Licence and credit

CC BY 4.0. Use it for anything, including commercial work, but credit Project Diaphanum (https://project-diaphanum.shreyam.me/).

SQLite databases

The same data as the Parquet tables, as SQLite 3 files (zipped), for people who prefer SQL.

File	Tables	Size	SHA-256

They contain only the rows added by Diaphanum (the ours/ data), not the earlier archive.

The whole release is mirrored on MEGA: full folder, combined, ours, sqlite.

Both folders hold the same eight tables:

Table	Rows (ours / combined)	Content
aoc_tenders	3,850,760 / 8,772,720	Published awards: organisation, value, award date, winner
aoc_details	3,850,760 / 8,391,499	Parsed award detail pages
award_bidders	11,064,270	Every bidder of those awards, with status and bid value where shown
tenders	14,987,241 / 18,939,432	Tender notices: title, organisation, value, dates, location, category
tender_details	14,987,241 / 18,165,726	Parsed notice detail pages
tender_details_extra	14,964,435	Extra notice fields
bid_lists_no_published_award	7,870,999	Bid lists of tenders whose award was not published
inferred_awards	2,928,577	One likely winner per such tender

inferred_awards is separate from the published awards and never mixed with them. Its method column says how the winner was chosen: L1 rank (1,083,948), sole financial bidder (1,745,259) or lowest price (99,370). Each row is marked "inferred from bid list; award not published". The lowest bidder does not always get the contract.

duckdb.sql("SELECT source, count(*) FROM 'hf://datasets/shreyamm/project-diaphanum/combined/aoc_tenders.parquet' GROUP BY 1").show()

State-wise tally

State and union-territory portals only. "Earlier archive" is what was already in Sarthak Siddhant's archive; "added" is what Diaphanum added. Notices are counted by the state named as the organisation. The totals below cover the state portals; the central-government rows of the earlier archive are not broken down by state, which is why they are lower than the combined row counts above.

Sources

Every record was read from an official government e-procurement portal and carries the URL of its source page. Only publicly accessible pages were used.

• NIC GePNIC state portals (about 30 states and UTs), e.g. wbtenders.gov.in, mahatenders.gov.in, etender.up.nic.in, etenders.kerala.gov.in, tntenders.gov.in.
• State-run portals: Telangana tender.telangana.gov.in, Andhra Pradesh tender.apeprocurement.gov.in, Chhattisgarh eproc.cgstate.gov.in, Bihar eproc2.bihar.gov.in, Gujarat tender.nprocure.com, Rajasthan sppp.rajasthan.gov.in (work orders, partial).
• Central Public Procurement Portal eprocure.gov.in, for the earlier archive.

Quality and limits

• Each tender appears once per table; no added row repeats a tender of the earlier archive.
• Ids from Telangana, Andhra Pradesh, Chhattisgarh and Gujarat carry the prefix TS_, AP_, CG_, GJNP_ to avoid clashes.
• Notice totals match the NIC eProcurement dashboard at about 100% per GePNIC state, except Manipur (7%) and Ladakh (97%).
• Award dates that did not parse were left blank.
• Awards are only as complete as the portals publish. In Kerala, Tripura, West Bengal, Maharashtra, Goa, Assam, Tamil Nadu, Odisha and Punjab the data holds 53-84% of the dashboard's awarded count. Tamil Nadu does not show bidders before an award.
• Rajasthan work orders are partial (about 31,500 of about 130,000). Karnataka is not included. Chhattisgarh, Gujarat and Bihar have few awards.
• Values and dates are as each portal shows them, not converted to one format or currency.
