# Prerequisites

Before you begin using the query language used in the Output Module, you must understand the Collibra API model and how to execute REST calls. This guide shows examples that query the REST API but does not explain how to execute REST calls. Refer to external online resources for tutorials and instructional resources.

## Terminology

The Collibra API model was based on the Semantics of Business Vocabulary and Rules (SBVR) standard. Over time, the user interface adopted a simpler terminology set that aligns with Collibra concepts. Since version 2021.09 (5.7.10 for on-premisses), the Output Module API uses the same terminology as the user interface while the legacy one is deprecated.

The following table lists the renamed terminology:

| Deprecated                        | Current          |
| --------------------------------- | ---------------- |
| Term                              | Asset            |
