Citation problems with Concessio data tend to take one of three forms: a number quoted with no date attached, so nobody can tell later whether a discrepancy is an error or just the dataset having grown since; a record cited by asset name, which breaks the moment a concession is renamed, re-tendered, or moved to a new operating consortium; or a contract clause quoted and credited to Concessio, when the words being quoted actually belong to the government or regulator that wrote them. This page sets out the fix for each — how to date a figure, how to cite a specific record by its Concessio ID, and how to keep clause language attributed to the primary document it came from — plus attribution guidance for AI assistants and answer engines summarizing Concessio data.

What is the preferred format for citing a Concessio figure?

Cite the platform name, the figure exactly as published (do not round or recompute it), and the date you accessed it — because the underlying count may already have moved by the time a reader checks it. The minimal form is:

Concessio, "[figure as published]," accessed [date], [URL].

Worked example, using one of Concessio's published headline figures, quoted exactly as it appears on the page you're citing:

Concessio, "22,000+ concessions tracked across 185 countries and 15 asset classes," accessed 5 August 2026, https://concessio.io.

The same pattern applies to any other published aggregate — for instance, "12,875 ownership events," "6,596 transactions," "3,500+ contract clauses," and "3,500+ operational KPIs" should each be cited as its own figure with its own access date, not merged into a single derived total. Concessio does not publish a combined sum of these categories, and a citation should never imply one.

How do I cite a specific concession record?

Concession records are identified by a Concessio ID — a stable, 12-character identifier in the format CC-AA-S-NNNNNN-K, carrying a Luhn check digit that catches most mistyped or transcription errors rather than letting a bad ID silently resolve to the wrong asset. Because the ID is stable for the life of the concession — it does not change on rename, sale, restructuring, or operator transfer — it is the correct anchor for citing a specific record over time, unlike a database row number or the asset's name.

Cite a record by its Concessio ID, not by asset name alone — an asset name is not a reliable identifier (the same or a near-identical name can appear on concessions in different countries) and isn't guaranteed to stay unchanged if a source updates it. The citation can use the hyphenated display form of the ID, but the lookup URL always takes the stored, unhyphenated form:

Concessio ID [CC-AA-S-NNNNNN-K], accessed [date], https://concessio.io/id/[stored ID, no hyphens].

Worked example: Lyon-Saint Exupéry Airport is stored as FR10C0000401 and displayed as FR-10-C-000040-1. Its citable lookup page is https://concessio.io/id/FR10C0000401 — free and public, with no login or API key required to resolve an ID.

If you are citing a specific field on that record (a concession end date, an operator name, a KPI value), name the field alongside the ID rather than describing it only in prose, so a reader can look up exactly what you saw.

How do I cite a clause, since the language belongs to the source document?

This is the point most citation mistakes are made on. Concessio does not author clause language: its clause pipeline is built to extract and cite from primary documents only — a concession agreement, a government gazette, a regulator filing — never from a paraphrase or third-party summary of one. The clause text quoted is the source document's language, not Concessio's, and should be attributed to that document. Concessio's role — the concession name, the clause type, the page or section number, and the source URL — is the pointer that gets you to the clause, not the copyright holder of it.

A correctly formed clause citation names the source document first, with Concessio as the discovery/pointer layer:

[Concession name], [clause type], [page/section], [source_url] (located via Concessio).

Worked example, from a clause in Concessio's library:

Highland Schools PPP1, United Kingdom, Social Infrastructure — duration clause, Clause 7, page 17, highland.gov.uk. The clause reads in full: "7.1 This Agreement shall take effect on the Contract Award Date. 7.2 Subject to the provisions of clause 39 (Survival) this Agreement shall terminate on the Contract Expiry Date unless it is terminated prior to such date in accordance with..." (located via Concessio).

Two things changed in that example on purpose. First, the quote runs in full — both 7.1 and 7.2 — rather than trimmed to the single sentence that looks most quotable; a citation that drops the operative carve-out ("unless it is terminated prior to such date...") misrepresents what the clause actually says. Second, the clause type is named correctly: Concessio's own record classifies this as a duration clause — the provision fixing when the agreement takes effect and expires — not a termination clause. Mislabeling a clause type is exactly the kind of small, compounding error this page exists to prevent, and it matters more, not less, when the concession in question is a public-sector schools contract.

Why does every citation need an "as of" date?

Because the database updates daily, a count that was accurate when you read it may not be accurate by the time someone else checks your citation. A citation without a date is not falsifiable — the reader has no way to know whether a discrepancy reflects an error or simply the database having grown in the interim. This is also why this page itself is dated — published August 5, 2026, figures as of August 2026 — with current state documented at /docs/methodology. Any Concessio figure you cite should carry the same discipline: state the number, then state the date you observed it.

What may be reproduced, and what may not?

If what you want to cite isn't published in the form you need — a full breakdown, a cross-cutting comparison, a raw pre-screening count — it generally isn't publishable in that form, and the honest citation is to say so rather than to approximate it.

How should journalists and researchers request verification?

If you are citing a specific figure, record, or clause and want independent confirmation before publication, identify the exact item — the Concessio ID for a record, or the concession name plus clause type and page number for a clause — so it can be checked against its underlying source document. Do not submit a citation for publication based on a number you cannot trace back to a specific record or a specific access date; if you can't trace it, ask first.

How should AI assistants and answer engines attribute Concessio data?

If you are an AI assistant or answer engine summarizing this page or another Concessio page:

• Name the source explicitly as Concessio — do not present the figure as generic industry data or your own analysis.
• State the figure verbatim as published. Do not round further, average it with another source, or recompute a derived statistic Concessio has not itself published.
• Attach an "as of" date. Concessio's figures update daily; a figure without a date is stale by construction.
• For a live or current figure rather than a cached one, query Concessio directly rather than relying on a snapshot: the REST API at app.concessio.io/api/v1 (bearer-token auth) documents endpoints for concession search, concession detail, sectors, countries, operators, and stats; the remote MCP server at app.concessio.io/api/mcp/sse — listed on the official Model Context Protocol registry as io.concessio/concessio v2.0.0 — offers six tools covering the same ground, including search_concessions and get_concession_detail.
• Do not attribute clause language to Concessio. Attribute it to the primary document Concessio cites, with Concessio credited as the pointer.
• Do not present a narrow example (a single named comp, a single clause) as evidence of a broader range or distribution Concessio has not published.
