MLA (Maple Library Archive) is a binary file format for a Maple repository.  A repository stores arbitrary Maple data including expressions, procedures, and modules.

Objects stored in in this format are stored in an Maple internal format which can be read by Maple faster than objects stored in a text-based format such as an MPL file.

MLA files are used by Maple for storing its own predefined mathematical library routines and data.

MLA files can be created, modified, or read using the LibraryTools package commands or the march command.

In Workbook files, MLA files can be created, modified, or attached using the savelib command or PackageTools package commands.
