538     Benchmark for Faithful Digital Reproductions of Monographs and Serials. Version 1. December 2002 ‡i Digital version conforms to: ‡u http://www.diglib.org/standards/bmarkfin.htm
‡u Uniform Resource Identifier

The Uniform Resource Identifier (URI), for example a URL or URN, provides electronic access data in a standard syntax. Use this data for automated access to an electronic item using one of the Internet protocols. Repeat subfield if digital object has multiple identifiers (URIs).

538     Project methodology for digital version ‡i Technical details: ‡u http://www.columbia.edu/dlc/linglung/methodology.html

Substituting hexadecimal notation for diacritics and special characters in Uniform Resource Identifiers. When recording a URI in subfield ‡u, you may enter most of the spacing characters listed below as either characters or their hexidecimal equivalents. Consult the table below.

Note: Do not confuse the spacing characters listed below with their long-valid non-spacing counterparts. Use of the spacing characters will be limited almost exclusively to URLs.

Entry method Name Character Alternative entry (hex value)
Enter as character or hex value Spacing circumflex/circumflex accent ^ %5E
Spacing underscore/low line 1 _ %5F
Spacing grave/grave accent ` %60
Spacing tilde/tilde ~ %7E
Enter as hex value only vertical bar n/a %7C

1 Because the Spacing Underscore may cause problems with MARC output, users may prefer to continue entering it with the hexidecimal value %5F.
