JSON File Format

From Open Rail Data Wiki
Jump to: navigation, search

The schedule data in JSON format has a single JSON record per line. The file can be parsed line-by-line to extract the data required. Each schedule file contains:

  • A header row
  • Zero or more TIPLOC records
  • Zero or more association records
  • Zero or more schedule records
  • and an end-of-file (EOF) record.

Each association and schedule record has an action - either 'create' or 'delete'. These are used in update files to add or remove records from the master schedule. Deletions will not be raised for schedules that have become historic. In full files, there will be no 'delete' records. Update files must be applied sequentially to a full file.

Record Types
