Make things as simple as possible(but not any simpler!)

What is SAML Metadata?

01-06-10

SAML Metadata is...● Keys and endpoint information for SAML● Signed XML (xml-dsig)● Trust derived from signature on XML

01-06-10

So what is a good way to manage this?

01-06-10

Is it a database?

A wise man said:

”Treat documents as documents”

Actually it was Ian Young :-)

01-06-10

So is it a document management system?

01-06-10

C'Mon! Please!

01-06-10

Lets take a step back and look at the interfaces

Metadata Access Interface

Storage

Access

01-06-10

● Access Interfaces alternatives● GET

– whole file download

● MDS– edugain 1.0 focuses on management

● MDX– RESTful soon-to-be Internet Draft

01-06-10

So is MDX the final word?

Lets take a stroll down memory lane...

Opinions and Experience

(my very own and on this planet...)

01-06-10

● ORM RDBMS etc suck for XML● You absolutely need revision control● We have to stop with the whole file

downloads soon● MDX is the only viable option● Metadata operators need FIPS 140-3

01-06-10

Stuff I've written over the years...

01-06-10

● saml-md-manager● ORM+RDBMS+WebUI+... #abandoned

● saml-md-tools● bash+perl+xslt+libxmlsec #works-for-me

● saml-md-aggregator● Minimal implementation of MDX● Metadata kept in git/svn/mercurial/whatever● PKCS#11 based signer● neo4j used as an index● RSN
