This phase creates an upgraded postgres database using the current VegBank data model, and deploys it on an updated operating system, and with a newly designed REST API that provides a service access layer to both download and upload all data within the system. To the extent possible, this storage service will implement an API that is compatible with the DataONE REST API, to enable VegBank to become a member of the larger DataONE federation of data repositories. At the end of Phase I, the core VegBank data store will be a standalone service that can be directly accessed by both the Phase II web application and other client tools, such as commmand line browsers such as curl and scripting languages such as R and python. This system should be smaller and more maintainable than any web application that relies on it, and will be designed for maintainability.
