General Principles
 Internet standards-based application : HTTP, SMTP, S/MIME
 ‘Thin client’ architecture : only browser at client side, no NBB




software
NBB does not intervene in the automation at client side
One central validation-server at the NBB
Support different profiles of users : low-profile, semi-automated and
full-automated
Support different levels of security : 'strong' and 'weak' secured
Client is responsible for follow-up and quality of his reporting
 Immediate validation of his reporting
 Adequate functions to do this follow-up
 Same philosophy for many reportings
General Principles
 Reporting agents receives their own 'space' on the server
 input for a survey can be done over several days
 to finish the reporting, they have to 'close' the questionnaire
 Multilingual application
 Business areas are responsible for the business logic
 software is managed by the business areas
 the application contains functions to define new surveys, forms,
validation- and derivation rules without intervention of the IT-department
 Short 'time to market' for new questionnaire
Input Channels
 On-line data entry : 'Web-forms'
 Layout and content of Webform is determined by end-users
 Import of CSV-files
 Synchronous or asynchronous treatment
 Format of the csv-file is similar to the corresponding Web-form
 Http file upload
 XML format, one or many 'tables'
 Asynchronous treatment
 Client gets a validation report via e-mail
 Mail exchange
 Strong secured : data is encrypted and digitally signed (S/MIME)
 For certain reportings, non-secure mail is authorised under the
responsibility of the client. Control on the 'from address'
Input Channels
 XBRL (IFRS, Bazel II, FINREP)
 integrated in the content part of our proprietary XML format
Advantages for the reporting agent
 Advantages for the reporting agent
 A single tool
 A single address
 A single userID/certificate
 A single interface
 Multilingual software
 No software, no installation, no costs
 No interference between CSSR and the internal organisation of the
reporting agent
 Validation reports (on-line or off-line)
Advantages for the central Bank or the Supervisor
 A single IT software
 No software distribution
 No support - officially only one browser supported (I.E. v 5.0)
 New release on demand & when needed
 Savings on costs of data entry, time to produce the results
 Higher quality thanks to integrated checks
 Software fully managed by the statisticians
 Reducing the "time to market"
IT: Functionalities for the reporting agent
 Web page interface with forms
 Edit, Save, Delete, Validate functions
 File upload
 On-line validation
 On-line totalisation
 Standard print of forms
 Private memory space to store temporary data
 Identification of the contact persons
 Delegation of access authorisation
 Follow-up tool (control board)
 E-mail upload and off-line validation report
Functionalities for the statisticians & the supervisors
 Domain definition
 Survey definition
 Code table, classification & list definition (meta-data)
 Definition, maintenance & update of validation & calculation rules
 Population Management
 Which companies have to report what for which period within which
prescribed time limit
 Follow-up of response
 calculation of response rate / non-response rate / average delay for
reporting
 preparation of reminder

XBRL and the CSSR
 There
are no limitations in the reporting
protocol with regard to:
 the number of referenced taxonomies (templates);
 the number of facts, contexts or periods.
 So,
within one document it is possible to report:
 facts for all taxonomies for one period.
 facts for one / more taxonomies for several periods.
 (very) limited sets of concepts, possibly even
concept per concept, for corrections or revisions.

 Consultation

 How
to create a table visualisation?
 Choose Y-axis
 Choose one (or more) X-axis
 Create 0,1,... drop-down boxes

CSSR - business rules
 Calculation
linkbase:
 only straightforward, simple calculations
 No
inequalities.
 No multiplications.
 No exceptions.
 No cross-context.
 Formula
linkbase no recommendation yet
 IT: additional rules outside taxonomy
© National Bank of Belgium
CSSR - business rules

Business rules outside of taxonomy :
for (CPT=="ifrs_gp:AvailableForSaleFinancialAssetsAccumulatedImpairmentLosses")
group [DIMPROPS], CPT
{VAL>=0;}
Everything is possible!
Rules are very intuitive!
Reporter-dependent!
for all
group [DIMPROPS]
{if (((VAL(CPT=="be_ifrs_fi:SpecificAllowancesForIndividuallyAssessedFinancialAssets") +
VAL(CPT=="be_ifrs_fi:SpecificAllowancesForCollectivelyAssessedFinancialAssets")) !=0)
then (VAL(CPT=="be_ifrs_fi:CarryingAmountOfTheImpairedAsset") ==0));}
for CPT == "p_cm_ca:MarketRiskCapitalRequirements" and MR=="d_mr:MRiskSACOMTotal"
group [DIMPROPS]- ["COM"],CPT
{VAL(COM==null) ~== sum(VAL(exist(COM)));}

XBRL and the CSSR, very well integrated
and a strong combination!

XBRL is highly flexible. CSSR allows to take full advantage of
this flexibility by working at concept level.
 XBRL calculations are too limited. Until formula linkbase is
available, all possible business rules can be programmed and
validated by CSSR. Afterwards, CSSR can be used to add
additional features (exceptions, tolerances,...).
 Manual entry form is available in CSSR and is based on taxo.
 In the medium term, everything can be put in the taxonomy
(instructions, business rules,...). Simply load the taxonomy in
the CSSR and make it available to the reporting agents!
 Transparancy, maintenance, new reporting projects,...
 Validation before submission: "zero error" reports should be submitted
"Management by Exception"

CSSR : Conclusions
 single software
 multi-reporting agents & multi-users
 multi-domains, multi-surveys, multi-forms
 multilevel functionalities (small or big companies)
 multilevel security
 multilingual
 multi-authorities (National Bank, Supervisor, National Accounts)
 only used by Belgian authorities
 ==> Why not widen the use of CSSR to other authorities in charge
of statistical & prudential data collection?

procedure
CSSR development conforms to the state of the art in IT business
Costs saving - greatest part of the investments already made
Costs sharing of the IT platform between the countries using CSSR
depending on the volume needed by each country
Possibility to add new domains of data collection when needed =>
good learning curve & very low costs to start the project
