Thursday

Web Application Security WG

Minutes
Here are some rough notes; this was an informal meeting. Many thanks to Mike West for his input on architectural issues:
  • There is scope here for creating a namespace of well-known URLs for structural destinations on the site (wider than accessibility)
  • The root of the namespace can provide the manifest
    • The manifest should point to well-known URIs, not the actual URIs—for reasons of caching and accuracy over time (and ensuring updates don't break things)
  • Content negotiation is appropriate
  • We probably don't need parameterised URIs, because these are global ones.
  • In the cases where parameterised URIs may've been used, we should consider instead links on the local page that use the @rel attribute.
  • The @rel attribute could be considered too.
    • Advantage: easier to implement
    • Disadvantage: doesn't give the overview of destinations supported by the whole site.
Next steps
  • Write the spec!
  • Run it by WebAppSec (specifically Mike, Theresa and Ricky)
  • Keep EO updated
  • Keep the people behind the proposal sent to EO updated
  • Keep Adapt updated
  • Keep a11yEdge CG updated
Agenda
  • Well-known URLs for common destinations (COGA; external proposal)
  • Discovery mechanism
Slot
