XML Linking Language (XLink) Version 11

XLink defines a set of attributes that may be added to elements of other XML namespaces. XLink provides two kinds of hyperlinking for use in XML documents. are out–of–band hyperlinks that, in a linkbase document, can link resources over which the link editor has no control. '''Simple links''' offer similar functionality to
HTML links, which are in–band links.
A is similar to those native to HTML; it simply creates a unidirectional
Hyperlink arc from one element to another via a
URI . Example:
Some Document
The Some Document header.
The XLink specification supports not only simple links but also . Extended links allow multiple resources, either remote or local, to be connected by multiple arcs. Arcs are explicitly unidirectional — they only define traversal in a single direction. By grouping resources with labels and using one or more arcs, an extended link can achieve specific traversal pathways among the resources.
For example, if all resources in an extended link were given the label
A, then an arc within that link which was
from="A", to="A" would connect every resource to every other resource and allow traversal from any of those resources to any other of those resources.
Extended links do not need to be contained in the same document as the elements they link to. This makes it possible to associate metadata or other supplemental information with resources without editing those resources.
XLink also supports richer information about link types and the roles for each resource that an XLink connects.
Software support for XLink, as of 2006 June, includes the following:
Mozilla Firefox (1.5.0) has very limited support for simple XLinks.
- Links with an
xlink:show="embed" attribute do not work.
- Links with an
xlink:actuate="onLoad" attribute work if they are the only thing on the page.
- All other links open the target in the current window, when requested, irrespective of the presence of
xlink:actuate or xlink:show attributes.
- In XML documents XLinks cannot be applied to elements in the XHTML namespace (Firefox 2.0)
Netscape (7.2) has the same support for simple XLinks as Firefox, except that the
xlink:show="new" attribute works correctly.

The XML language
RDDL , an extension to
XHTML Basic that is used to describe
XML Namespaces , uses XLink simple links.
The Extensible Business Reporting Language (
XBRL ) has used XLink simple and extended links since the XBRL 2.0 specification was published in 2001. Most large XBRL taxonomies contain extensive linkbases. As of 2006, XBRL is probably the most extensive use of XLink in production systems.
