+The metadata schema supports both long field names (`ticker`, `name`, `desc`) and compact short keys (`t`, `n`, `d`). To save space on the ledger, it’s recommended to use short key names. This is because the metadata field has a 1024-byte limit, so using compact keys allows you to include more information.
 
 The SDK libraries provide utility functions to encode or decode the metadata for you, so you don't have to. If long field names are provided in the JSON, the **encoding utility function** automatically shortens them to their compact key equivalents before encoding. Similarly, when decoding, the **decoding utility function** converts the short keys back to their respective long names.

+A Multi-Purpose Token (MPT) is a compact and flexible object that offers the best aspects of fungible and non-fungible tokens. It is the next generation of tokenization on the XRPL. Notable features include:
 
 - MPTs store metadata directly on the XRPL blockchain, with the option of linking to additional off-chain data. Once created, the metadata is immutable.
 - MPTs can have a fixed token supply, with a cap on the maximum number of tokens.
