Metadata source

The eduGAIN metadata aggregate is available from eduGAIN MDS at

This metadata aggregate is expected to be consumed by participating federations, not by individual IdPs or SPs.

Metadata aggregate generation

MDS starts pulling federations metadata at half past each hour. Normally the generation process lasts up to 10 minutes. The resulting file is copied to at quarter to each hour.

Each of the federation feeds is validated and if errors are found, the feed is dropped. In such a case the latest valid copy will be used for aggregation. Should an error persist beyond the validUntil period of the copy, the data of the given federation is droped.
