Exposing ScriptableObject to DOTS

I have some data as ScriptableObject and want to expose it to DOTS. I intend to do it through BlobAssetReference.

I can create BlobAssetReference in IConvertGameObjectToEntity.Convert.
To prevent duplication I could use conversionSystem.BlobAssetStore and use ScriptableObject GUID as Hash

Is this correct approach?
Will this work with LiveLink? (should I use BlobAssetComputationContext?)
- I mean sending ScriptableObject modifications through LiveLink
- I guess not, because it's not even working for Prefabs?

When I create BlobAssetReference and assign it to component, who will Dispose it?

Code (CSharp):

1. public class ObjectWithDefinition : MonoBehaviour, IConvertGameObjectToEntity
2. {
3.     public SimpleDefinition Definition;
4.     public int Value;
5.  
6.     public void Convert(Entity entity, EntityManager dstManager, GameObjectConversionSystem conversionSystem)
7.     {
8.         var hash = new Unity.Entities.Hash128(UnityEditor.AssetDatabase.AssetPathToGUID(UnityEditor.AssetDatabase.GetAssetPath(Definition)));
9.  
10.         if (!conversionSystem.BlobAssetStore.TryGet(hash, out BlobAssetReference<SimpleDefinitionData> blob))
11.         {
12.             SimpleDefinitionData def;
13.             def.Name = new Unity.Collections.NativeString32(Definition.Name);
14.             def.Value = Definition.SomeValue;
15.             blob = BlobAssetReference<SimpleDefinitionData>.Create(def);
16.             conversionSystem.BlobAssetStore.TryAdd(hash, blob);
17.         }
18.  
19.         ObjectWithDefinitionData data;
20.         data.Definition = blob;
21.         data.Value = Value;
22.         dstManager.SetComponentData(entity, data);
23.     }
24. }
25.  

 

I have made a utility framework of my own you can use directly or as a point of reference:

Thanks, I see it works in similar fashion. Do you have an idea what destroys created BlobAssetReferences?
Also what creates ScriptableObjectConversionSystem or do I have to create somehow?
