Department Of Defense Discovery Metadata Specification
{{Redirect, DDMS, the Android debugger named Dalvik Debug Monitor Server, Dalvik (software) The Department of Defense Discovery Metadata Specification (DoD Discovery Metadata Specification or DDMS) is a Net-Centric Enterprise Services (NCES) metadata initiative. DDMS is loosely based on the Dublin Core vocabulary. DDMS defines discovery metadata elements for resources posted to community and organizational shared spaces. It is sometimes (incorrectly) referred to as ''DoD Discovery Metadata Standard''. The project focuses both on the process of developing a central taxonomy for metadata, and defining a way of discovering resources by their metadata using that taxonomy. The DDMS was created in support of the DoD Net-Centric Data Strategy (dated May 9, 2003), and specifies a set of information fields that are to be used to describe any data or service asset that is made known to the DoD Enterprise. The elements in the DDMS are designed to be platform, language, and implementation-ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Net-Centric Enterprise Services
Net-Centric Enterprise Services (NCES) is a Department of Defense program, managed by the Defense Information Systems Agency, to develop information technology infrastructure services for future systems used by the United States military. Technically, the program is based on the concept of 'enterprise integration' from the sub discipline enterprise engineering of systems engineering, which enables the transmission of right information at the right place and at the right time and thereby enable communication between people, machines and computers and their efficient co-operation and co-ordination. There are nine core enterprise services defined in the Network Centric Operations and Warfare - Reference Model (NCOW-RM): # storage # mediation # user assist # IA (Information Assurance) # ESM (Enterprise Service Management) # messaging # discovery & delivery # application # collaboration NCES maps these nine services to four product areas: # Enterprise service-oriented architectur ...

Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce st ...

Initiative
In political science, an initiative (also known as a popular initiative or citizens' initiative) is a means by which a petition signed by a certain number of registered voters can force a government to choose either to enact a law or hold a public vote in the legislature in what is called indirect initiative, or under direct initiative, where the proposition is put to a plebiscite or referendum, in what is called a ''Popular initiated Referendum'' or citizen-initiated referendum. In an indirect initiative, a measure is first referred to the legislature, and then put to a popular vote only if not enacted by the legislature. If the proposed law is rejected by the legislature, the government may be forced to put the proposition to a referendum. The initiative may then take the form of a direct initiative or an indirect initiative. In a direct initiative, a measure is put directly to a referendum. The vote may be on a proposed federal level, statute, constitutional amendment, cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dublin Core
220px, Logo image of DCMI, which formulates Dublin Core The Dublin Core, also known as the Dublin Core Metadata Element Set (DCMES), is a set of fifteen "core" elements (properties) for describing resources. This fifteen-element Dublin Core has been formally standardized as ISO 15836, ANSI/NISO Z39.85, and IETF RFC 5013. The Dublin Core Metadata Initiative (DCMI), which formulates the Dublin Core, is a project of the Association for Information Science and Technology (ASIS&T), a non-profit organization. The core properties are part of a larger set of DCMI Metadata Terms. "Dublin Core" is also used as an adjective for Dublin Core metadata, a style of metadata that draws on multiple Resource Description Framework (RDF) vocabularies, packaged and constrained in Dublin Core application profiles. The resources described using the Dublin Core may be digital resources (video, images, web pages, etc.) as well as physical resources such as books or works of art. Dublin Core metadata may ...

Data Element
In metadata, the term data element is an atomic unit of data that has precise meaning or precise semantics. A data element has: # An identification such as a data element name # A clear data element definition # One or more representation terms # Optional enumerated values Code (metadata) # A list of synonyms to data elements in other metadata registries Synonym ring Data elements usage can be discovered by inspection of software applications or application data files through a process of manual or automated Application Discovery and Understanding. Once data elements are discovered they can be registered in a metadata registry. In telecommunication, the term data element has the following components: #A named unit of data that, in some contexts, is considered indivisible and in other contexts may consist of data items. #A named identifier of each of the entities and their attributes that are represented in a database. #A basic unit of information built on standard structures h ...

Resource (computer Science)
In computing, a system resource, or simple resource, is any physical or virtual component of limited availability within a computer system. All connected devices and internal system components are resources. Virtual system resources include files (concretely file handles), network connections (concretely network sockets), and memory areas. Managing resources is referred to as resource management, and includes both preventing resource leaks (not releasing a resource when a process has finished using it) and dealing with resource contention (when multiple processes wish to access a limited resource). Computing resources are used in cloud computing to provide services through networks. Major resource types * Interrupt request (IRQ) lines * Direct memory access (DMA) channels * Port-mapped I/O * Memory-mapped I/O * Locks * External devices * External memory or objects, such as memory managed in native code, from Java; or objects in the Document Object Model (DOM), from JavaSc ...

Community
A community is a social unit (a group of living things) with commonality such as place, norms, religion, values, customs, or identity. Communities may share a sense of place situated in a given geographical area (e.g. a country, village, town, or neighbourhood) or in virtual space through communication platforms. Durable good relations that extend beyond immediate genealogical ties also define a sense of community, important to their identity, practice, and roles in social institutions such as family, home, work, government, society, or humanity at large. Although communities are usually small relative to personal social ties, "community" may also refer to large group affiliations such as national communities, international communities, and virtual communities. The English-language word "community" derives from the Old French ''comuneté'' (Modern French: ''communauté''), which comes from the Latin ''communitas'' "community", "public spirit" (from Latin '' communis'', "co ...

Organization
An organization or organisation (Commonwealth English; see spelling differences), is an entity—such as a company, an institution, or an association—comprising one or more people and having a particular purpose. The word is derived from the Greek word ''organon'', which means tool or instrument, musical instrument, and organ. Types There are a variety of legal types of organizations, including corporations, governments, non-governmental organizations, political organizations, international organizations, armed forces, charities, not-for-profit corporations, partnerships, cooperatives, and educational institutions, etc. A hybrid organization is a body that operates in both the public sector and the private sector simultaneously, fulfilling public duties and developing commercial market activities. A voluntary association is an organization consisting of volunteers. Such organizations may be able to operate without legal formalities, depending on jurisdiction, includ ...

XML Schema (W3C)
XSD (XML Schema Definition), a recommendation of the World Wide Web Consortium (W3C), specifies how to formally describe the elements in an Extensible Markup Language (XML) document. It can be used by programmers to verify each piece of item content in a document, to assure it adheres to the description of the element it is placed in. Like all XML schema languages, XSD can be used to express a set of rules to which an XML document must conform to be considered "valid" according to that schema. However, unlike most other schema languages, XSD was also designed with the intent that determination of a document's validity would produce a collection of information adhering to specific data types. Such a post-validation ''infoset'' can be useful in the development of XML document processing software. History XML Schema, published as a W3C recommendation in May 2001, is one of several XML schema languages. It was the first separate schema language for XML to achieve Recommendation stat ...

Trusted Data Format
The Trusted Data Format (TDF) is a data object encoding specification for the purposes of enabling data tagging and cryptographic security features. These features include assertion of data properties or tags, cryptographic binding and data encryption. The TDF is freely available with no restrictions and requires no use of proprietary or patented technology and is thus open for anyone to use. Overview The TDF Specification is based on a Trusted Data Object (TDO) which can be grouped together into a Trusted Data Collection (TDC). Each TDO consists of a data payload which can be associated with an unlimited number of metadata objects. The TDO supports the cryptographic binding of the metadata objects to the payload data object. In addition, both data and metadata objects can be associated with a block of encryption information which is used by any TDF consumer to decrypt the associated data or metadata if it had been encrypted. A TDC allows for additional metadata objects t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community Of Interest
A community of interest, or interest-based community, is a community of people who share a common interest or passion. These people exchange ideas and thoughts about the given passion, but may know (or care) little about each other outside this area. Participation in a community of interest can be compelling, entertaining and create a community where people return frequently and remain for extended periods. Frequently, they cannot be easily defined by a particular geographical area. In other words, "a community of interest is a gathering of people assembled around a topic of common interest. Its members take part in the community to exchange information, to obtain answers to personal questions or problems, to improve their understanding of a subject, to share common passions or to play." In contrast to a spatial community, "a 'community of interest' is defined not by space, but by some common bond (e.g. feeling of attachment) or entity (e.g. farming, church group)."
