Introduction

This page describes the technical detail of data.gov.uk's harvesting of CKAN datasets into data.gov.uk. More about harvesting is described here: Harvesting Data into data.gov.uk - CKAN

Core dataset fields

Field key Value guidance Example value
name If there is a clash with an existing dataset in data.gov.uk then it will be modified to have a number suffixed, to make it unique. river-levels-sussex
title Name of the dataset. No jargon allowed - this is for general public to quickly understand what the data is about. River Levels in Sussex
notes Longer description of the data, how it was collected, etc. Recorded daily from automated monitoring stations. Recorded at midday, published by 3pm the same day. Accurate to nearest centimetre.
tags Optional. Key words/phrases that describe the subject of the data. Not displayed, but helps categorize it. ["transportation", "road safety", "accidents", "casualties"]
license_id CKAN internal id for the data's licence, from CKAN's standard list of IDs. If the license isn't in CKAN's standard list then specify (in free-text) the name of the licence in the most standard way possible. If no standard licence is used then supply the full text of the terms of use. "uk-ogl" or "OS OpenData Licence"
Ignored by DGU:
owner_org, maintainer, maintainer_email, author, author_email, relationships
The owner_org/publisher is determined by the value given in the harvester's settings, not the harvested dataset.

Resources

Field key Value guidance Example value
name Text to describe the resource. Toilet spreadsheet
date Date the resource applies to. Format: YYYY or YYYY/MM or YYYY/MM/DD. A dataset's resources should all have a date value or none should. 2014/12

It is not good enough to simply link to a page of links to the data - all the direct links to the data files must be supplied separately. https://open.barnet.gov.uk/dataset/d7384c92-5828-41a3-9d12-36d6db5c192f/resource/3e9934ac-492a-4042-971c-fe49bd9ca7e7/download/publictoiletsabfv3.0.csv
format File format. e.g. CSV, XLS, PDF, RDF, SHP, HTML, SPARQL, API. Don't mention if a file is zipped - just the format inside the zip. CSV
resource_type If it is data, then: file or api Otherwise: documentation file
schema_url URL of the machine-readable schema that the data conforms to. If it is not a standard format then leave blank. See: Appendix E - Local Authority data schemas http://schemas.opendata.esd.org.uk/publictoilets/PublicToilets.json?v=0.41
schema_type The type of schema specified in schema_url. Examples: csvlint or xsd csvlint

Local Authorities in particular should make sure they fill in the la_service, la_function, schema_type and schema_url fields.
