(PDF) LITA 2010: The Linked Library Data Cloud: it's time to stop think and start linking

“Until very recently, bibliographic control has been an artisan activity, as there was no alternative for providing access except to transcribe, by hand, data from the objects being described. Now, however, publishers and vendors are working in an electronic environment, and print material generally originates in electronic format. ...Despite the fact that descriptive metadata are being created in other venues, libraries have so far taken minimal advantage of them. Given the explosion of material requiring some level of bibliographic control, the model of item-by-item full manual transcription can no longer be sustained. Libraries must find ways to make use of the data created by others in the supply chain, including data that can be derived from algorithmic analyses of digital materials.”

This won’t work with just

matching strings

Linked Data

1. Use URIs as names for things

2. Use HTTP URIs so that people can look up those names.

3. When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)

4. Include links to other URIs. so that they can discover more things.
