What? What?
Explore data portal/catalogs
Chunk up data and reassemble
into a meaningful argument
Share that argument
Have others derive work from
your findings
IntroIntro

4. Ultimately...Ultimately...
goal is to model and share a thought process based on open
data
IntroIntro
has to be
shareable -> open data
verifiable -> assessment of authenticity of sources
reproducible -> standards-based, open description of process

5. Preamble : Data standardsPreamble : Data standardsTechTech
as the 3rd star of open data,
it should be obvious by now... but considering the current state
of open data, it's better to rub it in
XLS sheets
ZIP files
a link to a webpage that gathers some
data
....
are not open data standards!

17. Grounding DataGrounding Data
annotations model is RDF-based and queriable in SPARQL
--> graph of all annotations constitutes grounding material for
data itself, and gives context and semantics to data
