Metadata Analysis Of JISC 5/99 Project Entry Points

A pilot survey of the availability of Dublin Core metadata on the home pages of JISC 5/99 projects has been carried out. The survey makes use of the W3C's Dublin Core Extraction Service and the online Tidy service.

This survey provides a link to the W3C's Dublin Core Extraction Service for each project. This will return the Dublin Core metadata in RDF format which is extracted using an XSLT transformation of an XHTML resource.

If the resource is in HTML format and not HTML it will be necessary to transform the HTML page into XHTML. This survey provides a link to the W3C's Dublin Core Extraction Service for each project in which the input data is a XHTML version of the resource, which has been converted on-the-fly using the online Tidy service.

This Dublin Core metadata is returned in RDF format. If you are using a recent version of Internet Explorer, this should be displayed as an XML resource (as shown in Figure 1). If you are using other browsers you should see the metadata displayed as unformatted text.

The RDF representation of the Dublin Core metadata can be copied and pasted into the W3C's RDF Validator, as illustrated below.

Figure 2: Visualisation Of Dublin Core Metadata

On 27^th November 2002 the survey was updated with a report on the validity of Dublin Core metadata. This was obtained used the DC-dot. The findings are available in the final two columns.

A summary of the findings is given in the following table. The data was taken from the listing of DNER Development Projects.

Notes

Please note the following:

• Only the projects with a Web site have been analysed.
• Only the entry points have been analysed.
• Only an automated analysis has been carried out.
