Loading Algorithm

(proposal)

Load IIIF resource

It's a manifest

    Parse manifest

It's a collection

    A collection index has been passed

        There is a sub collection matching that index

            Load collections recursively until one containing manifests is found
            
                A manifest index has been passed (defaults to 0)

                    There is a manifest matching that index

                        Parse manifest

                    There isn't a manifest matching that index

                        Throw error

            Finished recursion and no manifests were found

                Throw error

        There isn't a sub collection matching that index

            Throw error

    A collection index hasn't been passed (undefined)

        The collection contains manifests

            A manifest index has been passed (defaults to 0)

                There is a manifest matching that index

                    Parse manifest

                There isn't a manifest matching that index

                    Throw error

        The collection doesn't contain manifests

            Load collections recursively until one containing manifests is found
            
                A manifest index has been passed (defaults to 0)

                    There is a manifest matching that index

                        Parse manifest

                    There isn't a manifest matching that index

                        Throw error

            Finished recursion and no manifests were found

                Throw error
