# Glossary

Guidelines:
 - Include terms specific to the OpenBMC project, OpenBMC reference
   platforms (like OpenPower or ASpeed), BMCs, or platform management.
 - Include terms needed to disambiguate.  For example, "image" may refer to
   a visual (e.g., JPEG) image or a firmware (e.g. UBIFS) image.
 - Treat acronyms the same as terms.

BMC - Baseboard management controller.  A device designed to enable
remote out of band management access to a host, generally a computer
system.

D-Bus - Provides the primary mechanisms for inter-process
communication with an OpenBMC system.  OpenBMC D-Bus APIs are
documented in `https://github.com/openbmc/phosphor-dbus-interfaces`.
For example, see the tree under `/xyz/openbmc_project/Led`.

IPMI - Intelligent Platform Management Interface.  OpenBMC implements
a subset of the IPMI spec.

ODM - Original design manufacturer.  In OpenBMC, ODM generally refers
to the manufacturer of the host system.

OEM - Original equipment manufacturer.  In OpenBMC, OEM generally
refers to the manufacturer of the host system.

Phosphor - Informally designates OpenBMC software or APIs designed for
use across many systems, as distinct from platform or vendor-specific
elements.

Redfish - The Distributed Management Task Force (DTMF) Redfish
specification.  OpenBMC provides Redfish REST APIs for platform
management.

REST - Representational State Transfer.  OpenBMC provides REST APIs.

SDR - IPMI Sensor Data Record.

SEL - IMPI System Event Log.  The BMC stores SEL events.

Server - A computing device, generally the one served by the BMC.
