The project entered the Apache Incubator in November 2010 and graduated as an Apache top-level project on 2012-02-15. The incubation record describes the project goal as creating a mature toolkit for common NLP tasks and providing pre-built models for multiple languages. The Apache-era project continued to ship both a Java API and a common opennlp command-line entry point. ### Adoption history OpenNLP's adoption is strongest in Java and JVM text-processing pipelines where developers want a conventional library and CLI for classic NLP rather than a server or hosted model. Its old SourceForge model archive and Apache manual both show the long-running package culture around downloading binary models, running trainers, and wiring the toolkit into UIMA or custom applications. As newer deep-learning NLP stacks arrived, OpenNLP remained relevant for lightweight, inspectable, trainable components and for organizations with Java pipelines that need sentence splitting, tokenization, tagging, NER, and parser tools without adopting a Python-heavy stack. ### How it is used The Homebrew package exposes the opennlp command. Apache's manual says the binary distribution includes an opennlp script for Linux-compatible systems and opennlp.bat for Windows, with OPENNLP_HOME and PATH used to make the tools convenient. Typical CLI usage invokes a tool name plus a model, reading from stdin and writing to stdout, or runs trainer commands with model output, language, training data, encoding, and task-specific options. That makes the package friendly for shell pipelines and repeatable model-training experiments. ### Why package nerds care OpenNLP is appealing to package nerds because it is a Java NLP library with a real Unix-style CLI surface. You can install it, fetch or provide models, pipe text through tokenizers or taggers, and train task-specific models without building an application first. It also carries a visible history of pre-Apache open-source distribution: SourceForge-era releases and models, Apache incubation, Maven artifacts, and a CLI that still exposes the toolkit as a collection of small named NLP tools. ### Timeline - 2010: OpenNLP enters the Apache Incubator. - 2011: Apache OpenNLP 1.5.2-incubating is released. - 2012: OpenNLP graduates as an Apache top-level project. - 2026: Apache documentation lists current 2.x and 3.x milestone manuals and Javadocs. ### Related projects - Apache UIMA is an adjacent Java text-analysis framework with documented OpenNLP integration. - SourceForge-era OpenNLP models, Maven Central artifacts, ONNX Runtime support, and Java NLP pipelines are common adjacent pieces. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Other Package-Manager Records - Debian apt - libapache-opennlp-java - 2.5.3-1: normalized package name match | Debian stable package indexes: libapache-opennlp-java from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | machine learning based toolkit for the processing of natural language text | https://opennlp.apache.org - Debian apt - opennlp - 2.5.3-1: normalized package name match | Debian stable package indexes: opennlp from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | wrapper for Apache OpenNLP natural language text processing toolkit | https://opennlp.apache.org - Ubuntu apt - libapache-opennlp-java - 2.3.2-1: normalized package name match | Ubuntu 24.04 LTS package indexes: libapache-opennlp-java from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | machine learning based toolkit for the processing of natural language text | https://opennlp.apache.org - Ubuntu apt - opennlp - 2.3.2-1: normalized package name match | Ubuntu 24.04 LTS package indexes: opennlp from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | wrapper for Apache OpenNLP natural language text processing toolkit | https://opennlp.apache.org - zypper - opennlp - 1.9.5-2.1: installed executable or alias match | openSUSE Tumbleweed package metadata: opennlp from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | A machine learning based toolkit for the processing of natural language text | https://opennlp.apache.org/ - zypper - opennlp-morfologik-addon - 1.9.5-2.1: installed executable or alias match | openSUSE Tumbleweed package metadata: opennlp-morfologik-addon from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Apache OpenNLP Morfologik Addon | https://opennlp.apache.org/ - zypper - opennlp-tools - 1.9.5-2.1: installed executable or alias match | openSUSE Tumbleweed package metadata: opennlp-tools from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Apache OpenNLP Tools | https://opennlp.apache.org/ - zypper - opennlp-uima - 1.9.5-2.1: installed executable or alias match | openSUSE Tumbleweed package metadata: opennlp-uima from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Apache OpenNLP UIMA Annotators | https://opennlp.apache.org/ ## Combined YAML source View the package source record on GitHub.
