+# Light OM2M : an efficient and oneM2M-compliant middleware for interoperable IoT applications.
+##oneM2M
+oneM2 is an IoT standard which helps build interoperable IoT solutions.  This requires that oneM2M-compatible software runs on various layers of the system. However today’s implementations are not optimized to run efficiently on resource-constrained devices, such as a low-cost gateway.
+##Light-OM2M
+Light-OM2M is an implementation which lets you benefit from oneM2M standard services on resource-constrained devices. 
+It builds upon years of experience and fedbacks acquired by the same project manager and developers team of Eclipse-OM2M, one of the oneM2M reference open-source implementation.
+Light-OM2M is supporting oneM2M services : 
+Resources: ACP(1), AE(2), CNT(3), CIN(4), CSB(5), CSR(16), SUB(24)
+Operations: CREATE, RETRIEVE, DELETE, SUBSCRIBE, DISCOVER
+Features:
+Communication protocols (HTTP & MQTT - restricted version)
+Security: access rights management - restricted version
+Subscriptions management
+Discovery (filter criteria: level, resource type, labels, limit)
+## Some characteristics
+- language: C++
+- Operating system: Arduino (ESP8266), Unix based system with docker
+- RAM footprint: around 60KB on ESP8266 and 3MB on UNIX system
+- Binaries footprint: around 500KB ROM on ESP8266 and 5MB on UNIX system
