+## Taverna Project Retired
+
+> tl;dr: The Taverna code base is **no longer maintained**
+> and is provided here for archival purposes.
+
+From 2014 till 2020 this code base was maintained by the
+[Apache Incubator](https://incubator.apache.org/) project _Apache Taverna
(incubating)_
+(see [web
archive](https://web.archive.org/web/20200312133332/https://taverna.incubator.apache.org/)
+and [podling status](https://incubator.apache.org/projects/taverna.html)).
+
+In 2020 the Taverna community
+[voted](https://lists.apache.org/thread.html/r559e0dd047103414fbf48a6ce1bac2e17e67504c546300f2751c067c%40%3Cdev.taverna.apache.org%3E)
+to **retire** Taverna as a project and withdraw the code base from the Apache
Software Foundation.
+
+This code base remains available under the Apache License 2.0
+(see _License_ below), but is now simply called
+_Taverna_ rather than ~~Apache Taverna (incubating)~~.

+Pull Requests are welcome to the

There are two layers of Taverna Engine:

workflow runs, potentially remotely.

orchestrating part of the Taverna Engine. Its
[Activity](https://taverna.incubator.apache.org/javadoc/taverna-engine/org/apache/taverna/workflowmodel/processor/activity/Activity.html)
