-To avoid redundant data in transactions, the digital asset model is different for `CREATE` and `TRANSFER` transactions.
+To avoid redundant data in transactions, the asset model is different for `CREATE` and `TRANSFER` transactions.
 
-A digital asset's properties are defined in a `CREATE` transaction with the following model:
+In a `CREATE` transaction, the `"asset"` must contain exactly one key-value pair. The key must be `"data"` and the value can be any valid JSON document, or `null`. For example:
 ```json
 {
-    "data": "<json document>"
+    "data": {
+                "desc": "Gold-inlay bookmark owned by Xavier Bellomat Dickens III",
+                "xbd_collection_id": 1857
+            }
 }
 ```
 
-For `TRANSFER` transactions we only keep the asset ID:
+In a `TRANSFER` transaction, the `"asset"` must contain exactly one key-value pair. They key must be `"id"` and the value must contain a transaction ID (i.e. a SHA3-256 hash: the ID of the `CREATE` transaction which created the asset, which also serves as the asset ID). For example:
 ```json
 {
-    "id": "<asset's CREATE transaction ID (sha3-256 hash)>"
+    "id": "38100137cea87fb9bd751e2372abb2c73e7d5bcf39d940a5516a324d9c7fb88d"
 }
 ```

-- `id`: The ID of the `CREATE` transaction that created the asset.
-- `data`: A user supplied JSON document with custom information about the asset. Defaults to null.
