IEEE 1849

IEEE 1849 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand IEEE 1849 rather than just read about it. In short: The IEEE STANDARD 1849-2016, IEEE Standard for eXtensible Event Stream (XES) for Achieving Interoperability in Event Logs and Event Streams, is a technical standard developed by the IEEE Standards Association. It standardizes "a language to transport, store, and exchange (possibly large volumes of) event data (e.g., for process mining)".

Key takeaways

IEEE 1849 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IEEE 1849 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IEEE 1849 from memory before moving on to harder problems.

Reference excerpt

The IEEE STANDARD 1849-2016, IEEE Standard for eXtensible Event Stream (XES) for Achieving Interoperability in Event Logs and Event Streams, is a technical standard developed by the IEEE Standards Association. It standardizes "a language to transport, store, and exchange (possibly large volumes of) event data (e.g., for process mining)". In 2023, the standard has been revised in and superseded by the IEEE Standard 1849-2023. Process mining aims to discover, monitor and improve processes by extracting knowledge from event logs representing actual process executions in a given setting. Process mining depends on the availability of accurate and unambiguous event logs, according to established standards. The purpose of this standard is to provide a generally acknowledged (W3C) XML format for the interchange of event data between information systems in many applications domains on the one hand and analysis tools for such data on the other hand. As such, this standard aims to fix the syntax and the semantics of the event data which, for example, is being transferred from the site generating this data to the site analyzing this data. As a result of this standard, if the event data is transferred using the syntax as described by this standard, its semantics will be well understood and clear at both sites. IEEE 1849 was the second IEEE Standard Sponsored by the IEEE Computational Intelligence Society. The first was IEEE 1855.

IEEE Standard 1849-2023 The 2023 revision of the standard has been approved on the 5th of June 2023 and introduces the following changes:

new Micro, Software Event, Software Communication, Software Telemetry, and Artifact Lifecycle extensions updated lists of tools supporting the standard, event logs using the standard, and publications that mention the standard updated XES Schema definition, fixing a flaw related to the position of the log attributes updated bibliography

Worked examples

Example 1 — a first encounter with IEEE 1849

Start with the simplest possible case. Write down what IEEE 1849 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to IEEE 1849 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about IEEE 1849 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of IEEE 1849

In research: IEEE 1849 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses IEEE 1849 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: IEEE 1849 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Data management, IEEE standards, Standards and measurement stubs, so understanding it makes those chapters shorter.
In everyday life: Look for IEEE 1849 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is IEEE 1849 in simple terms?

Why does IEEE 1849 matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study IEEE 1849?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
