What Does ETL Mean in the Context of ET: Legacy?
Updated
In the context of etlegacy.com, ETL (also written ET:L) is the short name for ET: Legacy, an open source project that builds a fully compatible client and server for the online FPS Wolfenstein: Enemy Territory 2.60b. If you arrived here looking for the data-warehouse term ETL (Extract, Transform, Load), you are in the wrong place — this ETL is a game project, not a data pipeline.
What ET: Legacy actually is
ET: Legacy describes itself as "an open source project that aims to create a fully compatible client and server for the popular online FPS game Wolfenstein: Enemy Territory." Two words in that sentence do most of the work:
- Fully compatible — the project targets the existing Enemy Territory 2.60b client and server behaviour, so it is meant to work with the game as players already know it, not replace it with a different game.
- Client and server — it covers both sides of play, not just a single-player patch or a launcher.
The project presents itself as "an international community of developers and users keeping Wolfenstein: Enemy Territory alive and up to date," with development done "in an open, transparent and friendly manner."
Why the abbreviation causes confusion
| If you meant… | What it is | Where to look |
|---|---|---|
| ETL as used on etlegacy.com | ET: Legacy, an open source Enemy Territory client/server project | etlegacy.com |
| ETL in data engineering | Extract, Transform, Load — a data integration process | Data/BI documentation |
| ET:L | The same project as ETL, just a different punctuation style | etlegacy.com |
The site's own keywords list both "ET: Legacy" and "ETL"/"ET:L", which is why the abbreviation shows up in search results alongside unrelated data-engineering content.
Who this is for
ET: Legacy is relevant if you:
- Want to keep playing Wolfenstein: Enemy Territory and are looking for a maintained client and server.
- Run a server and need a compatible server build.
- Want to contribute to an open source game project — the site states "Anyone is welcome to join our efforts!"
It is not relevant if you are searching for data integration tooling, ETL pipelines, or business intelligence software.
Where to go next
The project's own site, etlegacy.com, is the entry point. Its navigation covers:
- About ET: Legacy — what the project is and its goals.
- Community — how developers and users take part.
- ET: Legacy Test Server — a place to try the project.
- Latest activities of our main repository — ongoing development activity.
- Blog Notes — project news.
For the practical side — getting the client or server and installing it — start from the download and installation information on etlegacy.com rather than from third-party mirrors, since the project is community-maintained and the official site is where its client, server, and community information live.
