Save mindmaps

[lolagarden]

Epic
As a user, I'd like to create mindmaps using my data and save mindmaps so I can access them again

Acceptance Criteria

• SQL database table exists to store JabMap data
• Users are able to re-access their mindmap

User Stories

Notes

Since the native FileFormat of JabRef is BibTeX, also the nodes in the mindmap should be stored as BibTeX:

@mindmapnode{node0,
  text = {...},
  cildren = {node1,node5,node2}
}
   
@mindmapnode{node1,
  test = {**markdown**},
  icons = {exlamation,note},
  bibentry = {ukl09},
  collapsed = {true}
}

• bibentry allows liking of one entry - multiple ones have to go to seperate nodes
• children: Order is stored in the array
  • no parent pointer not to duplicate information
  • BAD: parent to keep data structure lean + order has to be given as numbers
• Mindmaps flow from left to right
• Multiple root nodes could be possible -- all nodes without parent are root nodes -- mindmap selection possible
• File attachment only via BibTeX
• Future work: arrow

The SQL database is maintained by JabRef.

Rough idea:

1. JabMap sends JSON to JabRef (refs [8pt] Add (basic) REST-interface to JabRef #23 and [1pt] MindMap data model #41)
2. JabRef REST PUT endpoint replaces MindMap in the currently opened database by mindmap sent from JabMap
3. JabRef maps the JSON to a Java data structure (refs [1pt] MindMap data model #41 and [4pt] Make BibTeX to MindMap parser #38)
4. JabRef internally stores the nodes in the database associated with the currently opened mindmap (file system or database) - no action required at your side. This already has happened
