Emerging Technologies and Associated Terminologies

URL also known as Universal Resource Identifier (URI) is used in reference to web pages in the address bar of a browser.32 Interchangeably, they are used to locate information resources on a computer network, and are always used in the context of web pages and hypertext transfer protocol (HTTP), such as www.rwpttp.com if RWPTPP becomes such a computer resource (a host) for integrated transportation services. To refer to a file name or an application, the URL address could be as: http://rwpttp.com/index.html. Here, index.html indicates a directory and a file reference.
Hypertext Transfer Protocol

However, the two schemas have been conceptually unified under the notion of Uniform Resource Identifier (URI; RFC 2396 and RFC 3986 [Berners-Lee, Fielding, and Masinter 1998, 2005]), and in practice it is common to use the term HTTP URI to actually refer to a HTTP URL. A URI is composed of at least two components, a scheme and an authority. The scheme component is case insensitive; however, it is common convention to use lowercase letters. The authority component is scheme dependent and may be case insensitive (noticeably in HTTP, where the authority is a domain name).
INTERconnected NETwork: Internet
Published in Akshi Kumar, Web Technology, 2018
More recently, a URL is now considered to be a subset of Uniform Resource Identifier (URI). A URI is a string of characters used to identify a name or a resource on the Internet and is recognized as a more general form of URL. It identifies a resource either by location, or a name, or both, i.e., a URI can be further classified as a locator, a name, or both. URL and URN (Uniform Resource Name) are two specializations of URI. Remember, every URL is a URI; every URN is a URI; URI and URL are NOT interchangeable—a URL is a URI, but a URI is not always a URL. We exemplify the three as follows: URL: Contains information about how to fetch a resource from its location. URLs always start with a protocol (http) and usually contain information such as the network host name (dtu.ac.in) and often a document path (/Academics/syllabus.php).For example: http://dtu.ac.in/Web/Academics/syllabus.phpftp://example.com/download.zipURN: Identifies a resource by a unique and persistent name. It usually starts with the prefix urn: URNs can be ideas and concepts. They are not restricted to identifying documents. When a URN does represent a document, it can be translated into a URL by a “resolver.” The document can then be downloaded from the URL.For example: urn: isbn: 0451450523 to identify a book by its ISBN number.URI: The URI encompasses URLs, URNs, and other ways to identify a resource. In a simple real-world analogy, a URN is a globally unique name, like ISBN # for a book. A URI is the identifier representing the contents of the book, and a URL is the location of the book.
Nomenclature for offsite construction

Names can be utilized to categorize, filter, identify, locate and communicate items, providing a feasible and straightforward way to manage information (Baca, 2016). A name is a word or set of words by which a person or thing is known, addressed, or referred to (Oxford University Press, n.d.). Names play a critical role in interpersonal communications, and there is much evidence that we value them in both the physical and digital worlds. In the physical world, when we know nothing about a certain thing, we instinctively obtain its name first. To meet such need, a nomenclature is a system for assigning names (Cambridge University Press, n.d.). For example, the International Union of Pure and Applied Chemistry nomenclature of organic chemistry provides a system for naming any possible organic compound according to its unambiguous structural formula (Connelly et al., 2005). Similar efforts include biological nomenclature (De Queiroz & Gauthier, 1994) and planetary nomenclature (Hargitai, 2006). In the digital era, information is extremely easy to create, copy and modify. Naming, or labelling information with nametags according to nomenclature rules, offers a means of handling the resulting exponential information growth for better communication and collaboration (Duval et al., 2002; Kang & Choi, 2015). Various nomenclature schemes have been proposed for this purpose, such as international standard book number (ISBN), digital object identifier (DOI) and uniform resource identifier (URI).
Efficiently identifying closed roads by integrating and indexing open data
Published in Journal of the Chinese Institute of Engineers, 2021

In addition to indexing, another field related to this research is open data. We integrate two sets of open data released by the government to build the system. A similar approach was also seen in the work done by Lv et al. (2018), which inferred the absent traffic congestion index (TCI) based on several sets of open data, such as the road network and points of interest. To let users easily understand the meaning of the open data and find their mutual interconnections, Křemen and Nečaský (2019) proposed the set of semantic government vocabularies to provide richer annotations. People also construct linked open data in which data on the web are interlinked using the standards such as URI (Uniform Resource Identifier) and HTTP (Hypertext Transfer Protocol). To monitor the evolution of linked open data, Blume and Scherp (2018) proposed an index in the schema level, which is maintained incrementally to avoid costly recomputations of the entire index when the data are updated. Since linked open data attracted a lot of attention and have been widely used, Yochum et al. (2020) provided a survey on how the linked open data have been used in location-based recommendation system particularly on the tourism domain.
Toward robot-agnostic home appliance operation: a task execution framework using motion primitives, ontology, and GUI

To describe pieces of the knowledge for home appliance operations, we adopt an ontology framework. Specifically, we use the Resource Description Framework (RDF)2 as one of the formal computer languages. The ontology consists of nodes and edges with the Uniform Resource Identifier (URI). We describe the information related to T, H, F, O, P, and A (See Equation (1)) in nodes and the relationships between each node in edges.
