OData with power BI API?

Hi,

We use the power BI API to insert the dataset and the data from our java program.
How can we use the api to get the full definition of the dataset? (dataset, table, colums, types...)

Now When we retrieve the dataset and tables, we can see just the table name... but we need also to see columns and the columns type. How to do this?

I read also that power BI made some OData compatibility, but on the api website there are no examples of this...
