You need to install the RISE Ipython Library from Damián Avila for dynamic presentations
To convert and run this as a static presentation run the following command:
In [ ]:
!ipython nbconvert 20151008_OpenGeo_Reuse_under_licence.ipynb --to slides --post serve
To close this instances press control 'c' in the ipython notebook terminal console
Static presentations allow the presenter to see speakers notes (use the 's' key)
If running dynamically run the scripts below

Cartography was king. Static representations of spatial knowledge with the cartographer deciding what to represent.

From Map to Model The changing paradigm of map creation from cartography to data driven visualization

Issues surrounding non-technical interoperability include:
We will focus on licence interoperability
\newpage
There is a multitude of formal and informal data.
\newpage
Each of these data objects can be licenced in a different way. This shows some of the licences described by the RDFLicence ontology
\newpage
Concepts (derived from Formal Concept Analysis) surrounding licences
\newpage
Two lead organisations have developed legal frameworks for content licensing:
Until the release of CC version 4, published in November 2013, the CC licence did not cover data. Between them, CC and ODC licences can cover all forms of digital work.
I'll describe CC in more detail
\newpage
The following clauses constrain CC0:
\newpage
\newpage
Certain licences when combined:
A conceptual licence processing workflow. The licence processing service analyses the incoming licence metadata and determines if the data can be legally integrated and any resulting licence implications for the derived product.
