A free to use, web based system, to allow lookup and comparison of standard data flows in the UK electricity system.  The Data Transfer Catalogue is managed and maintained by Gemserv on behalf of MRASCo and is updated and issued to participants and interested parties on a twice yearly basis.  The Lerryn DTC viewer allows users to quickly find and select the flows or data items listed in the DTC and then view their structure and content. This tool has several search facilities including a "where used" function that lists all flows which use a specific data item.
