Dear Interest Group,

we conducted a search for RDF data on the web. The results are summarized in
a technical report. The paper and the java/jdbc-based software that was used
is also available for download at:



The Resource Description Framework (RDF) allows describing metadata in an
interoperable way. It is the basis for promising work in the area of the
Semantic Web. This paper assesses how much and what kind of RDF data was
found on the web today. Four search strategies, crawling, scanning URLs
obtained from an Internet Directory, a targeted search, and a search at URLs
appearing in previously collected facts are described and compared. Results
show that RDF is currently hard to find unless a considerable effort and
resources are put into the search process.

Looking forward to hearing your comments, suggestions, or criticism.

Best regards

Andreas Eberhart
