TypeOfFrame

A TYPE OF FRAME classifies a VERSION FRAME. It provides a rudimentary form of metadata to describe the permitted contents of a profile (A profile validator may use such data to further check the contents of a document).

The list of frame types in EPIP is:

‘EU_PI_COMMON’: common and generic object types possibly used across multiple other frames (for example: TypeOfValue, DayType, etc.)

‘EU_PI_STOP’: all objects necessary for STOP PLACE and SITE descriptions (STOP PLACEs, QUAYs, ENTRANCEs, POINTs OF INTEREST, etc.).

‘EU_PI_NETWORK’: all objects necessary for NETWORK descriptions (LINEs, ROUTEs, JOURNEY PATTERNs, etc.).

‘EU_PI_TIMETABLE’: all objects related to timing information (VEHICLE JOURNEYs, PASSING TIMEs, etc.)

‘EU_PI_CALENDAR’: all objects related to calendars and types of day.

The ‘EU_PI_STOP’, ‘EU_PI_NETWORK’, and ‘EU_PI_TIMETABLE’ frame types carry the main “payload” data content for an EPIP exchange. The ‘EU_PI_COMMON’, and ‘EU_PI_CALENDAR’ frames types carry ancillary data referenced by the payload frames.

A CompositeFrame is a specific type of frame that contains a set of VERSION FRAMEs to which the same VALIDITY CONDITIONs have been assigned. It is in effect a grouping mechanism. The EPIP specification defines two composite frames with which to group the payload and ancillary frames:

‘EU_PI_LINE_OFFER.’ gathering all the information related to a single LINE; it shall contain ‘EU_PI_COMMON’ ‘EU_PI_STOP’, ‘EU_PI_NETWORK’, ‘EU_PI_CALENDAR’ and ‘EU_PI_TIMETABLE’. specific frames.

‘EU_PI_NETWORK_OFFER’: gathering all the information related to a single NETWORK (so multiple lines); it shall contain ‘EU_PI_COMMON,’ ‘EU_PI_CALENDAR’, ‘EU_PI_STOP’, ‘EU_PI_NETWORK’ and ‘EU_PI_TIMETABLE’ specific frames There may be multiple instances of a given frame type, for example a separate, , ‘EU_PI_NETWORK’, ‘EU_PI_TIMETABLE’ for each line.

‘EU_PI_STOP_OFFER.’ gathering all the information related to a STOPs for area; it shall contain ‘EU_PI_COMMON’ ‘EU_PI_STOP, specific frames.

One further TypeOfFrame ‘EU_PI_METADATA’ can be included in an EPIP document to provide a set of static metadata references that can be used variously by both an XML validator and a parameterised profile validator. If present, internal references can be used for the TypeOfFrameRef instances, etc; otherwise, these shall be external references that place the version number in a versionRef element.
