2. What are the main steps involved in creating a "mix" dataset?

When you are on the IUCLID opening page, you must click on the "Mixtures" insert. This is because, in the context of PCN notifications, only mixtures are declared, so the other inserts do not concern you directly.

This workspace presents you with two types of folders: "datasets" and "folders". You can navigate from one to the other using the buttons at top right. The difference between these two types is important:

• datasets" contain the editable files you will be working on;

• folders" group together the uneditable files you're about to submit; they're a snapshot of a dataset file at a given moment.

In this way, if you need to update your dataset, you'll create a new file in the "folder" containing the new information you submit.
