Harvest SRU API results as JSON

You can query the People & Organisations data using the SRU (Search/Retrieve via URL) API, and retrieve data in a number of XML formats, the richest and most complex of which is EAC-CPF. However, the XML records are not easy to work with, so to simplify further processing, this notebook queries the SRU interface and then converts the EAC-CPF XML results into JSON.
