# Configuring an external dictionary
|
||
|
||
The dictionary configuration has the following structure:
|
||
|
||
```xml
|
||
<dictionary>
|
||
<name>dict_name</name>
|
||
|
||
<source>
|
||
<!-- Source configuration -->
|
||
</source>
|
||
|
||
<layout>
|
||
<!-- Memory layout configuration -->
|
||
</layout>
|
||
|
||
<structure>
|
||
<!-- Complex key configuration -->
|
||
</structure>
|
||
|
||
<lifetime>
|
||
<!-- Lifetime of dictionary in memory -->
|
||
</lifetime>
|
||
</dictionary>
|
||
```
|
