The mzIdentML format still does not fully meet the needs for some special workflows, and efforts are underway to define best practices for improving the encoding of more complex arrangements of cross-linked peptide identifications than in the 1.2 release, and to represent glycopeptide identifications in a consistent manner. This will not require a schema change, but rather, the development of best practice documents and controlled vocabulary terms will mainly define how these data types should be encoded in a consistent manner. These enhancements are expected to be completed in 2023.
