Interface Definition Language
An 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 are usually used to describe data types and interfaces in a language-independent way, for example, between those written in C++ and those written in 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'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 Distribution Service, Mozilla's XPCOM, Microsoft's Microsoft RPC (which evolved into COM and DCOM), Facebook's Thrift and WSDL fo ...

Microsoft RPC
Microsoft RPC (Microsoft Remote Procedure Call) is a modified version of DCE/RPC. Additions include partial support for UCS-2 (but not Unicode) strings, implicit handles, and complex calculations in the variable-length string and structure paradigms already present in DCE/RPC. Example The DCE 1.0 reference implementation only allows such constructs as , or possibly . MSRPC allows much more complex constructs such as and even , a common expression in DCOM IDL files. Use MSRPC was used by Microsoft to seamlessly create a client/server model in Windows NT, with very little effort. For example, the Windows Server domains protocols are entirely MSRPC based, as is Microsoft's DNS administrative tool. Microsoft Exchange Server 5.5's administrative front-ends are all MSRPC client/server applications, and its MAPI was made more secure by "proxying" MAPI over a set of simple MSRPC functions that enable encryption at the MSRPC layer without involving the MAPI protocol. History MSRPC is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CBOR
Concise Binary Object Representation (CBOR) is a binary data serialization format loosely based on JSON authored by Carsten Bormann and Paul Hoffman. Like JSON it allows the transmission of data objects that contain attribute–value pair, name–value pairs, but in a more concise manner. This increases processing and transfer speeds at the cost of Human-readable medium, 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 CBOR Object Signing and Encryption, COSE messages are based. It is also used in the Client to Authenticator Protocol, 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. ...

Concise Data Definition Language
In common usage and linguistics, concision (also called conciseness, succinctness, terseness, brevity, or laconicism) is a communication principle of eliminating redundancy,UNT Writing Lab. "Concision, Clarity, and Cohesion." Accessed June 19, 2012Link./ref> generally achieved by using as few words as possible in a sentence while preserving its meaning. More generally, it is achieved through the omission of parts that impart information that was already given, that is obvious or that is irrelevant. Outside of linguistics, a message may be similarly "dense" in other forms of communication. For example, a sentence of "It is a fact that most arguments must try to convince readers, that is the audience, that the arguments are true." may be expressed more concisely as "Most arguments must demonstrate their truth to readers." the observations that the statement is a fact and that readers are its audience are redundant, and it is unnecessary to repeat the word "arguments" in the sente ...

Protocol Buffers
Protocol Buffers (Protobuf) is a free and open-source cross-platform data format used to serialize structured data. It is useful in developing programs that communicate with each other over a network or for storing data. The method involves an interface description language that describes the structure of some data and a program that generates source code from that description for generating or parsing a stream of bytes that represents the structured data. Overview Google developed Protocol Buffers for internal use and provided a code generator for multiple languages under an open-source license. The design goals for Protocol Buffers emphasized simplicity and performance. In particular, it was designed to be smaller and faster than XML. Protocol Buffers is widely used at Google for storing and interchanging all kinds of structured information. The method serves as a basis for a custom remote procedure call (RPC) system that is used for nearly all inter-machine communication ...

Cap'n Proto
Cap’n Proto is a Serialization, data serialization format and Remote procedure call, Remote Procedure Call (RPC) framework for exchanging data between computer programs. The high-level design focuses on speed and security, making it suitable for network as well as inter-process communication. Cap'n Proto was created by the former maintainer of Google's popular Protocol Buffers framework (Kenton Varda) and was designed to avoid some of its perceived shortcomings. Technical overview IDL Schema Like most Remote Procedure Call, RPC frameworks dating as far back as Sun RPC and DCE/RPC, OSF DCE RPC (and their object-based descendants Common Object Request Broker Architecture, CORBA and Distributed Component Object Model, DCOM), Cap'n Proto uses an Interface description language, Interface Description Language (IDL) to generate RPC libraries in a variety of programming languages - automating many low level details such as handling network requests, converting between data types ...

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 f ...

Java Native Interface
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. Java 22 introduces the Foreign Function and Memory API, which can be seen as the successor to Java Native Interface. 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 capabil ...

Web Services Description Language
The Web Services Description Language (WSDL ) is an XML-based interface description language that is used for describing the functionality offered by a web service. The acronym is also used for any specific WSDL description of a web service (also referred to as a ''WSDL file''), which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns. Therefore, its purpose is roughly like a type signature in a programming language. The latest version of WSDL, which became a W3C recommendation in 2007, is WSDL 2.0. The meaning of the acronym has changed from version 1.1 where the "D" stood for "Definition". Description The WSDL describes services as collections of network Communication endpoint, endpoints, or Port (computer networking), ports. The WSDL specification provides an XML File format, format for documents for this purpose. The abstract definitions of ports and messages are separated from their conc ...
