Overview
The i2b2export module exports OpenMRS data, including patients, providers, concepts, concept_sources, encounters, observations, and drug orders, into an custom XML schema for import into i2b2. The XSD for resulting XML document is available here: http://o2i2b2.googlecode.com/files/o2i2b2Template.xsd. The i2b2export module is part a larger framework for loading data into i2b2. A companion program, i2b2Import, which is run as a standalone application parses the i2b2 XML and loads the data into an i2b2 instance. See the diagram below to visualize the data migration process.

i2b2 is a scalable open source data warehousing tool for medical data. i2b2 is primarily used for research and excels at rapidly identifying patient cohorts through the running of ad-hoc queries. i2b2 can be used either as a data mart (project scope), a data warehouse (enterprise scope), or between multiple instances or i2b2 using [SHRINE|https://community.i2b2.org/wiki/display/SHRINE/SHRINE+Home]. i2b2 is particularly useful in hosting data from multiple systems where querying between disparate systems is typically difficult. i2b2 is also helpful in providing researchers access to clinical data without compromising patient confidentiality. This can be accomplished by deidentifying patient deidentifying patient data before importing into i2b2.
