Hey, we're about to be doing this too! As far as I understand, this is what it means:
Easy ORCiD integration: have a form field for a scholar's ORCiD ID. It renders on "their page" as a link to their ORCiD profile.
Pull ORCiD integration: Populate your IR with citation records generated pulling from ORCiD (trying to avoid duplicates with existing records, etc.)
Push ORCiD integration: When you add a citation record to Islandora, it sends that info to ORCiD and populates their "Works" (publications)
