Swagger Editor 3.0 How to code component schemas for java maps

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.
