I think you need a Zettelkasten, but its data collection from all your sources may be challenging if not an overkill... However, a Zettelkasten stores metadata, which can include tags, subject headings, and unique identifiers that help link and organize notes. This metadata enhances the ability to retrieve and connect related information within the system; not sure how to do so externally.

The key is to store both data and metadata... OpenMetadata may be what you need: https://open-metadata.org/ but I couldn't spot wiki, chat, github nor JIRA connectors :shrug:

Good luck, keep us posted.
