1.10: is display transformability of

Technical Implementation Notes

Formally, a character string is expected as an entry for this element.

It is expected that there will be local implementations of this element that invoke or use subelements that may use a nested approach. For example, one implementation using IEEE-LOM may use, 1.1 identifier, 1.1.1 catalog and 1.1.2 entry as a unique way to identify is display transformabilty of:

• isdisplaytransformabilityof

• 1.1 identifier

• 1.1.1 catalog

• 1.1.2 entry

Such an implementation may look like the following:

<identifier>

<catalog>URL</catalog> <entry>http://www.cancore.ca</entry>

</identifier>

A Dublin Core implementation would use the definition of identifier as, "An unambiguous reference to the resource within a given context". An example may look like, <dc:identifier rdf:resource="http://www.cancore.ca"/>

Vocabulary Recommendations

The recommended values are as follows:

URI Uniform Resource Identifier http://www.w3.org/Addressing/ A character string used to identify a resource (such as a file) from anywhere on the Internet by type and location (e.g., http://www.cancore.ca, ftp://www.ibm.com). The document "RFC2396" defines the generic syntax of URI, and provides guidelines for their use (see http://www.ietf.org/rfc/rfc2396.txt).

URL Uniform Resource Locator http://www.w3.org/Addressing/URL/Overview.html An informal name for addresses associated with the Web and other common Internet protocols (e.g., http://www.cancore.ca, ftp://129.128.193.212).

URN Uniform Resource Name http://www.ietf.org/rfc/rfc2141.txt "A particular scheme, urn:, specified by RFC2141 and related documents, intended to serve as persistent, location-independent, resource identifiers." (See http://www.w3.org/Addressing/). ISBNs may be incorporated or included here, for example, urn:isbn:xxx-xxx-xxx.

PURL Persistent Uniform Resource Locator http://purl.oclc.org/ Functionally, a PURL is a URL. However, instead of pointing directly to the location of an Internet resource, a PURL points to an intermediate resolution service. The PURL resolution service associates the PURL with the actual URL and returns that URL to the client. The client can then complete the URL transaction in the normal fashion. In other words, this is a standard HTTP redirect. PURLs satisfy many of the requirements of URNs, but they do not allow for complete location independence.

DOI Digital Object Identifier http://www.doi.org/ A system for identifying and exchanging intellectual property in a distributed, digital environment, developed in part by the Association of American Publishers. DOIs have been widely implemented in some contexts, including publishing and government, and are being considered by some educational infrastructure initiatives. DOI systems also provide some digital rights management features. Their use, however, may involve some upfront costs.
