  Abstract Syntax Notation.One (ASN.1)
With abstract syntax the concern is solely with the information conveyed between the application program running in the computer at the weather station and the application program running in the computer at the monitoring centre.
This is because an abstract syntax itself is a type, as are its components, and their components, and so on.
The value notation is almost always an integer or object identifier value which is the delivered value, and which constitutes the "run-time" identification of the instance.

Abstract Abstract Syntax Notation One (ASN.1) defines a general framework for annotating types in an ASN.1 specification with encoding instructions that alter how values of those types are encoded according to ASN.1 encoding rules.
Introduction Abstract Syntax Notation One (ASN.1) [X.680] defines a general framework for annotating types in an ASN.1 specification with encoding instructions [X.680-1] that alter how values of those types are encoded according to ASN.1 encoding rules.
Notation for GSER Encoding Instructions The grammar of ASN.1 permits the application of encoding instructions [X.680-1], through type prefixes and encoding control sections, that modify how abstract values are encoded by nominated encoding rules.

 Abstract syntax - Wikipedia, the free encyclopedia
Abstract syntax is a representation of data (typically either a message passing over a communications link or a computer program being compiled) which is independent of machine-oriented structures and encodings and also of the physical representation of the data (called "concrete syntax" in the case of compilation or "transfer syntax" in communications).
A compiler's internal representation of a program will typically be specified by an abstract syntax in terms of categories such as "statement", "expression" and "identifier".
A parse tree is similar to an abstract syntax tree but it will typically also contain features such as parentheses which are syntactically significant but which are implicit in the structure of the abstract syntax tree.

OSI's method of specifying abstract objects is called ASN.1 (Abstract Syntax Notation One, defined in X.208), and one set of rules for representing such objects as strings of ones and zeros is called the BER (Basic Encoding Rules, defined in X.209).
ASN.1 is a flexible notation that allows one to define a variety data types, from simple types such as integers and bit strings to structured types such as sets and sequences, as well as complex types defined in terms of others.

General syntax The general syntax for content exchanged between entities according to this document associates a content type with content.
Furthermore, assuming that the content type uniquely determines the identifier octets, the identifier octets are protected implicitly in one of two ways: either by the inclusion of the content type in the authenticated attributes, or by the use of the PEM-compatible alternative in Section 9.4 which implies that the content type is data.

 ASN.1 Site - Introduction
ASN.1 is a formal notation used for describing data transmitted by telecommunications protocols, regardless of language implementation and physical representation of these data, whatever the application, whether complex or very simple.
ASN.1 definition can be contrasted to the concept in ABNF of "valid syntax", or in XSD of a "valid document", where the focus is entirely on what are valid encodings of data, without concern with any meaning that might be attached to such encodings.
But for a few addenda within the notation, the modifications were mainly editorial and consist in integrating amendments and technical corrigenda issued between 1994 and 1997.

 Using ASN.1 (Abstract Syntax Notation 1): A Data Description Language
Bethesda, MD Abstract Syntax Notation 1 (ASN.1) is used to describe the structure of data to be transferred between the Application Layer and the Presentation Layer of the Open Systems Interconnection (OSI) (next generation networking protocol).
This was done on purpose to allow various encoding rules for the same abstract syntax.
Since the value notation and binary encoded forms of data are completely and reliably interconvertible using AsnTool, there is no problem doing this.

 ASN.1: Abstract Syntax Notation One
ASN.1: Abstract Syntax Notation OneAbstract Syntax Notation one (ASN.1), an ISO/ITU-T standard, describes data structures for representing, encoding, transmitting, and decoding data.
ASN.1's encodings are more streamlined than many competing notations, enabling rapid and reliable transmission of extensible messages - an advantage for wireless broadband.
An ASN.1 definition can be readily mapped into a C or C++ or Java data-structure that can be used by application code, and supported by run-time libraries providing encoding and decoding of representations in either an XML or a TLV format, or a very compact packed encoding format.

 OSS Nokalva - ASN.1 Overview
Abstract Syntax Notation One (ASN.1) is a formal language for abstractly describing messages to be exchanged between distributed computer systems.
The protocol defines the rules of communication which include the sequencing of messages across the network, the format (or encoding) of the messages, and the interaction of the MMS layer with the other layers of the communications network.
The security label definition is expressed both as an abstract label syntax specification for the OSI Application Layer and an encoding optimized for use at the OSI Network Layer.

 OSI Protocols - Presentation Layer - Martin Baker
Although it might seem obvious that different syntaxes were needed, depending on the form of data being transferred (files, jobs, terminal streams, etc.), this was not the case and ISO worked on the development of a common protocol which can cope with any transfer syntax (analogous to the concept of a metalanguage in compiler construction).
One particular function of the presentation later is the ability to change the transfer syntax during a transfer, using the P-context-define and P-context-select primitives.
It was decided to define a rather more flexible metalanguage and this has become known as ASN.1 ("abstract syntax notation one").

In the case of the Megaco protocol, consensus between the two points of view was not reached and so two encodings, one based on ASN.1 and one on ABNF, were defined.
One may use an ASN compiler which takes as input an ASN.1 specification and generates computer code (for example in the C programming language) for an equivalent representation of the data structures.

 Definition: ASN.1 (Abstract Syntax Notation One) [Web and XML Glossary]
ASN.1 is part of the OSI model of protocol layers, it is located within the "presentation layer" (layer 6).
The approach of ASN.1 is to define an abstract syntax for the specification of structured data, and encoding rules for transforming structured data into a binary representation (which can then be exchanged).
BER is the oldest encoding for ASN.1, and a subset of it (known as DER) is used for X.509 Certificates.
