Been asking Venice:

Again ... and please answer in english: If you publish a note on NOSTR copy the content in form of a json file, delete it and then want to publish it again via uploading the json file. How do I do that and is that even possible?

Answer:

To answer your question directly: it is not possible to upload a JSON file to NOSTR to republish a deleted note.

When you publish a note on NOSTR, it is stored on the relay servers and assigned a unique ID. If you delete the note, it is removed from the relay servers and cannot be recovered.

Copying the content of the note as a JSON file before deleting it does not provide a way to re-publish the note by uploading the JSON file. NOSTR does not provide an API or functionality to upload JSON files to re-publish notes.

If you want to re-publish a deleted note, you would need to re-create the note manually by typing in the content again. Alternatively, you could consider using a note-taking or drafting tool that allows you to save and manage your notes locally, and then publish them to NOSTR when you're ready.

It's worth noting that NOSTR is a decentralized social network, and as such, it does not provide a centralized database or backup system for notes. Once a note is deleted, it is gone forever, and there is no way to recover it.
