Cartis methodology

Infrastructure intelligence should be inspectable, not mysterious.

Cartis separates what a source reported from what has been reviewed and published. Every material value is designed to remain connected to its evidence, status and history.

Source record

What the document or dataset actually says

Assertion

The claim, value, unit and evidential context

Canonical record

The reviewed site, entity or relationship

Public view

Only information cleared for publication

Read the labels separately

Record type: Site, program, energy asset and supply agreement describe different boundaries. Energy assets and agreements do not count as physical data center sites. Known overlaps are disclosed on profiles; a site-record count is not a guarantee of unique properties.
Connected record / sourced research: These labels describe how the public record is connected to the directory. They do not certify every claim or replace claim review.
Claim review: The evidence card reports the publication review status attached to that assertion. Approval does not remove conflicts, guarantee the source is correct or make a planned project operational.
Lifecycle: Operating, construction and proposed describe development status. A facility can operate while its disclosed MW still represents design capacity rather than operating IT load.
Confidence coverage: This indicates whether a published confidence assessment is present. It is not a statistical confidence interval or a measure of completeness.
Dates: Document dates, claim dates and the record’s last update are separate. An update date is not a claim review timestamp. Missing dates remain blank; no fixed review cadence is promised.

Capacity claims are compared within their source-defined boundaries. Host campuses, phases, transaction scope, utility supply and generation are not automatically added or transferred. The evidence schedule lets you retain a dated copy and compare subsequent changes.

Research workflow

From fragmented evidence to a usable record.

The process is designed to make disagreement and uncertainty visible instead of forcing false precision.

Collect

Capture public, licensed and internally researched records without treating every source statement as fact.

Normalize

Preserve the original wording while mapping reviewed values into controlled vocabularies.

Connect

Resolve sites, participants and infrastructure to stable identities and explicit relationships.

Review

Evaluate conflicts, uncertain matches, publication readiness and material changes before promotion.

Publish

Expose only qualifying records through constrained public views while preserving internal history.

Verification standard

The record keeps the parts most databases discard.

Claim-level sourcing

Sources attach to the assertion or relationship they support, not merely to a project page.

Conflicts remain visible

Competing figures and interpretations can coexist until review resolves—or deliberately preserves—the disagreement.

History is not overwritten

Superseded claims and changed values retain their prior state and review context.

Raw values are preserved

Specialized source wording remains available even when a canonical vocabulary is blank or more general.

No inferred values

Operating capacity and other material facts are left blank when the evidence does not support a reviewed value.

Publication is controlled

Visibility and publication readiness are independently checked before records reach public views.

What a Cartis profile is

A connected view of a site and its participants
A structured record of property facts, phases, capacity and infrastructure
A timeline of sourced assertions and material developments
An explicit account of unresolved or disputed evidence

What it is not

Cartis is not a claim that every public report is correct, nor a system that hides uncertainty behind a single unexplained number. It is a framework for making evidence, judgment and change legible.
