VODAN-in-a-Box consists of two significant services:
Data Stewardship Wizard (DSW) adjusted to serve as Wizard for filling and maintaining electronic case report forms (eCRF),
FAIR Data Point (FDP) to maintain metadata about eCRFs created in DSW.
To support it, there are other services included:
AllegroGraph triple store for eCRF data and queries,
BlazeGraph triple store for FDP,
MongoDB used by both DSW and FDP,
JSON server providing controlled vocabulary for filling answers,
Submission Service that handles storing eCRFs in triple store and updating metadata in FDP,
RabbitMQ for queueing generation of an eCRF to a RDF document using DSW document worker,
(optionally) Nginx proxy for Production Deployment.
