App

Basics

Very simple Webview App with java ↔ javascript interface, that submits DeviceID to backend, so that Push notifications can be send.

Changes needed

Backend

• needs exta field in user-table for DeviceID (question: multiple ones?)
• Connect to google Firebase Server for sending Notifications

Frontend

check if user is in App (done by "angular.idDefined(Android)") - if so, call Android.getDeviceID() and send it to Backend.

• User service needs setDeviceID() and deleteDeviceID() fields
• Call User.setDeviceID() on login, and User.deleteDeviceID() on logout if "Android" variable is defined

Simple Trust system

Basics

- Relative in Group

- Relative in General

- Trust decreases over time

- Possibility to "Donate Trust" to other people

- Possibility for group to use Trust-System or standard admin system (like Facebook groups)

Calculation

PersonalGroup Trust

PersonalGroupInteractions(time t) + personalGeneralTrust(time t) / GENERAL_TRUST_DIVIDER * numOfGroupsJoined)

Personal Store Trust

PersonalStoreInteractions(time t) + groupTrust(time t) / (GROUP_TRUST_DIVIDER * numOfStoresInGroup)

Group Admins

isAdmin = isInTop3OfGroup || (personalGroupTrust / sumOfGroupTrust) > (sumOfGroupTrust / PeopleInGroup)
