Going Horizontal – Comparing Open Data Vocabularies Across Domains, XTech 2006, May 2006, The Dutch government is actively promoting the use of digital exchanges. XML-based open standard vocabularies are rapidly appearing in Healthcare, Criminal Justice, Social Security and Financial Reporting. Currently the developments are taking place within not across those separate domains. It’s about time to compare the different approaches. What is different and what’s the same? Where is the common ground, and what can be gained by standardization? What works and what doesn’t in building vocabularies?

What is ‘is’? (English)XML 2001, Orlando, Florida on interoperability between B2B-vocabularies. The presentation starts with a philosophical introduction on reference, based on the work of Frege and Wittgenstein.
