Interface Description Language
interface description language or interface definition language (IDL), is a generic term for a language that lets a program or object written in one language communicate with another program written in an unknown language. IDLs describe an interface in a Language-independent specification, language-independent way, enabling communication between software components that do not share one language, for example, between those written in C++ and those written in Java (programming language), Java. IDLs are commonly used in remote procedure call software. In these cases the machines at either end of the ''link'' may be using different operating systems and computer languages. IDLs offer a bridge between the two different systems. Software systems based on IDLs include Sun Microsystems, Sun's ONC RPC, The Open Group's Distributed Computing Environment, IBM's System Object Model, the Object Management Group's CORBA (which implements OMG IDL, an IDL based on DCE/RPC) and Data Distributio ...

Language-independent Specification
A language-independent specification (LIS) is a programming language specification providing a common interface usable for defining semantics applicable toward arbitrary language bindings. LIS's are language-agnostic; they mitigate the risk that a certain language binding might reduce compatibility with other languages. An ideal LIS allows the language bindings to take advantage of features of a programming language uncompromisingly. Examples of LIS include Interface description language interface description language or interface definition language (IDL), is a generic term for a language that lets a program or object written in one language communicate with another program written in an unknown language.

Distributed Component Object Model
Distributed Component Object Model (DCOM) is a proprietary Microsoft technology for communication between software components on networked computers. DCOM, which originally was called "Network OLE", extends Microsoft's COM, and provides the communication substrate under Microsoft's COM+ application server infrastructure. The extension COM into Distributed COM was due to extensive use of DCE/RPC (Distributed Computing Environment/Remote Procedure Calls) – more specifically Microsoft's enhanced version, known as MSRPC. In terms of the extensions it added to COM, DCOM had to solve the problems of: * Marshalling – serializing and deserializing the arguments and return values of method calls "over the wire". *Distributed garbage collection – ensuring that references held by clients of interfaces are released when, for example, the client process crashed, or the network connection was lost. *Combining significant numbers of objects in the client's browser into a single transmi ...

Etch (protocol)
Etch was an open-source, cross-platform framework for building network services, first announced in May 2008 by Cisco Systems. Etch encompasses a service description language, a compiler, and a number of language bindings. It is intended to supplement SOAP and CORBA as methods of communicating between networked pieces of software, especially where there is an emphasis on portability, transport independence, small size, and high performance. Etch was designed to be incorporated into existing applications and systems, enabling a transition to a service-oriented architecture. It was derived from work on the Cisco Unified Application Environment, the product acquired by Cisco as part of the Metreos acquisition. History The mid-2008 release was planned to supported Java and C#. A second wave of support was supposed to include Ruby, Python, JavaScript, and C. In July 2008, Etch was released under the Apache 2.0 license. As part of the open source process, Etch was submitted to the A ...

Semantic Interoperability
Semantic interoperability is the ability of computer systems to exchange data with unambiguous, shared meaning. Semantic interoperability is a requirement to enable machine computable logic, inferencing, knowledge discovery, and data federation between information systems. Semantic interoperability is therefore concerned not just with the packaging of data (syntax), but the simultaneous transmission of the meaning with the data (semantics). This is accomplished by adding data about the data (metadata), linking each data element to a controlled, shared vocabulary. The meaning of the data is transmitted with the data itself, in one self-describing " information package" that is independent of any information system. It is this shared vocabulary, and its associated links to an ontology, which provides the foundation and capability of machine interpretation, inference, and logic. Syntactic interoperability (see below) is a prerequisite for semantic interoperability. Syntactic intero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JSON
JSON (JavaScript Object Notation, pronounced ; also ) 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 (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers. JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Any valid JSON file is a valid JavaScript (.js) file, even though it makes no changes to a web page on its own. Douglas Crockford originally specified the JSON format in the early 2000s. He and Chip Morningstar sent the first JSON message in April 2001. Naming and pronunciation The 2017 international standard (ECMA-404 and ISO/IEC 21778:2017) specifies "Pronounced , as in 'Jason and The ...

CBOR
Concise Binary Object Representation (CBOR) is a binary data serialization format loosely based on JSON authored by C. Bormann. Like JSON it allows the transmission of data objects that contain name–value pairs, but in a more concise manner. This increases processing and transfer speeds at the cost of human readability. It is defined in IETF . Amongst other uses, it is the recommended data serialization layer for the CoAP Internet of Things protocol suite and the data format on which COSE messages are based. It is also used in the Client-to-Authenticator Protocol (CTAP) within the scope of the FIDO2 project. CBOR was inspired by MessagePack, which was developed and promoted by Sadayuki Furuhashi. CBOR extended MessagePack, particularly by allowing to distinguish text strings from byte strings, which was implemented in 2013 in MessagePack. Specification of the CBOR encoding CBOR encoded data is seen as a stream of data items. Each data item consists of a header byte con ...

Apache Avro
Avro is a row-oriented remote procedure call and data serialization framework developed within Apache's Hadoop project. It uses JSON for defining data types and protocols, and serializes data in a compact binary format. Its primary use is in Apache Hadoop, where it can provide both a serialization format for persistent data, and a wire format for communication between Hadoop nodes, and from client programs to the Hadoop services. Avro uses a schema to structure the data that is being encoded. It has two different types of schema languages; one for human editing (Avro IDL) and another which is more machine-readable based on JSON. It is similar to Thrift and Protocol Buffers, but does not require running a code-generation program when a schema changes (unless desired for statically-typed languages). Apache Spark SQL can access Avro as a data source. Avro Object Container File An Avro Object Container File consists of: * A file header, followed by * one or more file dat ...

Apache Software Foundation
The Apache Software Foundation (ASF) is an American nonprofit corporation (classified as a 501(c)(3) organization in the United States) to support a number of open source software projects. The ASF was formed from a group of developers of the Apache HTTP Server, and incorporated on March 25, 1999. As of 2021, it includes approximately 1000 members. The Apache Software Foundation is a decentralized open source community of developers. The software they produce is distributed under the terms of the Apache License and is a non-copyleft form of free and open-source software (FOSS). The Apache projects are characterized by a collaborative, consensus-based development process and an open and pragmatic software license, which is to say that it allows developers who receive the software freely, to re-distribute it under nonfree terms. Each project is managed by a self-selected team of technical experts who are active contributors to the project. The ASF is a meritocracy, implying t ...

Java Native Interface
In software design, the Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly. Objectives JNI enables programmers to write native methods to handle situations when an application cannot be written entirely in the Java programming language, e.g. when the standard Java class library does not support the platform-specific features or program library. It is also used to modify an existing application (written in another programming language) to be accessible to Java applications. Many of the standard library classes depend on JNI to provide functionality to the developer and the user, e.g. file I/O and sound capabilities. Including performance- and platform-sensitive API implementations in the standard library allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
