The new registration (including COA for US PRO) is: Media type name: model Media subtype name: iges Required parameters: None Optional Parameters: None Encoding considerations: IGES is a clear text ASCII encoded format. Compression is recommended. Security considerations: None Published specification: ANS/US PRO/IPO-100 U.S. Product Data Association Trident Research Center, Suite 204 5300 International Blvd. N. Charleston, SC 29418 e-mail: uspro&scra.org Person & email address to contact for further information: Curtis Parks IGES is a commonly used format for CAD model (3-D or 2-D) interchange. An IGES file is also used for simple illustrations/figures between CAD or "drawing" applications. The latter may also be suitable for WWW vector image graphics. IGES files include parameters about the IGES object itself, e.g., version number, model size, encoded elements. The IGES Project committee has approved (3/94) the submission for registration of the format as a MIME data type. ---------------- disposition of application/iges ----------------- It is requested that the registration found at ftp://ftp.isi.edu/in-notes/iana/assignments/media-types/application/iges be marked (obsolete; replaced by model/iges), then removed after a suitable period of time. The new registration resolves the "issue noted during comment period" (see below). The change to the use of model/iges has been approved (Toronto, 11/96) by the IGES Project of the US Product Data Association. -------------------- original registration ----------------------- Date: Fri, 14 Apr 1995 10:37:01 -0500 From: parks&eeel.nist.gov (Curtis Parks) Subject: Registration of new Media Type application/iges Media type name: application Media subtype name: iges Required parameters: None Optional Parameters: None Encoding considerations: IGES is a clear text ASCII encoded format.

(This discussion was raised when registration for VRML was proposed.) The IGES Project people opined that at such time as the the requirements are resolved and new Types registered (e.g., Type CAD or Type 3D), that IGES, and perhaps other formats, may need to be considered for repositioning as subtypes of such new Media Type. However, using the above Type/Subtype and IGES viewers has demonstrated the expected functionality. []
