eduGAIN metadata are available from eduGAIN MDS at http://mds.edugain.org/
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 each full hour. Normally the generation process lasts up to 10 minutes. The resulting file is copied to http://mds.edugain.org at half past 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 is signed with the the key available for download here.
