I'm looking for a lightweight, futureproof, private/secure solution to organizing my information. I've been looking at various projects such as Roam, Obsidian, Notion, but they're closed-source, proprietary formats. I've also looked at Emacs Org-Mode, but it's too complex.
If .rtf files could hyperlink to documents, that would be all I need. I know that they can handle attachments, but I would prefer linking in case I update the linked document. Does anyone know if this is possible?
