+**eProsima Micro XRCE-DDS** is an open-source wire protocol that implements the OMG DDS for e**X**tremely **R**esource **C**onstrained **E**nvironment standard ([DDS-XRCE](https://www.omg.org/spec/DDS-XRCE/)).
 The aim of the DDS-XRCE protocol is to provide access to the DDS Global-Data-Space from resource-constrained devices.
 This is achieved thanks to a **client-server** architecture, where low resource devices, called *XRCE Clients*, are connected to a server, called *XRCE Agent*, which acts on behalf of its clients in the DDS Global-Data-Space.
