2 schemeProtocol-49 (ISSUE-49)

Motivated by DanC

Related Action Items:

Goals:

• review state of the art in URI schemes vs other extensibility points such as MIME types

Preparation:

• [REDACTED] 1 Oct by Craig Hockenberry:

  this very special application also shows an important aspect of iPhone development: URL schemes.

• 2 Oct: concern raised in HTTP WG:

  application uri schemes and posts on GET on the iPhone

• mnot 2 Oct raises this to the TAG:

  Looking through the TAGs findings, I think most of the relevant documents are too dense to be useful to developers like this.

• mnot again

  ...media types have a well-known limitation in that they need to be implemented server-side, which often requires coordination between the author and a server administrator. URI schemes, from the author standpoint, "just work", and arguably there are many many more authors than client application developers in the world, so it's appropriate to push the pain onto the smaller and more capable party.

  Just playing devil's advocate, you understand. If we don't pay attention to these kinds of trade-offs, we'll find the architecture roundly ignored, perhaps rightfully so.

• Eran Hammer-Lahav's msg on pownce: to HTTP WG

• For reference: we have an existing draft in this issue, though I (Dan C.) don't propose that we discuss it; URI Schemes and Web Protocols draft of 21 November 2005
