ISO/IEC 23271:2003 defines the Common Language Infrastructure (CLI) in which applications written in multiple high-level languages may be executed in different system environments without the need to rewrite the applications to take into consideration the unique characteristics of those environments. ISO/IEC 23271:2003 consists of the following parts:
- Partition I: Concepts and Architecture - Describes the overall architecture of the CLI, and provides the normative description of the Common Type System (CTS), the Virtual Execution System (VES), and the Common Language Specification (CLS). It also provides a non-normative description of the metadata and a comprehensive set of abbreviations, acronyms and definitions, which are included by reference into all other Partitions.
- Partition II: Metadata Definition and Semantics - Provides the normative description of the metadata: its physical layout (as a file format), its logical contents (as a set of tables and their relationships), and its semantics (as seen from a hypothetical assembler, ILAsm).
- Partition III: CIL Instruction Set - Describes, in detail, the Common Intermediate Language (CIL) instruction set.
- Partition IV: Profiles and Libraries - Provides an overview of the CLI Libraries and a specification of their factoring into Profiles and Libraries. A companion document, considered to be part of this Partition but distributed in XML format, provides details of each class, value type, and interface in the CLI Libraries.
- Partition V: Annexes - Contains some sample programs written in CIL Assembly Language (ILAsm), information about a particular implementation of an assembler, a machine-readable description of the CIL instruction set which may be used to derive parts of the grammar used by this assembler as well as other tools that manipulate CIL, and a set of guidelines used in the design of the libraries of Partition IV.
