2 %%% File : mod_vcard.erl
3 %%% Author : Alexey Shchepin <alexey@process-one.net>
4 %%% Purpose : Vcard management in Mnesia
5 %%% Created : 2 Jan 2003 by Alexey Shchepin <alexey@process-one.net>
6 %%%
7 %%% Store vCards in mnesia to provide "XEP-0054: vcard-temp"
8 %%% and "XEP-0055: Jabber Search"
9 %%%
10 %%% Most of this is now using binaries. The search fields l* in vcard_search
11 %%% are still stored as lists to allow string prefix search using the match
12 %%% spec with a trailing element String ++ '_'.
