[mikkohei13]

This affects tasks #708 and #709

Form features

• How to handle project-specific data fields; i.e. anything external parties want to collect
  • Free text
  • Free text with validations
  • Enum values
  • Multimedia, or information about specific multimedia files
  • Taxa
  • Anything else?
• How to handle user data so that
  • If user is logged in, save the obs into their account
  • If user is not logged in
    • If they give email that has an account, make them login before submitting.
      • Don't lose data if user needs to recover password before logging in
    • If their email doesn't have an account
      • When user submits an observation, they don't need to register, but their contact information is stored
      • If user registers later with the same email, their observations show up under their account
      • If user wants to edit their observation, they need to register first
      • What if user has multiple emails; should we allow them to have all of them in profile, in order to link all observations to their account
      • Should we verify the email, to avoid people to submit observations using email that is not their own?
• Improve UX
  • Laji.fi login and registration, so that users don't try to register if they have existing account. Discussion at https://luomus-ict.slack.com/archives/CJKMXFDS9/p1729762476331229
  • Map interface, making it easier and more encouraging
• Privacy; set observer name as hidden by default
• Settings by URL
  • Taxon, using MX code?
  • Projects: invasive, porpoises, ring recoveries
• Existing use cases, see Create an open Vihko form (part of Luoti project) #564
• Branding etc.
  • Should this be branded as Vihko form, or separate?
  • Embedding on vieraslajit.fi - or simply link to Laji.fi instead?
• Mobile-first
• Thank you message & instructions to edit the observation later (= register to edit)
• What else?

Other features

Other features of Löydös that are needed.

• Admin interface to edit, hide and remove observations. How this should handle observations from registered vs. non-registered users?
• Migrating current Löydös observations, or keeping them in a separate collection?
