DFN-AAI Metadata Administration
All relevant information about the technical systems in DFN-AAI is collected here in so-called metadata. As federation operators, we regularly validate these metadata, aggregate them into our federation metadata and digitally sign them. All participating systems regularly fetch these signed federation metadata from us. Like in a telephone book, they can then look up all information about the other participants, e.g. who is participating, how the systems are reachable etc.
You - as operators of Identity Providers, Attribute Authorities, or Service Providers - maintain your systems‘ metadata on this site. You can find information on how to get access in our documentation.
