[tdwg-tag] Lobbing grenades: a challenge

[Donald.Hobern at csiro.au]

"Grumpy old arse" or not, this is an important question.  However, I'd also like to suggest that the move to RDF has likely benefits which are not related to our ability to use semantic technologies over the data.

Given our current stage of standardisation of biodiversity data, RDF has always seemed to me primarily to be the most convenient technology to treat disparate data records as bags of properties that are asserted about a real-world object or concept.  In other words, I want to use RDF primarily as a data-transfer technology, without the closed-model or versioning issues that can arise with XML Schema, and with greater clarity and flexibility for complex data than is possible with CSV.  RDF makes it much easier for any project to reuse a set of core properties and supplement them with others specific to their interests.  This is the first and primary driver for moving to RDF.  Standardising vocabularies and semantics and moving toward the possibility of semantic exploration seems to me to be a bigger, more long-term goal.
