There was some rumblings that a lot of projects don't have a DOAP file (which is processed by https://projects.apache.org) and when I looked at our description on projects.a.o it noted:
6.19.0 (2015-02-02): Latest Stable Release Which is AFAIK incorrect :-D It appears that the DOAP registration points to the SVN repository of our site publishing thing, which hasn't been in use since at last 2 February 2015, 8 years ago. This should be fixed in the projects.a.o administration to point to our DOAP file that's published on the website ( https://wicket.apache.org/doap.rdf), and I think the SCM location should also be changed from subversion to something git like. The projects.a.o site: https://projects.apache.org/project.html?wicket Any takers? Martijn
