Function validateContainedResourceAll

Given a SolidDataset representing a Container (see isContainer), verify that all its containment claims are valid. Containment of a resource is valid if it respects slash semantics.

For the example, given a container at https://example.org/container/:

• The following resources are valid:
  • https://example.org/container/resource
  • https://example.org/container/subcontainer/
• The following resources are invalid:
  • https://example.org/container/resource/invalid (not a direct child resource)
  • https://example.org/container2 (not a child resource)
  • https://domain2.example.org/container/resource (not a direct child resource)

If a component claim is invalid, validateContainedResourceAll returns the invalid component's URL as part of its return object.

Note: It is recommended that this function always be used before calling getContainedResourceUrlAll since getContainedResourceUrlAll does not return Resources for which containment is invalid. Using the function in conjunction with getContainedResourceUrlAll allows for the detection of unexpected behaviour from servers, including malicious containment triples that could appear. Because ESS conforms to the Solid Protocol, i.e., respects slash semantics for its containment triples, validateContainedResourceAll returns true for containers fetched from ESS.
