Looks really interesting. Could imagine someone can build a open source Notion alternative with this and offer the Recfiles as export option, would enable all types of crazy use cases. Add a read/write API and now you can have bots acting on your knowledge base. Basically MediaWiki but with a long-standing underlying format and compatibility with some unix tools already.
Does anyone have any more resources (besides the manual of course [https://www.gnu.org/software/recutils/manual ]) they can recommend about Recutils and Recfiles?
