The Data Ecosystem Schema Mapping (DESM) tool is one of the projects that I am working on for the US Chamber of Commerce Foundation’s T3 Innovation Network.  DESM is a specialized tool for creating, editing, maintaining and viewing crosswalks between data models, these crosswalks are based on the degree of semantic alignment between terms in the different schemas. Colleagues on the project have produced two one-page fliers about DESM that have just been published: one explaining what DESM is and how it works, the other providing guidance on mapping projects that use DESM.

Watch this space for more about our use of DESM in both T3 and Credential Engine projects.
