A non-transitory computer-readable medium having stored thereon a plurality of sequences of instructions which, when executed by one or more processors, cause the one or more processors to perform a method of executing a code of an arbitrary application, the method comprising:

• receiving a first media file from a first media recording device;
• creating a file record for the first media file in the file table;
• determining whether the first media file belongs to an existing matter group;
• upon determining that the first media file belongs to an existing matter group:
• relating the file record with the existing matter group in the file table;
• and
• relating annotations of the first media file that are flagged to be shared, to all media files of the existing matter group;
• and
• relating annotations of all the media files of the existing matter group to the first media file;
• and
• upon determining that the first media file does not belong to an existing matter group, creating a new matter group for the first media file in the matter table of the central server.

A media recording device comprising:

• a processor;
• a network interface coupled to the processor configured to enable communications via a communication network;
• a storage device for content and programming;
• a program stored in the storage device, wherein execution of the program by the processor configures the media recording device to perform acts comprising:
• creating a first media file on the media recording device;
• receiving an event identifier for the first media file from a central server;
• and
• receiving annotations from all media files identified by the central server to be in a same matter group as the first media file.
