toc protocolとは 意味・読み方・使い方

The TOC protocol, or Talk to OSCAR protocol, was a protocol used by some third-party AOL Instant Messenger clients and several clients that AOL produced itself. Sometime near August 19, 2005, AOL discontinued support for the protocol and no longer uses it in any of the instant messaging clients it actively maintains, such as its Windows and Mac clients for the AOL Instant Messenger and ICQ systems. However, it once did produce several of its own TOC clients, including TiK and TAC which are written in Tcl/Tk, TNT which is written in Emacs Lisp, all of which are open source, and a Java client originally called TIC which later became the Quick Buddy web applet. AOL also provided the TOC protocol specification openly to developers in the hopes that they will use it instead of the proprietary OSCAR protocol they use themselves. The TOC2 protocol is still supported.
