Proof of Concept 4 Support

Critical for iterative framework evolution: PoC4 represents an essential opportunity to validate and refine the Property Data Trust Framework through real-world application. This proof of concept serves as a crucial feedback mechanism, allowing the framework to evolve based on practical implementation experiences rather than purely theoretical design.

PoC4 Implementation Support

• Stand up reference implementation for PoC participants
• Integrate with PoC participant systems and workflows
• Provide ongoing technical support during PoC execution period
• Facilitate real-time issue resolution and system adjustments
• Collect comprehensive feedback from all participating stakeholders
• Iterate on implementations based on participant experiences
• Document lessons learned and emerging integration patterns
• Capture use case variations and edge cases discovered during PoC
• Validate framework assumptions against real-world property transactions
• Test interoperability between different participant systems

PoC4 Framework Evolution Benefits

The proof of concept approach ensures that:

• Real-world validation: Framework specifications are tested against actual property industry workflows
• Stakeholder feedback integration: Direct input from property professionals, lenders, and other ecosystem participants
• Iterative improvement: Continuous refinement based on practical implementation challenges
• Risk mitigation: Early identification of technical and operational issues before full framework rollout
• Ecosystem alignment: Ensures the framework meets genuine market needs and participant requirements
• Standards refinement: Real-world usage informs specification improvements and clarifications
