From 0586599fc6020df996c4278230eeea99b9d070cb Mon Sep 17 00:00:00 2001 From: Lukasz Kasprzak Date: Tue, 28 Jul 2026 14:02:54 +0200 Subject: licence: relicense MIT -> AGPL-3.0-or-later lectio was MIT, which let anyone take it closed. The concern is not people selling it -- no licence stops that, and the AGPL does not try to -- but someone building a proprietary product on it and giving nothing back. Plain GPL would leave the obvious hole open: lectio-web is a network service, and hosting is not distribution, so a modified lectio-web could be run as a paid subscription API without ever publishing a line. AGPL section 13 closes exactly that. LICENSE is the verbatim FSF text. README carries the standard notice. Section 13 requires a modified network-reachable version to PROMINENTLY offer its source to the users interacting with it, so the offer ships with the code rather than living only in a file nobody fetches: - GET /source plain text, no template or config dependency, so it answers even when something else is broken - page footers every full page (fragments render inside one) - JSON envelope "source" / "license" - iCal header X-LECTIO-SOURCE / X-LECTIO-LICENSE The feed fields are not redundant: an /api/calendar.json consumer or an .ics subscriber never loads a page, so the footer alone would miss them. config.SourceURL is the single source of truth, and says in its comment that a fork running as a service must repoint it -- an offer that leads to someone else's code is not an offer. Tests pin all of it. This is a licence obligation, not a feature, so it should fail loudly if a later change drops it. --- README.md | 26 +++++++++++++++++++++++++- 1 file changed, 25 insertions(+), 1 deletion(-) (limited to 'README.md') diff --git a/README.md b/README.md index ad3d9f5..ee7b507 100644 --- a/README.md +++ b/README.md @@ -103,10 +103,16 @@ lectio --format ical --year 2026 --form new # override the form - `GET /api/calendar.json?date=…` or `?from=&to=` or `?year=` (+ optional `&form=old|new`) - `GET /calendar.ics?year=…` or `?from=&to=` — served as `text/calendar` +- `GET /source` — plain-text source offer (see [License](#license)) The web endpoints validate every input and cap a request's span at ~5 years (1830 days); JSON carries a stable `"schema": "lectio.calendar/1"`. +Both feeds also carry `source` / `license` (JSON) and `X-LECTIO-SOURCE` / +`X-LECTIO-LICENSE` (iCal), so a subscriber who never opens the HTML UI still +gets the AGPL source offer.
