Highlight of Features
Top New Features
| Description | ||
|---|---|---|
New Web client User Interface |
| The completely rewritten web client represents a major step forward for i2b2 that features an improved layout, greater visual customization, and a new plugin architecture. The new web client version eliminates usage of YUI and uses the latest versions of jQuery, Bootstrap 5 and Golden-Layout libraries, which will ensure maintainability far into the future. |
ACT i2b2 on OMOP for MSSQL and Oracle databases | The core i2b2 platform now supports the OMOP data model, which is queryable through the comprehensive ENACT Ontology. (MSSQL and Oracle are supported. Postgres support will be added in 1.8.1.) | |

ACT i2b2 on OMOP for MSSQL and Oracle databases
ACT i2b2 on OMOP functionality uses ACT Ontology in the front-end and enables the i2b2 Software to run against a database that uses the OMOP CDM architecture. For historical reference on old 2018 OMOP installation , refer to OMOP Home - OMOP - i2b2 Community Wiki
The following steps will load the OMOP metadata and CRC tables and the OMOP Views required to query the OMOP tables: i2b2-on-OMOP With ENACT-OMOP Ontology v4.1
ACT OMOP Totalnum Scripts
Totalnum Scripts (patient counting scripts) have been updated to improve the counter's performance on both multiple ontology tables and very large(>1.5 million) ontologies such as ACT medications. Debug messages have also been added for troubleshooting and profiling purposes. Support for multiple fact tables has been added and bugfixes have been made.
Patient Counting Scripts ("totalnum")
Improved CRC scripts execution Process
Prior to 1.8 release, CRC scripts via ANT execution command supported single CRC zip folder structure. 1.8 release will support multiple CRV zip folder execution. The databuild.xml has been modified for this process.

Notes for Developers
For Java 11 install, if you change the xsd (REST API message definitions), then you will need to regenerate gensrc via JAXB in Java 8. In the i2b2-core cell directory for which you're regenerating the XSD-Java, run the ant target "jaxb_gen" on Java 8 and then build as usual using Java 11.
