Linked
Data?

Wikipedia says…
“Linked Data describes a method of publishing structured data, so that it can be interlinked
and become more useful. It builds upon standard web technologies, such as HTTP and URIs - but rather than using them to serve web pages for
human readers, it extends them to share information in a way that can be read
automatically by computers.”

We are used to connecting pieces of information based on their context.

Relationships are key.

Linked Data makes the
relationships explicit (to
computers!)

“Just as the traditional document Web can be crawled by following hypertext links, the Web of Data can be crawled by following RDF links. Working on the crawled data, search engines can provide sophisticated query capabilities... Because the query results themselves are structured data, not just links to HTML pages, they can be immediately processed, thus enabling a new class of applications based on the Web of Data.”
Chris Bizer, Richard Cyganiak, and Tom Heath

Web Visibility
“When my community searches the web for something we have, we better show up as an option.”

Privacy Concerns Related to Linked Data

There’s a lot more information out there
And it will be explored more aggressively

Libraries and Privacy
Photo credit: https://www.flickr.com/photos/pong/2404940312/
“Librarians feel a professional responsibility to protect the right to search for information free from surveillance. Privacy has long been the cornerstone of library services in America.Why? Because the freedom to read and receive ideas anonymously is at the heart of individual liberty in a democracy. Librarians defend that freedom every day.Libraries are information hubs for their communities. They are also natural centers for learning and talking about information issues… including privacy.”

Libraries, Rights Management,
and Linked Data

“Libraries no longer own much of the content they provide to users; rather it is subscribed to from a variety of vendors. Not only does that mean that vendors will have to make their data available in linked data formats for improvements to federated search to happen, but a mix of licensed and free content in a linked data environment would be extremely difficult to manage.”

“Data related to user identity and the use of the library is protected
by privacy policies and legislation.”
Privacy is a continuum.

Privacy Preference Ontology
Allows users to define “fine-grained privacy
preferences for restricting (or granting) access” to their information
Owen Sacco and Alexandre Passant
A Privacy Preference Ontology (PPO) for Linked Data http://events.linkeddata.org/ldow2011/papers/ldow2011-paper01-sacco.pdf
Ontology = Vocabulary
“Vocabularies are used to classify the terms
that can be used in a particular application, characterize possible relationships, and define possible constraints on using those terms.”
http://www.w3.org/standards/semanticweb/ontology
