How frequently does DataONE synchronize with Member Nodes, and will data permissions affect synchronization?

A couple people at my institution contribute data to KNB. This is harvested by you, and available through DataONE. Recently some of our metadata disappeared from DataOne and I suspect it is because the permissions on the metadata set were accidentally changed and they became private. When this happens, does it get dropped from DataONE? I am guessing you only harvest or maintain KNB metadata sets where the access permissions are public.

One of our formerly private metadata records has just been edited to allow for public read access, so I assume it will be harvested by DataONE again. How often do you harvest from member nodes?

Thanks for any information or insight you can provide.

DataONE completely respects the permissions that are set on data and metadata from Member Nodes -- so yes, if you set a data package to private, it will disappear from the public search in DataONE. That said, it is still harvested by DataONE, and if you are logged in with the appropriate accounts you could see the data set (although not through the DataONE web site -- we only show public data there for now). Harvest schedules are determined by Member Nodes, and in the case of the KNB, we ask to be harvested every three minutes. So changes should show up pretty quickly, assuming that the Coordinating Nodes are not busy harvesting some other node with a large number of changes. After you reset the permissions to public on the KNB, wait 3-5 minutes and they should show up on DataONE.

If you are interested in the harvest schedules for other Member Nodes, they are listed in our node registry: https://cn.dataone.org/cn/v1/node
