This is just a quick note to let the community know how to find the latest documentation for Domino REST services (formally known as Domino Access Services).  As you probably know, each REST service is introduced in the extension library.  At any given time a subset of the services is also available in an IBM supported product (like Domino 9.0.1).  The general pattern is IBM supported services are documented in the public app dev wiki.  The remaining services (currently mail and free busy) are documented in this community only.

Here are the details:

• Core service (since Domino 9.0.1) -- http://www-10.lotus.com/ldd/ddwiki.nsf/xpAPIViewer.xsp?lookupName=IBM+Domino+Access+Services+9.0.1#action=openDocument&res_title=Core_service_reference&content=apicontent
• Data service (since Domino 8.5.3 UP1) -- http://www-10.lotus.com/ldd/ddwiki.nsf/xpAPIViewer.xsp?lookupName=IBM+Domino+Access+Services+9.0.1#action=openDocument&res_title=Domino_Data_Service_reference_dds10&content=apicontent
• Calendar service (since Domino 9.0.1) -- http://www-10.lotus.com/ldd/ddwiki.nsf/xpAPIViewer.xsp?lookupName=IBM+Domino+Access+Services+9.0.1#action=openDocument&res_title=Domino_calendar_service_reference&content=apicontent
• Mail service (extlib only) -- http://www.openntf.org/Projects/pmt.nsf/E1B347B6A993144186257AC6005577F2/%24file/Domino%20Mail%20Service.pdf
