Link and URL tagging using EAD 2002

For linking between parts of large finding aids and to link to other finding aids for materials that are related by topic, originating agency, etc., use <archref> with the attribute href="..."

<archref> :Archival Reference
A reference element that provides a citation and/or an electronic link to separately described archival materials of special interest. Examples of such materials include a record group and one of its large series (which might have separate EAD-encoded finding aids) and a general reference to a collection with similar content.

The <archref> element can be helpful in several situations. Use the attribute HREF for linking to another EAD instance. The <archref> element can also be used to cite archival materials within a <bibliography>, <relatedmaterial>, or <separatedmaterial> element. The <archref> may contain just text or some of the content-specific elements such as <origination>, <repository>, and <unittitle> to identify the different kinds of information in a citation.

<archref href="http://www.lib.utexas.edu/taro/tslac/30022/30022.html" show="new" actuate="onrequest">Texas Adjutant General's Department, Reconstruction records, 1865-1873, undated, 7.87 cubic ft. </archref>

For linking to other pages or sites use <extref> with the attribute href="..."
(for example: use with links in repository)

<extref> :Extended Reference
A linking element that can include text and subelements as part of its reference to an electronic object that is external to the EAD document. Use the HREF attribute to identify the external object.

<extref href="http://www.tsl.state.tx.us/arc/service/index.html" show="new" actuate="onrequest"> http://www.tsl.state.tx.us/arc/service/index.html</extref>

<repository label="Repository" encodinganalog="852$a">
   <extref href="http://www.cah.utexas.edu/" show="new" actuate="onrequest">
     <corpname encodinganalog="852$a">
        <subarea>Center for American History,</subarea>
        The University of Texas at Austin

<dao> :Digital Archival Object
A linking element that uses the attribute HREF to connect the finding aid information to electronic representations of the described materials. The <dao> element allows digital representations including graphic images, audio or video clips, images of text pages, and electronic transcriptions of text to be incorporated in the finding aid.

Use the Extended Pointer <extptr> element to link the finding aid to electronic objects that are not part of the described materials.

EXAMPLE 1: For simple images that you just want to appear within the html use the following.....
<dao linktype="simple" href="http://imgs.ud.edu/archives/image/f12001_1.jpg" actuate="onload" show="embed"/>

EXAMPLE 2: For just a link to the image use "onrequest" for actuate instead of "onload" and "new" for show instead of "embed" (the link will be the href)
<dao linktype="simple" href="http://imgs.ud.edu/archives/image/f12001_1.jpg" actuate="onrequest" show="new"/>

EXAMPLE 3: If you want to a title instead of the link to display do the same as above but add a title
<dao linktype="simple" title="This is the title" href="http://imgs.ud.edu/archives/image/f12001_1.jpg" actuate="onrequest" show="new"/>

Linking Attributes to use for TARO collections:

A control that defines whether a link occurs automatically or must be requested by the user. It is used in conjunction with the SHOW attribute to determine link behavior. Values are:

  • onload (element is displayed automatically)
  • onrequest (element is displayed if user requests)
The locator for a remote resource in a simple or extended link. An HREF takes the form of a Uniform Resource Identifier (URI). If no URI is specified, the locator is assumed to be within the document that contains the linking element.
A control that defines whether a remote resource that is the target of a link appears at the point of the link, replaces the existing link, or appears in a new window. It is used in conjunction with the ACTUATE attribute to determine link behavior. Values are:

  • embed (the target resource displays at the point of the link)
  • new (the target resource appears in a new window)
  • replace (the target resource replaces the local resource that initiated the link)
Information that serves as a viewable caption which explains to users the part that a resource plays in a link..
