Apache TLP+Incubator 一覧 2018年2月

最近、初耳なオープンソースなのに、何年も前からApacheで公開されてた〜！ということが頻発したので、一念発起してApache TLPとIncubatorの一覧を整備してみました。

一覧整備の中で気になったプロジェクトをまとめた、[ほとんど知られていない、IoTに役立つ10個の最新Apacheプロジェクト - 2018年2月] (https://qiita.com/toast-uz/items/4e1601bbc07d1d774418) も参照ください。

# 1. Apacheソフトウェアとは

Apacheソフトウェア財団（Apache Software Foundation）によって管理されるオープンソースを、Apacheソフトウェアと呼ぶ。そのライセンスはかなり緩い方で、派生プロダクトの商用非公開利用も一定の条件のもと可能であるため、活発にソフトウェアが追加されている。Apacheというと、1990年代ではWeb Serverの代名詞であったが、近年ではApache Hadoopをはじめとするビッグデータ関連ソフトウェアに強い。

## 1.1. Incubatorとは

Apacheソフトウェアになる応募をして一定の条件をクリアしたオープンソースは、Apacheの名称を関することが許され、実験プロジェクトの位置づけでIncubatorとして登録され、支援を受けられる。（Podlingとも呼ぶ）

Incubatorプロジェクトは一定の条件のもと、中断もしくは卒業を果たす。卒業にあたって、過去のApache TLPのサブプロジェクトになるか、新規のTLPとなる。

## 1.2. TLPとは

TLP（Top Level Project）は、専用のPMC（Project Management Committee）と呼ばれる委員会が組織され、Apacheの正式プロジェクトとして運営される。

# 2. TLP一覧

[Apache Projects](https://projects.apache.org/) によると、現在、約170のTLPが存在する。2000年代まではJAVA関連、2010年代はビッグデータ関連が主流になってきている。

Committee(TLP)配下に複数のオープンソースをホストしているものもある。また、オープンソースプロジェクトを1つもホストしていないTLPもある。なお、Categoryは各TLPの自称なので、未設定のものも多く、かならずしもレベルは合っていない。

以下にTLP昇格年代の降順で並べてみた。2014年以降のプロジェクトには、最近の旬のものが散見される。
