1.  Introduction

   The Internet Architecture Board (IAB) holds occasional workshops
   designed to consider long-term issues and strategies for the
   Internet, and to suggest future directions for the Internet
   architecture.  This long-term planning function of the IAB is
   complementary to the ongoing engineering efforts performed by working
   groups of the Internet Engineering Task Force (IETF).

   The IAB convened the ESCAPE Workshop to examine some proposed changes
   to the Internet and the Web, and their potential effects on the
   Internet publishing landscape.  Of particular interest was the Web
   Packaging proposal from Google, under consideration in the IETF, the
   W3C's Web Incubator Community Group (WICG), and the Web Hypertext
   Application Technology Working Group (WHATWG).

   In considering these proposals, we heard about both positive effects
   of Web Packaging and concerns that it could have significant effects
   on the relationship between publishers (e.g., news web sites) and
   content aggregators (e.g., search engines and social networks).  As
   such, our focus was primarily on this relationship, rather than
   technical discussion.

   Online publishers do not regularly participate in standards
   activities directly.  A workshop format was used to solicit input
   from them.  The workshop had 27 participants from a diverse set of
   backgrounds, including a small number of attendees from publishers,
   one aggregator (Google), plus representatives from browsers, the
