What is FarmStack?
FarmStack is a reference implementation of an open and interoperable data sharing protocol in agriculture sector. FarmStack enables network of data providers and consumers through a suite of products and functionalities:
Share data directly without any third party through trusted peer to peer (p2p) connector
Empower the data provider to restrict usage of data through usage policies
Give control of data back to the farmers by managing consent using data wallet
Enable entities to create plugins to make their data discoverable (description of data)
FarmStack is the sum total of all the peer to peer connectors and associated usage policies.
Why is FarmStack required?
FarmStack is required because:
Relevant farmer profile including farmer activity not available
Lack of trust on misuse or under utilisation of data with a centralised data warehouse
Need to comply with evolving data policy and privacy safeguarding measures
Existing data integration tools lack the customisation
Value generated by FarmStack
By combining specific datasets, better services or products can be created
Organisations can discover what data resides with whom to foster collaboration
Potential to unlock value of data that was previously considered not shareable
More feedback from lead to more enriching solution - giving rise to virtuous cycle
How does FarmStack network look like?
A typical FarmStack network looks as below with three distinct roles the actors in the network can play. Farmers are the end beneficiaries who consume services offered by one or more participants and can have their data wallet using which they manage consent to share data to specific organisations in return of anticipated returns. The participants are the organisations that maintain the data for the services they provide and exchange data. They run the FarmStack software on their own premise to manage connectors using which they enforce usage restrictions as per the consent. The participants get access to the software once they register with the steward who maintains and oversees the network.

Business roles in FarmStack
Roles | Activities | Interface | Incentive |
|---|---|---|---|
Farmers | Manage consent to share data that could be managed by self or an organisation | Data wallet | Control data Get connected to services |
Participants | Organisations that exchange data and manage connectors and usage policies based on consent | FS Participant | Respect farmers' rights Offer better services |
Steward | Nodal agency who manage subscription of the participants (issue certificates, logs transactions etc) | FS Steward | Drive data sharing policies Sustain a network |
How will someone use FarmStack?
There are two ways to set up FS participant software: a) obtain the FS participant software from the first steward, Digital Green and start managing the connectors and usage policies or b) service based model where FS team from Digital Green can deploy the software for interested participants and hand over. There is no difference between the two in terms of functionality of data exchange.

Examples of policy based usage control (not comprehensive list)
This is just to give examples of usage policies for the purpose of documentation. This is not the immediate usage policy.
Below are the categories of use cases and examples for that.

Usage of data fields restricted to specific operations like joining
Usage of data fields restricted to specific operations requiring logging
Usage of data fields restricted to specific operation for a limited number of times
Usage of data fields restricted to specific operations for a certain time period
Visible with constraints
Only some part of data available for viewing for specific time period
Specific data fields can be viewed by specific persons in specific organizations
Shareable with constraints
Can be shared to specific organisations with them only able to view or perform specific operations
Can be shared with logging and notifications
Can be shared for limited number of times
Can share only specific data fields
Downloadable with constraints
Can download specific data fields
Stored with constraints
Can be stored but in encrypted form at specific instance
Can be stored for usage only for specific operations
Can be stored for usage only for specific time and operations
