I'm interpreting your comment re ADE as follows please confirm that for me.

1)I download the acsm file from the public library, using ADE, onto my desktop, in the current directory.
2) instead of using ADE to copy the acsm file to my Kobo device, I then open Calibre, to load and manage my Kobo device.

ADE doesn't put the ACSM file onto the device. It uses the details in the ACSM file to download a DRM protected copy of the book. When you connect the device, ADE will put that copy of the book on the device. It also authorises the device for your Adobe account so that the books can be read.

Borrowbox is owned by Bolinda. Overdrive is owned by Rakuten. They are both libraries of e-books, each holding a different collection. These are used by public libraries to loan e-books to clients, typically for a 3 week period. Not sure but I suspect Rakuten and Bolinda are effectively 'publishers'? Maybe other publishers use them to publish their books in e-book format for Public Library use?

"Publisher" is definitely not the correct word for Rakuten and Bolinda. They provide a service that manages the loans and downloads of the books. They are closer to a warehouse and delivery service (which I think is a terrible comparison and I'm happy for someone to correct me on ).

They appear to use the same downloaded file, an Adobe acsm file, to manage that loan, ie, which book, goes to which client, for a specific period.

The ACSM file has details of the book, the user and the time limits on the loan. Once the book is downloaded, the load details are in the book and no contact is needed to the servers. ADE and the ereaders or apps will manage that based on the information supplied. If you download the book, put it on the device, the day after the loan expires, it will not open.

Calibre is very good for managing books. But, it doesn't really work with books that have DRM. The DRM can be removed, and for purchased books, this is recommended by a lot of people. The legality and ethics of doing this is argued about frequently. For library books, it is clearer as it is not your book and DRM removal removes the time limiting factor.

I don't know if there are alternative to the Adobe acsm file and its structure downloaded from Public Libraries?

Kobo has integration with Overdrive libraries on the device. In supported countries, such as Australia, and for libraries that sign up, you can actually borrow books through the store on the device. Or if you borrow them by other methods, they will download directly to the device. But, this is only supported on newer devices. If the "Kobo Aura" you list is the original device, it does not support this. The Kobo Aura Edition 2 should have the support assuming it has a recent firmware version (OD support was originally only on the Aura ONE, but later was added to devices released after the Aura ONE). If your device supports this, there should be an option in the settings for this.

Also, I had a look for the Choice Community discussion on ereaders. I assume that is where you got the idea of the ACSM file. The details that @longinthetooth mentions in that thread are wrong in several ways. The ACSM file is used to download the book, but, after that it is not used. It is not kept by ADE.
