Maple Workbook is a file format for Maple workbooks.

It extends the functionality offered by the Maple Worksheet to allow multiple worksheets in a single file, in addition to files of other types.

Maple workbooks can contain worksheets (.mw files) as a collection of documents.  They can store variables via the savelib command, and those variables can be implicitly made available when setting libname to mention a workbook or directory containing a workbook.  Variable storage in a workbook mirrors many of the features in a library archive (.mla file).  Workbooks can also store file attachments of any kind. File attachments in a workbook can be referenced using standard maple commands for file import and manipulation via a URI.

The underlying file format is an SQLite database.
