Sample It

An interface for managing collections of labeled items and generating random subsets with specified restrictions.

User Stories

• As a maths teacher, I want to select random questions from a database, specifying that I want $2$ easy, $3$ medium and $1$ hard question in the exam. Furthermore, I could also set the number of trigonometry questions to be at least $1$ and at most $2$ . And so on.

• As a playlist maker, I would like to select some musics for a playlist with $15$ songs. From those musics, I want at least $3$ , and at most $5$ pop songs; no more than one sad song; at least $4$ electronic; and so on.

Functionality

1. List, Create, Update and Delete: Collections, Items and Labels

As an user, I would like to manage my collections, items and labels. I would like to be able to import and export them to the interface; and be able to access quickly recent edited items.

2. Random Sampling

As an user, I would like to generate random subsets from a given collection. In this raffle, I want to specify the number of items, and restrictions of the type “At least $x$ and at most $y$ items with this label.” It would be nice to be able to specify the random seed and have the option of removing the items from the database.
