File Format
Name Foto-Mosaic-Edda Database
Ontology
Extension(s) .dat, .idx, .fmedb
Released 2004? ("First official release")[1]

A Foto-Mosaic-Edda Database is used by Foto-Mosaic-Edda (called just "Foto-Mosaic" before a rewrite in version 5.3.0 (2009)[2]), a program by Steffen Schirmer[3] that takes a large number of images and arranges and colors them into a "mosaic" of another image, to store the constituent images. It is presumably a collection of thumbnails (of user-choosable size) of these images. It consisted of two files, one starting with ".dat" (which looks to be nothing more than a concatenation of the images) and the other with ".idx" (an index), before v. 5.3.0; afterwards, it is a single file with extension ".fmedb".

Identification

Post-5.3.0 databases start with ASCII FMEDB. Index files seem to start with the bytes 0D 4D 49 44 58 44 41 54 48 45 41 44 45 52, which is 0x0D followed by "MIDXDATAHEADER" in ASCII.
