posix - IEEE Std 1003.1, 2004 Edition : POSIX. 1-2001 或 POSIX.1-2004 的正确名称是什么？

Question

我在网上遇到了两个 POSIX 文档。

http://pubs.opengroup.org/onlinepubs/009695399/ (IEEE 标准 1003.1，2004 年版)

Abstract: The 2004 edition incorporates Technical Corrigendum Number 1 and Technical Corrigendum 2 addressing problems discovered since the approval of the 2001 edition. These are mainly due to resolving integration issues raised by the merger of the Base documents.

http://pubs.opengroup.org/onlinepubs/9699919799/ (IEEE Std 1003.1™，2013 版)

Abstract: POSIX.1-2008 is simultaneously IEEE Std 1003.1™-2008 and The Open Group Technical Standard Base Specifications, Issue 7. This 2013 Edition includes IEEE Std 1003.1-2008/Cor 1-2013 incorporated into IEEE Std 1003.1-2008 (the base document). The 2013 edition incorporates Technical Corrigendum 1 addressing problems discovered since the approval of the 2008 edition.

我想知道第一个文件是 POSIX.1-2001 还是 POSIX.1-2004。

Wikipedia article on POSIX提到第一个是 POSIX.1-2004。但为什么？第一个的基础文档是 2001 版。那么它不应该仍然被称为 POSIX.1-2001 吗？ 2004 版仅在基础文档中添加了 TC1 和 TC2。

例如，参见第二个。虽然是 2013 版，但由于基础文档是 2008 版，所以称为 POSIX.1-2008。那为什么第一个不叫POSIX.1-2001呢？

Answer 1

来自 standards(7) :

[POSIX.1-2001] was a 2001 revision and consolidation of the POSIX.1, POSIX.2, and SUS standards into a single document, conducted under the auspices of the Austin Group. [...] Two Technical Corrigenda (minor fixes and improvements) of the original 2001 standard have occurred: TC1 in 2003 (also known as POSIX.1-2003), and TC2 in 2004 (also known as POSIX.1-2004).

也就是说，POSIX.1-2001 TC2 和 POSIX.1-2004 都是正确的名称。

将标准称为 POSIX.1-2001，而不指定 TC 级别，可能会产生误导，因为不清楚是最新版本还是原始版本。 (值得注意的是，技术勘误表是 intended for clarification of ambiguities 而不是标准的主要修订版。因此，除非上下文暗示有人指的是原始版本，否则可能指的是最新版本。)
