Transcript of XBRL Panel -- Bill McCarthy Researcher (?) Professor of Accounting at Michigan State University...
XBRL Panel -- Bill McCarthy
• Researcher (?)• Professor of Accounting at Michigan State
University– more IT than accounting– more design science than empirical
• Business Process standards worker• Topics:
– ebXML progress and fit with XBRL– Research opportunities
• Design science• Empirical science
Origins of my (biased) views
FSA & ELOISE (KEE & Lisp) knowledge
structures
semantic modeling in DB, AI, OO
AA-AI group work on EDGAR
in 86-87
Semantic nets for text
Chart of accounts
Semantic Modeling
• transactions & commitments
• reporting
• controls
XBRL
• reporting
• transactions
• controls
Comparison & connection of ebXML (UN/CEFACT) with XBRL (AICPA)
• ebXML progress – Fast start but slow progress and migration (OASIS, OAG, OMG)
• Some specs progress to ISO• BP catalog & classification repository• Business process semantics & choreography
– BP metamodel– Business entities (states) & collaboration patterns– ebXML stack– Connection with XBRL
• Bill for one year
• UN/CEFACT – not much
Research Opportunities – (DS)
• XBRL & other XML initiatives are exciting & hard topics (don’t come in with weak skills)
• Design Science = building (constructs, models, methods, instantiations) and evaluating (same) HMPR link
• DS opportunities– Building of new design artifacts for XBRL (tools,
taxonomies)– Evaluating of existing artifacts (XLink, taxonomies, best
methods & practices, instantiations)
Research Opportunities – II (empirical)• Traditional Financial reporting with new decision scenarios
for analysts & investors– Instant Compustat & other data aggregators– New tool & technology use– Other reporting issues (access accounting, interactive
data)– Opportunity not yet ripe but will be soon (AAA report)
• XBRL G/L uses– G/L to G/L– Other projected uses ?
• New use of G/L• Transaction level interoperability
• Other new XBRL use
Research Opportunities – A Final Note
• Opportunities in both design and empirical, but beware of establishment biases
• Research obligations (?)– Unbounded optimism about adoption is part of the
XML landscape, and it is fine for XBRL.org and the AICPA
– “Why so few faculty opponents ?”• Heavy learning curve• Non open development process (ODP) makes criticism hard
for researchers• Skeptics are hard to identify & quote• Nothing in XBRL needs fixing
