+description: Using Umbraco entities as reference with an UI Builder collection
+---
+
+# Entity Identifier Converters
+
+Umbraco stores identifiers in UDI format for most Umbraco object types.
+
+You can read more about them in the [UDI Identifiers](../../umbraco-cms/reference/querying/udi-identifiers.md) section of the documentation.
+
+If you want to reference an Umbraco object in your model and retrieve its `Integer` or `Guid` value, you must convert the `UDI` value.
+
+Use one of UI Builder's converters - `EntityIdentifierToIntTypeConverter` or `EntityIdentifierToGuidTypeConverter`. Add it as a `[TypeConverterAttribute]` to your model's foreign key property.
+
+An entity that references an Umbraco object would look like this:
+
+```csharp
+    [TableName(TableName)]
+    [PrimaryKey("Id")]
+    public class MemberReview
+    {
+        public const string TableName = "MemberReview";
+
+        [PrimaryKeyColumn]
+        public int Id { get; set; }
+
+        public string Title { get; set; }
+
+        public string Content { get; set; }
+
+        [TypeConverter(typeof(EntityIdentifierToIntTypeConverter))]
+        public int MemberId { get; set; }
+    }
+```
+
+You can also create a custom type converter. UI Builder will handle data persistence automatically.
