Back in 2005, in the strange and heady times of post-bubble dot-com development, Dan Marcus took a trip to Amazon headquarters to meet their CTO and promote a very young XNAT among up and coming "big data" research tools. He was blown away by Amazon's commitment to developing their nascent Amazon Web Services software as a services platform, powered entirely - inside and out - by a commonly accessible API. That inspired the XNAT development team to commit to making its capabilities – creating, organizing, searching and downloading data – powered by a set of RESTful services, accessible by a common API.
The API has grown and evolved considerably since its first appearance in XNAT 1.3 – to the point that our documentation is still trying to keep pace. Please pardon our dust as we continue to build out this section over the coming months.
