GSA eLibrary Contracts Data Dictionary¶

This document describes the fields available in the GSA eLibrary Contracts API endpoints (/api/gsa_elibrary_contracts/). For filtering, ordering, and pagination, see the GSA eLibrary Contracts API Reference.

Overview¶

GSA eLibrary contracts are persisted contract records from the GSA eLibrary system, representing contracts awarded under the MAS (Multiple Award Schedule) program. Tango syncs this data to provide a queryable view of MAS schedule contracts with links to IDVs and recipients.

Update Frequency¶

GSA eLibrary data is updated periodically via the sync pipeline.

Fields¶

Core identity¶

Field	Type	Description	Source
`uuid`	UUID	Tango internal identifier for this persisted record.	Tango
`schedule`	String	Schedule identifier, typically `MAS`.	GSA eLibrary
`contract_number`	String	MAS contract number (join key to IDV `piid`, best-effort).	GSA eLibrary

Party¶

Field	Type	Description	Source
`recipient`	Object \| null	Best-effort cached entity lookup by `uei` (fields: `uei`, `display_name`).	GSA eLibrary / Tango

Linked IDV (best-effort)¶

Field	Type	Description	Source
`idv`	Object \| null	Only present when the row is linked to an IDV (fields: `key`, `award_date`).	Tango

Enrichment¶

Field	Type	Description	Source
`sins`	List[String]	Special Item Numbers (SINs).	GSA eLibrary
`cooperative_purchasing`	Boolean	Cooperative Purchasing program flag (best-effort).	GSA eLibrary
`disaster_recovery_purchasing`	Boolean	Disaster Recovery Purchasing program flag (best-effort).	GSA eLibrary
`file_urls`	List[String]	Public document URLs (T&Cs, price list, catalog), best-effort merged.	GSA eLibrary

Usage Notes¶

Use uuid for API lookups. The uuid is the primary key for detail requests: GET /api/gsa_elibrary_contracts/{uuid}/.
These are GSA MAS schedule contracts. Each record represents a contract awarded under the Multiple Award Schedule program.
IDV and recipient links are best-effort. The idv expansion is populated when Tango can match the contract_number to an IDV PIID. The recipient expansion is populated via UEI lookup.
SINs connect to the MAS SINs reference table. Use sin filtering to find contracts by Special Item Number; see MAS SINs Data Dictionary.
