PRIMAT is an open source (ALv2) toolbox for the definition and execution of PPRL workflows. It offers several components for data owners and the central linkage unit that provide state-of-the-art PPRL methods, including Bloom-filter-based encoding and hardening techniques, LSH-based blocking, metric space filtering, post-processing and more.
PRIMAT is developed by the Database Group of the University of Leipzig, Germany.

The data owner application consists of components for pre-processing (data cleaning and stardadization) functions and Bloom-filter-based encoding of records containing person-related data.
To run the data owner application run the following command in the primat directory (where the pom is located):
mvn clean javafx:run -Dprimat.mainClass=dbs.pprl.toolbox.data_owner.gui.DataOwnerApp
The linkage unit application provides linkage functionalities, in particular blocking, similarity calculation and classification, post-processing. Furthermore, it consists of evaluation facilities to compare different PPRL workflows in terms of quality (recall, precision, f-measure) and scalability (runtime, reduction ratio).
To run the linkage unit application run the following command in the primat directory (where the .pom-file is located):
mvn clean javafx:run -Dprimat.mainClass=dbs.pprl.toolbox.lu.gui.LinkageUnitApp
