# 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.
