R-T Configuration (v2.x and up)

Overview

This document describes the OpenCDS Configuration for version 2.x and above.

What's new?

    • Dedicated schemas for describing configuration metadata.
      • Migration tool to migrate configuration schema from the previous version (1.2.x, 1.1.x, etc.) to the new version.
    • REST interface for adding/updating and retrieving the configuration metadata
      • including reloadability of File-based configuration.
    • Backwards compatibility with ClassPath- and File-based configuration.
      • NOT compatible with previous schemas; migration is required.
    • New backend configuration scheme using BerkeleyDB (BDB-JE).
      • This is the only method that is supported via REST.

Front-end Tooling to Re-configure OpenCDS Server

Use of OpenCDS will normally require posting updates to:

  • install new or updated Knowledge Modules (KMs), and the configuration for the KMs, including any
    • Concept Determination Methods (CDMs),
    • Supporting Data, or
    • Plugins required by the new or updated Knowledge Modules.

These configuration changes can be posted to one or more OpenCDS Servers using the Front-end Tooling, which is currently implemented by a REST client.
