xEvents is a JISC-funded web service to run geo-aware calendars of academic events (talks, conferences, workshops, calls for papers). It is being developed in the first instance to support the PhilEvents service, but will be made available to third parties interested in operating similar services as well. xEvents is due to be released in October 2011. The xEvents / PhilEvents project is funded by JISC as part of the JISC GEOspatial Programme.
This blog currently documents the development of xEvents and PhilEvents.
