Non-functional Requirements

Directions on the expected architecture:

• The SDK should be designed with a modular and scalable architecture, allowing future updates or the addition of new features without requiring major changes.
• It should be flexible enough to integrate with other SingularityNET services and easily extendable for future enhancements.

Specific integration requirements

• The SDK must integrate seamlessly with existing SingularityNET components such as Multi-Party Escrow (MPE), Registry smart contracts, and IPFS.
• Backward compatibility with the current Python SDK.

Programming Language:

• The SDK will be developed entirely in Golang, leveraging its capabilities for high performance and efficient concurrency management.

Security Requirements:

• The SDK must enforce secure communications for transactions, identity management, and interactions with smart contracts.
• Security mechanisms should prevent unauthorized access and ensure the integrity of operations within the marketplace.

Scalability:

• The SDK should be designed to handle an increasing number of transactions and users as the marketplace grows, without compromising performance.
• It should be optimized to scale efficiently in distributed environments, such as those using decentralized storage solutions like IPFS.

Data Quality:

• The SDK must ensure the accuracy and consistency of data transmitted between users and marketplace services.
• It should include robust validation mechanisms to handle any discrepancies in data integrity when interacting with decentralized systems like IPFS.

Reliability:

• The SDK must be highly reliable, with a strong focus on error handling and recovery from network or service interruptions.
• Rigorous testing practices (including unit, integration, and load testing) should be employed to ensure stability across different use cases and platforms.

Performance:

• The SDK should be optimized for performance, ensuring low-latency communication with marketplace services and efficient resource use (CPU, memory).
• It must efficiently handle multiple concurrent operations, especially when dealing with high-frequency service interactions.

General Modularity/composability/extensibility:

• The SDK should be built with a modular design, enabling future feature additions or service integrations without disrupting existing functionality.

Maintainability:

• The code should be well-organized and documented to support long-term maintenance, including clear comments and adherence to best practices for clean coding.
• Dependency management should be kept simple and up-to-date to avoid compatibility issues in future updates.

Usability:

• The SDK should provide an intuitive and easy-to-use API, with clear methods and functions that simplify the interaction with marketplace services for both novice and experienced developers.
• Error handling should be straightforward and include detailed messages to help developers diagnose and resolve issues efficiently.

Documentation:

• The SDK must be accompanied by comprehensive documentation, including detailed API references, setup instructions, and integration examples.
• Tutorials and sample code should be provided to guide developers in implementing and using the SDK effectively in their projects.
