4 BMRA External Inputs and Outputs


The outputs from BMRA which are presented to users are available in two formats - near real time broadcast of data using TIBCO messaging software and data download files available from the BMRA web site. The TIBCO type messages are available only on the High Grade Service, whereas the data files for download are obtainable from both the High Grade Service and the Low Grade Service.

The precise nature of the data available is specified in the BMRA URS. As noted in section 2.1.4, some of this data is provided via a publishing interface and it is not appropriate to include the physical structure of the screens data in this document.

Sections 4.1 to 4.3 comprise the logical definition of the data. Section 4.4 gives information on the contents of the raw data published in TIB message format from the BMRA High Grade Service, and section 4.5 gives information on the contents of the data files which are available for download from both the BMRA High Grade Service and the BMRA Low Grade Service web sites.
