Hello, everybody.
I am trying to build the cip68 metadata using lucid.

{
  "constructor": 0,
  "fields": [
    {
      "map": [
        {
          "k": {
            "bytes": "6E616D65"
          },
          "v": {
            "bytes": "5370616365427564"
          }
        },
        {
          "k": {
            "bytes": "696D616765"
          },
          "v": {
            "bytes": "697066733A2F2F74657374"
          }
        }
      ]
    },
    {
      "int": 1
    }
  ]
}

To build the metadata like the example above, should we use Data.Map or Data.List?
I am not sure.

Hello there,

I have gone through your post and in my opinion this is how you might create a CIP68 metadata datum using Lucid

// Import necessary libraries
import cip68

// Define metadata structure
metadata = {
“title”: “Example Metadata”,
“author”: “John Doe”,
“date”: “2024-03-04”,
“description”: “This is an example of CIP68 metadata datum”,
// Add more fields as needed
}

// Instantiate metadata object
metadataObject = cip68.Metadata(metadata)

// Serialize metadata
serializedMetadata = metadataObject.serialize()

// Store or transmit metadata
print(serializedMetadata) // For example, you might print it to the console

Also this is a basic code and might need adjustments based on the specifics of your project and the requirements of CIP68.

I hope this will work for you.

Thanks for your reply.
I found this answer actually.
Normal Javascript Map will work for Map-like Datum.
Don’t need to use Lucid Data’s Map type.

That’s great :innocent:
