Support for Running Software Interactively using Binder

CaltechDATA is now a source of content for Binder, an open source service that allows you to interactively run software in your web browser.  Software that runs successfully on Binder will get a Binder badge on their CaltechDATA landing page like  Binder can run Python, R, and Julia code in a variety of interfaces and has extensive documentation.  Want help preparing your software?  Sign up for our workshop or ask for help by emailing data [at]  If your CaltechDATA record is ready for a Binder badge, send us an email at data [at] for approval.

Usage statistics listed in CaltechDATA

Wednesday, June 12, 2019


We now list unique views and downloads on every CaltechDATA item page.  We follow the COUNTER Code of Practice for Research Data Usage Metrics to define usage of our data files.  All usage tracking is via JavaScript using matomo, so our usage statistics definitely undercount actual usage.  Automated downloads from applications like curl or individuals who disable JavaScript manually or via an ad blocker are not included.  Research has shown this may be up to 60% of repository usage, and we hope to capture more of this usage in the future.  More info on usage statistics in CaltechDATA.
