The OtsAV Media Library is a powerful, but easy to use, category system that provides full control over the categorization of your media collection. The Media Library stores information against each item, e.g. categories, rating, BPM, last play information, length, and comments.
OtsAV has its own powerful query language, Ots Media Query Language (OMQL), that enables the storage and retrieval of the Media Library contents. OMQL, coupled with the information within the Media Library, allows for limitless possibilities in categorizing and playlist generation. For details on the Ots Media Query Language click here.
The Media Library is written to disk as an Ots Media Library (.OML) file. The default OML file is, OtsAVDJ.oml, which is automatically loaded whenever your start OtsAV. It is possible to open and save other OML files, and in general to maintain more than one Media Library on the same machine, however this is usually of no advantage to most users and can result in confusion.
Note: The Media Library
filename may be different than the one shown above, dependng on
the version of OtsAV you are using.
