Ada语义接口规范（ASIS）是Ada环境（由ISO/IEC 8652:1995定义）和任何需要来自该环境的信息的工具之间的接口。Ada环境包含有价值的语义和句法信息。ASIS是一个开放和发布的可调用接口，它使CASE工具和应用程序开发人员能够访问这些信息。ASIS被设计成独立于底层Ada环境实现，从而支持软件工程工具的可移植性，同时使工具开发人员无需理解Ada环境专有内部表示的复杂性。 受益于ASIS接口的工具的示例包括:自动代码监视器、浏览器、调用树工具、代码重整器、编码标准遵从性工具、正确性验证器、调试器、依赖树分析工具、设计工具、文档生成器、度量工具、质量评估工具、逆向工程到ols、再造工具、安全和安保工具、风格检查器、测试工具、时间估计器和翻译器。 该国际标准规定了Ada编译环境的ASIS接口的形式和含义。 该国际标准适用于Ada编译环境中需要语法和语义信息的工具和应用程序。

The Ada Semantic Interface Specification (ASIS) is an interface between an Ada environment (as defined by ISO/IEC 8652:1995) and any tool requiring information from this environment. An Ada environment includes valuable semantic and syntactic information. ASIS is an open and published callable interface which gives CASE tool and application developers access to this information. ASIS has been designed to be independent of underlying Ada environment implementations, thus supporting portability of software engineering tools while relieving tool developers from needing to understand the complexities of an Ada environment’s proprietary internal representation. Examples of tools that benefit from the ASIS interface include: automated code monitors, browsers, call tree tools, code reformators, coding standards compliance tools, correctness verifiers, debuggers, dependency tree analysis tools, design tools, document generators, metrics tools, quality assessment tools, reverse engineering tools, re-engineering tools, safety and security tools, style checkers, test tools, timing estimators, and translators. This International Standard specifies the form and meaning of the ASIS interface to the Ada compilation environment. This International Standard is applicable to tools and applications needing syntactic and semantic information in the Ada compilation environment.
