The code that does the conversion from csv to api is written in php, see here https://github.com/project-open-data/csv-to-api

We just host their code on our hosted server at http://ropensci.org/

Then we build the URL

• The base url http://ropensci.org/csv-to-api/index.php
• Then tack on the Dryad url http://datadryad.org/bitstream/handle/10255/dryad.34075/Evolution%2011-0308%20Pryke%20et%20al.%202011a.csv?sequence=1 (you can find this URL by right clicking on the csv file link on Dryad's site)
• Then specify the source format, which is csv source_format=csv
• Specify the output format format=json (could also be html, csv, xml)
• Then you can query on columns in the actual csv file. For example, there is a column called Clutch that has possible values Y and N Clutch=N
