req-packager

req-packager is a middleware component of EOSC Data Commons system. It act as a bridge between frontend matchmaker and dispatcher. It consist of a set of services that collect dataset and Virtual Research Environment (VRE) or tools information and assemble them into a package payload. This payload is then send to the dispatcher which is the gateway service of data players that responsible for preparing and launching the requsted VREs and tools.

req-packager interacts with the following components:

• matchmaker, which is the frontend service that interacts with req-packager to update request status and rendering for end user.
• filemetrix, which provides detailed dataset metadata used during package construction.
• tool-registry, which supplies metadata for registred tools and VREs.
• type-registry, which offers information about supported and available file types.
• Dispatcher is the final consumer of the package payload, containing all the information required to prepare and launch environments and tools.
