Each entry of the dataset registers either an execution (which may have returned a result or an error) or the creation of a permalink for sharing, and contains:

• _id: the id of the interaction
• time: the timestamp of its creation
• derivationOf: the parent entry
• original: the first ancestor with secrets (always the same within an exercise)
• code: the complete code of the model (excluding the secrets defined in the original entry) (with student comments removed)
• sat: whether the command was satisfiable (counter-example found for checks), or -1 when error thrown [only for executions]
• cmd_i: the index of the executed command [only for executions]
• cmd_n: the name of the executed command [only for successful executions, i.e. no error thrown]
• cmd_c: whether the command was a check [only for successful executions, i.e. no error thrown]
• msg: the error or warning message [only for successful executions with warnings or when error thrown]
• theme: the visualisation theme [only for sharing entries]
