What does “Create a domain model via POCO classes” means?

问题

I have an assessment to solve. In the project solution which is given to me, there is a .csv file expected from me to process it. Here is how it looks like;

asset id,file_name,mime_type,created_by,email,country,description

The applications which is asked from me to complete is like this;

// Create a domain model via POCO classes to store the data available in the CSV file below
// Objects to be present in the domain model: Asset, Country and Mime type
// Process the file in the most robust way possible
// The use of 3rd party plugins is permitted

So from what I understood from these steps, I have implemented a class structure;

    public class Asset
    {
        public int assetID { get; set; }
    }

    public class Country
    {
        public int countryName { get; set; }
    }

    public class Mime
    {
        public int mime { get; set; }
    }

But about the lack of theoretical concept behind POCO, I am not sure what I am doing, or what should I do.

Is that a correct "domain model" what I implemented?
Where I should use the other headers such as "file_name", "email" which is stated in .csv file?

Thanks in advance.
