I need to setup a continental geoportal, that would be based on a series of geonetwork servers disseminated in the continent (about 6 servers).
In the geonetwork documentation, http://nationaalgeoregister.nl/geonetwork/docs/eng/users/admin/harvesting/index.html They give an example of a hierarchical harvesting: C harvest B, B harvests A, D harvest C, B and A. According to the documentation, there is no problem due to the UUID.
In my case, the harvesting would be circular: say we have S1, S2, S3, S4, S5, S6, then S1 harvests S2, S3, S4, S5, S6; S2 harvests S1, S3, S4, S5, S6, etc. So the user can interrogate the closest geoserver, and get information for the whole continent.
Will this kind of circular approach work, or shall I fall back to a hierarchy?
