Results for area 6.2 Traffic information modelling methodology

term
extension compatibility
definition

ability of an extended message model instance to validate as a valid instance of core model

standard (extract)
term
mapping PIM to PSM
definition

procees allowing to derive from PIM corresponding platform specific model (PSM) represented by a schema

standard (extract)
term
XML schema definition mapping
definition

procees allowing to derive from PIM corresponding XML schema (PSM)

standard (extract)
term
(message serialization) platform
definition

a platform, allowing to represent messages in specific format according to platform specific schema (e.g. XML Schema, JSON Schema, ASN.1) and corresponding rules

standard (extract)
term
platform independent model (PIM)
definition

model of aspects of an information system (e.g. the data model) that is independent of any technical platform used to implement the model

NOTE Concrete implementations can be derived from the platform independent model by platform specific models or mappings

standard (extract)
term
platform specific model (PSM)
definition

model of aspects of an information system (e.g. the data model) that is linked to a specific technological platform (e.g. a specific programming language or data transfer syntax)

standard (extract)
term
(DATEX II model) extension rules
definition

DATEX II model extension rules ensuring, that an instance of the extended model will be compatible with core model.

standard (extract)
term
extension
definition

data model content that is not part of the DATEX II Level A model and that is added in the container package “Extension” (e.g. for project specific purposes)

standard (extract)
term
level A extension
definition

DATEX II model extension with maximum compatibility with core model without any extension

standard (extract)
term
level B extension
definition

DATEX II model extension following all extension rules. Such an extension is compatible with core model

standard (extract)
term
level C extension
definition

DATEX II model extension, which might use part of core model, but does not follow all extension rules. Such an extension is not compatible with core model

standard (extract)
term
(DATEX II) core model
definition

DATEX II model as pre-defined by a CEN/EN 16157 standard

standard (extract)
term
schema
definition

specification prescribing for given platform (e.g. XML Schema, JSON Schema, ASN.1) structures used to represent data model
