MeaningGraph core concepts
Universal concepts that are not specific to any dataset (country, currency, customer, invoice, price, revenue, date, population, per capita and more), plus the meaning/draft-1 schema and format reference. Dataset graphs reuse them by address and pin a commit.

What MeaningGraph core concepts defines
A named settlement located within a country. No known values yet: city names repeat across countries, so a dataset matches a city together with its country.
One product or service entry on a commercial order or invoice, commonly with a quantity and a unit price. It does not by itself specify whether the document requests supply or…
A country or territory with an ISO 3166-1 code, identified independently of any data source. Values are keyed by the lowercase ISO 3166-1 alpha-2 code. A dataset that stores a…
An ISO 3166-1 code that identifies a country: alpha-2 ("IE"), alpha-3 ("IRL") or numeric ("372"). Each country value lists all three.
A unit of money used to express value, with an ISO 4217 code. Values are keyed by the lowercase alphabetic code. Starter subset: three currencies. No alias is a bare word or…
A person or organization that purchases goods or services.
A calendar day: year, month and day, without a time of day. A dataset that stores a timestamp whose time is always midnight can treat it as a date. Questions that ask "when",…
A person employed by an organization.
The currency in the denominator of a directed reference quote. The rate expresses quote-currency units per one unit of this currency. A model may state it as explicit context when…
The currency in the numerator of a directed reference quote. Its code identifies a currency; it does not identify a country, territory, tender validity interval or a transaction…
The calendar date to which a reference quote applies, without a time of day or time zone. It does not assert a publication, retrieval, transaction or rate-setting instant, or an…
An indicative reference observation relating two currencies in an explicit direction, for a stated reference date and under a provider's methodology. It is not a transaction…
The positive ratio of quote-currency units per one base-currency unit for an indicative reference quote. The pair direction, reference date and provider methodology are necessary…
A request for payment for goods or services supplied to a customer: what was supplied, when, where it is billed, and the amount charged. Not an order (a request to supply) and not…
One item on an invoice, with its unit price and quantity.
The amount charged on an invoice, normally the sum of its lines.
The employee that another employee reports to.
An amount of money. It is only meaningful together with its currency: its unit is one of the values of currency, so a concept that extends it states the currency as that value…
A request or commitment to supply goods or services. An order describes intended supply; an invoice requests payment for supplied goods or services, and a receipt records payment.
One product or service requested on an order.
A group with a defined identity and purpose, such as a company.
A pattern, not a number on its own: any measure for a place divided by the population of the same place, so that large and small places can be compared. It is a ratio, so it is…
An individual human being.
The number of people living in a country at a point in time. Always state the year: populations change every year and sources differ.
The amount asked for one unit of a product or service, such as the list price in a catalogue. The amount actually charged on a sale is a unit-price.
How many units of an item were sold on one line.
The money received from sales over a period, before costs. From the buyer's side the same number is spend, so a question about who buys or spends the most asks for revenue grouped…
The price charged for one unit of an item on an invoice line.
