The SIGCAT Foundation – The Special Interest Group on CD-ROM Application and Technology
Mr. Duane Marquis
SIGCAT, Annapolis, USA
The Special Interest Group on CD-ROM Applications & Technology (SIGCAT) is a user group devoted to the investigation of CD-ROM technology and its myriad applications, and provides a forum for the exchange of ideas, information, and experiences about CD-ROM. Founded at the U.S. Geological Survey in 1986, SIGCAT is now the world's largest user group on CD-ROM technology, with over 7,000 members around the world.
SIGCAT holds bimonthly meetings where presentations are made on CD-ROM projects, with an emphasis on those applications developed by and for the Federal Government. The SIGCAT meetings also serve as a forum for discussing the latest technological develops from the CD-ROM industry. An annual conference has been held for the past three years where speakers and exhibitors from all over the country convene for four days for the purposes of sharing information and experiences on the applications and technology of CD- ROM.
Membership & Publications
Membership in SIGCAT is free and open to the general public. A bimonthly professional journal called the DISCourse ($40/yr. subscription) documents the meetings and reports on new CD-ROM developments in both the public and private sectors. The content of the DISCourse is intended to provide subscribers who cannot attend meetings with updates on all aspects of CD-ROM and conveying the experiences of those both in and out of Government who are actually using the technology.
Another publication of SIGCAT is the Bimonthly Listing of Events and Resources or the BLER. This publication is mailed free to all SIGCAT members and is intended to keep the worldwide membership informed on upcoming events, educational seminars, as well as new industry resources.
In 1991, SIGCAT was voted in as an official member council in the Federal of Government Information Processing Councils (FGIPC). Created in 1979 in response to a White House Memorandum, FGIPC is the largest intergovernmental organization representing Information Resource Management (IRM) professionals and provides leadership and support to SIGCAT and 24 other regional councils.
SIGCAT is now a non-profit foundation. As a foundation, SIGCAT will be able to continue its educational activities on a broader scale. Its executive committee is composed of Federal employees throughout a variety of agencies, all of whom have an intense interest in CD-ROM and share a common vision of the use of this technology as a key component in the Government's evolving information infrastructure.
The Fundamentals of Producing a CD-ROM
This is a hands-on seminar that describes the steps involved in creating a CD-ROM. The student will learn why CD-ROM is such a reliable and powerful publishing and archiving medium. The class will be presented with behind the scenes issues such as the ISO 9660 standard and its impact on CD-ROM design. The pros and cons of software retrieval engines will be presented for both textual and fielded data. Throughout the class, students will execute the procedures involved in creating a CD-ROM, and on the last day will leave the class with their own newly recorded CD-ROM.
This introductory workshop will provide detailed information on the authoring, premastering, and mastering of CD Recordable discs. The student will learn how CD-R can have a major impact on information distribution and data archival activities. This workshop includes hands-on experience with authoring packages and discusses compatibility issues between CD Recordable media and the various recorders on the market.
What, Why, and How of Multimedia CD-ROM
This introductory workshop is designed to help non-technical professionals and executives understand the power and potential of CD-ROM multimedia technology. The student will be guided through the maze of multimedia discs and hypermedia tools, and will learn how multimedia can be powerfully applied in business, educational, and other settings. This workshop covers the pros and cons of different platforms such as CD Assist, CD-I, DVI, CD-ROM/XA, CDTV, and MPC, the authoring tools available for each platform, and the process involved in sending data to mastering and replication facilities. The standards for both multimedia PC's and MacIntosh's will be discussed. Participants will have the opportunity for hands on experience with a variety of multimedia products.
Digital Video Workshop – Capture and Compression
This two-day intermediate-level workshop is especially designed to meet the needs of training managers, CBT, and interactive video authors, multimedia designers, and programmers. The student will learn how to capture and compress images for maximum playback quality, how and where to use "codesc" like Indeo and Cinepak, and when to consider hardware playback alternatives like MPEG or DVI. This workshop also covers which equipment to buy to accomplish these varied tasks. After this course, the participant will know how to produce high quality digital video effectively and efficiently.
SIGCAT has sponsored the development of set of guidelines for standardizing the terminology used by the myriad search and retrieval software products in the marketplace. Known as the CD-ROM Consistent Interface Committee (or CD-CINC) Guidelines, this report describes the basic functions essential to the ease-of-use of most CD-ROMs regardless of the interface and identifies general guidelines for installing and exiting CD- ROM applications. The report has been approved as a New Work Item by the National Information Standards Organization (NISO) at the National Institute of Standards and Technology (NIST).
SIGCLASS Specification for Encrypted CD-ROM
SIGCAT, through its SIGCLASS Working Group, has sponsored the development of a draft specification for encrypted CD-ROM. The purpose of this specification is to define file system extensions that will support an automated process which identifies an encrypted ISO 9660 CD-ROM and its associated cryptography. The goal is to support the application of cryptography for classified, unclassified but sensitive, commercial, and exportable CD- ROM media within an ISO 9660 conformant disc. This specification applies to all CD- ROMs that have been fully encrypted under a single cryptographic key and CD-ROMs that have individually encrypted files and/or partitions using separate keys. This specification does not identify a specific encryption algorithm or its implementation.
SIGCAT CD-ROM Compendium
In an effort to track the ever-increasing number of CD-ROM discs that contain Government data, SIGCAT established the SIGCAT CD-ROM Compendium. Originally compiled by the U.S.Geological Survey (USGS) Library, the SIGCAT Compendium is now maintained at the Government Printing Office (GPO) and is available in printed form from the GPO Superintendent of Documents. The current version of the Compendium identifies approximately 350 different CD-ROM products that are primarily based on Government data.
Copies of the SIGCAT CD-ROM Compendium cost $11.00 and can be obtained by calling (202) 783-3238 and asking for stock number 021-000-00158-9. The Compendium is also available in electronic form on the FEDWORLD BBS (703) 321-8020 or on CD-ROM (contact SIGCAT offices at (703) 435-5200).
SIGCAT also serves as an umbrella organization for a variety of specially-focused working groups which address such issues as CD-ROM in libraries, CD-ROM in education, CD-ROM in classified environments, as well as CD-ROM for the disabled. These working groups also provide expertise in technical areas such as search and retrieval software, CD- ROM standards, CD-ROM premastering, CD-ROM networking, and CD-ROM media longevity.
