0. INTRODUCTION
This specification provides the definition of the Generic
statistical message (GESMES) to be used in Electronic Data
Interchange (EDI) between trading partners involved in
administration, commerce and transport.
1. SCOPE
1.1 Functional Definition
The compilation of statistics is a continuous chain starting
with raw data collection, followed by a number of harmonization
and aggregation processes leading to aggregated statistical
data.
Raw data collection is realized by means of surveys, sampling,
direct reporting from individuals, economic operators.
Harmonization and aggregation processes are very often handled
by statistical bodies or authorized economic operators in case
of direct reporting.
A Generic Statistical Message (GESMES) is used by an
organisation involved in this elaboration process to transmit a
statistical data set.
It permits the transmission of the following, either in the
same and/or different messages:
-the statistical concepts comprising the data set and their
structure
-if required, all related information ( code sets, labels,
methodological notes, footnotes, etc.),
-the statistical figures of the data set.
This message could be used by producers and users of
statistical information such as: National Statistical Offices,
ministries, private and public administrations, private
companies etc.
1.2 Field of Application
The Generic statistical message may be used for both national
and international applications. It is based on universal
practice related to administration, commerce and transport, and
is not dependent on the type of business or industry.
1.3 Principles
The structure of statistical information to be exchanged is
quite simple and could be defined as multidimensional array or
chronological series. The difficulty of using or exchanging
statistical data comes the varieties of interpretations of
those structures. The interpretation varies from one
statistical domain to another depending on the content.
Another key factor is the volume: statistical indicators have
many dimensions (e.g. time, classifications depending on
statistical nomenclatures), dense and sparse series of matrices
could be present simultaneously for the same indicator.
The GESMES message may be used to exchange statistical data for
all statistical domains in a variety of formats together with
their descriptions.
The data in the data set (i.e. the array) is contained in a
generic segment (ARR - Array). The interpretation of the ARR
segment is provided in segment group 8. GESMES is designed to
support all types of statistical exchange, including
time-series, which can be described by means of statistical
concepts (i.e. statistical terms or objects).
Associated with statistical data are textual information
defining comprehensively the series and matrices, the
underlying statistical concept or methodology. This is often
referred to as meta-data and corresponds to associated
information which is required to interpret basic data, such as
headlines, stubs, comments and footnotes.
The acronym, GESMES, stands for Generic Statistical Message and
comprises a number of parts:
i) Identification of administrative information concerning the
interchange partners (Gr. 2)
ii) Footnotes associated with value lists, statistical concepts
and data set structures (Gr. 1)
iii) Value lists of coded or non coded items to be used in this
message or in a future message (Gr. 4)
iv) Definition of statistical concepts to be used in this
message or in a future message (Gr. 7).
v) Definition of the structure of array data to be used in this
message or in a future message, and the allocation of a unique
identity to this definition (Gr. 8).
vi) Identification of one or more data sets (Gr. 11). For each
data set: the identity of the structure definition to be used
to interpret the array data (Gr. 12); the scope, value lists or
fixed values which are local to the data set (Gr. 13 and 14);
the array data (ARR); footnotes associated with the data set
(Gr. 18, 19 and 20).
