This section describes the numerous data feeds that acumen consumes.
POINTA CIF
A train service database (TSDB) is maintained within acumen; the TSDB is created from a full extract CIF file at initialisation, and kept up to date by consumption of an incremental update which takes place each morning at 01:00.
Both the full CIF and incremental update CIF files are obtained via SFTP directly from Network Rail PPTE (Pre-production Test Environment).
As published by ITPS, the CIF contains limited train association data (AA records) however, prior to publication to PPTE for consumption, the CIF is parsed by a service known as POINTA. POINTA is a service which infers associations and enriches the CIF file, prior to publication. Platform Occupancy INference of Train Associations POINTA is considered to be an enhancement on the association parsing and inference undertaken by WACI (or similar) components common at many locations.
