Attachment J2 - My Talking Books (RealSAM) Components v2.docx

This is a components specification document that details the technical architecture for the My Talking Books (RealSAM) Smart Speaker project operated by the Library of Congress. The system integrates multiple managed services and vendor-supplied components to enable audiobook access through Alexa-enabled devices. Library-managed services include BARD Login Authentication (OAuth 2.0-based) and the BARD service providing user data, catalog information, and audiobook content. The Amazon Alexa platform manages Alexa-enabled smart speaker services, while the My Talking Books Skill functions as the Amazon Alexa Skill for managing BARD Wishlist, Catalog Discovery, and Streaming Audiobooks.

The RealThing vendor manages core system infrastructure components including the RealSAM Dialog Engine Server, Dialog Engine License Management, RealSAM Data Services, Authentication Proxy, Webhooks, Streaming Servers, Bridge Server, RealThing.ai Infrastructure, and Load Balancer. System monitoring is integrated with Sentry.io for performance and security oversight. This procurement is a sole-source solicitation (2027-NLS-0066) for RealSAM Dialog licenses and related services required to operate the system in production while meeting Library of Congress IT information-system security requirements. The solicitation has undergone two amendments, with the final proposal submission deadline extended to September 30, 2026 at 5:00 PM ET. The document itself is technical in nature and serves as an appendix defining the specific components within scope rather than addressing pricing, contract vehicles, or other commercial terms.
