The OCHRE Data Service facilitates the use of the Online Cultural and Historical Research Environment (OCHRE) worldwide to record, integrate, analyze, publish, and preserve cultural and historical information in all of its digital forms. Affiliated with the program of Digital Studies of Language, Culture, and History of the Humanities Division at the University of Chicago, we provide computational support for research projects in the humanities, social sciences, and beyond.
The default Start OCHRE link requires Java 8 and expects a 64-bit operating system and at least 4GB of RAM by default. It is available under Windows, Mac OS, and Linux. Note that the default Java installation is often the 32-bit version (to check, find Java in the list of System Settings > Apps and Features; 64-bit Java will be stated explicitly, otherwise it’s 32-bit). If you are using a system with a 64-bit processor (check Settings > System > About and look for System type), uninstall the 32-bit version of Java and install the 64-bit version instead. Find current Java versions to install here.
The other available Themes offer variations in the “look-and-feel” of the OCHRE interface, but have the same system requirements and provide the same functionality.
The Start OCHRE link will download a jnlp (or jsp) file which should launch Java. When launching a .jnlp file for the first time, you may need to associate this file type with “Java Web Start Launcher.” If Java Web Start Launcher is not available as an option, this suggests Java is not installed.
