<ext-link>

External Link

Link to an external file or resource.

Remarks

Use the standard XLink attributes to provide a live link to the external source.

The @ext-link-type attribute can be used to give an indication of the type of resource to which the external link points. While this Tag Set does not constrain the values of this attribute, and ordinary text is acceptable, the suggested values include:

ec

<self-uri> is used when an article is available in multiple forms, for example, as a means of indicating the online version of a print article. Conversely, a URI that indicates a different article or any other kind of external reference is usually tagged with <ext-link>. <uri>, although allowed everywhere <ext-link> is used, is more typically part of an address, information concerning a contributor, or part of a reference citation. Loosely put, an external link <ext-link> is intended to act as a link; a URI <uri> makes no promises but identifies a URI, such as a URL, when it is present in the text of an address or a citation; and <self-uri> points to another form of the same article (such as the PDF version of an online HTML article).

The address element <email> is allowed as part of a paragraph as well as inside an address. There are two ways to treat an email address in text: as an <email> element or as an <ext-link> element. If both a textual phrase (“the Moody Institute’s email address”) and a mailto URL are required, the <ext-link> element should be used.

The elements used in an address include the address class elements: <addr-line>, <country>, <fax>, <institution>, and <phone> and the address linking class elements: <email>, <ext-link>, and <uri>.
