The IESG has approved the following document: - 'Problem Details for HTTP APIs' (draft-ietf-appsawg-http-problem-03.txt) as Proposed Standard This document is the product of the ART Area General Applications Working Group. The IESG contact persons are Ben Campbell, Barry Leiba and Alissa Cooper. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-appsawg-http-problem/ Technical Summary This document defines a "problem detail" as a way to carry machine- readable details of errors in a HTTP response, to avoid the need to invent new error response formats for HTTP APIs. Review and Consensus The document originally appeared as an individual submission in July of 2012 and went through some evolution resulting in several revisions before being adopted by APPSAWG about a year ago. It has been largely stable since then. There has been cross-development between APPSAWG participants and W3C TAG. Development has stabilized since its WGLC, and implementations have matured with little change to the document. Perhaps noteworthy with respect to consensus is that the participants of APPSAWG cover a broad area of applications, and only some focus on HTTP work. However, that smaller group does tend to be active and thorough when they take up a work item in their specific interest area. With that in mind, consensus on the current content appears to be solid rather than rough. One of the document authors is both HTTPBIS chair and also the IETF liaison to the W3C, so there has been ample airing of this proposal on both sides of that particular fence. Personnel Murray Kucherawy is the document shepherd. Barry Leiba is the responsible Area Director.
