Hi Erich, Taking out the Package information from ODA is not trivial and it will break a lot of database functionalities in OSCAR because many ODA subroutines use the Packages table and its primary key, package_id. Eventually in order to take out the Packages information from ODA, we need to change many parts of the ODA schema. I don't think it can be done in a very short time period.
Instead, I would like to keep the ODA stuff as it is for now. Having the package information in ODA does not hurt OSCAR at all and it won't affect what we want to implement on Select as long as we do not forget to use the opkg meta data on Selector. Basically this is what I am doing and will. More importantly, Selector is heavily using the "Node_Package_Status" table containing the primary key (package_id) of the "Packages" table. We can not simply make another stuff to replace what the Node_Package_Status table does now. I still have a strong feeling that we need to use the "Node_Package_Status" whether we keep the Package information (which comes from config.xml of all the OSCAR packages) in ODA or not. So for the short time period, I would like to make ODA work as it does and just we use it for "Node_Package_Status" on Selector. For the long term, I may want to change the ODA schema to reduce the fields of the "Packages" table and remove its weak entity group (Packages_requires, Packages_provides, Packages_conflicts, and so on) but I still need to keep its strong relation tables (Group_Packages, Node_Package_Status, Image_Package_Status) as it is. But I still believe that having the full package information in the "Packages" table does not hurt OSCAR and it will be just redundant to the opkg meta data. Why don't we just make ODA run as it is and not use it for the "Packages" table related queries as much as possible? This way, we will not break the OSCAR source codes terribly. Once we are not using the ODA "Packages" table any more and we feel that everything is ready for using only opkg meta data for the package information instead of oda, then let's decide what we want to do with the "Packages" table and more stuffs in ODA.
