International Standard Link Identifier

Last updated

The International Standard Link Identifier (ISLI), is an identifier standard. ISLI is a universal identifier for links between entities in the field of information and documentation. It was developed by the International Organization for Standardization (ISO) and published on May 15, 2015. ISO/TC 46/SC 9 is responsible for the development of the ISLI standard. [1]

Identifier name that identifies either a unique object or a unique class of objects

An identifier is a name that identifies either a unique object or a unique class of objects, where the "object" or class may be an idea, physical [countable] object, or physical [noncountable] substance. The abbreviation ID often refers to identity, identification, or an identifier. An identifier may be a word, number, letter, symbol, or any combination of those.

Contents

ISLI is used for identifying links between entities in the field of information and documentation. A linked entity can be physical, e.g. a print book or an electronic resource (text, audio, and video); or something abstract, e.g. a physical position within a frame of reference or the time of day.

In the context of modern information technology, the application of resources in the field of information and documentation is increasingly getting diversified. Isolated content products can no longer satisfy the ever-increasing user demand.

Information technology (IT) is the use of computers to store, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise. IT is considered to be a subset of information and communications technology (ICT). An information technology system is generally an information system, a communications system or, more specifically speaking, a computer system – including all hardware, software and peripheral equipment – operated by a limited group of users.

Documentation set of documents providing knowledge

Documentation is a set of documents provided on paper, or online, or on digital or analog media, such as audio tape or CDs. Examples are user guides, white papers, on-line help, quick-reference guides. It is becoming less common to see paper (hard-copy) documentation. Documentation is distributed via websites, software products, and other on-line applications.

Using a link identifier to build links between resources in the field of information and documentation provides a basis for a combined application of resources in the field, and supports collaborative creation of content and data interoperability between systems.

The openness of the ISLI system will boost the emergence of new applications in both multimedia and other fields, which increases the value of the linked-resources.

Multimedia is content that uses a combination of different content forms such as text, audio, images, animations, video and interactive content. Multimedia contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material.

The link model of ISLI includes three elements: a source, a target, and the link between them. A link identified by an ISLI code is unidirectional from the source to the target.

Format

An ISLI code consists of three parts: service code, link code and check digit. The service code comprises six decimal digits. The link code comprises decimal digits and its length is defined for each service. The check digit contains one decimal digit calculated from the service code and the link code. It is used for error detection.

Service Modeling Language(SML) and Service Modeling Language Interchange Format(SML-IF) are a pair of XML-based specifications created by leading information technology companies that define a set of XML instance document extensions for expressing links between elements, a set of XML Schema extensions for constraining those links, and a way to associate Schematron rules with global element declarations, global complex type definitions, and/or model documents. The SML specification defines model concepts, and the SML-IF specification describes a packaging format for exchanging SML-based models.

A check digit is a form of redundancy check used for error detection on identification numbers, such as bank account numbers, which are used in an application where they will at least sometimes be input manually. It is analogous to a binary parity bit used to check for errors in computer-generated data. It consists of one or more digits computed by an algorithm from the other digits in the sequence input.

A numerical digit is a single symbol used alone, or in combinations, to represent numbers according to some positional numeral systems. The single digits and their combinations are the numerals of the numeral system they belong to. The name "digit" comes from the fact that the ten digits of the hands correspond to the ten symbols of the common base 10 numeral system, i.e. the decimal digits.

Display

An ISLI code shall be shown in the format " ISLI XXXXXX-XXXXX-X". The hyphen is used for separating the three fields (service code, link code and check digit) and the word "ISLI" must be prefixed.

Administration

The ISLI system is administered by the ISLI Registration Authority (ISLI RA). And the International Information Content Industry Association (ICIA), a not-for-profit organization headquartered in Hong Kong, acts as the ISLI Registration Authority. ICIA is responsible for the maintenance of the ISLI system and other responsibilities specified in the ISLI standard.

Hong Kong East Asian city

Hong Kong, officially the Hong Kong Special Administrative Region of the People's Republic of China and commonly abbreviated as HK, is a special administrative region on the eastern side of the Pearl River estuary in southern China. With over 7.4 million people of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is the world's fourth most densely populated region.

Benefits

The ISLI standard provides a way of linking entities without changing the properties of those entities, e.g. ownership, access rights and identifiers that are used to identify those entities.

Obtaining a service code

To obtain a service code, the following procedures shall be followed: Decide the type of the specific link application. Search the list of link types in the ISLI RA Website to find the desired link type. Draw up the operational plan. Submit application for a service code, and specify the data access rights when registering metadata. Build the Service Provider Application and provide services to users.

Metadata data about data

Metadata is "data [information] that provides information about other data". Many distinct types of metadata exist, among these descriptive metadata, structural metadata, administrative metadata, reference metadata and statistical metadata.

Registration authorities exist for many standards organizations, such as ANNA, the Object Management Group, W3C, IEEE and others. In general, registration authorities all perform a similar function, in promoting the use of a particular standard through facilitating its use. This may be by applying the standard, where appropriate, or by verifying that a particular application satisfies the standard's tenants. Maintenance agencies, in contrast, may change an element in a standard based on set rules – such as the creation or change of a currency code when a currency is created or revalued. The Object Management Group has an additional concept of certified provider, which is deemed an entity permitted to perform some functions on behalf of the registration authority, under specific processes and procedures documented within the standard for such a role.

A payment card number, primary account number (PAN), or simply a card number, is the card identifier found on payment cards, such as credit cards and debit cards, as well as stored-value cards, gift cards and other similar cards. In some situations the card number is referred to as a bank card number. The card number is primarily a card identifier and does not directly identify the bank account number/s to which the card is/are linked by the issuing entity. The card number prefix identifies the issuer of the card, and the digits that follow are used by the issuing entity to identify the cardholder as a customer and which is then associated by the issuing entity with the customer's designated bank accounts. In the case of stored-value type cards, the association with a particular customer is only made if the prepaid card is reloadable. Card numbers are allocated in accordance with ISO/IEC 7812. The card number is usually prominently embossed on the front of a payment card, and is encoded on the magnetic stripe and chip, but may be imprinted on the back of the card.

Unicode input

Unicode input is the insertion of a specific Unicode character on a computer by a user; it is a common way to input characters not directly supported by a physical keyboard. Unicode characters can be produced either by selecting them from a display or by typing a certain sequence of keys on a physical keyboard. In addition, a character produced by one of these methods in one web page or document can be copied into another. Unicode is similar to ASCII but provides many more options and encodes many more signs.

ISO 7064 defines algorithms for calculating check digit characters.
