Overview
The article discusses the technical challenges of data sharing, emphasizing the principles of access and sharing across three dimensions: What (content), Why (purpose), and Who (users). It also outlines capabilities and workflows that facilitate effective data sharing while ensuring compliance with data usage agreements.

Key Questions Answered
What are the three principal dimensions of data sharing?
The three principal dimensions of data sharing are What (content), Why (purpose), and Who (users). These dimensions help define the specific access and sharing requirements for data, ensuring that it is shared appropriately and securely.
How does provenance enhance trust in data sharing?
Provenance enhances trust by providing a clear history of how data was derived, who produced it, and when it was created. This transparency allows users to assess the reliability and relevance of the data, which is essential for effective collaboration.
What role does access control play in data sharing?
Access control determines whether a user can access a specific information resource for a given purpose. It is essential for enforcing data usage agreements and ensuring that data is used only as intended, thereby protecting sensitive information.
What is a redact and release workflow?
A redact and release workflow involves creating a derived dataset from source datasets where sensitive information is removed. This allows data owners to share non-sensitive data while maintaining compliance with access controls and data governance policies.
Key Actionable Insights
1Implementing a provenance graph can significantly enhance data trustworthiness.By tracking the origins and transformations of data, organizations can provide transparency that builds trust among users and facilitates compliance with data governance requirements.
2Establish clear access control policies that differentiate between mandatory and discretionary controls.This differentiation helps ensure that sensitive data is protected while allowing for flexibility in data sharing, thus enabling efficient workflows without compromising security.
3Regularly audit data access logs to ensure compliance with data governance policies.Auditing helps identify unauthorized access attempts and ensures that data sharing practices align with established agreements, thereby mitigating risks associated with data breaches.
Common Pitfalls
1
Failing to properly define user roles and permissions can lead to unauthorized data access.
This often occurs when organizations do not regularly update their access control lists or fail to consider the evolving nature of user roles within the organization.
2
Neglecting to maintain a clear provenance for data can undermine trust and compliance.
Without a well-documented provenance, users may question the reliability of the data, leading to hesitance in its use and potential compliance issues.
