A Service Book on Cardano … too early ?  
Utilizing blockchains to capture the history and service history for products is a common usecase for blockchains. See i.e. [gapless](https://www.gapless.app/).

With the advent of NFTs i was wondering well Cardano is already capable to capture the product & service history of a product.

Imagine you bought a new bicycle and alongside your purchase you receive an NFT which documents your owner ship of the bike.  
Whenever you bring the bike to service or reclaim a warranty issue the information is attached to your blockchain.  
Same would be possible for almost every product of interest. Watches, Electronics, Machinery … you name it!

Which bits of pieces do we already have at mainnet today?

[Transaction Metadata](https://github.com/input-output-hk/cardano-node/blob/master/doc/reference/tx-metadata.md) is probably the foundation, while a Wallet with a simple interface to sign / extend a transaction similar to what Metamask is doing in the Ether Space is still missing?

If you know anything interesting along the lines, may it be a cardano project, ether project or catalyst initiative on ideascale I would appreciate your input!

Found this presentation shared by @adatainment to be a good starting point for metadata [Metadata Workshop 01/18/21 - Google Slides](https://docs.google.com/presentation/d/1ursHchJiBP5ZVuXcW2uVJMmzXjlJk_di65CKmAplEy4/edit#slide=id.gb7121fc2c5_2_7)
