I’ve been reading up on ways to export data from Omeka S.
The documentation mentions an “output formats” module, but the following link returns a “404 not found”:
https://omeka.org/s/modules/OutputFormats/
Is that known, and what would be the current best-practice to export Omeka data entries as RDF/JSON-LD data?
Thank you very much in advance! 
You can try module Bulk Export, it does the same thing.
For json-ld, the best way is to use the api, available at url /api, it is a rest and json-ld api designed for that.
Thanks @Daniel_KM for the reply!
Indeed, the JSON-LD output of the API seems very nice and clean (to get and work with). So there’s no need for the OutputModule anymore, right?
btw: You are the author of the sparql-module, right?
On Output Formats: this was released and we published the documentation and everything, and just forgot to register it so it would show up in the modules list. The original link you posted in your first message should work now.
Note: Output Formats just adds links to get these formats more easily, but it’s just using the API; both the standard JSON-LD output and the additional formats are native features of the API.
that’s excellent news, thanks! 
Thank you for fixing the 404-link.
