Apache Etch (in the Attic) (a project managed by the Apache Attic Committee)

Etch is a cross-platform, language- and transport-independent framework for building and consuming network services. The Etch toolset includes a network service description language, a compiler, and binding libraries for a variety of programming languages. Etch is also transport-independent, allowing for a variety of different transports to be used based on need and circumstance. The goal of Etch is to make it simple to define small, focused services that can be easily accessed, combined, and deployed in a similar manner. With Etch, service development and consumption becomes no more difficult than library development and consumption.

Etch是一个跨平台、独立于语言和传输的框架，用于构建和使用网络服务。蚀刻工具集包括网络服务描述语言、编译器和各种编程语言的绑定库。蚀刻也是传输独立的，允许根据需要和环境使用各种不同的传输。Etch的目标是简化定义小型的、集中的服务，这些服务可以以类似的方式轻松地访问、组合和部署。随着刻蚀技术的发展，服务开发和消费不再像图书馆开发和消费那样困难。
