Hello, We would like to submit a new vendor-specific MIME type for your review. The basic idea is simple, but it did not quite fit in the IANA registration form and the recommendation was to post it to this mailing list for review. MIME media type name: application MIME subtype name: vnd.adobe.composite-asset Required parameters: final_type, final_subtype Optional parameters: none Description: This media type denotes a generic composite asset container that contains multiple sub-assets, each of which has an existing IANA registered text, image and video media types. The final type is identified by the final_type and final_subtype parameters. Sample usage: application/vnd.adobe.composite-asset; final_type=text, final_subtype=html Encoding considerations: binary This media type may require encoding on transports not capable of handling binary. Security considerations: This media type contains content that could be considered 'active' or 'executable'. However, it does not expand upon the existing security considerations already applicable to those media types. Published specification: This media type references existing IANA registered MIME types, for which there are existing specifications. Applications which use this media: Adobe Photoshop.com Web Service (http://www.photoshop.com) and its client applications. Person to contact for further information: Tapani Otala (otala@adobe.com) Intended usage: Limited Use The use of this media type is limited to the Photoshop.com web service and its client applications. Sincerely, Tapani Otala Sr. Engineering Manager, Photoshop.com Platform Services Adobe Systems Incorporated
