EuroFiling way forward
2004: First contacts
2005: Kick off meeting. Dimensions adopted
2006: COREP first dimensional XBRL taxonomy worldwide
2007: COREP/FINREP implemented, national extensions
2008: Matrix schema modeling
2009: Data Point Modeling
2010: Formulae implemented
2011: Common dimensions for COREP, FINREP, ECB statistics
2012: New COREP/FINREP XBRL taxonomies
2013: EBA harmonized framework go live!
COREP (≤115,000 cells): COmon REPorting , Basel II solvency ratio
FINREP (≤25,000 cells): FINancial REPorting, IFRS / CRD

… shall develop implementing technical standards to
introduce… uniform formats … regarding IT solutions.
EBA consultation paper, 2011-12-20
Reporting shall be done in accordance with the specifications
included in the Data Point Model and the XBRL taxonomies,
Data Point Model: structured formal representation of the
data, identifying all the business concepts and its relations, as
well as validation rules, oriented to all kind of implementers.

XBRL EBA Workshop – Nov ‘07
“The same information should be
produced only once”
• as such, certain elements have
been defined as common i.e. :
• Elements requested by the 3 mains
regulators (CB, CBFA, CSSF)
• Elements requested by the holding
(in the consolidated financial

statements)

DEFINITIONS
Data point = Base item [Dimension(member), Dimension(member)…]
Base item = Conceptual meaning: asset, liability, capital, exposure …
Dimension= Breakdown / Disaggregation: Country, Counterparty
Member = Each “value” of a dimension: Cash, Loans, Shares…
Asset [Type(Shares), Country(UK), Counterparty(Corporations)]
Method
If two cells in the reporting framework are disaggregations,
breakdowns, or share characteristics of the same business
concept, the differences are to be expressed as members of
dimensions.
At the end of the process, only a few of “pure” base items and a
number of dimensional members are defined to express in a
combinational structure the original regulatory framework.

Data Point Model progression
ni = number of members of the dimension i
d = number of dimensions
Total number of members ≤
∑ ni
Total number of potential data points = ∏
i=1 to d
Typically
∑ ni
i=1 to d
_
n=
∑ ni
i=1 to d
________________
d
<<
∏ ni
i=1 to d
ni
as it is equivalent to:
i=1 to d
_d
∏
n
n ≈
i
i=1 to d
and
_ _d
dn << n
17
Main Properties:
1. Arithmetic progression in the number of
members creates data points exponentially
2. Each cell defines one data point; each data
point is defined by one cell (at least).
3. Each dimension would be used only zero or
one times in each data point
4. A member would be shared among several
dimensions
5. The dimensional expression is commutative
