Is Andreas still interested in these!?

I wonder if it should instead refer users to raise a Github issue? If not, just "Aliases are not supported".

Yes. "Aliases are not supported" is sufficient. In the XMP Spec XMPSpecificationPart2.pdf it says (incomprehensibly):

Previous versions of this specification referred to aliased properties. Specific XMP implementations may treat a property in one namespace as equivalent to a property in another namespace. However, to foster interchange, applications must always write the standard, “base” form of the property. In this version of the specification, only the base properties are listed.

Alison and I visited and stayed with Andreas and family in 2016. Andreas has lost all interest in Exiv2. Time to scrub his name from the code. I have given him huge praise in the book. His implementation of the TiffVisitor is very robust and thorough.

I feel scrubbing the code prologs is something we should do towards the end of releasing Exiv2 v0.28. Possibly at RC2. I know that @piponazo would like to reformat all the code using clang based tools. While we have two shipping branches (0.27-maintenance and master) we have not done this. However if we ship v0.28 and v0.27.4 in spring 2021, there will be few subsequent changes 0.27-maintenance (if ever). We haven't had a CVE raised on Exiv2 for more than a year. There are no open security issues on Exiv2.

For that matter, all contributors names should be scrubbed. Gilles, Brad and others have credited themselves in code prologs. Author/Contributors are stored in the source code history.

I've listed the copyright notices in the code (other than "Exiv2 authors") are (and seem legitimate). As Brad, Andreas and Johannes are "Exiv2 authors", we could (but won't) modify those notes. Moreover, these three are in contrib or sample code and therefore don't impact the library. So the copyright notices seem legitimate.
