Mindlogger Backend

This repository documents setup and management of Mindlogger's Girder API backend.

Data concepts

Structures

Activities are a series of interactive screens that Users perform according to a notification schedule. Activities are bundled in Activity Sets.

Roles

These roles are defined at the Activity Set level.

Public

Anyone not logged in is Public can see things set to be publicly visible.

Owner

The creator of an Activity Set is that Activity Set's initial Owner. Each Activity Set must have at least one Owner, and ownership is shareable, separable, and transferrable. Owners can assign and remove Managers to/from their Activity Sets.

Manager

Manangers can assign/remove Editors, Managers, and Users to/from Activity Sets and can assign Viewers and Users to one another within the Activity Sets they manage.

Editor

Editors can create and edit Activities and Screens within assigned Activity Sets.

User

Users can perform all Activities in each Activity Set to which they are assigned.

Viewer

Viewers can view the responses and scores from Activities completed by the Users assigned to them, as permitted per Activity Set.

Data structure

Within Girder, data objects are Collections, Groups, and Users at the highest level. More thorough documentation and examples of the Girder structure vis-à-vis the web app interface can be found on the admin panel wiki

Collections

In the Collections, we only have the Activity Sets (currently named "Volumes") Collection.

In the Activity Sets Collection, each Activity Set has its own Folder.

Each Activity Set Folder has the following metadata.

  • metadata (Object)
    • description (string): default=""
    • members (Object)
      • editors (string Array)
        • editors[] (string): User_id of each Editor for this Activity Set
      • managers (string Array)
        • managers[] (string): User_id of each Manager for this Activity Set
      • owners (string Array)
        • owners[] (string): User_id of each Owner for this Activity Set
      • users (string Array)
        • users[] (string): User_id of each User for this Activity Set
      • viewers (Object Array)
        • viewers[].key (string): User_id of each Viewer for this Activity Set || "group/{Group_id}" for a group of Viewers for this Activity Set
        • viewers[].value (string Array)
          • viewers[].value[] (string): User_id of each User for whom the Viewer keyed here has permission to see data for this Activity Set || "folder/{Activity Set_id}" to allow the keyed Viewer to view data for all Users of this Activity Set.
    • respondent (string): default="self"
    • shortName (string): default={Activity Set name}

Each Activity Set Folder also contains an Activities Folder. That Activities Folder contains a Folder for each Activity in that Activity Set. Each of these Folders contains a Folder for each Version of that Activity (for version control). The most recent Activity Version Folder is the only version that is currently accessible through Mindlogger's interfaces, though older versions are retained for reference and future features. Each most recent Activity Version Folder has the following metadata:

  • abbreviation (string): default={Activity name}
  • description (string): default=""
  • userNotifications (Object)
    • scheduleType (Object)
      • weekly (string Array): default=[]
        • weekly[]: "Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"
      • monthly (integer Array): default=[]
        • monthly[]: 1‒28
      • calendar (Date Array): default=[]
        • calendar[]: Date Objects (time portions ignored) -userCanReset (boolean): default=false
    • timeOfDay (Object Array)
      • times (Object Array)
        • times[].key (string): "scheduled" or "random"
        • times[]scheduled.value (string): time in "HH:MM AM/PM" format
        • times[]random".value (Object):
          • random.start (string): time in "HH:MM AM/PM" format
          • random.stop (string): time in "HH:MM AM/PM" format
      • userCanReset (boolean): default=false
    • reminders (Object)
      • advanceNotification (integer): number of minutes, default=null
      • reminderDays (integer): number of days, default=null
      • userCanReset (boolean): default=false
  • screens (Object Array): the default sequence of screens
    • screens[].@id (string): API IRI suffix

Each Activity Version Folder also contains an Item for each Screen that is accessible in that Activity. The screens metadata Array lists the default sequence (if the User skips every Screen, the order in which that User would see the Screens). Each other Screen should be referenced in a nextScreen property.

When a User performs an Activtiy, each Screen will be in one of 4 Arrays as that User progresses:

  • Previously displayed
  • Currently displayed
  • Queued
  • Extra

Screens can move between adjacent Arrays conditionally but never exist in more than one Array at a time. (For a lengthy discussion of the mechanism, see #36 and #68.)

Users

  • Each User object in Girder should have a Responses Folder.

  • Within each User's Responses Folder should be an Activity Set Folder for each Activity Set to which that User is assigned. This folder should be created when a Manager assigns a User to an Activity in the admin panel, and the permissions (view rights to Users and Groups as assigned by Managers) should be updated according to changes Managers make in the admin panel.

  • Within each Activity Set Folder should be an Item for each time a User has submitted an Activity.

    • The naming convention for these Items is YYYY-MM-DD Activity Name, eg, 2018-09-25 Medications
  • Each Response Item should include at least the following as a JSON Object in the Item's metadata field:

    • If the user was notified, and if so, when.
    • If the user was reminded, and if so, when.
    • When the user completed the Activity.
    • The IRI of the Activity Version completed.
    • Device details.
    • The text (URL for web version of non-text prompts and options) of each prompt and option as presented.
    • Each selected / entered response.
    • Any user-submitted media (images / audio) should be stored in the Item for which that file is a part of.
    • Any additional configuration/settings options (eg, timer) should also be noted in the response data.
    • For example, if I answered "N/A" to EMA: Parent/Medications just a few minutes ago on my iPhone SE, the following JSON Object should be saved to my User/Responses/EMA: Parent Folder in a 2018-09-25 Medications Item's metadata Object:
      {  
        "activity":{  
          "@id":"folder/5ba515810a76ac049becd555",
          "name":"Medications"
        },
        "devices:os":"devices:iOS",
        "devices:osversion":"iOS 12.0",
        "deviceModel":"MLME22L/A",
        "responses":[  
          {  
            "questionText":{  
              "@language":"en-US",
              "@value":"What daily medications does your child take (include name and dosage)?"
            },
            "response":{  
              "textEntry":"N/A"
            }
          }
        ],
        "notificationTime":null,
        "reminderTimes":[  
      
        ],
        "responseTime":1537910311217
      }

Groups

Groups are used for 2 purposes: to associate Activity Sets with any number of Organizations for searchability and to group Viewrs to reduce overhead for Managers updating data view permissions to a group of Viewers en masse.
