SSHOC D4.14 Policy API Tool

This document sets out the rationale, design and guidelines for use of the Organization for Economic Cooperation and Development’s (OECD) Family Policy Calculator Application Programming Interface (API). The API was developed and deployed as part of Task 4.5 in the Social Science and Humanities Open Cloud. The task looks to bring existing, widely used data sources into the European Open Science Cloud, increase their interoperability and integrate them within the data processing of existing Social Science Research Infrastructures. The Organization for Economic Development and Cooperations Family Policy Calculator was converted into an API and published through Plumber (a program in R) and DigitalOcean (a cloud service). This API can be queried for family policy outcomes in 35 OECD member states and provides detailed outputs regarding individuals tax position depending on their household status, income, number of children and age of the youngest child. Some examples of applications are provided, and next steps are laid out in the final section.
