Find your way around the Mammoth Data Library

What the rows in the Datasets list are

Click Data in the left sidebar. The Datasets tab opens on the top level of the project. Each row is one of four kinds of item:

Columns in the Datasets list

The list loads more rows as you scroll down.

What the status chips mean

The chip in the Status column tells you the state of a dataset and of the Views built on it. Chips marked "Yes" count towards the need-attention filter.

When you expand a dataset, each View has its own chip: Failing, Out of date, Sync off or Updating. To fix these, see Control when Views update with Auto-sync.

Sort the Datasets list

Click a column header to sort by it. Click the same header again to reverse the order. The list opens sorted by Updated, newest first.

Items with no number (a folder, or a dataset still processing) always sort to the bottom. Sorting applies to the rows loaded so far.

Show only the datasets that need attention

When at least one dataset needs attention, the List settings menu (the sliders button at the right of the toolbar) has a Filter section with an item such as "3 need attention". Tick it to show only those datasets.

The count is of datasets, not Views: a dataset with three failing Views counts once. The filter turns itself off when nothing needs attention any more.

Find a dataset by name

The Datasets tab has no search box of its own. Use Search in the top bar. It searches the whole workspace, and choosing a result opens that item in the Data Library.

Change what the list shows (List settings)

Click the List settings button (sliders icon) at the right of the toolbar.

To collapse one expanded dataset, click the chevron beside it.

Your sort, density, columns and Show views choice are saved with your user preferences. The list looks the same the next time you open it, in any browser.

Select datasets, Views and folders

From the keyboard:

• the arrow keys move between rows;
• Shift plus an arrow extends the selection;
• Space ticks the focused row;
• Enter opens its panel;
• Shift+F10 (or the Menu key) opens its menu.

Act on several datasets at once

Tick two or more rows. The side panel becomes a selection panel titled, for example, "3 items selected". It lists the selection grouped under Datasets, Views, Folders and Raw files. Click the cross on a line to Remove from selection, or close the panel to clear it.

Every action waits while an item is still processing, for example "“Sales” is still processing."

Download several datasets as one file

Download opens a dialog where you choose the format:

Raw files are left out because they have no rows yet. When the file is ready it saves on its own. Limits are listed under Limits.

Every action in the More actions menu

Right-click any row, or click its ⋯ button, to see every action for that item. The menu has three bands: the main actions, then the other actions, then Move to trash in red.

A raw file cannot go to Trash, so its last item is Delete permanently. A dataset that needs a decision shows Resolve first. While an item is processing, the menu offers nothing that changes it until processing finishes.

The dataset actions are described in The dataset panel. The folder actions are in Folders and folder rules.

Add a new dataset or folder

The toolbar above the list has two buttons:

New datasets go into the folder you are in. While a dataset is being created, a placeholder row with a spinner sits at the top of the list. On a computer, the new dataset's panel opens when it arrives.

Drop files onto the list

Drag files from your computer anywhere onto the list. The upload dialog opens and takes the files, ready to upload into the current folder. See Upload files.

Start from an empty library

A project with no datasets shows "No Datasets yet" with an upload area. Drop files on it or choose them, then click Upload. Three buttons offer the other ways in: Connect to a source, Use a sample and Generate with AI.

Use the Data Library on a tablet or phone

The Datasets tab adapts to narrow screens:

On a screen under 600 px wide:

• long-press a row (or choose Select in its menu) to start selecting;
• while anything is ticked, a tap ticks or unticks;
• the + button opens New dataset and New Folder.

On a tablet or phone, a new dataset doesn't open by itself. A notice says, for example, "“Sales” just arrived." or "“Sales” is ready." with Open and Dismiss.

Who can do what in the Data Library

Anyone with access to the project can browse the list, sort and filter it, open panels and explore data. With view-only access, actions that change data are greyed out: "You have view-only access to this workspace, so you cannot add data." The selection panel says "You have view-only access to this workspace, so these actions are unavailable."
