Benedikt;

(I added David Frankel to this list, you will see why in a moment as you
read. David, you will likewise understand, please read this thread.)

Your RDF Data Cube Vocabulary is right on target in my view.  There is a
group within the XBRL community which is modeling something similar for
XBRL. David Frankel is leading that effort. David can explain this better,
but in short as I understand it; XBRL is trying to leverage the work of the
on CWM, Common Warehouse Metamodel: http://www.omg.org/spec/CWM/ 

What I believe would be a good thing is if your data cube, XBRL's data cube,
and the CWM data cube were 100% semantically interoperable.

The second thing is that XBRL has a business rules language (XBRL Formula)
and business rules engines (part of an XBRL processor which implements XBRL
Formula).  Business rules provides important functionality to the sorts of
things XBRL does with financial reporting (making sure the information is
correct) and I believe that this same functionality is necessary for quality
business reporting of any kind; financial, nonfinancial, government,
industry, anything.

The question is how to put all these things together?  We have the
Government Linked Data Working Group, Data Transparency Coalition
(http://datacoalition.org/) pushing on the DATA Act
(http://keepthewebopen.com/data).  We have the ADMS folks in Europe pushing
more on semantics (https://joinup.ec.europa.eu/asset/adms/home) and I am
sure I left a few out.

How do we make all these things "play well" together and serve government
and business well, globally?

So basically, that is my view.  XBRL and your RDF Data Cube Vocabulary
should be interoperable.

I am sure you and David will have a lot to talk about!

Cheers,

Charlie

Dear Charles Hoffman,

Thanks for your recommendation to look more closely into XBRL, for instance,
w.r.t. the application of business rules on Linked Data. 

What may be of interest in this regard:

1) In GLD, we are considering to add XBRL use cases to the development of
the "RDF Data Cube Vocabulary" (QB) for publishing statistics (such as
financial disclosures). See [1] for the current vocabulary QB. Examples of
possible use cases:

1.1)  Colleagues and I have used QB at [2] (an XBRL challenge submission) to
publish XBRL filings from SEC as Linked Data and to consume those filings
using Online Analytical Processing. 

1.2) At [3] of our current QB use case document (not official, reviewed or
published), a possible use case (UC 10) is described that transforms
financial statistics as Linked Data reusing QB into XBRL.

2) There will be a paper on using rules on financial Linked Data (XBRL as
Linked Data) in the FEOSW workshop at ESWC 2012 [4]  

I would be happy to hear your opinion about using XBRL in use cases of the
RDF Data Cube Vocabulary.

Best,

Benedikt

Title: Using SPIN to Formalise Accounting Regulations on the Semantic Web

Authors: Dennis Spohr, Philipp Cimiano, John McCrae and Seán O'Riain

Abstract:
The eXtensible Business Reporting Language (XBRL) has standardised financial
reporting and provide a machine-interpretable format that makes financial
and business reports easier to access and consume.
Leveraging XBRL with Open Linked Data for purposes such as multi-dimensional
regulatory querying and investigation requires XBRL formulisation as RDF.
This paper investigates the use of of-the-shelf Semantic Web technologies to
formulise accounting regulations specified in XBRL jurisdictional
taxonomies. Specifically the use of the SPARQL Inferencing Notation (SPIN)
with RDF to represent these accounting regulations as rule constraints, not
cater for in the RDF abstract model is investigated. We move beyond previous
RDF to XBRL transformations and investigate how SPIN enhanced formalisation
enables inferencing of financial statement facts associated with financial
reporting concepts and sophisticated consistency checks, which evaluate the
correctness of reported financial data with respect to the calculation
requirements imposed by accounting regulation. The approach illustrated
through two use cases demonstrates the use of SPIN to meet central
requirements for financial data and regulatory modelling.
