Hi Yves, all,
We envisioned publishing updates of LOD sources via a special LOD
resource space on the LOD endpoint.
The basic idea is to publish nested sets of updates as linked data for
years, months, days, hours, minutes, seconds.
This allows crawlers to only update resources which were recently
changed. The idea is implemented and described for Triplify at:
http://triplify.org/vocabulary/update
There is also a section on that in the paper:
Triplify - Lightweight Linked Data Publication from Relational
Databases. Proceedings of WWW 2009.
