I'm trying to upgrade my SDN application to SDN 6 and right now don't know how to upgrade the following construction:

```
@Properties(prefix = "property", allowCast = true)
private Map<String, Object> properties;

```

How to define it in SDN 6? Thanks!

X-Post from: [Spring Data Neo4j @Properties annotation - Stack Overflow](https://stackoverflow.com/questions/67555768/spring-data-neo4j-properties-annotation)

You would use the `@CompositeProperty` annotation. This will work with `Map<String/Enum, Object>` .

Here is the link to the documentation with some further information. [Spring Data Neo4j](https://docs.spring.io/spring-data/neo4j/docs/current/reference/html/#custom.conversions.composite-properties)

Thanks for your answer! Unfortunatly, I unable to fully test it right now because blocked with [Migration to SDN 6 - issue with relationship between nodes](https://community.neo4j.com/t/migration-to-sdn-6-issue-with-relationship-between-nodes/38456)

Also, one addtional question regarding `allowCast = true` attribute of `@Properties` annotation. I do not see the same attribute for the `@CompositeProperty`. Do we still need it or `@CompositeProperty` will work out of the box without such attribute? Thanks!
