Advanced Distributed Learning (ADL) is the product of the ADL Initiative, established in 1997 to standardize and modernize training and education management and delivery. The Department of Defense (DoD) Office of the Under Secretary of Defense for Personnel and Readiness (OUSD P&R) oversees the ADL Initiative. The vision of the ADL Initiative is to provide access to the highest-quality learning and performance aiding that can be tailored to individual needs and delivered cost-effectively, at the right time and in the right place. The ADL Initiative developed SCORM and the ADL Registry. ADL uses structured and collaborative methods to convene multi-national groups from industry, academia, and government who develop the learning standards, tools, and content.

In computing, a feed aggregator, also known as a feed reader, news reader, RSS reader or simply aggregator, is client software or a Web application which aggregates syndicated web content such as news headlines, blogs, podcasts, and vlogs in a single location for easy viewing. (Excerpt from Wikipedia article: Aggregation). See our disambiguation glossary for explanations of how 'Aggregation' is used in various contexts.

In mathematics and computer science, an algorithm is an effective method expressed as a finite list of well-defined instructions for calculating a function. Algorithms are used for calculation, data processing, and automated reasoning. In simple words an algorithm is a step-by-step procedure for calculations. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, will proceed through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input. (Excerpt from Wikipedia article: Algotithm)

Android is a software stack for mobile devices that includes an operating system, middleware and key applications. Google Inc. purchased the initial developer of the software, Android Inc., in 2005. Android's mobile operating system is based on a modified version of the Linux kernel. Google and other members of the Open Handset Alliance collaborated on Android's development and release. The Android Open Source Project (AOSP) is tasked with the maintenance and further development of Android. The Android operating system is the world's best-selling Smartphone platform.

An application programming interface (API) is a particular set of rules and specifications that a software program can follow to access and make use of the services and resources provided by another particular software program that implements that API. It serves as an interface between different software programs and facilitates their interaction, similar to the way the user interface facilitates interaction between humans and computers. (Excerpt from Wikipedia article: API)

An archive is a collection of historical records, or the physical place they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of an organization. In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost always unique, unlike books or magazines for which many identical copies exist. This means that archives (the places) are quite distinct from libraries with regard to their functions and organization, although archival collections can often be found within library buildings.

The name Atom applies to a pair of related standards. The Atom Syndication Format is an XML language used for web feeds, while the Atom Publishing Protocol (AtomPub or APP) is a simple HTTP-based protocol for creating and updating web resources. The Atom format was developed as an alternative to RSS. Ben Trott, an advocate of the new format that became Atom, believed that RSS had limitations and flaws - such as lack of on-going innovation and its necessity to remain backward compatible - and that there were advantages to a fresh design.Proponents of the new format formed the IETF Atom Publishing Format and Protocol Workgroup. The Atom syndication format was published as an IETF proposed standard in RFC 4287 (December 2005), and the Atom Publishing Protocol was published as RFC 5023 (October 2007).

Authentication is the act of confirming the truth of an attribute of a datum or entity. This might involve confirming the identity of a person, tracing the origins of an artifact, ensuring that a product is what its packaging and labeling claims to be, or assuring that a computer program is a trusted one. (Excerpt from Wikipedia article: Authentication)

In library and information science, bibliographic control (also known as information organization or bibliographic organization) is the process by which information resources are described so that users are able to find and select that information resource. An information resource could be a book, a movie, or an image, among other things. By providing a name, title, and subject access to the description, a bibliographic record is created. This bibliographic record, which is essentially metadata, is indexed by an information retrieval tool (such as a database or a search engine) so that a user can find out whether or not the information resource is relevant to them. (Excerpt from Wikipedia article: Bibliographic control)

In information technology, big data consists of datasets that grow so large that they become awkward to work with using on-hand database management tools. Difficulties include capture, storage, search, sharing, analytics, and visualizing. This trend continues because of the benefits of working with larger and larger datasets allowing analysts to "spot business trends, prevent diseases, combat crime." Though a moving target, current limits are on the order of terabytes, exabytes and zettabytes of data. Scientists regularly encounter this problem in meteorology, genomics, connectomics, complex physics simulations, biological and environmental research, Internet search, finance and business informatics. Data sets also grow in size because they are increasingly being gathered by ubiquitous information-sensing mobile devices, aerial sensory technologies (remote sensing), software logs, cameras, microphones, Radio-frequency identification readers, wireless sensor networks and so on." Every day, 2.5 quintillion bytes of data are created and 90% of the data in the world today was created within the past two years. (Excerpt from Wikipedia article: Big data)

A blog (a blend of the term web log) is a type of website or part of a website. Blogs are usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. Blog can also be used as a verb, meaning to maintain or add content to a blog. (Excerpt from Wikipedia article: Blog)

Web accessibility refers to the inclusive practice of making websites usable by people of all abilities and disabilities. When sites are correctly designed, developed and edited, all users can have equal access to information and functionality. For example, when a site is coded with semantically meaningful HTML, with textual equivalents provided for images and with links named meaningfully, this helps blind users using text-to-speech software and/or text-to-Braille hardware. When text and images are large and/or enlargable, it is easier for users with poor sight to read and understand the content. When links are underlined (or otherwise differentiated) as well as coloured, this ensures that color blind users will be able to notice them. When clickable links and areas are large, this helps users who cannot control a mouse with precision. When pages are coded so that users can navigate by means of the keyboard alone, or a single switch access device alone, this helps users who cannot use a mouse or even a standard keyboard. When videos are closed captioned or a sign language version is available, deaf and hard of hearing users can understand the video. When flashing effects are avoided or made optional, users prone to seizures caused by these effects are not put at risk. And when content is written in plain language and illustrated with instructional diagrams and animations, users with dyslexia and learning difficulties are better able to understand the content. When sites are correctly built and maintained, all of these users can be accommodated while not impacting on the usability of the site for non-disabled users.

A library catalog (or library catalogue) is a register of all bibliographic items found in a library or group of libraries, such as a network of libraries at several locations. A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc.) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library. (Excerpt from Wikipedia article: Library catalogue)

CERIF (Common European Research Information Format) emerged first as a simple standard not unlike a library catalogue card or the present DC (Dublin Core Metadata Standard) and was intended as a data exchange format. It was based on records describing projects, with persons and organisational units as attributes. However, it was soon realised that in practice this CERIF91 standard was inadequate: it was too rigid in format, did not handle repeating groups of information, was not multilingual / multi character set and did not represent in a sufficiently rich way the universe of interest. A new group of experts was convened and CERIF2000 was generated. Its essential features are: (a) it has the concept of objects or entities with attributes such as project, person, organisational unit; (b) it supports n:m relationships between them (and recursively on any of them) using 'linking relations' thus providing rich semantics including roles and time; (c) it is fully internationalised in language and character set; (d) it is extensible without prejudicing the core datamodel thus providing guaranteed interoperability at least at the core level but not precluding even richer intercommunication. It is designed for use both for data exchange (data file transfer) and for heterogeneous distributed query / result environments. With CERIF2004, minor improvements in consistency have been released. With CERIF2006 substantial improvements have been implemented with the model, concerning in particular the introduction of a so-called Semantic Layer, that makes the model flexible and scalable for application in very heterogeneous environments.
