GSOAP
gSOAP is a C and C++ software development toolkit for SOAP/XML web services and generic XML data bindings. Given a set of C/C++ type declarations, the compiler-based gSOAP tools generate serialization routines in source code for efficient XML serialization of the specified C and C++ data structures. Serialization takes zero-copy overhead. History The gSOAP toolkit started as a research project at the Florida State University by professor Robert van Engelen in 1999. The project introduced new methods for highly-efficient XML parsing (pull parsing) and serialization of C/C++ data directly in XML and later also in SOAP. The project succeeded at defining type-safe data bindings between XML Schema types and a wide variety of C/C++ data types. The toolkit uses automatic programming to simplify the development and invocation of Web services using efficient auto-generated XML serializers to send and receive C/C++ data directly. A domain-specific compiler-based tool generates source ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XML Data Binding
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. Description An XML data binder accomplishes this by automatically creating a mapping between elements of the XML schema of the document we wish to bind and members of a class to be represented in memory. When this process is applied to convert an XML document to an object, it is called unmarshalling. The reverse process, to serialize an object as XML, is called marshalling. Approaches to data binding can be distinguished as follows: * XML schema based: Based on an existing XML schema, classes that correspond to the schema are generated. * Class based: Based on a set of classes to be serialized, a corresponding XML schema is generated. * Mapping-based: A mapping description, usually itsel ...

WS-ReliableMessaging
WS-ReliableMessaging describes a protocol that allows SOAP messages to be reliably delivered between distributed applications in the presence of software component, system, or network failures. The original specification was written by BEA Systems, Microsoft, IBM, and Tibco and in March, 2003 and subsequently refined over the next two years. The February, 2005 version was submitted to the OASIS Web Services Reliable Exchange (WS-RX) Technical Committee in June of that year. The resultinWS-ReliableMessaging 1.1 was approved as an OASIS Standard on June 14, 2007, and v1.2 was approved on February 2, 2009. Prior to WS-ReliableMessaging, OASIS produced a competing standard (WS-Reliability) that was supported by a coalition of vendors; namely Fujitsu, Hitachi, NEC, Oracle Corporation, Progress Software, and Sun Microsystems. Most of these vendors now also support the WS-ReliableMessaging specification. Reliable Messaging Model An Application Source (AS) wishes to reliably send mess ...

Serialization
In computing, serialization (or serialisation) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different computer environment). When the resulting series of bits is reread according to the serialization format, it can be used to create a semantically identical clone of the original object. For many complex objects, such as those that make extensive use of references, this process is not straightforward. Serialization of object-oriented objects does not include any of their associated methods with which they were previously linked. This process of serializing an object is also called marshalling an object in some situations. The opposite operation, extracting a data structure from a series of bytes, is deserialization, (also called unserialization or un ...

WS-I Basic Profile
{{Short description, Interoperability guidance for core web services specifications The WS-I Basic Profile (official abbreviation is BP), a specification from the Web Services Interoperability industry consortium (WS-I), provides interoperability guidance for core Web Services specifications such as SOAP, WSDL, and UDDI. The profile uses Web Services Description Language (WSDL) to enable the description of services as sets of endpoints operating on messages. To understand the importance of WSI-BP, note that it defines a much narrower set of valid services than the full WSDL or SOAP schema. Many common platforms (listed below) support WSI-BP but do not support services outside of it. Compare the WSDL 1.1 specification to the subset permitted in WSI-BP. Also note that WSI-BP generally narrows the SOAP specification. There is a notable exception where WSI expands on the SOAP standard, and that is in adding xml:lang attribute on fault elements.

Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs, t ...

XML Validation
XML validation is the process of checking a document written in XML (eXtensible Markup Language) to confirm that it is both well-formed and also "valid" in that it follows a defined structure. A well-formed document follows the basic syntactic rules of XML, which are the same for all XML documents. A valid document also respects the rules dictated by a particular DTD or XML schema. Automated tools – validators – can perform well-formedness tests and many other validation tests, but not those that require human judgement, such as correct application of a schema to a data set. Standards * OASIS CAM is a standard specification that provides contextual validation of content and structure that is more flexible than basic schema validations. * Schematron, a method for advanced XML validation. Tools * '' xmllint'' is a command line XML tool that can perform XML validation. It can be found in UNIX / Linux Linux ( or ) is a family of open-source Unix-like operating syst ...

UDDI
Web Services Discovery provides access to software systems over the Internet using standard protocols. In the most basic scenario there is a ''Web Service Provider'' that publishes a service and a ''Web Service Consumer'' that uses this service. Web Service Discovery is the process of finding suitable web services for a given task. Publishing a web service involves creating a software artifact and making it accessible to potential consumers. Web service providers augment a service endpoint interface with an interface description using the Web Services Description Language (WSDL) so that a consumer can use the service. Universal Description, Discovery, and Integration (UDDI) is an XML-based registry for business internet services. A provider can explicitly register a service with a ''Web Services Registry'' such as UDDI or publish additional documents intended to facilitate discovery such as Web Services Inspection Language (WSIL) documents. The service users or consumers can s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WS-Discovery
Web Services Dynamic Discovery (WS-Discovery) is a technical specification that defines a multicast discovery protocol to locate services on a local network. It operates over TCP and UDP port 3702 and uses IP multicast address or . As the name suggests, the actual communication between nodes is done using web services standards, notably SOAP-over-UDP. Various components in Microsoft's Windows Vista operating system use WS-Discovery, e.g. "People near me". The component WSDMON in Windows 7 and later uses WS-Discovery to automatically discover WSD-enabled network printers, which show in Network in Windows Explorer, and can be installed by double-clicking on them. In Windows 8 or later installation is automatic. WS-Discovery is enabled by default in networked HP printers since 2008. WS-Discovery is an integral part of Windows Rally technologies and Devices Profile for Web Services. The protocol was originally developed by BEA Systems, Canon, Intel, Microsoft, and WebMethods.

WS-Addressing
Web Services Addressing (WS-Addressing) is a specification of transport-neutral mechanism that allows web services to communicate addressing information. It essentially consists of two parts: a structure for communicating a reference to a Web service endpoint, and a set of message addressing properties which associate addressing information with a particular message. Description WS-Addressing is a standardized way of including message routing data within SOAP headers. Instead of relying on network-level transport to convey routing information, a message utilizing WS-Addressing may contain its own dispatch metadata in a standardized SOAP header. The network-level transport is only responsible for delivering that message to a dispatcher capable of reading the WS-Addressing metadata. Once that message arrives at the dispatcher specified in the URI, the job of the network-level transport is done. WS-Addressing supports the use of asynchronous interactions by specifying a common SOA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WS-SecurityPolicy
WS-SecurityPolicy is a web services specification, created by IBM and 12 co-authors, that has become an OASIS standard as of version 1.2. It extends the fundamental security protocols specified by the WS-Security, WS-Trust and WS-SecureConversation by offering mechanisms to represent the capabilities and requirements of web services as policies. Security policy assertions are based on the WS-Policy framework. Policy assertions can be used to require more generic security attributes like transport layer security , message level security {{mono, <AsymmetricBinding> or timestamps, and specific attributes like token types. Most policy assertion can be found in following categories: * Protection assertions identify the elements of a message that are required to be signed, encrypted or existent. * Token assertions specify allowed token formats (SAML, X509, Username etc.). * Security binding assertions control basic security safeguards like transport and message level security, ...
