In this context, a Coordinated Entry System (CES) is a Dept. of Housing and Urban Development/housing specific initiative, matching people looking for housing, with available housing in their community. This project is adding an open source CES to an existing open source Homeless Management Information System, named HSLynk.

This specific Coordinated Entry System CES is implemented as three separate microservices running within the HSLynk data warehouse system.

The CES does not provide any user interface, but it provides CES data via APIs to apps which provide a user interface. Currently, the CTA HOME App is the only such app.

The three separate microservices are:

Housing Inventory Service - Stores and serves housing inventory data.

Housing Matching Service - Matches clients to housing projects using assessment scores from custom client intake surveys.

Custom Survey Service - Enables the design and storage of custom client intake surveys. This can be used to create scoreable client intake assessments.
