In computing and telecommunication, a control character or non-printing character (NPC) is a code point in a character set that does not represent a written character or symbol. They are used as in-band signaling to cause effects other than the addition of a symbol to the text. All other characters are mainly graphic characters, also known as printing characters, except perhaps for "space" characters. In the ASCII standard there are 33 control characters, such as code 7, BEL, which rings a terminal bell.
ISO 8601 is an international standard covering the worldwide exchange and communication of date and time-related data. It is maintained by the International Organization for Standardization (ISO) and was first published in 1988, with updates in 1991, 2000, 2004, and 2019, and an amendment in 2022. The standard provides a well-defined, unambiguous method of representing calendar dates and times in worldwide communications, especially to avoid misinterpreting numeric dates and times when such data is transferred between countries with different conventions for writing numeric dates and times.
The JPEG File Interchange Format (JFIF) is an image file format standard published as ITU-T Recommendation T.871 and ISO/IEC 10918-5. It defines supplementary specifications for the container format that contains the image data encoded with the JPEG algorithm. The base specifications for a JPEG container format are defined in Annex B of the JPEG standard, known as JPEG Interchange Format (JIF). JFIF builds over JIF to solve some of JIF's limitations, including unnecessary complexity, component sample registration, resolution, aspect ratio, and color space. Because JFIF is not the original JPG standard, one might expect another mime-type. However, it is still registered as "image/jpeg".
A decimal separator is a symbol used to separate the integer part from the fractional part of a number written in decimal form. Different countries officially designate different symbols for use as the separator. The choice of symbol also affects the choice of symbol for the thousands separator used in digit grouping.
UN/CEFACT is the United Nations Centre for Trade Facilitation and Electronic Business. It was established as an intergovernmental body of the United Nations Economic Commission for Europe (UNECE) in 1996 and evolved from UNECE's long tradition of work in trade facilitation which began in 1957.
In computer programming, Base64 is a group of binary-to-text encoding schemes that represent binary data in sequences of 24 bits that can be represented by four 6-bit Base64 digits.
Health Level Seven or HL7 is a range of global standards for the transfer of clinical and administrative health data between applications. The HL7 standards focus on the application layer, which is "layer 7" in the Open Systems Interconnection model. The standards are produced by Health Level Seven International, an international standards organization, and are adopted by other standards issuing bodies such as American National Standards Institute and International Organization for Standardization. There are a range of primary standards which are commonly used across the industry, as well as secondary standards which are less frequently adopted.
A comma-separated values (CSV) file is a delimited text file that uses a comma to separate values. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The use of the comma as a field separator is the source of the name for this file format. A CSV file typically stores tabular data in plain text, in which case each line will have the same number of fields.
ISO/IEC 6523Information technology – Structure for the identification of organizations and organization parts is an international standard that defines a structure for uniquely identifying organizations and parts thereof in computer data interchange and specifies the registration procedure to obtain an International Code Designator (ICD) value for an identification scheme.
JSON is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays. It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers.
In the C programming language, data types constitute the semantics and characteristics of storage of data elements. They are expressed in the language syntax in form of declarations for memory locations or variables. Data types also determine the types of operations or methods of processing of data elements.
ISO 8583 is an international standard for financial transaction card originated interchange messaging. It is the International Organization for Standardization standard for systems that exchange electronic transactions initiated by cardholders using payment cards.
ISO 2709 is an ISO standard for bibliographic descriptions, titled Information and documentation—Format for information exchange.
UN/CEFACT TBG5 is the entity responsible for financial services under the United Nations Centre for Trade facilitation and Electronic Business, (UN/CEFACT) under the United Nations Economic Commission for Europe (UNECE).
SDMX, which stands for Statistical Data and Metadata eXchange, is an international initiative that aims at standardising and modernising ("industrialising") the mechanisms and processes for the exchange of statistical data and metadata among international organisations and their member countries.
Tradacoms is an early standard for EDI primarily used in the UK retail sector. It was introduced in 1982 as an implementation of the UN/GTDI syntax, one of the precursors of EDIFACT, and was maintained and extended by the UK Article Numbering Association.
XML/EDIFACT is an Electronic Data Interchange (EDI) format used in Business-to-business transactions. It allows EDIFACT message types to be used by XML systems.
Data Format Description Language, published as an Open Grid Forum Recommendation in February 2021, is a modeling language for describing general text and binary data in a standard way. A DFDL model or schema allows any text or binary data to be read from its native format and to be presented as an instance of an information set.. The same DFDL schema also allows data to be taken from an instance of an information set and written out to its native format.
UNIDOC is an XML-based standard to support electronic data interchange (EDI) in business transactions between trading companies. Unlike other XML-based EDI formats, such as UBL, ebXML, RosettaNet or openTRANS, UNIDOC relies one a single structure. The first idea of such a universal format was published in 2014, its first specification in 2016 in the journal of the Chamber of Commerce and Industry Swabia . The current specification can be found in the UNIDOC XML Schema Definition.
