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/tas-accredited-building-practitioners-2017/rows. Counts and sums: https://publicdata.au/api/v1/datasets/tas-accredited-building-practitioners-2017/aggregate. - Rows: https://publicdata.au/api/v1/datasets/tas-accredited-building-practitioners-2017/rows?state=eq.TAS&limit=5 - Aggregate: https://publicdata.au/api/v1/datasets/tas-accredited-building-practitioners-2017/aggregate?group=gender&metric=count&state=eq.TAS 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/tas-accredited-building-practitioners-2017/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/tas-accredited-building-practitioners-2017/v/2017-05-11/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 Accredited building practitioners, Tasmania in Excel? Yes. https://publicdata.au/d/tas-accredited-building-practitioners-2017/v/2017-05-11/data.xlsx is a workbook with the 2,175 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/tas-accredited-building-practitioners-2017/v/2017-05-11/data.csv.gz is the CSV at about a tenth of the size. ### What years does Accredited building practitioners, Tasmania cover? The current version covers the years since 2017. Each release from Justice Tasmania becomes a new dated version here, and earlier versions stay online. ### How often is Accredited building practitioners, Tasmania updated? Justice Tasmania no longer updates it. This site checks the portal every week and adds a dated version when the file changes. ### Can I use Accredited building practitioners, Tasmania 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 Accredited building practitioners, Tasmania? No. The publisher is Department of Justice, and its page is https://data.gov.au/data/dataset/trade-licensing. This site republishes the publisher's file without changing its content. The original sits beside every version as source.xlsx with its SHA-256, so the two can be compared. ### How do I get only the rows for one state? Every version has one JSON file per value of state, 8 files in the current version, listed with row counts at https://publicdata.au/d/tas-accredited-building-practitioners-2017/v/2017-05-11/by/state/index.json. For example https://publicdata.au/d/tas-accredited-building-practitioners-2017/v/2017-05-11/by/state/tas.json holds the 1,836 rows where state is TAS. ### What is in each row? One accreditation of a building practitioner held on 10 May 2017, with the accreditation number, the practitioner's gender, suburb, state and postcode, the publisher's region code and the date the accreditation expires. A practitioner with more than one address has a row for each, under one accreditation number. ### What do the region codes mean? The publisher gives the code as a number from 1 to 4 and does not say which region each number names. In the data, 4 is on every address outside Tasmania. Hobart addresses carry 1, Launceston addresses 2, and Burnie and Devonport addresses 3. ### Is it current? No. It is a single extract from the Department of Justice occupational licensing database as at 10 May 2017, and the series is closed. The publisher's resource is named for electrical, plumbing and gas fitting licences, and its description and contents are of accredited building practitioners. Eleven rows hold only a postcode, as published. ### Does the postcode match the suburb? Often it does not, as published. None of the 45 Devonport rows carries Devonport's postcode 7310, and 8 of the 54 Launceston rows carry 7250. The suburb and the region code agree with each other, so the suburb is the better guide to where a practitioner is. ## 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.xlsx`. ## Improve this dataset This page is built from [register/tas-accredited-building-practitioners-2017.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/tas-accredited-building-practitioners-2017.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
