Release Notes 0.23.6

Overview

The 0.23.6 release is a strongly recommended upgrade for ALL Learning Registry node deployments, as some internal changes that make distribution more compliant towards the LR Service specification cause distribute functionality to fail when interacting with nodes running versions prior to 0.23.6.

Below find the key features addressed in this release.

To upgrade an existing installation, please review the Upgrade Guide for 0.23.6.

Key Features

  • Data Services NEW
    • The extract API is included and enabled in this distribution. The Extract API brings a "batteries included" interface for tailoring data extraction and query to suit more narrow and varied use case needs without high resource requirements.
    • Data Service views are NOT installed by default. Node administrators can install any or all of the 3 standards alignment focused data services using python CouchApp. This is done to prevent unneeded consumption of disk space for data services not utilized.
    • Interactive documentation explaining Data Services and how to roll your own for your use case.
  • Resource Data Distribution refactoring CHANGED
    • Distribute has been significantly refactored to reduce the need for 2x storage for documents. New distribute uses 2 DB's, incoming and resource_data. New tainted documents can be distributed to incoming, and node may impose an internal policy for untainting documents before moving into resource_data. All harvest services still operate against resource_data.
    • More compatible with Learning Registry 0.23 specification. Document Types of resource_data are distributed, not resource_data_distributable.
    • Upgrade will require some minor configuration changes to NGINX to change or expose incoming endpoint.
    • IMPORTANT Legacy nodes can distribute to a 0.23.6 by adjusting service documents to use the incoming endpoint. Legacy cannot be the destination for a 0.23.6 server.
  • Subscription for Distribute NEW
    • You may now visit http://[node address]/register, enter the URL of your node (use https if SSL required to access).
  • Support for CouchDB 1.2.0 NEW
    • This is a highly recommended upgrade. Significantly improves the storage and resource utilization, as well paves path for features planned for future releases.
  • Many Bug fixes

Minimum Requirements

  • Linux/Windows OS
  • NGINX w/ uwsgi support
  • Python 2.7.3 (+setuptools; +virtualenv)
  • CouchDB 1.1.1 (1.2.0 Recommended)
