I'm not the worlds greatest fan of applying very general, very abstract models to day-to-day problems.
That does not mean I am not a fan of that bedrock of knowledge representation : the humble triple (for example: subject,predicate,object).
I found myself wondering where on earth all the triples are out there in the real world of day-to-day IT, as opposed to the perfect but more abstract worlds of RDF/Topic Maps/HyTime etc?
Then it hit me.
Spreadsheets:-) Think about it. Row 1 cells - subject. Col 1 cells predicate. Other cells: objects...
