2.1 Set-up
38
39
This example represents one, very comprehensive, method for implementing context. Other
methods may be used to implement UCM with CCTS.
40
2.2 Contextualized Hierarchy
This example identifies different types of Contextualized to meet the requirements for
Aggregate Business Information Entities (ABIEs), Association Business Information Entities
(ASBIEs), Basic Business Information Entities (BBIEs) and Business Value Domains (BVDs) as
defined in the CCTS 3.0 specification. Other types of objects also may be contextualized using
one of these types.

Definition - AssignedContextualized
46
47
An AssignedContextualized is an object to which a business context has been
assigned, using a UCM context expression.
48
49
50
The context that is assigned to an AssignedContextualized is sometime the same as its overall
context, but sometimes the assigned context is only one of the contexts that contribute to the
overall context.
51
Definition - IndependentContextualized
52
53
An IndependentContextualized is an object for which the overall context is
independent of the overall context of any other object.
54
55
The overall context of an IndependentContextualized cannot be changed by a change to the
overall context of some other object.
56
Definition - DependentContextualized
57
58
59
A DependentContextualized is an object for which the overall context is
calculated, and the calculation depends of the overall context of at least one
other object.
60
61
The overall context of a DependentContextualized can be changed by a change to the overall
context of an object on which it has a context dependency.
62
2.3 Definition - UnionContextualized
63
Definition – UnionContextualized
64
65
A UnionContextualized is an object for which the overall context is calculated
as the union of a set of ContextExpressions.
66
67
Definition - IntersectionContextualized
68
69
An IntersectionContextualized is an object for which the overall context is
calculated as the intersection of a set of ContextExpressions.

2.4 Contextualized Hierarchy Applied to CCTS BIEs
This table refers to BIE versions, rather than to BIEs. This is to emphasize that each published
version of a BIE can have a different context.

Comment
BBIE Version
AssignedContextualized,
IndependentContextualized
Each version of a BBIE has a context assigned to
it, and the overall context of the BBIE version is
just that assigned context, independent of the
context of any other BIE version.
ABIE Version
UnionContextualized
A version of an ABIE does not have a context
assigned to it. The overall context of the ABIE
version is the union of the overall contexts of
the BBIE versions and ASBIE versions within the
ABIE version.
ASBIE Version
AssignedContextualized,
IntersectionContextualized
Each version of an ASBIE has a context assigned
to it. The ASBIE version is associated with an
ABIE version. The overall context of the ASBIE
version is the intersection of the context
assigned to it and the overall context of the
ABIE version it is associated with.
73
74
75
76
2.4.1 Application of Context
Apply Context is refining the context expression of a modeled business payload. This application
of context for a specific business situation is the action of resolving a set of Contextualized
objects by applying a ContextExpression against the global set of Contextualized objects.
77
78
79
80
81
The application of context is accomplished by evaluating the simple context clauses to return a
set of Contextualized. The ContextClause is first evaluated against the ContextGraph to return a
set of ContextNodes. The set of ContextNodes is then used to query the global set of
Contextualized to return the set of all Contextualized that is assigned any of the returned
ContextValues.

2.5 Example using CCTS
In UCM, a Contextualized is anything which has a context. More specifically, a Contextualized
has a ContextExpression in terms of ContextNodes from a ContextGraph.

A BBIE (i.e. a version of a BBIE) is both an ‘AssignedContextualized’ and an
‘IndependentContextualized’. It has an assigned context, and as its context is independent of
the context of any other BIE, its overall context is just its assigned context. Some examples are:
BBIE CI_ Creditor_ Financial Institution. Austrian Bankleitzahl_ Identification.
Identifier
(assigned) context = (~AT) && ( ~Banking)
89
BBIE CI_ Creditor_ Financial Institution. German Bankleitzahl_ Identification.
Identifier

90

Identifier
(assigned) context =( ~ZA) && ( ~Banking)
91
92
93

97
98
For each of these BBIEs, the context is the intersection (“&&”) of a country and a sector
(“Banking”). The context is as assigned by a business specialist. Consider the 1st BBIE. We
know it should be associated with Austria. It also applies within Austria, since Austrian bank
numbers are used in every sub-region of Austria. However, it also applies in regions larger than
Austria, e.g. the EU when considering cross-border payments. This means that the context
combines the effects of all 3 predicates “==”, “<” and “>”. The predicate which combines all
these 3 is “~”, which means “less then, greater than or equal to”.
99
Consider now an ABIE that contains these 3 BBIEs.

An ABIE (i.e. a version on an ABIE) is a “UnionContextualized”. The context of the above ABIE is the union
of the contexts of the 3 BBIEs, i.e. the context of the ABIE is
((~AT) || (~DE) || (~ZA)) && (~Banking)
which is the union of the 3 BBIE contexts.

107
There is one other important case. Suppose some ASBIEs are created using the ABIE. An ASBIE
specializes the use of an ABIE. Two ASBIEs may be created using the same ABIE, and those two
ASBIEs have a different meaning, which means they can have different contexts. So an ASBIE
can modify the context of an ABIE.
108
109
An ASBIE (a version of an ABIE) is both an ‘AssignedContextualized’ and an
‘IntersectionContextualized’. The context of an ABIE is the intersection of its assigned context

An ASBIE effectively narrows the context of the ABIE it is associated with. Equivalently, it
effectively narrows the contexts of each of the BBIEs or ASBIEs that are contained within the
ABIE.
131
132
133
134
In this example, the same (inner) ABIE is used twice, once by each ASBIE, but the effective
contexts for the (inner) ABIE and its BBIEs are different in each case because the ASBIEs have
different assigned contexts. With the effective (inner) ABIE and BBIE contexts added (after
intersecting), the (outer) ABIE table becomes

Note how that, although the same ABIE is used twice, the effective contexts of the ABIE and the
BBIEs are different within the two different ASBIEs. For the BBIEs where the effective context is
NULL, i.e. not in any context, the BBIE is out of context (and effectively disappears).
139
140
Note that the calculated context of the outer ABIE is the union of the calculated contexts of the
two ASBIEs, i.e. it is the union (“&&”) of

and

2.5.1 Applying a Message Context
The example so far has shown context as it is assigned and calculated within a BIE library, such
an UN/CEFACT’s Core Component Library (CCL). BIEs from a library are assembled to produce
message payloads. However, the message payloads may be more general-purpose that are
required by a particular community of users. For example, a message payload designed for use

Page 16 of 20
UCM Draft A60
25 Aug 2011
153
154
through the European Union might contain more fields than are required (or appropriate) when
that message payload is used within a single country, e.g. Austria.
155
156
157
158
159
160
A general purpose message payload may be customised for a specific usage context by applying
a message context to it. An “applied context” is a context expression that is intersected with the
context of every BIE in a message payload. For every BIE, the “resultant context” of the BIE is
the intersection of the BIEs overall context and the applied context. If the resultant context of
any BIE is null, that BIE is excluded from the customised message, i.e. it is not used in the
customised message.
161
162
Suppose that the above ABIE is to be used in a message payload that is only for Austria, i.e. the
applied context is “<=AT”. Intersecting this context with the above example gives
