Components

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.
