These different XRIs that all point to the same resource are called synonyms.

XRIs are also backwards compatible with the DNS and IP addressing systems, so it is possible for domain names and IP addresses to be used as i-names ( or, in rare cases, as i-numbers ).

I-names are human readable XRIs intended to be as easy as possible for people to remember and use.

One problem XRIs are designed to solve is persistent addressing — how to maintain an address that does not need to change no matter how often the contact details of a person or organization change.

OpenID also supports XRIs, and XRIs are the basis for i-names.

Starting with OpenID Authentication 2. 0 ( and some 1. 1 implementations ), there are two types of identifiers that can be used with OpenID: URLs and XRIs.

XRIs are a new form of Internet identifier designed specifically for cross-domain digital identity.

For example, XRIs come in two forms — i-names and i-numbers — that are usually registered simultaneously as synonyms.

Note that they do not include the xri :// prefix as this is optional with absolute XRIs.

XRIs accomplish this by adding a third layer of abstract addressing over the existing layers: IP numbering ( first layer ) and DNS naming ( second layer ).

Like DNS names, XRIs can also be delegated, i. e., nested multiple levels deep, just like the directory names on a local computer file system.

XRIs accomplish this by adding a new layer of abstraction over the existing IP numbering and DNS naming layers used on the Internet today ( as well as over other type of addresses, such as phone numbers or instant messaging addresses ).

Like DNS names, XRIs can also be " delegated ", i. e., nested multiple levels deep, just like the directory names on a local computer file system.

An identity provider, or OpenID provider ( OP ) is a service that specializes in registering OpenID URLs or XRIs.

* XDI — XRI Data Interchange, a standard for sharing, linking, and synchronizing data (" dataweb ") across multiple domains and applications using XML documents, eXtensible Resource Identifiers ( XRIs ), and a new method of distributed data control called a link contract.

Later versions in each branch are backward-compatible with earlier versions ( aside from non-conformant RDF syntax in 0. 90 ), and both versions include properly documented extension mechanisms using XML Namespaces, either directly ( in the 2.

To support the new features, especially typographic, introduced with InDesign CS, both the program and its document format are not backward-compatible.

x86 assembly language is a family of backward-compatible assembly languages, which provide some level of compatibility all the way back to the Intel 8008. x86 assembly languages are used to produce object code for the x86 class of processors, which includes Intel's Core series and AMD's Phenom and Phenom II series.

DNSSEC was designed to be extensible so that as attacks are discovered against existing algorithms, new ones can be introduced in a backward-compatible fashion.

Cameras supporting the EF-S mount are backward-compatible with the EF lens mount and, as such, have a flange focal distance of 44. 0 mm.

GL-5 is not necessarily backward-compatible in synchro-mesh transmissions which are designed for a GL-4 oil: GL-5 has a lower coefficient of friction due to the higher concentration of EP additives over GL-4, and thus synchros can not engage as effectively.

USB OTG devices are backward-compatible with USB 2. 0 ( USB 3. 0 for SuperSpeed OTG devices ) and will behave as standard USB hosts or devices when connected to standard ( non-OTG ) USB devices.

this is not so, for education offers all kinds of dividends, including how to pull the wool over a husband's eyes while you are having an affair with his wife.

And, as a matter of fact, Nicolas had slept in the park only part of one night, when he discovered that Munich's early mornings even in summer are laden with dew.

All the drivers knew about the plates and they also knew about the big floppy straw hat with shredded edges, the kind natives in travel ads wear when they are out joyfully chopping cane.

For a brief period each year, the rays of the sun are warm enough to melt some of the snows piled a mile deep at the base of the headwalls, and then the pinnacles glisten in the daytime at high noon, and billions of gallons of water begin their slow seepage under the glaciers and across the rockstrewn hanging valleys on their long, meandering journey to the sea -- running east past the sky-carving massifs of Gurla Mandhata and Kemchenjunga, then turning south and curling down through the jungles of Assam, past the Khasi Hills, and into Bengal, past Sirinjani and Madaripur, until the hard water of the melting snows mingles with the soft drainage of fields and at length fans out to meld with the teeming salt depths of the Bay of Bengal.

Really, you are most indiscreet to drive him here yourself '', he said, frowning with displeasure.

High-level abstractions are always difficult to pin down with precision.

I have just asked these questions in the Pentagon, in the White House, in offices of key scientists across the country and aboard the submarines that prowl for months underwater, with neat rows of green launch tubes which contain Polaris missiles and which are affectionately known as `` Sherwood Forest ''.

Only one rule prevailed in my conversations with these men: The more highly placed they are -- that is, the more they know -- the more concerned they have become.

Movable panels of floor-to-ceiling maps and charts are crammed with intelligence information.

They are huge areas which have been swept by winds for so many centuries that there is no soil left, but only deep bare ridges fifty or sixty yards apart with ravines between them thirty or forty feet deep and the only thing that moves is a scuttling layer of sand.

On Fridays, the day when many Persians relax with poetry, talk, and a samovar, people do not, it is true, stream into Chehel Sotun -- a pavilion and garden built by Shah Abbas 2, in the seventeenth century -- but they do retire into hundreds of pavilions throughout the city and up the river valley, which are smaller, more humble copies of the former.

Those three other great activities of the Persians, the bath, the teahouse, and the zur khaneh ( the latter a kind of club in which a leader and a group of men in an octagonal pit move through a rite of calisthenics, dance, chanted poetry, and music ), do not take place in buildings to which entrance tickets are sold, but some of them occupy splendid examples of Persian domestic architecture: long, domed, chalk-white rooms with daises of turquoise tile, their end walls cut through to the orchards and the sky by open arches.

Water, air, fruit, poetry, music, the human form -- these things are important to Persians, and they experience them with an intense and discriminating awareness.

Nostalgic Yankee readers of Erskine Caldwell are today informed by proud Georgians that Tobacco Road is buried beneath a four-lane super highway, over which travel each day suburbanite businessmen more concerned with the Dow-Jones average than with the cotton crop.

The effects of television and other mass media are erasing regional dialects and localisms with a startling force.

The fumes of progress are in his nose and the bright steel of industry towers before his eyes, but his heart is away in Yoknapatawpha County with razorback hogs and night riders.

An earlier but still influential school of painting, surrealism, had suggested the way of dealing with the dream experience, that event in which seemingly incongruous objects are linked together through the curious associations of the subconscious.

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

They recognized that slavery was a moral issue and not merely an economic interest, and that to recognize it explicitly in their Constitution would be in explosive contradiction to the concept of sovereignty they had set forth in the Declaration of 1776 that `` all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among them are life, liberty and the pursuit of happiness.

Lucretius has remarked: `` The reason why all Mortals are so gripped by fear is that they see all sorts of things happening in the earth and sky with no discernable cause, and these they attribute to the will of God ''.
