Will need to include the API design for retrieving data.

Here's an example of some JS code that uses Rchain-API to query for results: https://gist.github.com/JoshOrndorff/b0fe7aed93d16beabc2885484c6e8c54

	Requirement	Description	Priority	Notes
1	Retrieve data asynchronously	As a mobile app developer, I need to send all my request asynchronously, so that my apps are fast.	Must Have	The RSong demo requests the song, song metadata and song artwork asynchronously. It's not clear to Medha if this is a hard requirement. There isn't any reason why the song can't be requested first, followed by the metadata.
2	Monitor Requests for Data	As a validator, I need to know how much of my node's resources are spent on data access requests so that I can set the prices for transactions properly.	Must Have	There has to be a dashboard that shows how many requests for data the node is servicing. There should also be a dashboard that shows how much data is being returned in these requests. This metric can be in aggregate if needed.
3	Performance	In principle, A dApp developer will want to provide a user a transaction receipt with at least the same speed at which the transaction itself is processed.	Must Have	This means that half of the transaction processing time is in fact, in the retrieval of the transaction confirmation.
4	Deployment ID	Each deployment has a userid and timestamp, userid (public key associated with private key used to sign transaction ) for that particular deployment by the client software. These keys should be looked up in the block store.	Must Have	Users need a way to retrieve transaction receipts for their deployments.
