+# DTL Support
+
+Starting with version 3.2.0, IoP supports DTL transformations. 
+DTL the Data Transformation Layer in IRIS Interoperability. 
+DTL transformations are used to transform data from one format to another with a graphical editor.
+It supports also `jsonschema` structures.
+
+## How to use DTL in with Message
+
+First you need to register you message class is a `settings.py` file.
+
+To do so, you need to add the following line in the `settings.py` file:
+
+`settings.py`
+```
+from msg import MyMessage
+
+SCHEMAS = [MyMessage]
+```
+
+Then you can use iop migration command to generate schema files for your message classes.
+
+```bash
+iop --migrate /path/to/your/project/settings.py
+```
+
+### Example
+
+`msg.py`
+```python
+from iop import Message
+from dataclasses import dataclass
+
+@dataclass
+class MyMessage(Message):
+    name: str = None
+    age: int = None
+```
+
+`settings.py`
+```python
+from msg import MyMessage
+
+SCHEMAS = [MyMessage]
+```
+
+Migrate the schema files
+```bash
+iop --migrate /path/to/your/project/settings.py
+```
+
+## Building a DTL Transformation
+
+To build a DTL transformation, you need to create a new DTL transformation class.
+
+Go to the IRIS Interoperability Management Portal and create a new DTL transformation.
+
+![DTL Transformation](./img/interop_dtl_management_portal.png)
+
+Then select the source and target message classes.
+
+![DTL Transformation](./img/dtl_wizard.png)
+
+And it's schema.
+
+![DTL Transformation](./img/vdoc_type.png)
+
+Then you can start building your transformation.
+
+![DTL Transformation](./img/complex_transform.png)
+
+You can even test your transformation.
+
+![DTL Transformation](./img/test_dtl.png)
+
+Example of payload to test as a source message:
+
+```xml
+<test>
+  <Message>
+    <json><![CDATA[
+{
+"list_str":["toto","titi"],
+"post":{"Title":"foo","Selftext":"baz"},
+"list_post":[{"Title":"bar","Selftext":"baz"},{"Title":"foo","Selftext":"foo"}]
+}
+]]></json>
+  </Message>
+</test>
+```
+
+## JsonSchema Support
+
+Starting with version 3.2.0, IoP supports `jsonschema` structures for DTL transformations.
+
+Same as for message classes, you need to register your `jsonschema`.
+To do so, you need to invoke his iris command:
+
+```objectscript
+zw ##class(IOP.Message.JSONSchema).ImportFromFile("/irisdev/app/random_jsonschema.json","Demo","Demo")
+```
+
+Where the first argument is the path to the jsonschema file, the second argument is the package name and the third argument is the name of the schema.
+
+Then you can use it in your DTL transformation.
+The schema will be available in the name of `Demo`.
