The eduGAIN metadata aggregate is available from eduGAIN MDS at https://mds.edugain.org/edugain-v2.xml
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 https://mds.edugain.org 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.
The eduGAIN metadata aggregate signature may be validated with the certificate available for download here. This key was generated during a public Key Signing Ceremony held in Stockholm on 2022-03-08.
Make sure that you update to using this key and feed ASAP as the old feed will not be avaliable after 2022-07-01 00:00 UTC.
