		| Abstract: | 
		The Virtual Observatory (VO) Registry is a comprehensive directory of
 astronomical services maintained collaboratively by major data centers
 across the globe.  Until now, the API to the Registry as used by clients
 and users relied on several outdated standards, and has interoperability
 issues with more advanced queries.  With RegTAP, there is now
 a relational schema exposed via the VO's Table Access Protocol as
 implemented by many clients, and several compliant services already
 exist.  While many users will just use UIs operating RegTAP , both
 advanced users and client authors will want to directly operate the API.
 This paper provides an overview of RegTAP. |
