Dated versions never change. ## Query The query API returns only the rows you ask for, as JSON, NDJSON or CSV, from the same typed rows as the files. It needs no key. Rows: https://publicdata.au/api/v1/datasets/act-historic-marriage-index/rows. Counts and sums: https://publicdata.au/api/v1/datasets/act-historic-marriage-index/aggregate. - Rows: https://publicdata.au/api/v1/datasets/act-historic-marriage-index/rows?limit=5 - Aggregate: https://publicdata.au/api/v1/datasets/act-historic-marriage-index/aggregate?metric=count Each filter is `field=operator.value` in the query string, and every filter must match. A number or date field compares as a number or date, and a text field compares as text. Values are case-sensitive except with `ilike`. Prefix `not.` to negate a filter, as `not.eq.value`. Operators: `eq.value`, `neq.value`, `gt.value`, `gte.value`, `lt.value`, `lte.value`, `like.*text*`, `ilike.*text*`, `in.(a,b,c)`, `is.null`. - `select`: Fields to return, comma-separated. Every field when absent. - `order`: `field.asc` or `field.desc`, comma-separated. The publisher's row order when absent. - `limit`: Rows per page, 1 to 10,000. 100 when absent. - `offset`: Rows to skip. The `next` URL in each answer sets it for you. - `group`: On `aggregate`, fields to group by, comma-separated. - `metric`: On `aggregate`, `count`, `sum.field`, `avg.field`, `min.field` or `max.field`, comma-separated. `count` when absent. - `format`: `json`, `ndjson` or `csv`. JSON carries the provenance header, and the others carry it in response headers. Without a version the API answers from the newest loaded version, and that answer changes when the publisher releases again. Put `versions//` before `rows` or `aggregate` for an answer that never changes. `/api/v1/datasets//versions` lists the loaded versions. The API allows 60 requests in 10 seconds from one address. Above that it answers 429 for 10 seconds with a `Retry-After` header, a `RateLimit-Policy` header and a JSON body that gives the limit. Every API answer carries the same `RateLimit-Policy`. A client should wait the `Retry-After` seconds, or read the files, which have no limit.

Open https://publicdata.au/d/act-historic-marriage-index/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/act-historic-marriage-index/v/2026-09-27/data.csv today. The same path serves Excel, JSON, Parquet, SQLite, DuckDB, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same. ### Can I open Historic marriage index in Excel? Yes. https://publicdata.au/d/act-historic-marriage-index/v/2026-09-27/data.xlsx is a workbook with the 2,453 rows on a records sheet, the field list on a second sheet and the provenance on a third. The CSV also opens in Excel. https://publicdata.au/d/act-historic-marriage-index/v/2026-09-27/data.csv.gz is the CSV at about a tenth of the size. ### What years does Historic marriage index cover? The current version covers 1930 to 1950. Each release from Access Canberra becomes a new dated version here, and earlier versions stay online. ### How often is Historic marriage index updated? Access Canberra releases it yearly. This site checks the portal every week and adds a dated version when the file changes. ### Can I use Historic marriage index commercially? Yes. CC BY 4.0 allows commercial use, redistribution and derived works as long as the attribution is kept. The attribution string is in this page's side column and inside every file. ### Is this the official source for Historic marriage index? No. The publisher is Access Canberra, City and Environment Directorate, and its page is https://www.data.act.gov.au/d/uzaz-dbkr. This site republishes the publisher's file without changing its content. The original sits beside every version as source.csv with its SHA-256, so the two can be compared. ### What is in each row? One marriage registered in the ACT, with the registration number, the surname and given names of each party and the date of the marriage. ### Why are recent marriages missing? The publisher's index holds only marriages registered in the ACT more than 75 years ago. Later marriages are added as they pass that age. ### Is this a marriage certificate? No. It is an index with limited details. A certificate is ordered from the ACT Registry of Births, Deaths and Marriages. ## What this site did to the data Cells were typed, headers were renamed to snake_case and the encoding was made UTF-8. Rows were left alone. Nothing is derived. The publisher's file is beside every version as `source.csv`. ## Improve this dataset This page is built from [register/act-historic-marriage-index.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/act-historic-marriage-index.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
