This section
includes Best Practices and Examples
explaining how to best use this data model. It also includes
implementation
guides for a variety of the more complicated issues encountered when
designing
the standards outlined by this document. It also provides an overal
review of
the basic precepts used when developing this data model. |

Basic precepts of
this data model |
|
|
- This model was
designed
with the intent of providing all industries with a generic template
with which
to build their own data model. GS1 currently has identified 23
different
industries which participate in its standards development and
application
processes. While it is recognized that each industry has different
needs, this
model attempts to provide a flexible data model framework, which covers
what is
common across industries and upon which these industries can append
their own
unique needs.
- The data model
assumes a
base level of business transactions and agreements between buyer and
seller, which
then leads to an exchange of information deemed to be necessary for
conducting
normal business transactions. This set of information is herein called
a data
dictionary.
- This model was
developed
with the understanding that there are three different types of
attributes, as
type relates to industry:
|
|
|
- Core
– these attributes are absolutely necessary to
facilitate the accurate sharing of data sets between parties of all
industries.
The combination of these five attributes guarantees the uniqueness of
that data
set. The definition and use of these attributes is common to all
industries. In
this data model, the five core attributes are: GTIN (or alternate item
identification) of the trade item, the GLN of the information provider
(or
alternate party identification), the target market in which this data
set is
valid, a GS1 external classification value, and a system generated
product
description (see below).
Product identification as a process is mandatory. Either
a GTIN or an alternate item identification must be used. Party
identification
as a process is mandatory. Either GLN or an alternate party
identification must
be used.
- Extension
– these attributes are shared among
several industries. The definition for each attribute is agreed to by
all
industries. The determination of whether these attributes are mandatory
or
optional is made based on the business need of each industry. It is
important
to share the responsibility for maintenance of these attributes and to
maintain
a common definition across industries since the buyer receiving data
may
receive it from multiple industries. Where industries use an attribute
in
different ways, a new attribute must be developed. (e.g. size).
In addition to
mandatory/optional, when industries build their own data models from
this
generic base, they may also choose to change the other conditions
attached to
each attribute as it is relevant to their industry.
- Industry
specific
extension – these attributes are such that they are only
relevant to one
industry. The definition of these values is determined by this
industry. If a
buyer or seller does not deal in this trade item class, it is not
expected that
they build attributes related to this industry into their data model.
(e.g.
degree of wort is specifically relevant to the beer industry)

|
|
|
|
Application
notes |
|
|
The
complete data model
for an industry is made up of a combination of these three types of
attributes.
It is expected that attributes may be added or deleted from the model
in the
future.Also, as more industries become involved in the GS1 GSMP
process, it
is expected that more industry specific extensions will be created.
In most cases, the agreement reached by the two parties that will be
communicating data will include only a portion of the data model. This
is because
this model is designed to capture all possible business needs of the
industry.
In many cases, the buyer will only require a subset of these attributes
in
order to conduct business in the manner that they are accustomed

Key data
attributes |
|
|
This
data model works off a
basic principle. The entire set of data attributes assigned to a GTIN
may vary
depending on who provides the information, and in which target market
the data
is relevant. |
