1 REQUIREMENT SPECIFICATION INTRODUCTION The requirement specifications concern the project Android App for Ardome at where the customer is Jonas Birmé, Unit Manager R&D. The intention is that this application will be a mobile interface to the video database. The application will have two views, a list view and an administration view. The list view will display posts representing videos with additional metadata. The view will be able to show several posts at once, load additional posts when scrolling down and be scaled to 1000 posts. There will also be a search field to search the database. The administration view will feature the ability to check and purge the deletion queue, check and cancel ongoing transfers and check the current storage status. USE CASES LIST OF ACTORS User a normal user, can only make searches and view video details Admin user a super user, can make searches, view video details, view the delete queue, view the transfers queue and view the storage status System the Android mobile application program USE CASE 1: LOG IN (MUST) User already registered The user starts the application. The user inputs username and password and presses the login button. The system queries for username and password. The system verifies the username and password. The system successfully authenticates the user. The system shows a welcome screen with text and buttons for further navigation. EXCEPTIONAL The system fails to verify the username and password. The system notifies the user that the login failed.

2 USE CASE 2: SEARCH (MUST) User logged in The user selects the search field. The user inputs a search query and starts the search. The system displays a list of titles (with keyframes) that match the search string. EXCEPTIONAL The system finds no matches to the search string. The system notifies the user that no matches were found. USE CASE 3: VIEW ASSET DETAILS (MUST) Search returned a non-empty result The user selects an item in the search results list. The system displays all video posts related to this asset, together with their associated meta-data. EXCEPTIONAL USE CASE 4: CHECK ONGOING TRANSFERS (SHOULD) The admin user selects Check Transfers in the menu. The system displays a list of ongoing transfers. EXCEPTIONAL The system finds no ongoing transfer. The system notifies the user that there are no ongoing transfers.

3 USE CASE 5: CHECK DELETION QUEUE (WOULD) The admin user selects "Check Deletion Queue" The system displays the deletion queue. EXCEPTIONAL The system finds no items in the deletion queue. The system notifies the user that the deletion queue is empty. USE CASES 6: CHECK STORAGE STATUS (SHOULD) The admin user chooses Check Storage Status The system finds erroneous servers. The system displays a list of erroneous servers and storage media and the free space. ALTERNATIVE The admin user chooses Check Storage Status The system finds no erroneous servers. The system displays Status: OK and the free space. USE CASE 7: LOG OUT (MUST) User logged in The admin user selects logout in the menu. The system disconnects the user. The system directs the user to the login view. ALTERNATIVE The admin user activates a time-out due to inactivity. The system disconnects the user. The system directs the user to the login view.

4 USE CASE 8: PURGING AN ITEM FROM THE DELETE QUEUE (WOULD) Admin user has received a non-empty delete queue The admin user selects an item and uses the purge command. The system purges the item permanently and removes it from the queue. EXCEPTIONAL USE CASE 9: UNDELETING AN ITEM FROM THE DELETE QUEUE (WOULD) Admin user has received a non-empty delete queue The admin user selects an item and uses the undelete command. The system restores the item to the main list and removes it from the queue. EXCEPTIONAL USE CASE 10: CANCELING A TRANSFER IN PROGRESS (SHOULD) Admin user has received a non-empty transfer queue The admin user selects a transfer and uses the cancel command. The system cancels the transfer and removes it from the queue. EXCEPTIONAL

5 FUNCTIONAL REQUIREMENTS These are the application's features and their associated priorites: Login for users and administrators MUST Server selection at logon MUST Search for video posts and a list view for search results MUST Navigation using touch screen buttons, the menu key and the back key MUST View asset details (all related video posts and their associated meta-data) MUST Log out MUST View storage status (admin only) SHOULD View ongoing transfers (admin only) SHOULD Cancel items in transfer queue (admin only) SHOULD View deletion queue (admin only) WOULD Purge items from deletion queue (admin only) WOULD Undelete (restore) items from deletion queue (admin only) WOULD NON-FUNCTIONAL REQUIREMENTS In addition, the application will satisfy the following requirements: Graphical user interface MUST Compatibility with Android 2.1 and later MUST Scalability for up to 1000 search results MUST Automatically resize interface to fit the screen and resolution (except for Mini) MUST Responsive interface MUST Time out due to inactivity MUST Basic error handling MUST COST REQUIREMENTS The members themselves will supply computers for development. Other costs are unknown. PRODUCTION REQUIREMENTS The application will mainly be developed at the KTH Campus in Kista and for one and a half days on site at the Vizrt Ardendo Office in Kista Science Tower. DOCUMENTATION REQUIREMENTS The Project report will be written in parallell with the actual project. At the end of the project the report will be submitted. Status reports, time reports and a project time plan will be written throughout the project The code will be documented and a javadoc will be generated A complete and comprehensive manual to the application will be written

6 GOALS The general goals of the project are: To develop a working Android application To learn how a Scrum project works in practice To learn about practical software development in a corporate environment To learn about Android development TIMELINE 20/5 - Version 1.0 done, delivery of the final code 24/5 - Oral presentation of the project
