DESCRIPTION

To provide support for Mac OS X, radmind is aware of the Mac OS metadata used on HFS+-formatted drives. When lcreate uploads a file denoted in the transcript as an applefile (type ’a’), it encodes the file and the file’s metadata to the server as an AppleSingle file. The AppleSingle file is an archive containing a file’s relevant metadata and data in a single file stream. The radmind AppleSingle file has the following format:

1) The AppleSingle header, consisting of a 4-byte magic number, 4-byte version number, 16-byte filler, 2-byte number denoting the number of entries in the archive, and 3 header entries, each describing the items in the archive and containing a 4-byte entry id, 4-byte offset, and 4-byte length;

2) The file’s Finder information (32 bytes), which stores the file’s Type and Creator codes, as well its position in the Finder window;

3) The file’s Resource Fork, which contains things like images, sounds, and other data not easily or appropriately stored in the Data Fork;

4) The file’s Data Fork, the portion visible from the Finder, and the only part which is considered valid by flat file systems.

The radmind tool lapply similarly decodes the applefile from the server and restores it to the client Mac OS X machine running on an HFS+-formatted drive.
