what从句的分析与理解

Coordinate transformations are defined by, what in PROJ terminology is known as, “proj-strings".

1.what in PROJ terminology is known as, 是名词性从句？

2.proj-strings 是what....从句与Coordinate transformations are defined by 主句的公共部分吗？能具体分析一下吗？

1 what in PROJ terminology is known as 是个不完整的名词性从句，介词as缺少宾语。

2 是的，what....从句与Coordinate transformations are defined by 共用名词 proj-strings。

这个句子等于下面二个句子：

Coordinate transformations are defined by what in PROJ terminology is known as “proj-strings".

Coordinate transformations are defined by “proj-strings".

第一句介词by的宾语为what引导的名词性从句（名词性关系分句）。第二句介词by的宾语为名词“proj-strings"。作者原句中的二个逗号等于括号，表示这部分可有可无。
