If you host snapshots of web pages on your Nextcloud, this app enables any client that speaks the Memento protocol to access these snapshots.
The Memento protocol (RFC7089) is widely used to ask archives (such as the Internet Archive’s
Wayback Machine) for their copies of web pages. For example, a client (e.g. a browser extension)
may ask an archive whether it has a copy of https://nextcloud.com from around July last year, and
—if successful— will be redirected to the closest match.
Currently this app only supports snapshots that are stored as plain html files. It recognises a file as being a snapshot if the file contains a <link> to the location of the original page; such snapshots can be created using Freeze-dry.
This app requires the app Raw to also be installed, in order to host the snapshots.
The app presents a Memento TimeGate at the /timegate/{url} route.
For example, assume you have an html file example.html in the folder Documents/snapshots. If
this file contains a <link rel="origin" href="https://example.org"> in its <head>, it will be
recognised as a snapshot of https://example.org. Visiting
/apps/memento/timegate/https://example.org would then redirect you to
/apps/raw/files/Documents/snapshots/example.html (hence you need the Raw app as well).
In a typical Memento client (e.g. the Memento Time Travel browser extension), you would add your
personal archive as https://my-nextcloud/apps/memento/timegate/ (of course first replace
my-nextcloud appropriately).
A TimeMap is also exposed, at the /timemap/{url} route, to list all available snapshots of a URL.
For details, look at the documentation of the Memento protocol (RFC7089).
