Feature Details - Release 1.7.11

New Feature: Role-based Ontology Protection

The top-level categories/folders in your ontology can now be optionally protected by one or more i2b2 roles (e.g. DATA_LDS, DATA_PROT, etc.) This feature allows the administrator to define one or more roles for an individual root folder in the ontology, and users without one of these roles will not be able to see the ontology item or use any of the terms in this folder.

To use this new feature and protect a root level folder, follow these steps:

1. In your TABLE_ACCESS table in your ontology database, set C_PROTECTED_ACCESS to 'Y' for the root level folder you would like to protect.
2. There is a new column in TABLE_ACCESS called C_ONTOLOGY_PROTECTION. This is where you can define one or more roles in a comma-separated list (e.g. DATA_LDS,DATA_PROT)

Example:

If you wanted to create a root level folder in your ontology called "PHI Demonstration" and only wanted users with the DATA_PROT role to be able to see it, you would make the following changes to your TABLE_ACCESS table:

New Feature: Previous Queries Upgrade in Web Client

The Previous Queries panel in the web client has been upgraded to accommodate three new options.

• Filter Previous Queries List by User - Users with the MANAGER role will now see a drop down in the Previous Queries Options menu that allows them to filter previous queries by a specific user in the i2b2 project.
• Auto Refresh Previous Queries - Users now have the ability to set an auto-refresh timer in the Previous Queries Options menu in which the Previous Queries list will auto-refresh in the specified time period (off, 10 seconds, 30 seconds, or 60 seconds).
  
• Page through Previous Queries by Date - Users can navigate Previous Queries by a particular date.
  
  

New Feature: Support for WildFly 14

The i2b2 software now officially supports WildFly 14. The primary advantages are the faster install/upgrade of i2b2 as a pre-packaged collection (WAR) and managed data source connections/pooling.

Updated: i2b2 License

The i2b2 software is now made available under the terms of the Mozilla Public License (MPL) version 2.0. i2b2 is also distributed under the terms of the Healthcare Disclaimer addendum.
