Tulip mania, wikipedia article
"Growers named their new varieties with exalted titles. Many early forms were prefixed Admirael ("admiral"), often combined with the growers' names—Admirael van der Eijck was perhaps the most highly regarded of about fifty so named. Generael ("general") was another prefix that found its way into the names of around thirty varieties. Later came varieties with even more superb names, derived from Alexander the Great or Scipio, or even "Admiral of Admirals" and "General of Generals". However, naming could be haphazard and varieties highly variable in quality. Most of these varieties have now died out, though similar "broken" tulips continue in the trade."

The pitfalls of using structured data
Structured data:
Problems:
Based on: [1]
- Ontologies
- Textual structures
Problems:
- Domain and purpose dependence
- Abundance of standardised formats
- Lack of standardised formats
- Poor support
- Lack of quality measures for ontologies (could be addressed by provenance tracking)
- Lack of appropriateness measures for ontologies
Based on: [1]
