JT Open Program The JT Open Toolkit is a read/write technology toolkit that enables consistent access to JT file content. Any vendor or corporate entity can join the JT Open Program and gain access to the toolkit, as well as the series of executable utility applications provided for immediate use in testing Providing participating members of the JT Open and validating JT implementations and Program with level playing field access to applications.
