Completing these very capable engines is the extensive VMETRO open recorder software libraries that utilize a common code base across all hardware and OS s providing fully maintained and consistent API s , capability , and compatibility across all VORTEX recorder , SAN and workstation connectivity products . The libraries will then be individually put behind new interface API 's on branches and then landed back on the Mozilla trunk in short intervals . This latter spanning is more than most protocols or API 's would provide , and is more of an OS-like service . Build in the direct access API 's necessary so that the user interface layer does not have to screen scrape or pretend it is a command line user . This specification will describe Java API 's designed specifically for an open and interoperable set of registry services that enable sharing of information between interested parties .
