Metadata for entries

[rogercreagh]

To facilitate sharing with other systems you will need to add some metadata to the daily files.

• Calendar date - currently implied by the filename and the day number in the text file, the date the entry is associated with should be available somewhere as a date field.
• Created date - the actual date the entry was created, not the calendar date (not user editable)
• Modified date - the date the entry was last modified (automatically updated on save - used to determine sync status with a CalDav server copy
• Categories (Tags) - one word text tags to group and search entries
• Status (Draft, Final, Cancelled)
• Class (Public,Private,Confidential)

There may also be more. Do you have a structured format for storing this information in the text file?
This would also all be useful info to have available in the display

RedNotebook stores data in YAML files, so it should be straightforward to add metadata.
