Fast Infoset
Fast Infoset (or FI) is an international standard that specifies a binary encoding format for the XML Information Set (''XML Infoset'') as an alternative to the XML document format. It aims to provide more efficient serialization than the text-based XML format. FI is effectively a lossless compression, analogous to ''gzip'', for XML, except that while the original formatting is lost, no information is lost in the conversion from XML to FI, and back to XML. While the purpose of compression is to reduce physical data size, FI aims to optimize both document size and processing performance. The Fast Infoset specification is defined by both the ITU-T and the ISO/IEC standards bodies. FI is officially defined in ''ITU-T Rec. X.891'' and ''ISO/IEC 24824-1,'' and entitled ''Fast Infoset''. The standard was published by ITU-T on May 14, 2005, and by ISO on May 4, 2007. The Fast Infoset standard document can be downloaded from thITU website Though the document does not assert intellect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary XML
Various binary formats have been proposed as compact representations for XML (''Extensible Markup Language''). Using a binary XML format generally reduces the verbosity of XML documents thereby also reducing the cost of parsing, but hinders the use of ordinary text editors and third-party tools to view and edit the document. There are several competing formats, but none has yet emerged as a ''de facto standard'', although the World Wide Web Consortium adopted EXI as a Recommendation on 10 March 2011. Binary XML is typically used in applications where the performance of standard XML is insufficient, but the ability to convert the document to and from a form (XML) which ''is'' easily viewed and edited is valued. Other advantages may include enabling random access and indexing of XML documents. The major challenge for binary XML is to create a single, widely adopted standard.

Open-source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts an ...

Apache Xerces
In computing, Xerces is Apache's collection of software libraries for parsing, validating, serializing and manipulating XML. The library implements a number of standard APIs for XML parsing, including DOM, SAX and SAX2. The implementation is available in the Java, C++ and Perl programming languages. The name "Xerces" is believed to commemorate the extinct Xerces blue butterfly (''Glaucopsyche xerces''). Xerces language versions There are several language versions of the Xerces parser: * Xerces2 Java, the Java reference implementation * Xerces C++, a C++ implementation * Xerces Perl, a Perl implementation. This implementation is a wrapper around the C++ API. Though technically marked active by Apache, there has been no major release in any language since 2010. Features The features supported by Xerces depend on the language, the Java version having the most features.

Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qt (software)
Qt (pronounced "cute") is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt. Qt is available under both commercial licenses and open-source GPL 2.0, GPL 3.0, and LGPL 3.0 licenses. Purposes and abilities Qt is used for developing graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a ''widget toolkit''. ...

Eclipse Metro
Metro is a high-performance, extensible, easy-to-use web service stack. Although historically an open-source part of the GlassFish application server, it can also be used in a stand-alone configuration. Components of Metro include: JAXB RI, JAX-WS RI, SAAJ RI, StAX (SJSXP implementation) and WSIT. Originally available under the CDDL and GPLv2 with classpath exception, it is now available under History Originally, the Glassfish project developed two semi-independent projects: *JAX-WS RI, the Reference implementation of the JAX-WS specification * WSIT, a Java implementation of some of the WS-* and an enhanced support for interoperability with the .NET Framework. It is based on JAX-WS RI as "Web Service layer". In June 2007, it was decided to bundle these two components as a single component named Metro. Features Metro compares well with other web service frameworks in terms of functionality. Codehaus started a comparison which compared Apache Axis 1.x, Axis 2.x, Celtix, G ...

JAX-WS
The Jakarta XML Web Services (JAX-WS; formerly Java API for XML Web Services) is a Jakarta EE Application programming interface, API for creating web services, particularly SOAP services. JAX-WS is one of the Java XML programming APIs. Overview The JAX-WS 2.2 specificatioJSR 224defines a standard Java- to-WSDL mapping which determines how Web Services Description Language, WSDL operations are bound to Java methods when a SOAP message invokes a WSDL operation. This Java-to-WSDL mapping determines which Java method gets invoked and how that SOAP message is mapped to the method’s parameters. This mapping also determines how the method’s return value gets mapped to the SOAP response. JAX-WS uses Java annotation, annotations, introduced in Java Platform, Standard Edition, Java SE 5, to simplify the development and deployment of web service clients and endpoints. It is part of the Java Web Services Development Pack. JAX-WS can be used in Java Platform, Standard Edition, Java SE st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base64
In computer programming, Base64 is a group of binary-to-text encoding schemes that represent binary data (more specifically, a sequence of 8-bit bytes) in sequences of 24 bits that can be represented by four 6-bit Base64 digits. Common to all binary-to-text encoding schemes, Base64 is designed to carry data stored in binary formats across channels that only reliably support text content. Base64 is particularly prevalent on the World Wide Web where one of its uses is the ability to embed image files or other binary assets inside textual assets such as HTML and CSS files. Base64 is also widely used for sending e-mail attachments. This is required because SMTP – in its original form – was designed to transport 7-bit ASCII characters only. This encoding causes an overhead of 33–37% (33% by the encoding itself; up to 4% more by the inserted line breaks). Design Each Base64 digit can take on 64 different values, encoding 6 bits of data. Which characters are chosen to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XML Information Set
XML Information Set (XML Infoset) is a W3C specification describing an abstract data model of an XML document in terms of a set of ''information items''. The definitions in the XML Information Set specification are meant to be used in ''other'' specifications that need to refer to the information in a well-formed XML document. An XML document has an information set if it is well-formed and satisfies the namespace constraints. There is no requirement for an XML document to be valid in order to have an information set. An information set can contain up to eleven different types of information items: #The Document Information Item (always present) #Element Information Items #Attribute Information Items # Processing Instruction Information Items #Unexpanded Entity Reference Information Items #Character Information Items #Comment Information Items #The Document Type Declaration Information Item #Unparsed Entity Information Items #Notation Information Items #Namespace Information Item ...

Abstract Syntax Notation One
Abstract Syntax Notation One (ASN.1) is a standard interface description language for defining data structures that can be serialized and deserialized in a cross-platform way. It is broadly used in telecommunications and computer networking, and especially in cryptography. Protocol developers define data structures in ASN.1 modules, which are generally a section of a broader standards document written in the ASN.1 language. The advantage is that the ASN.1 description of the data encoding is independent of a particular computer or programming language. Because ASN.1 is both human-readable and machine-readable, an ASN.1 compiler can compile modules into libraries of code, codecs, that decode or encode the data structures. Some ASN.1 compilers can produce code to encode or decode several encodings, e.g. packed, BER or XML. ASN.1 is a joint standard of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) in ITU-T Study Group 17 and ISO/IEC, orig ...

Encoding Control Notation
The Encoding Control Notation (ECN) is a standardized formal language that is part of the Abstract Syntax Notation One (ASN.1) family of international standards. ECN is designed to be used along with ASN.1, and each ECN specification (a coherent set of encoding definitions) is explicitly related to a particular ASN.1 specification (a coherent set of type definitions). The ECN standard is published by both the ITU-T and the ISO ISO is the most common abbreviation for the International Organization for Standardization. ISO or Iso may also refer to: Business and finance * Iso (supermarket), a chain of Danish supermarkets incorporated into the SuperBest chain in 2007 * Iso ..., and is officially named ''ITU-T Recommendation X.692 , ISO/IEC 8825-3, Information technology – ASN.1 encoding rules: Specification of Encoding Control Notation (ECN)''. ECN supports the formal specification of non-standard encoding rules for ASN.1 type definitions, and is intended to be used whenever it ...
