Metadata aggregation is performed with pyFF (currently 0.10.0dev)
Updates to crucial aggregator elements, in particular pyFF, may result in a changed format of resulting metadata aggregate. Any such change will be announced to the eduGAIN SG mailing list. If the OT observes that the update indeed introduces changes to metadata, a beta feed will be created and announced to the SG and a change on the production will be delayed by a two-week testing period. A reminder will be issued a week before the actual change of the production feed.
