want to stop them from seeing what exists.”

“Atlan wasn’t built as just a catalog management tool. It’s really a home for data people to collaborate, discuss things, and come together.”
