Worked on the vechain/app-hub repository to deliver a new Arbor Application Manifest focused on enabling metadata-driven discovery and categorization within the app ecosystem. The approach centered on manifest file creation using JSON, incorporating structured metadata such as name, description, category, and tags to support accurate identification and improved discoverability. This work established foundational metadata standards to streamline tagging and discovery workflows, aligning with submission requirements and manifest specifications. No major bugs were reported during the development period, reflecting a focused and standards-compliant implementation. The project emphasized app development practices with attention to sustainability and readiness for onboarding within the platform.
