ROARMAP
» ROARMAP: Registry of Open
Access Repository Mandates and
Policies
» Searchable international registry
charting the growth of open access mandates adopted by universities,
research institutions and research funders
» PASTEUR4OA work involved developing a new classification scheme for
the registry
» Project has also added almost 300 new policy entries to the ROARMAP
database. On 24th August 2015 contains 725 policies.
» Interesting data, wanted to show in interesting ways!

WRITING A SPECIFICATION
Data Viz Brief
» Exploit the ROARMAP database and create visuals to be produced
for advocates to use in presentations, literature etc.
» Develop ways to show the statistics in an attractive form, e.g.:
›  Maps (Europe, the world, individual continents) showing where
policies are
›  Charts showing data such as funder type, what is mandatory, etc.
» Create interactive online visualisations using data dumps
» Use live data if possible
» For policy makers, institutions, researchers, individuals
25/08/2015 An Introduction to Data Visualisation 5
http://pasteur4oa-dataviz.okfn.org/
Spec: Things to think about
» What is the budget for the work?
» How much time and resources are available for the work?
» How will you get the data out of the system it is in? API, URL or other?
» Where will you store the visualisations?
» Where will you store the new data created? Will you release it openly?
» How often will the data be updated?
» Who can help you with your work?
» What is genuinely do-able?

MANIPULATING DATA
Useful Excel Functions
» Sum – adding up
» Count – the number of cells in a range that have numbers in them
» Vlookup - lets you search for specific information in your
spreadsheet
» Concatenate – lets you combine text from different cells into one cell
» Trim – removes extra spaces
» Substitute – like replace but more versatile
» Sheet/page layout – hide rows, filter data, lock columns etc.
25/08/2015 An Introduction to Data Visualisation 16
Data: Things to Think About
» You do need to be able to use excel…well
» Have you checked your data recently?
» Have you saved versions of your data and labelled them well?
» Are you keeping notes about what you are doing?
» Are you being consistent with your data?
» Make sure you document processes
» Countries can be tricky – make sure you are clear and
consistent
