The HTTP POST can be used to create a new resource in a container or add information to existing resources (but not remove resources or its contents) with either acl:Append or acl:Write.
As the HTTP PUT method requests to create or replace the resource state, the acl:Write access mode would be required.
As the HTTP PUT method requests to create or replace the resource state, the acl:Write access mode is required to replace an existing resource, but to create a new resource, access to the container can be either acl:Append or acl:Write.
As the processing of HTTP PATCH method requests depends on the request semantics and content, acl:Append can allow requests using SPARQL 1.1 Update’s [SPARQL11-UPDATE] INSERT DATA operation but not DELETE DATA, whereas acl:Write would allow both operations.
