About the project
About this catalogue
This unofficial site publishes a static, browseable copy of metadata harvested from Hong Kong public data sources.
What this is
The catalogue is an independent discovery layer. It preserves dataset titles, descriptions, publishers, categories, licences, and resource links as simple HTML pages, alongside small JSON and Markdown representations for software and research workflows.
Snapshot reference: 21 Oct 2026. This date is the latest represented harvest start in the local catalogue. It is a reference point, not a guarantee that every upstream record was captured at that moment.
What this is not
This is not an official government service, and it is not a live mirror. The local snapshot can mix records from complete and unfinished harvests, so it may be incomplete or differ from the current upstream catalogue. Follow a dataset’s source link when you need the latest authoritative metadata.
Dates and provenance
Each dataset’s “Harvest started” value comes from the start of the source harvest in which that package was last seen. It does not claim the precise time that individual record was fetched. A dataset’s “Updated” date is reproduced from the upstream metadata when supplied.
Documents and PDFs
This release indexes catalogue metadata and resource descriptions. It does not parse or republish the full text of linked PDF documents. PDF parsing is planned for the final v1 stage. No parsed specifications or data dictionaries are available in this build. See document availability.
Use the catalogue
Human-readable pages work without JavaScript. Search uses a static browser-side index. Start with the small text catalogue to follow paginated Markdown links. Software can also read the compact catalogue JSON, read the Markdown index, or fetch the JSON and Markdown links shown on each dataset page.
Diagnostics
The site graph is a diagnostic view of generated routes and links, not a data-resource explorer.
