# Bootstrapped Model Data

The Klass metamodel is part of every Klass model. When a Klass application starts, it "bootstraps" the metamodel by populating model data into the data store. This means that in the Stack Overflow application, we can GET /api/meta/class/Question to get the Question class as data.
