# ASEE Flow Spin Dataformat Reference

ASEE Flow Spin is a library for simple XML and JSON processing on the JVM (Java
Virtual Machine), targeting Java and JVM-based scripting languages such as
Groovy, JRuby, Jython, JavaScript and Java Expression Language. It provides a
comprehensible fluent API for working with different data formats through
lightweight wrapper objects.

Spin can be used in any Java-based application by adding the following maven
dependency to your `pom.xml` file:

<Note>
  **ASEE Flow BOM**

  If you use Spin in combination with the ASEE Flow process engine,
  please consult the [process engine user guide on Spin integration](/user-guide/data-formats/configuring-spin-integration)
  on how to properly integrate Spin with the engine.
  Please import the <a class="alert-link" href="/get-started/apache-maven">ASEE Flow BOM</a> to ensure that you use the ASEE Flow Spin version matching your process engine
  version.
