Only you can know what's required for your use-case.
The SP is the resource owner.
The IDP has the identities.
Most orgs will be both, some will only be SPs.

Then you're looking at the wrong examples.
The Shibboleth consortium makes implamentations for both the SP and IDP.
And MS-ADFS works in both roles simultaneously by default, IIRC.
So there's plenty of potential of confusion if you don't know what
exactly you're looking for. Certainly searching the web for generic
things like "Shibboleth" and "ADFS" will cover other cases, too.
