Agenda
3 VIII CEBS-XBRL Workshop Amsterdam, 6-7 November, 2007
A communication gap between business users, in charge of expressing reporting requirements, and technical experts, in charge of developing XBRL taxonomies, has been identified as a crucial problem on COREP and FINREP projects.
1 – Multidimensional templates: the gap
Undestanding dimensional taxonomies
4 VIII CEBS-XBRL Workshop Amsterdam, 6-7 November, 2007

1 – Multidimensional templates: the gap
8 VIII CEBS-XBRL Workshop Amsterdam, 6-7 November, 2007
The question to be answered
what business people ask for
what technical people deliver
what technical people say they’ve done
How to guarantee consistency among requirements, taxonomy and documentation ?
1 – Multidimensional templates: the gap
9 VIII CEBS-XBRL Workshop Amsterdam, 6-7 November, 2007
The Matrix schema for the CR-SA template
2 – Matrix Schema
Following Column: Dimensions used in the template
1st Column: Primary items
Each row describe the breakdown structure of a primary item
Each cell contains a code that stands for the list of members allowed for the dimension in the primary item.
A sheet for each section technical people identified on the template
10 VIII CEBS-XBRL Workshop Amsterdam, 6-7 November, 2007
The exposure type domain and its sub-domains
2 – Matrix Schema
11 VIII CEBS-XBRL Workshop Amsterdam, 6-7 November, 2007
3 – Conclusions
Conclusions
XBRL-ON expects matrix schemas would:
improve communication between business people and technical people;
reduce the taxonomy debugging burden;
facilitate the understanding of COREP/FINREP taxonomies by supervised entities.
Matrix schemas are:
automatically generated from taxonomies through a reverse engineering process;
available on the COREP/FINREP website as an additional zip file.
