Swagger Editor 3.0 How to code component schemas for java maps - validation

Question

I have an response schema that contains java URI, Set and Map.
I can't find any example how to code this yaml part for swagger.
How to write the URI, Set and Map part in yaml components: schemas: see below.
My response java code looks like below.
public class ShowStaticInfo {
private String Id;
private long time;
private URI poster;
private Set<Tag> tags;
private HashMap<String,Tag> objectCreated;
And the written yaml code like this.
As stated above this yaml needs to be changed.
