XML Markup language developed by the W3C for encoding of data

Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The W3C's XML 1.0 Specification and several other related specifications—all of them free open standards—define XML.

C++ general purpose high-level programming language

C++ is a general-purpose programming language that was developed by Bjarne Stroustrup as an extension of the C language, or "C with Classes". It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation. It is almost always implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, Microsoft, Intel, and IBM, so it is available on many platforms.

Code Synthesis Tools CC is a software development company located in Cape Town, South Africa. The company revolves around the development and licensing of ODB, a compiler-based object-relational mapping (ORM) system for C++, CodeSynthesis XSD, an open-source, cross-platform XML Data Binding compiler for C++, and CodeSynthesis XSD/e, an open-source, validating XML parser/serializer generator and C++ XML Data Binding for mobile and embedded systems.

Given an XML instance specification (XML Schema), XSD/e can produce three kinds of C++ mappings: Embedded C++/Parser for event-driven XML parsing, Embedded C++/Serializer for event-driven XML serialization, and Embedded C++/Hybrid which provides a light-weight, in-memory object model on top of the other two mappings.

XSD, a recommendation of the World Wide Web Consortium (W3C), specifies how to formally describe the elements in an Extensible Markup Language (XML) document. It can be used by programmers to verify each piece of item content in a document. They can check if it adheres to the description of the element it is placed in.

The C++/Hybrid mapping generates C++ classes for types defined in XML Schema as well as parsing and serialization code. The C++ classes represent the data stored in XML as a statically-typed, tree-like object model and support fully in-memory as well as partially in-memory/partially event-driven XML processing. The C++/Parser mapping generates validating C++ parser skeletons for data types defined in XML Schema. One can then implement these parser skeletons to build a custom in-memory representation or perform immediate processing as parts of the XML documents become available. Similarly, the Embedded C++/Serializer mapping generates validating C++ serializer skeletons for types defined in XML Schema which can be used to serialize application data to XML.

CodeSynthesis XSD/e itself is written in C++ [1] and supports a number of embedded targets include Embedded Linux, VxWorks, QNX, LynxOS, iPhone OS and Windows CE.

Linux Family of free and open-source software operating systems based on the Linux kernel

Linux is a family of free and open-source software operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution.

VxWorks operating system

VxWorks is a real-time operating system (RTOS) developed as proprietary software by Wind River Systems, a wholly owned subsidiary of TPG Capital, US. First released in 1987, VxWorks is designed for use in embedded systems requiring real-time, deterministic performance and, in many cases, safety and security certification, for industries, such as aerospace and defense, medical devices, industrial equipment, robotics, energy, transportation, network infrastructure, automotive, and consumer electronics.

QNX Unix-like, real-time, embedded operating system

QNX is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market. The product was originally developed in the early 1980s by Canadian company Quantum Software Systems, later renamed QNX Software Systems and ultimately acquired by BlackBerry in 2010. QNX was one of the first commercially successful microkernel operating systems and is used in a variety of devices including cars and mobile phones.

A document type definition (DTD) is a set of markup declarations that define a document type for a SGML-family markup language.

SAX is an event-driven online algorithm for parsing XML documents, with an API developed by the XML-DEV mailing list. SAX provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model (DOM). Where the DOM operates on the document as a whole, i.e. building the full AST of an XML document for convenience of the user, SAX parsers operate on each piece of the XML document sequentially, issuing parsing events while making single pass through the input stream.

In computing, RELAX NG is a schema language for XML—a RELAX NG schema specifies a pattern for the structure and content of an XML document. A RELAX NG schema is itself an XML document but RELAX NG also offers a popular compact, non-XML syntax. Compared to other XML schema languages RELAX NG is considered relatively simple.

Extensible Application Markup Language is a declarative XML-based language developed by Microsoft that is used for initializing structured values and objects. It is available under Microsoft's Open Specification Promise. The acronym originally stood for Extensible Avalon Markup Language, Avalon being the code-name for Windows Presentation Foundation (WPF).

Java Architecture for XML Binding (JAXB) is a software framework that allows Java developers to map Java classes to XML representations. JAXB provides two main features: the ability to marshal Java objects into XML and the inverse, i.e. to unmarshal XML back into Java objects. In other words, JAXB allows storing and retrieving data in memory in any XML format, without the need to implement a specific set of XML loading and saving routines for the program's class structure. It is similar to xsd.exe and XmlSerializer in the .NET Framework.

XML data binding refers to a means of representing information in an XML document as a business object in computer memory. This allows applications to access the data in the XML from the object rather than using the DOM or SAX to retrieve the data from a direct representation of the XML itself.

An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints.

JSON text-based open standard designed for human-readable data interchange

In computing, JavaScript Object Notation (JSON) is an open-standard file format that uses human-readable text to transmit data objects consisting of attribute–value pairs and array data types. It is a very common data format used for asynchronous browser–server communication, including as a replacement for XML in some AJAX-style systems.

The Extensible Metadata Platform (XMP) is an ISO standard, originally created by Adobe Systems Inc., for the creation, processing and interchange of standardized and custom metadata for digital documents and data sets.

Core Data is an object graph and persistence framework provided by Apple in the macOS and iOS operating systems. It was introduced in Mac OS X 10.4 Tiger and iOS with iPhone SDK 3.0. It allows data organized by the relational entity–attribute model to be serialized into XML, binary, or SQLite stores. The data can be manipulated using higher level objects representing entities and their relationships. Core Data manages the serialized version, providing object lifecycle and object graph management, including persistence. Core Data interfaces directly with SQLite, insulating the developer from the underlying SQL.

XMLBeans is a Java-to-XML binding framework which is part of the Apache Software Foundation XML project.
