This issue can be used to track progress and discussion related to the access request and grant feature within LWS.

There is some prior art for this feature with Solid:

• SAI Access Request and Access Grant - this feature is primarily a client-side data model and interaction pattern to be used with a trusted authorization agent
• Inrupt Access Request and Access Grant - this feature is primarily a server-side data model, credential management and interaction pattern to be used with a mix of arbitrary agents and trusted agents

Some aspects to consider for this feature:

• An access grant itself should not be a security credential
• The data model for requests and grants should be simple, extensible, and rely on widely used vocabluaries
  • The data model should be independent of particular ACL layers (e.g., WAC or ACP) but it should be possible to map the data model to these ACL layers
• Any protocol-specific requirements should align with the existing LWS protocol definitions
• The feature should support both simple as well as more complex enterprise use cases.
• An access request and grant should support various types of constraints, including temporal restrictions
• This feature should integrate with LWS Notifications Feature #103
