Introduction
0.1 General

General Data Point Modelling is a data oriented methodical procedure to create semantic and

multidimensional models that reflect the reporting requirements of European supervisors. Reporting

requirements are defined by regulations and represented in tables. The first Data Point Models (DPM)

were developed in 2009 to describe the data in a redundancy-free, consistent and unambiguous way.

Semantic models are used to ease the communication between domain experts and IT specialists.

Whereas formal models are defined for technical purposes, semantic models are defined from a

viewpoint of a domain user. They can contain definitions, documentations and explanations. Domain

experts decide which objects are relevant and which relations exists between the objects of the

model. Semantic models are independent of any physical implementation. The characteristic of

multidimensional models is the division of data in quantitative and qualitative aspects.

In general, the parameters that are measured in figures (also known as metrics) are quantitative

aspects that often build the basis of data analyses. Qualitative aspects provide a closer description

for these parameters. Data objects based on multidimensional models are referred to as “facts”. Fact

attributes are the quantitative aspects of a fact, and dimensions relate to the qualitative aspects of a

fact.

A Data Point Model reflects semantic and multidimensional aspects of data modelling. Data Point

Models should enhance the understanding of the data requirements for the reporting entities by

providing information on correlations that exceed the information given only by table structures.

The main challenge in data modelling is the identification of implicit information given in tables

and its transformation into a logical model. Data Point Models are typically created by specialists in

supervision who are highly skilled in understanding supervisory reporting frameworks.

This document intends to support the communication between supervisory experts and IT experts by

introducing the concept of data point modelling and its underlying terms. Data Point Models remain as

semantic models, at first technologically neutral, but they are used by IT specialists: (1) for generating

data formats for the reporting process; or (2) for designing multidimensional as well as relational

database structures for the analysis of supervisory data.

This guidance is in the form of notes in association with the pertaining requirements clause and uses

the terms “MUST” (strong recommendation), “SHOULD” (recommendation) and “MAY” (possibility).

Organizations wishing to implement this document would be expected to consider all recommendations

where the terms “MUST” and “SHOULD” are used.
0.2 Objective

A Data Point Model consists of objects that reflect the supervisory metadata and their relations among

each other that can be communicated and understood by computers. The objects of a data point model

described in this document facilitate the ease of understanding of the data structure for technicians,

and reflects the definitions, rules and constraints to be met when using a Data Point Model as the basis

for the generation of a data format, or as the basis for analytical purposes.
0.3 Target audience

This document is being created to support Information Technology (IT) experts in the transfer of

content from regulatory reporting to IT systems. It assumes that the reader has a working knowledge

of multidimensional models. Furthermore, basic knowledge about Business Intelligence is assumed for

understanding the rules to be followed when designing a multidimensional database structure for data

warehouses.

European data point methodology for supervisory
reporting
1 Scope

This document defines the Data Point Methodology for the creation of Data Point Models in the context

of European supervisory reporting. Data Point Models are published by a European supervisory

authority. To reflect the defined structures in a machine-readable form, they can be accompanied by an

XBRL taxonomy. It is also possible to extend the described methodology to other environments.

4 Data Point metamodel
4.1 General

The Data Point metamodel provides: (1) the components for the construction of a formal model that

describes sets of DataPoints relevant to European supervisory reporting frameworks; (2) definitions,

rules and constraints on how to combine these components; and (3) the meaning (semantic) of the

components and relations. Similar to a model construction kit for toys, it provides the modelling

principles with all the characteristics available for use by the modeller. A UML class diagram is used

to provide the syntax and semantic to define the metamodel for data points by showing the relevant

classes and their attributes.

4.3 Definition of the meta classes
4.3.1 DataPointModel

A DataPointModel defines structures of data describing the characteristics of the information

exchanged in the context of supervisory reporting processes. A DataPointModel consists of a dictionary

of business concepts and their properties, which are represented in tables and corresponding textual

explanation. It identifies the content of each DataPoint by its granular components with a semantic

meaning and its relation to other data points. A DataPointModel has a mandatory attribute owner who

needs to be identified.

From an IT perspective, a DataPointModel can be interpreted by IT applications which enable: (1) a

generation of data formats for the reporting process; or (2) the design of multidimensional database

structures for the analysis of supervisory data, i.e. in data warehouses.

4.3.2 PublicElement

A PublicElement is a generalization of a concept of the model. It is identified by a code and consists

of an appropriate label. PublicElements have two additional attributes giving information about the

dates of creation and modification. Each PublicElement is owned by an institution or an organization.

PublicElements are abstract and need to be specified by their concrete sub classes like Frameworks or

Tables.
References:
meta class multiplicity description

4.3.3 DictionaryElement

DictionaryElement is an abstract class of elements that build the basis of the core concepts of a

DataPointModel like DimensionedElements, Dimensions, Domains and DefinedMembers. They are

derived from PublicElements and may define a currency period to support versioning and enable a

filtering of obsolete elements by applications. The currency period is defined by two optional attributes

validFrom and validTo which should ease the maintenance of elements of the DataPointModel in the

course of time.
Superclass: PublicElement
4.3.4 Framework

A Framework is a business term common to a group of business users. It consists of reporting

regulations for a domain-specific scope of information, like COREP, FINREP or Solvency II.

Currently, the information requirements of a Framework are structured through business templates

to ease the understanding for the reporting entities that are required to submit the information to

their supervisor. A business template is a collection of supervisory data ordered in a representation

that is fitting to the business domain. On the basis of business templates, users are able to understand

the context and relationships among the required data. The business rules defined by the reporting

entities are also in the reporting regulations. Some rules are incorporated in the design of the business

templates, e.g. the detailed information which is part of a summation.

A DataPointModel can refer to one or more supervisory Frameworks. Information should be given

about which Framework the defined elements of the DataPointModel refer to.
Superclass: PublicElement
4.3.5 Table

A Table reflects the structure of a business template or represents an individual view of supervisory

data based on a specific business context. Since business templates are used for the communication

between supervisors and reporting entities, DataPoints are grouped in Tables in a DataPointModel to

reconstruct the business templates for presentational purposes.

Therefore, a DataPointModel must contain presentational information to reconstruct these defined

tables.

A Table consists of the combination of one, two or three Axes, which form TableColumns (in the

X-Axis), TableRows (in the Y-Axis), and TableSheets (in the Z-Axis). A duplication of Tables is indicated

by two or more TableSheets. Axes can be built on the basis of a set of DictionaryElements that could

already be defined in a Hierarchy. The combination of the DictionaryElements in each Axis defines a

Cartesian product which represents the set of DataPoints reflected in a Table. Tables are normalized

from a dimensional perspective, and reflect the design constraint that a DictionaryElement can only be

associated with one Axis.

Superclass: PublicElement
4.3.6 TableGroup

A TableGroup is a set of Tables that represents a business template. A TableGroup is created when a

business template defines more than one table to reflect the business context. A TableGroup also needs

to be created when the business template refers to the same dimension-member combinations in more

than one axis. The business template is to be split into two or more Tables to prevent that the same

Dimension is associated with a DataPoint more than once.
Superclass: PublicElement
4.3.7 Hierarchy

Members as well as DimensionedElements can be arranged in Hierarchies to represent the relationships

to one another. In mathematical terms, a Hierarchy is a rooted tree that provides the information if a

Member is at the top level, below another Member, or at the same level. Financial information is often

split up into different segmental breakdowns, which represent Dimensions in multidimensional terms.

If the Members of a Dimension share the same level of detail, they could be represented as a flat list.

But often the Members relate to each other, i.e. in a parent-child relationship, and so they form natural

hierarchies. The information about the location of a Member in a Hierarchy of a Dimension improves its

understanding. Furthermore, Hierarchies can be used to define rules for calculations or aggregations. In

the DataPointModel, a Hierarchy forms a set of DefinedMembers of an EnumerableDimension arranged

in a hierarchical disposition.
Superclass: PublicElement
4.3.8 Taxonomy

A Taxonomy combines the components for a version of the DataPointModel for a given period of time.

Its currency period is defined by the attributes validFrom and validTo. By creating a relation between

Taxonomy and DictionaryElements, Tables and Hierarchies, a set of valid DataPointModel components

are being created. PublicElements like Table and Hierarchy can be reused when they have not been

modified since the last Taxonomy version.
Superclass: PublicElement
4.3.9 Module

A Module is a group of DataCubes that carry related semantics and may serve the reporting process.

Modules define sets of business information that should be reported together, i.e. to conduct validation

rules that are defined across DataCubes.
