The Apache C++ Standard Library project (code name stdcxx, pronounced "standard C++ library", not S-T-D-C-X-X) is a collection of algorithms, containers, iterators, and other fundamental components of every piece of software, implemented as C++ classes, templates, and functions essential for writing C++ programs.
The goal of the Apache C++ Standard Library is to provide a free implementation of the ISO/IEC 14882 international standard for C++ that enables source code portability and consistent behavior of programs across all major hardware implementations, operating systems, and compilers, open source and commercial alike. An additional goal is to achieve maximum implementation efficiency on each platform by taking advantage of platform-specific high-performance facilities and features which are often unique to the type of hardware, the operating system or the compiler.
ANSI/NISO Z39.50 (=ISO 23950: "Information Retrieval (Z39.50): Application Service Definition and Protocol Specification") specifies a client/server-based protocol for
searching and retrieving information from remote databases.
