# Shepherd Writeup for draft-ietf-httpbis-header-structure
## 1. Summary
Tommy Pauly is the document shepherd. Barry Leiba is the responsible Area Director.
This document defines a standard set of data types for HTTP headers and trailers, with detailed algorithms for how to serialize and parse these fields. This set of strictly-typed fields is referred to as "Structured Fields". These definitions do not apply retroactively to any existing header fields, but allow future headers to improve interoperability and consistency. Several in-progress documents rely on the format defined in Structured Fields.
## 2. Review and Consensus
This document has been an active area of discussion in the working group for over three years during its development. Many members of the working group have engaged in reviews and discussions on the mailing list, particularly due to the wide applicability of the structured field definitions that the document establishes. Several details required taking consensus calls in the past year (such as the handling of empty lists and URLs). These generated lively discussion, which did converge and reach consensus.
The working group last call was a relatively long call, about one month, during which time many detailed reviews were provided. All review comments have been incorporated.
