+
+   WebMon
+      Monitor for instrument status and autoreduction status at SNS and HFIR. WebMon can refer to
+      either the whole system or the landing page at https://monitor.sns.gov.
+
+   DASMON
+      Data Acquisition System Monitor (DASMON) is a per-beamline service that reports PV values and
+      experiment/run meta-data to WebMon. Due to the high volume of PV updates, DASMON writes PV
+      updates straight to the database. DASMON reports its status to WebMon for system diagnostics.
+
+   DAS
+      Data Acquisition System.
+
+   SMS
+   Stream Management Service
+      Service that aggregates data from fast neutron event data and slow PVs into a data stream
+      available for both live monitoring and file archiving. SMS reports its status to WebMon for
+      system diagnostics.
+
+   STC
+   Streaming Translation Client
+      Service that translates the experiment data stream from SMS to NeXus data file. Triggers the
+      post-processing workflow after the NeXus file has been created.
+
+   PVSD
+   Process Variable Streaming Daemon
+      Per-beamline service that subscribes to EPICS Control System PV:s and forwards PV value
+      changes to the SMS. PVSD reports its status to WebMon for system diagnostics.
+
+   PV
+      Process Variable, for example sample environment variables.
+
+   ONCat
+      Catalog for neutron experiment data at SNS and HFIR: https://oncat.ornl.gov.
+
+   SNS
+      The Spallation Neutron Source at Oak Ridge National Laboratory.
+
+   HFIR
+      The High-Flux Isotope Reactor at Oak Ridge National Laboratory.
+
+   NeXuS
+      Data format for neutron, x-ray, and muon science.
+
+   Workflow Manager
+      Service that orchestrates the autoreduction/post-processing workflow.
+
+   Dasmon listener
+      Service that subscribes to messages from :term:`DASMON` and writes to the database.
+
+   Autoreduction
+      Automated data reduction that can be triggered when the run NeXuS data file is available. The
+      instrument-specific autoreduction process is configured by the instrument scientist.
+      Autoreduction is a step in the post-processing workflow.
+
+   Cataloging
+      Cataloging of experiment data in ONCat. Cataloging is a step in the post-processing workflow.
+
+   Live Data Server
+      Service that serves plots to the WebMon front-end. :term:`Livereduce` and
+      :term:`autoreduction<Autoreduction>` can publish plots for a run to Live Data Server.
+
+   Livereduce
+      Service for live data monitoring of the data stream. Publishes plots to
+      :term:`Live Data Server`.
+
+   IPTS
+      Experiments/runs are grouped by their Integrated Proposal Tracking System (IPTS) number.
+
+   Workflow
+      Experiment data post-processing workflow. The available tasks are cataloging, autoreduction
+      and reduced data cataloging.
