Hi, I am working for a network which needs a pretty high standard stuff on authorities with multi hierarchical authorities and a good summary feature. We were planning to do it on head but I have a customer review on June, 29. and we fear authorities management in HEAD won't be fair enough by that time. But we still want Koha stable branches to remain stable. All the work I shall do will be on a new branch called hdl_auth. This will allow me to create two subs in Authorities called build_summary and build_hierarchy. Both will be called whenever an authority is changed and shall store datas into auth_header tables new fields. It seems to me that build a summary on the fly would be time consuming (and tümer seemed to agree to that principle) and building a hierarchy is a problem that requires many authorities_search for 1 item. So I will create a branch. I will propose you to test when development process is over. I shall have to get it work into version 3.0. Bonne journée. -- Henri-Damien LAURENT
