Overview

The Envelope Builder provides data cleaning, standardisation and encoding of data for use within LinXmart. Envelope Builder converts data from diverse sources into consistent formats for both clear text and privacy-preserving record linkages.

There are two forms to the Envelope Builder:

  • Microsoft Windows App: For manual data conversion.
  • .NET Libraries: For integration with your own systems.

Envelope Builder App​

The Envelope Builder App is a portable, standalone application for Microsoft Windows. It offers a simple interface for loading and transforming datasets for linkage. This is sometimes called the Simple Envelope Builder.

Data custodians can use the app to encode and prepare data files, making it easier to standardise and encrypt data at the source before securely releasing it for linkage.

Envelope Builder

This application is designed to take a definition file (created in LinXmart) and a source data file, and produce a Envelope, ready to be loaded into the system.

Fields defined in the project definition file can be mapped to columns in the source data file. Additional transformations (for cleaning and standardisation) can be applied at this time as well. When this mapping has been completed, an Envelope can be built.

Currently, only Linkage Requests and Probability Estimations can be created with the Simple Envelope Builder. Extracting data can be triggered through the web UI, but Batch Quality Review Envelopes must be constructed manually.

Envelope Builder Libraries​

Envelope Builder libraries are available as .NET NuGet packages from our private feed. Access to this feed can be given under a covering LinXmart Software License Agreement. Integrate these libraries into your applications to automate the separation and ETL of source data into a consistent format for linkage.
