A szöveg nyelve

1. Purpose

To describe honestly what data hangel shares publicly, what it does not share, and its relationship with open-source software.

2. Scope

hangel's public pages, aggregate figures, open endpoints and feeds; the software hangel uses and produces.

3. Principles

  1. Personal data is not open data. Data that identifies a person is not shared as open data; aggregate figures are given at a level that cannot be traced back to a person.
  2. Demo data does not count. Demo data used for presentations is not included in public figures.
  3. Organisations' public information is open. Event, listing and profile information that organisations publish themselves is visible on public pages.
  4. Respect for open source. We follow the licences of the open-source components we use and publish their list.

4. Roles and responsibilities

  • Technical lead: checks that open endpoints return only public fields.
  • Board of Directors: decides on opening any new dataset.

5. How it works at hangel today

  • Aggregate figures: A public statistics endpoint returns totals such as numbers of organisations, events and volunteering; it separates out demo data and caches results briefly.
  • Open endpoints: There are read endpoints for organisations' public events, volunteering listings and association content.
  • Feeds: An RSS feed, a news sitemap and short and long information files for AI search tools (llms.txt) are published.
  • Certificate verification: Anyone can verify a certificate code without signing in; only the necessary fields are shown.
  • Software components: A list of the open-source components used by the web app (SBOM, CycloneDX) is published at hangel.org/sbom.cdx.json with every release.
  • Source code: hangel's source code is not open source; it is kept in a private repository.

6. Not yet in place and our goals

  • No licence (for example CC BY 4.0) or data dictionary has been published for open data.
  • We do not provide impact data regularly as a downloadable dataset.
  • There is no decision to publish any part of the code as open source.

7. How to raise a concern

Errors in open data or personal data concerns: kvkk@hangel.org. Dataset requests: info@hangel.org.

8. Review

At least once a year.
