If you have use-cases for new SCHAC attributes or you would like to suggest changes to the current SCHAC attributes, the best way to do that is to send emails to the SCHAC community REFEDS mailing list.
Proposals for changes are discussed on the SCHAC mailing list for community feedback and approved by the SCHAC Editorial Board. If consensus is reached on a proposed change, then the new attributes or the updated attributes are added to the SCHAC schema on the next new release.
...
The group is open to anybody who has experience using directories, attribute schemata and who is keen to contribute.
