Protocol Transitioning Tiger Team (P3T)

The Protocol Transitioning Tiger Team was formed in Tucson at the Interop meeting in Nov 2023. The aim is to address the question of compatibility of the DAL protocols (and by implication protocols such as UWS) with modern web development tools. A number of people volunteered to form a tiger team to work on this.

The recommendations being examined would mostly be in DAL and GWS (e.g., TAP, SIA2, SODA, UWS) so will need to be a cross WG effort. A question to answer is : How do we adapt the protocol interactions to be compatible with tools such as OpenAPI.
