[Chirag_]

I was thinking to create  qlik replicate as  metamodel.
So these are some steps I did to create metamodel but i am not sure how do i populate the model with Data , anyone have used metamodel please guide me on populating the model. bellow are the steps which i have done so far:

1. Create a Package

• Went to Manage > Metamodel > Start Editing

• Created a new Package named QlikReplicate

---

2. Define Reusable Attribute Types

Created attributes to be used across objects:

• taskStatus (Enum)

• schedule (String)

• lastRunTime (DateTime)

• transformationLogic (Text)

• dataVolume (Integer)

• sourceEndpoint, targetEndpoint (String)

---

3. Create Object Types

Defined custom business objects:

• ReplicationTask: to represent each Qlik Replicate job

• Endpoint: to represent source/target systems

Added the above attributes to these objects.

---

4. Define Associations

Linked objects via relationships:

• ReplicationTask → uses → Endpoint (source and target)

---

5. Create Custom Model

• Created a Model Type named QlikReplicateModel

• Added ReplicationTask and Endpoint objects to it

---

6. Save and Publish

• Clicked SAVE

• Clicked STOP EDITING to publish the metamodel
