The original SENESCHAL project to create the heritagedata.org site, data, services and widgets ended way back in early 2014. In the intervening 5 years the resources have been utilized in a number of useful scenarios, and heritagedata URIs have found their way into many systems as points of reference. The vocabulary data itself has been maintained, extended and improved by members of the respective originating heritage organizations. However during this time the underlying platform actually remained fairly static. We are now performing some long overdue maintenance tasks on this platform, upgrading the underlying software and introducing an SSL certificate for https URIs (although persistent concept and scheme URIs will remain the same). We are also taking this opportunity to make some requested improvements to the web services, for example including scope notes with concepts in the returned data. There may be some slight changes required to the widget code to enable the widgets to continue functioning correctly. There will inevitably be a small amount of disruption to services during this time but we hope to keep this to a minimum.
