By marking up information in standardized, highly structured formats like Resource Description Framework (RDF), we can allow computers to better "understand" the meaning of content

For most librarians this concept is fairly easy to understand. We have been creating highly structured machine-readable metadata for many years
-
By linking our data to shared ontologies that describe the properties and relationships of objects, we begin to allow computers not just to "understand" content, but also to derive new knowledge by "reasoning" about that content.
-
the term "Semantic Web" to refer to a full suite of W3C standards including RDF, SPARQL query language, and OWL web ontology language.
-
This article will outline some of the benefits that linked data could have for libraries, will discuss some of the non-technical obstacles that we face in moving forward, and will finally offer suggestions for practical ways in which libraries can participate in the development of the semantic web.
-
Having a common format for all data would be a huge boon for interoperability and the integration of all kinds of systems.
-
The linking hub would expose a network of tightly linked information from publishers, aggregators, book and journal vendors, subject authorities, name authorities, and other libraries.
-
semantic search could take us far beyond the current string-matching capabilities of search engines like Google.
-
Until there is enough linking between collections and imaginative uses of data collections there is a danger librarians will see linked data as simply another metadata standard, rather than the powerful discovery tool it will underpin.
-
Rights management poses potential problems for linked data in libraries. Libraries no longer own much of the content they provide to users; rather it is subscribed to from a variety of vendors.

-
The number of influential libraries publishing their metadata onto the web as linked open data, which is the heart of the Semantic Web, is growing
-
many librarians at major institutions have recognized that a key to the bibliographic future lies in migrating their data out of library silos and into an open, global pool of shared data.
-
the linked data cloud is seen as the most promising way to ensure that library data remains accessible and reusable

"If libraries are to retain their role as curators of the intellectual products of society, their assets must be part of that search stream."
-
libraries have begun to reconceptualize metadata and publish it on the web using linked data technologies, such as the Resource Description Framework (RDF) language and its extensions OWL, SKOS, and SPARQL.
-
library metadata is formatted and linked in RDF, then library content will surface more prominently in web search results
-
Recommendations from W3CThe report is still being finalized but the draft recommends that libraries:
-
— create web addresses using Uniform Resource Identifiers (URIs) as globally unique, web-compatible identifiers for the resources (any kind of object or concept) they manage and the metadata elements they use
-
— explore using libraries' ethos of quality control in the curation and long-term preservation of linked data datasets and vocabularies.
