**# ETSI ISG Context Information Management
As part of its mission, the ETSI Industry Specification Group on cross-cutting Context Information Management (ISG CIM) drives the specification of an Application Programming Interface Specification/API, named NGSI-LD, which aims to enable applications to discover, access, update and manage data and context information from many different sources making it the interface of choice for getting access to Digital Twins data and managing their capabilities.

Purpose

The goal of the liaison is to evaluate the potential of using W3C WoT Things Models for the description of NGSI-LD entity types as well as specifying how default WoT Things Descriptions can be derived from WoT Things Models using the NGSI-LD API as the form to interact with Things.
