1. The first is a recorded audio-only presentation to the Accounting Blockchain Coalition (ABC) on the 10th of November 2017:
This presentation is aimed at knowledgeable blockchain practitioners in the ISO, UN-CEFACT, and ABC communities, but it can be understood well because of its pictorial form. It is a little long at 55 minutes, but it can be advanced.
2. The second is a talk given to the American Accounting Association in September of 2016. This is a 30-minute video-recorded overview, based on the TED-talk format: http://aaahq.org/Meetings/2016/Accounting-Is-Big-Data-Conference/Video-Gallery/AIBD-Video-10-Public
Graham Gal, Guido Geerts, and I are done with the draft of the REA monograph, and it has been submitted to the American Accounting Association for peer review. We have actually been working on this for quite some time, and it is an excellent summary of everything we now have configured in the REA ontology. Much of this work has been reviewed at the VMBO workshops of the last 5-7 years. We hope that this will become the starting source for REA design work.
Bob Haugen’s and Lynn Foster have a wonderful website where they have adapted the REA ontology for use in Open Value Networks (like SENSORICA). Their ValueFlows is “a set of common vocabularies to describe flows of economic resources of all kinds within distributed economic ecosystems. Its purpose is to enable internetworking among many different software projects for resource planning and accounting within fractal networks of people and groups. The vocabulary will work for any kind of economic activity, but the focus is to facilitate groups experimenting with solidarity / cooperative / collaborative / small business ecosystem / commons based peer production / any transitional economies, based on REA.” https://valueflo.ws/ .
An outstanding review of REA research was recently published in May 2016:
Dunn, Cheryl; Gerard, Gregory J.; and Grabski, Severin V. (2016) "Resources-Events-Agents Design Theory: A Revolutionary Approach to Enterprise System Design," Communications of the Association for Information Systems: Vol. 38, Article 29.
There is a 2013 Ontolog Standards Conference Call on REA where my presentation went from minute 16:00 to minute 47:00. Some practitioners have found this recording useful because it gives lots of explanations for the ontological categories. I would suggest downloading my slides first to be advanced locally while listening to the recording. http://ontolog.cim3.net/wiki/ConferenceCall_2013_11_07.html
The categories used in this ONTOLOG talk have been updated slightly in the new monograph to be published by the American Accounting Association.
Some of the fundamental REA papers are available below. Some of the papers have been scanned in from the original sources, so they are large Acrobat pdf files. Others are in HTML or MS-WORD format. This list is volatile, and for those papers that have only an abstract, a full electronic or paper version can be obtained by email request from Bill McCarthy at firstname.lastname@example.org. I realize that this list of papers is far from complete, and I am trying to make access to all of the REA work easier. The available papers below constitute a very good representative set; readers who would like a more organized (but old) comprehensive overview may consult my UTS seminar schedule through which many papers are linked. Of course, that seminar was some time ago, and much has happened since. A better overview is the May 2016 paper by Dunn, Gerard, and Grabski mentioned above, and (even better) our six monograph chapters that are coming soon. Hopefully, this AAA monograph project will make the current state of affairs even clearer. On my “to do” list is an audio voice-over of a SUFE seminar in Shanghai in July 2017.
For those of you who work through these available papers and still have questions, please feel free to contact me via email or telephone.

More papers to be linked in late 2018 (sorry for delay)
Here are some other REA links:
· The Value Management and Business Ontologies Workshops in Stockholm (2009), continuing through Trento (2016) and Luxembourg (2017). These sites have additional linkages to intervening workshops. These workshops have been one of the main forums for discussion of REA ideas. The 2016 workshop in Trento (run by Nicola Guarino) was coupled with a new workshop on Value Management in Services last year. VMBO-2018 will be held in Amsterdam on 26-27 February 2018.
· Pavel Hruby's REA site:
· Kip Twitchell -- who along with Rick Roth pioneered some events-based REA principles within the IBM SAFR (Scalable Architecture for Financial Reporting) system and the earlier GENEVA system of PwC – has started a series of web videos on business events ideas. The overview segment is here, but other simple explanation segments are being added.
· There is a possibility that we may have some on-line REA presentations during 2018, coordinated by Wim Laurier. Let me know if you are interested in participating.
The second version (2015) of the open-edi accounting and economic ontology (ISO/IEC 15944-4) is now available from ISO. You may download a copy free at this website:
2007 version: http://jtc1sc32.org/free_standards.html
2017 version: http://standards.iso.org/ittf/PubliclyAvailableStandards/ .
REA work within the United Nations Trade Facilitation Group (UN/CEFACT) is due to resume in January. There is also ongoing work in OMG that I hope to pinpoint and update on a continuing basis when I move further along on the website update project. At present within ISO, we are also working on a new blockchain and open value network standard (15944-15) for open-edi that will build on REA and 15944-4. That group is meeting in Toronto in May 2018.
In my teaching at MSU, I use a lot of the REA research work, especially in ACC-821. For my prospective students, here are my teaching ratings for the years since 2011 when we switched rating scales to a 1-5 scale where scores closest to 5.00 are the best. The ratings for ACC-825 before 2017 actually combine both sections, because the MSU system lists them as one.
For 2018-2019, this is my schedule (unfortunately overbooked at present):
For those undergraduates aspiring to take our accounting MS degree systems track, my advice is to apply early as our slots fill quickly. Also, I am requiring ACC-823 be a prerequisite for ACC-825, starting in 2018, so I can combine navigational programming (JAVA) with specificational procedures for persistence (SQL). Please note that this prerequisite will be enforced without exception for the 2018-2019 academic year.
