    Network TAP Packet Broker for Metadata Out of band and Inline Network Monitoring


    Metadata, also known as intermediary data and relaying data, refers to data about data, which mainly describes information about property of data and is used to support functions such as indicating storage location, historical data, resource search, file recording and so on. Metadata is a kind of electronic directory, in order to achieve the purpose of cataloging, must describe and collect the content or characteristics of the data, and then to achieve the purpose of assisting data retrieval.Dublin Core set (Dublin Core Metadata Initiative, DCMI) is an application of the Metadata, was in February 1995 by the international library computer Center (OCLC) and the National Center for Supercomputing Applications (National Center for Supercomputing Applications, NCSA) have jointly sponsored seminars, inviting 52 from librarians, computer experts, jointly developing specifications, create a set of description on the network characteristics of electronic documents.

    Metadata is information about the organization of data, data domains, and relationships; in short, metadata is data about data.

    Metadata is defined as data that describes data, descriptive information about data and information resources.

    Metadata is data about other data, or structured data used to provide information about a resource.Metadata is the data that describes information resources or objects such as data.Evaluation of resources;Tracking changes in resource usage;Simple and efficient management of a large number of networked data;To realize the effective discovery, search and integration of information resources and effective management of resources.The basic characteristics of metadata are as follows:

    A) metadata, once established, can be Shared.The structure and integrity of metadata depend on the value and usage environment of information resources.Metadata development and utilization environment is always a changing and distributed environment.No one format can fully meet the needs of different groups;

    B) metadata is first and foremost a coding system.Metadata is used to describe the coding system of digital information resources, especially network information resources, which leads to the fundamental difference between metadata and traditional data coding system.The most important feature and function of metadata is to establish a machine-understandable framework for digitized information resources.

    The metadata system constructs the logical framework and basic model of e-government, which determines the functional characteristics, operation mode and overall performance of the system.The operation of e-government is based on metadata.Its main functions are: description function, integration function, control function and proxy function.

    Because metadata is data, it can be stored and retrieved in a database in a data-like manner.If the organization that provides the data element also provides the metadata that describes the data element, it will make the use of the data element accurate and efficient.When using data, users can first look at their metadata so that they can get the information they need.

    Data Warehouse

    In the data warehouse domain, metadata is divided into technical metadata and business metadata by purpose.First, metadata can provide user-based information, such as metadata that records business description information for data items to help users use the data.Secondly, metadata can support the system to manage and maintain the data. For example, metadata about the storage method of data items can support the system to access the data in the most efficient way.Specifically, in the data warehouse system, the metadata mechanism mainly supports the following five types of system management functions:

    (1) describe which data are in the data warehouse;

    (2) define the data to be entered into the data warehouse and the data generated from the data warehouse;

    (3) record the work schedule extracted from the data following the occurrence of business events;

    (4) record and test the requirements and implementation of system data consistency;

    (5) measure data quality.

    Software Construction

    Definition of the domain of software construction in the domain of software construction, metadata is defined as data that changes the behavior of a program by changing its value instead of being a processed object in the program.It plays an interpretive role in controlling program behavior during operation.By configuring metadata with different values at different places in the program, you get the same program behavior as before.

    Book information

    In the library and information world, metadata is defined as providing information about resources

    Metadata and library books

    Metadata and library books

    A structured form of data, a structured description of information resources.Its functions are: to describe the characteristics and attributes of information resources or data itself, to specify the organization of digital information, with functions such as location, discovery, proof, evaluation and selection.

    It is generally believed that metadata is data about data, or structured data about data.From the existing conclusions, the meaning of metadata is gradually developed.The term metadata, in the early stage, mainly refers to the descriptive data of network resources, used for the organization of network information resources;After that, it gradually expands to the description data of various information resources in electronic form.The term metadata is actually used to describe records of various types of information resources.

    In addition, metadata also has its corresponding definition and application in geography, life science and other fields.


    1. Metadata is structured data about data. It is not necessarily in digital form, but can come from different resources.

    2. Metadata is the data related to objects, which makes it unnecessary for potential users to have a complete understanding of the existence and characteristics of these objects.

    3. Metadata is the description of the code of the Information Package.

    4. Metadata contains a set of data elements used to describe the content and location of information objects, which promotes the discovery and retrieval of information objects in the network environment.

    5. Metadata not only describes information objects, but also describes the use environment, management, processing, storage and use of resources.

    6. Add metadata naturally to the life cycle of an information object or system.

    7. In the conventional definition of metadata, "data" refers to the symbol representing the transactional nature, the numerical value on which all kinds of statistics, calculations, scientific research and technical design are based, or the digitalized, formulated, coded and diagonalized information


    Metadata is key to a simpler programming model that no longer requires interface definition language (IDL) files, headers, or any external component reference methods.Metadata allows the.net language to describe itself automatically in a non-language-specific way that is invisible to both developers and users.In addition, metadata can be extended by using properties.Metadata has the following main advantages:

    Since the description

    Common language runtime modules and assemblies are self-describing.The metadata of a module contains all the information needed to interact with another module.Metadata automatically provides the functionality of IDL in COM, allowing a file to be used for both definition and implementation.Runtime modules and assemblies do not even need to be registered with the operating system.As a result, the instructions used by the runtime always reflect the actual code in the compiled file, thus improving the reliability of the application.


    Metadata provides all the necessary information about compiled code for you to inherit classes from PE files written in different languages.You can create instances of any class written in any managed language (any language for the common language runtime) without worrying about explicit marshaling or using custom interoperability code.


    The.net Framework allows you to declare certain kinds of metadata (called properties) in a compilation file.Properties are found throughout the.net Framework to more precisely control how your program works at runtime.In addition, you can send your own custom metadata to the.net Framework file through user-defined custom properties.For more information, see extending metadata with properties.



    The meaning of metadata can be explained in terms of its application purpose.Although it is necessary to call metadata as well as technical and business metadata when doing data warehouse, what is it used for?Leaving the target to talk about metadata, it turns out that metadata contains too much stuff because it's the data that describes the data.

    Still take the customer relationship system to compare, this system maintains the customer information certainly has the purpose, is to use this information to carry on some automatic process processing, to excavate some customer potential value, completes the customer service.Of course, there is no need to maintain vital information about customers, such as fingerprints and criminal history, which is not relevant to the goals of CRM.Metadata, you can take all of the data structure, size and what time to create, what time to die, is used by people, and so on, this information can be extended too wide, if regardless of the goal, and try to build a very perfect metadata management system, and this is an absolute "top-down" approach, to failure.
