Amendment 2 - Attachment J2 - My Talking Books (RealSAM) Components v2.docx

This is a components specification attachment for the My Talking Books (RealSAM) Dialog Licenses solicitation issued by the Library of Congress (Solicitation Number 2027-NLS-0066). The document identifies all system components included within the project scope, which consists of both Library of Congress-managed services and vendor-managed services from RealThing. The Library manages the BARD Login Authentication service (based on OAuth 2.0) and the BARD service, which provides user data, catalog information, and audiobook content. Amazon manages the Alexa platform for smart speaker integration, while the My Talking Books Skill operates as an Amazon Alexa Skill for managing BARD Wishlist functionality, catalog discovery, and audiobook streaming.

RealThing Services, identified as vendor-managed, encompasses the RealSAM Dialog Engine Server, Dialog Engine License Management, RealSAM Data Services, Authentication Proxy, Webhooks, Streaming Servers, Bridge Server, RealThing.ai Infrastructure, Load Balancer, and monitoring integration with Sentry.io. This updated component list (version 2) was provided in Amendment 2 to clarify the scope of services and infrastructure required to operate the My Talking Books Smart Speaker project in production while meeting all Library of Congress IT information-system security requirements. The original proposal submission deadline was extended to September 30, 2026, and this is a sole-source procurement not open for competition.
