128 Lotus Instant Messaging/Web Conferencing (Sametime): Building Sametime-Enabled Applications
5.1 Overview of the Chat Logging SPI and DDA Toolkit
In 2001, IBM introduced the Sametime Chat Recording Service Provider
Interface (SPI), allowing developers to create Win32 DLL files to work in
conjunction with a Win32 service to capture transcripts of chats as the sessions
concluded. Corporate developers used the SPI to create custom versions of a
chat recorder facility, saving transcripts to disk, text files, relational, or Notes
databases as the company’s requirements dictated. Commercial developers
created a small number of products to do the same, with more configuration
options to serve a larger market.
With the release of Sametime 3, the SPI was subsumed into the Database and
Directory Assistance Toolkit (DDA). This chapter discusses the reasons for chat
recording, considerations for implementing chat recording, discusses a sample
available in the DDA Toolkit, and explains options for customization of the
sample. The Sametime DDA Toolkit documentation provides a breakdown of the
actual code in the sample and provides more direction for developers wishing to
customize the example using C++.
Why would we discuss chat recording in a Sametime Web development
redbook? The two subjects seem pretty distant; is not chat recording an admin
task? Let us start by examining the reasons for chat recording.
There are four primary reasons an enterprise would want to record the instant
message sessions occurring on a Sametime server:
򐂰 Regulatory compliance
򐂰 Collaborative commerce rules and workflow
򐂰 Corporate and public sector governance
򐂰 Appropriate use review
5.1.1 Regulatory compliance
In the wake of corporate scandals, document shredding, and collapsed
companies, 2003 was the year for new and extended document archiving
regulations in the United States. For years companies have been required by
various U.S. government agencies to retain paper records, and more recently
e-mail records, for specified periods of time. In March, the New York Stock
Exchange (NYSE) strongly recommended to its member companies that instant
messages be treated the same as e-mail records for retention purposes. In May,
the Securities and Exchange Commission (SEC) implemented new regulations
detailing the types of instant message conversations that by law must be retained
and archived. In July, the National Association of Securities Dealers (NASD),
