The catalogue's own filters define coverage. Location takes an LGA from a list covering every state and territory, from Albury and Brisbane to Hobart and Darwin, typed bounding coordinates, or a box drawn on a map; beside it sit Organisation, Groups, Tags, Formats and a Date range by month. Results order by Relevance, Name Ascending, Name Descending or Last Modified, and each card shows the organisation, a description excerpt, the Dataset updated date and the formats. We slice by organisation and format so that large publishers such as Geoscience Australia Data and the Australian Ocean Data Network come out complete.
History is where Data.gov.au shows more than most catalogues. A dataset's Activity Stream lists New Package, Changed Package and Deleted Package events with the publisher account behind each change; City of Gold Coast Road Closures, which the council says is updated daily, logs a run of updates every day. Repeated runs add your own record of which datasets appeared, which resources were replaced and which were marked [INACTIVE].
Where the rows behind a record matter more than the record, such as council planning applications, we collect the resource tables and map them to one schema with the catalogue identifier on each row.
