XBRL Ontology Project Aims
kidehen
The parallel evolution of the XBRL and the Semantic Web is one of the
more puzzling of technology misnomers. The Semantic Web expresses a
vision about a Web of Data connected by formal meaning (Context).
Congruently, XBRL espouses a vision whereby by formally defined
Financial Data is accessible via the Web (and other networks). The
Semantic Web uses Schemas and Ontologies for defining Data Domains
while XBRL uses Taxonomies that are XML Schema Based. The Semantic Web
uses XML as one of its Data Interchange formats (i.e RDF/XML) while
XBRL is based on XML at all levels (model and instance data).
It is the goal of the XBRL Ontology project that we mesh the XBRL and
Semantic Web realms by producing OWL based Ontologies for XBRL's XML
Schema based Taxonomies as this is a critical prerequisite for
generating RDF Instance Data (Triples) from XBRL Data Sources (e.g.
XBRL Documents). This effort is not intended to supercede the use of
XML Schemas in XBRL in any way. It simply provides a mechanism for
exposing XBRL based Financial Data to the Semantic Data Web.
What are the anticipated deliverables:
1. OWL Ontologies for XBRL Taxonomies such as the XBRL GL (and others)
2. Sample RDF instance data for the XBRL Ontologies
3. SPARQL (Semantic Web Query Language) based Access Points for
sample XBRL Instance Data
Benefits:
1. Transparent integration of data produced by disparate financial
systems by:
- Mapping of application data (e.g. SQL) to relevant XBRL
Ontologies which are then exposed to WAN (Web) or LAN (Intranet) via
SPARQL access points
- Production of RDF Instance data from existing XBRL documents on
the Web
2. An easy mechanism for plugging XBRL data into burgeoning Semantic
Data Web

I would like to point you to the MUSING project launched by several EU
companies and Eupropean research institutes. I have attended the
creation of several XBRL ontologies last summer. If you would like, I
can introduce you and your project to them, and we may have some
cooperation on this common interest.

Well yeah, it would be more than appreciated. Is there any references, links,
etc. to hese resources and the MUSING project?

As indicated by Fred already, we are absolutely about collaboration.
The last thing we want to do is reinvent the wheel here, so any work
in this area that as been done should be exposed via a URI :-)

Here is the web site of the MUSING project: http://www.musing.eu/. It
is a multi-million-euro project in four years. In particular, the OWL
version XBRL taxonomy conversion research is conducted by Martin Hepp,
who is affiliated in DERI Innsbruck. Last summer, I was with his team
and we together studied some fundamental research on the methods to
convert XBRL to OWL. Moreover, his team has already successfully
converted several existing XBRL standards to OWL ontologies
(especially some European taxonomies, which could be a well complement
to the US and Canada specifications).
Martin is a very brilliant and kind scientist. He would be glad to
share with you people, I believe. Moreover, personally I would like to
make some contributions to this project too. Based on my research
last summer in Innsbruck, I believe this is a very valuable project,
and I would like to continue contributing to this effort.
cheers,

Certainly. I have already replied Fred's mail about the MUSING
project. I highly value the worthiness of this effort about
converting XBRL taxonomies to OWL. Financial reports are a chunk of
very much valuable resources that could and should be prompted by the
semantic web technologies. More importantly, financial reports
usually demand rigid and even stiff rules to protect their
preciseness. This property could help us avoid many ambiguities,
which are often the most difficult issue when handling real-world
semantic web applications. I am glad to know this new launched effort
and willing to do my part of contribution to this great event. Let's
see how we can cooperate better in the future.

Yihong

Because I contacted these researchers and got only one answer about 1
month ago, and nothing since then (and I cannot see Mr. Hepp's name in
the paper).
Also, what is the purpose of this XBRL taxonomy conversion research? The
thing is that I can't find anything vis-a-vis this effort on MUSING's
website. Would be nice to get some conversations examples, etc :)

Well you are more than welcome! you expertise in the domain is more than
welcome.
The team is growing up quickly, we should start to talk about how we
plan to proceed for the first steps.

it would be very useful to deal with the possibilities of
interconnections between XBRL taxos and ontologies.I hope that the
results of the MUSING project as well as other scientifc results (as
far as I can see, at least one member of this group is invilved in
such a project) could be used here.
Perhaps I can meet some of you at the forthcoming international XBRL
meeting in June in Munich.
I did some embedding work more intuitively at the times of XBRL 2.0
(when definiton linkbases existed, I used the to define the parent-
child relation in an ontology).

The paper you mentioned is written by Thierry and one of his
colleague. They are from DFKI, which is another sub-contractor in the
MUSING project. Thought Thierry and Martin are good friends, they are
in two different institutes. Besides them, Ruben Lara and others also
published a paper on this topic, "XBRL taxonomies and OWL ontologies
for investment funds." It was on a workshop co-located with ER-2006
(Martin is the workshop organizer).
At that time, Martin and I had studied some fundamental methods on
automating ontology conversion between XBRL and OWL. Due to the short
term I stayed with DERI, we had not experimented much on our
methodologies. But I know that they had converted several XBRL
taxonomies to OWL (possibly by hand on most of them) for the MUSING
project after my leaving. There is a repository of these converted OWL-
version XBRL taxonomies. I prefer to not releasing it to the public by
me since I am not the owner. I would suggest asking for Martin to
release a public access to their work since there might be some legal
issues on using these results for the purposes other than personal
research (I am not sure though). But anyway, I can help if this is
really a general interest to this group.

Okay, as you know, I sent him an email about that, so we will see.
Hope that we start collaborating on that initiative. We will check what
we can do vis-a-vis the rights on their work, etc. Anyway, I have really
happy to have you on board to start the development of that ontology.
Take care,

projects that already working on the issue, and to get feedbacks and
opinions from the larger number of people that as an interest in the
project. Vis-a-vis the MUSING project, I contacted Mr. Hepp, so we will
see what happen with that.

exactly parallel to the interntl XBRL meeting in Munich, the ESWC
meeting takes place at DERI in Innsbruck I just learned. Martin Hepp
is one of the driving persons there.
Concerning the general aims of our group, I would firstly contribute
some of my starting points:
- to define the transformation of the XBRL taxo elements (as concepts
or classes, straightforward to my opinion)
- define or make selectable for a transformation which linkbase
defines the subclass hierarchy
- the role of the other linkbases (as relations/attributes ...) as
well as the multidimensional features of XBRL (used in the COREP/
FINREP taxos e. g.)
- to deal with the notion of "context" in the XBRL sense (not
contained in the schema files).
- other XBRL features like the rule language used in XBRL (which
should be substituted by a general web rule language to my
unfortunately privat opinion, perhaps somebody in this group can
convince the "pope of XBRL" to follow this idea...)
Other ideas will follow when some starting point is set.
But of course I hope to learn more about the transformation principles
followed by the researcher groups known till now (M. Hepp and the
Spanish group. By googling, I have the impression that on Taiwanesian
universities, researchers deal with such questions too but the
findings are denoted only in Chinese letters ...).
As I told, my work done in the past was based on XBRL 2.0 , where the
definition linkbase was used to define the subclass hierarchy, so this
is no longer usable for a general solution. I dealt only with GAAP
taxos (German, IFRS, UK, older US-GAAP-taxos). One problem in this
area is the "principle of modularization" of many GAAP taxos (like the
newer IFRS taxo(s), the US GAAP taxos, not the German one which is a
smooth compact taxo to my opinion).
If it makes sense, I can post some screenshots here.

This is great, would be interesting if someone could meet him to check
if it would be possible to have more information about their work.

Yeah, and how to create an ontology that has the power to describe all
these different taxonomies. I think this is the real challenge here:
describing all current taxonomies as long as all the taxonomies that
doesn't even exist yet).

Good, what I would like, if it is possible for you, is to put these
bullets on the wiki (wiki.xbrlontology.com) so that people could
extend them with their personal opinions, etc. So this could be a
starting point and a way to define the scope of this ontology.

Yeah, I hope too, and what I hope is not re-doing what other people
have already done in the past: a wheel should keep rolling, not re-
invented each time :)

Yeah sure, go ahead. Here and/or on the wiki so that we can keep a
track of these screenshots.

Well, an ontology that describes the metamodel of XBRL with rules of
creation could be the point. This is a nice scientific task I think,
perhaps a bachelor thesis we could propose to the academic scientists
here or outside this group. I could play the role of a practical
advisor ...

Yeah it is sure that it could be a great way to get the first step done
for the elaboration of this ontology. In fact, the first goal was to
create this community to do exactly that. However, if you know anyone
interested in that, then we could proceed that way and help him to do
that work.
So, go ahead with that idea and check if someone could be interested and
keep me updated :)
Take care
