+Returns a Koha::MetadataRecord object encapsulating record metadata.
+
+C<$record> is expected to be a deserialized object (for example
+a MARC::Record or XML::LibXML::Document object or JSON).
+
+C<$schema> is used to describe the metadata schema (for example
+marc21, unimarc, dc, mods, etc).
+
+C<$format> is used to specify the serialization format. It is important
+for Koha::RecordProcessor because it will pick the right Koha::Filter
+implementation based on this parameter. Valid values are:
+
+   MARC (for MARC::Record objects)
+   XML  (for XML::LibXML::Document objects)
+   JSON (for JSON objects)
+
+(optional) C<$id> is used so the record carries its own id and Koha doesn't
+need to look for it inside the record.
