Is it possible add metadata to binarycache offchain transaction in a stream?

Question

Hi,
I'm working saving files using binarycache and publishing it in a stream with the following command via multichain-cli:

publish stream1 key1 '{"cache": "aHAN7Z9jF4S"}' offchain

So the question is:

Is it possible to add metadata with an JSON object and save the JSON object on-chain, and the binary cache off-chain with the same transaction?

Answer 1

Yes, you can do this, but it would require a second stream item (containing the JSON) to be published in the same transaction. You could put this item in the same stream or a different stream – the choice is yours – and the two items would be naturally associated with each other by having the same transaction ID. See the publishmulti command which can make this easy.

That's exactly what I need. Thanks for the quick response. I'll take a closer look to the API documentation.
