Index of CF Trac Tickets
This page is an archive copy of the former CF Metadata Trac site, which is no longer active. The Trac site was used until July 2018 for discussion of enhancements to the CF convention. New proposals are now discussed in GitHub.
For historical interest, information about how the former CF Metadata Trac site was set up and used can be found here.
This index is a static HTML page copied and edited from the output of a Trac query. The index and archive of tickets have been edited to remove #120-#122 and #124-#137 because these were spam.
