A Formal PublicIdentifier FPI is a short piece of specially formatted text that may be used to uniquely identify a product, specification or document. One of their most common uses is as part of document type definitions, but they are also used in the vCard and iCalendar formats to identify the software product that has generated data. More recently, URI s and UUID s are usually used to uniquely identify objects. FPIs have become a legacy system . Syntax An example identifier code W3C DTD HTML 4.01 EN code can be broken down into two parts the owner identifier which indicates the issuer of the FPI, and the text identifier which indicates the particular document or object the FPI identifies ref http xml.coverpages.org tauber fpi.html ref . In the example, the owner identifier is code W3C code and the text identifier is code DTD HTML 4.01 EN code . The two parts are separated by a double Slash punctuation slash . Owner identifiers that are prefixed with code code indicate unregistered owners. W3C The W3C is notable for not having registered its FPI name. Registered identifiers are prefixed with code code and a small number of identifiers assigned by ISO do not require a prefix at all. Registered domain name s may be used as owner identifiers ref name ietf.org http www.ietf.org rfc rfc3151.txt ref .

In computer hypertext , a fragment identifier is a short Character string computer science string of character computing character s that refers to a resource computer science resource that is subordinate to another, primary resource. The primary resource is identified by a Uniform Resource Identifier URI , and the fragment identifier points to the subordinate resource. The fragment identifier introduced by a hash mark code code is the optional last part of a Uniform Resource Locator URL for a document. It is typically used to identify a portion of that document. The generic syntax is specified in RFC 3986. The number sign hash mark separator in URIs does not belong to the fragment identifier. Basics In URIs a hashmark code code introduces the optional fragment near the end of the URL. The generic RFC 3986 syntax for URIs also allows an optional query part introduced by a question mark code ? code . In URIs with a query and a fragment the fragment follows the query.

In the context of the Microsoft Windows NT line of operating system s, a Security Identifier commonly abbreviated SID is a unique, immutable identifier of a user, user group, or other security principle. A security principle has a single SID for life, and all properties of the principle, including its name, are associated with the SID. This design allows a principal to be renamed for example, from John to Jane , without affecting the security attributes of objects that refer to the principal. Overview Windows grants or denies access and privileges to resources based on access control list s ACLs , which use SIDs to uniquely identify users and their group memberships. When a user logs into a computer, an access token is generated that contains user and group SIDs and user privilege level. When a user requests access to a resource, the access token is checked against the ACL to permit or deny particular action on a particular object. SIDs are useful for troubleshooting issues with security audits, Windows server and domain migrations. The format of an SID can be illustrated using the following example S 1 5 21 3623811015 3361044348 30300820 1013 class wikitable border 1 S 1 5 21 3623811015 3361044348 30300820 1013 The string is a SID.

In computing , the process identifier normally referred to as the process ID or just PID is a number used by most operating system kernel computers kernel s such as that of Unix UNIX , Mac OS X or Microsoft Windows to temporarily uniquely identify a computer process process . This number may be used as a parameter in various function calls allowing processes to be manipulated, such as adjusting the process s priority or kill command killing it altogether. In Unix like operating systems, new processes are created by the code Fork operating system fork code system call . The PID is returned to the parent process parent enabling it to refer to the child in further function calls. The parent may, for example, wait for the child to terminate with the code waitpid code function, or terminate the process with code kill code . In Unix like operating systems, there are two tasks with specially distinguished process IDs swapper or sched has process ID 0 and is responsible for paging , and is actually part of the kernel rather than a normal user mode process. Process ID 1 is usually the init process primarily responsible for starting and shutting down the system. Originally, process ID 1 was not specifically reserved for init by any technical measures it simply had this ID as a natural consequence of being the first process invoked by the kernel. More recent Unix systems typically have additional kernel components visible as processes , in which case PID 1 is actively reserved for the init process to maintain consistency with older systems. Under Unix, process IDs are usually allocated on a sequential basis, beginning at 0 and rising to a maximum value which varies from system to system. Once this limit is reached, allocation restarts at 300 and again increases.

Context date March 2009 A Virtual Channel Identifier VCI is a unique identifier which indicates a particular virtual circuit on a network. It is a 16 bit field in the header of an Asynchronous transfer mode ATM cell. The VCI, together with the Virtual Path Identifier VPI is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination. ATM switches use the VPI VCI fields to identify the Virtual Channel Link VCL of the next network that a cell needs to transit on its way to its final destination. The function of the VCI is similar to that of the data link connection identifier DLCI in frame relay and the Logical Channel Number & Logical Channel Group Number in X.25 .

On the Internet , the Internationalized Resource Identifier IRI is a generalization of the Uniform Resource Identifier URI . While URIs are limited to a subset of the ASCII character set, IRIs may contain characters from the Universal Character Set Unicode ISO 10646 , including Chinese or Japanese kanji , Korean alphabet Korean , Cyrillic script Cyrillic characters, and so forth. It is defined by RFC 3987. Advantages There are reasons to see URIs displayed in different languages mostly, it makes it easier for users who are unfamiliar with the Latin A Z alphabet. Assuming that it isn t too difficult for anyone to replicate arbitrary Unicode on their keyboards, this can make the URI system more worldly and accessible. Disadvantages Mixing IRIs and ASCII Uniform Resource Identifier URI s can make it much easier to do phishing attacks that trick someone into believing they are on a site they really are not on. For example, one can replace the a in www. ebay .com or www. paypal .com with an internationalized look alike a character, and point that IRI to a malicious site. This is known as an IDN homograph attack . While a URI does not provide people with a way to specify Web resources using their own alphabets, an IRI does not make clear how Web resources can be accessed with keyboards that are not capable of generating the requisite internationalized characters.

In database design, a Persistent Object Identifier POID is a unique key unique identifier of a record on a table, used as the primary key . Important characteristics of a POID are that it does not carry business information and are not generally exported or otherwise made visible to data users as such a POID has many of the characteristics of a surrogate key . The only purpose of the POID is to act as the primary key on the table where it is defined and to be referenced as the foreign key by other tables. Because POIDs, like surrogate keys, do not carry business information, they are immune to changes in the form or meaning of business data.
