Developer resources
The source code is available using git from git://git.nordu.net/saml-md-aggregator.git.
Technology
The saml-md-aggregator is based on Spring 3. It uses a RESTful URL model and relies on the JAVA cryptography engine for key management and PKCS#11 as an interface to Hardware Security Modules (HSMs). In order to provide fast searching and lookup based on tags on metadata the saml-md-aggregator employs a graph database called neo4j. The neo4j database doesn't store critical data and is only used as an index. If things break, just delete the database and it will get re-created on next restart.
Understanding the source
Generally speaking each package under net.nordu.mdx provides a separate component of the saml-md-aggregator with sub-packages providing implementations of interfaces in the top-level packages.
