One of our e-commerce clients has several thousand active products. As a distributor, their clients are retailers, some of which like having an up-to-date product spreadsheet.
Using the Events, Conditions, and Actions (ECA) module along with a Views Data Export view of all products, we created a view of all the relevant fields that exports a spreadsheet of all their products, and saves it in their private media system once per day.
Today, another automation using the Drupal #AI module -- automatically tag your articles.
With the AI module, its AI Automators submodule, and a provider configured, you can add an automation to any field. With a Tag field on your content, you can edit the field definition and "Enable AI Automator". Give it a reasonable prompt, and it will tag your content for you.
Like most of the AI integrations, the great thing is you can easily edit the tags later if you want to highlight something specific, or if it comes up with something inappropriate.
One of our clients is Programming Librarian, a site for librarians to plan educational programs. Programs, like many events, are often seasonal, oriented around holidays and seasonal activities.
