The Linked Open Data movement has been gaining traction for several years through promotion by Sir Tim Berners Lee, the W3C, among others including and members of the VIVO community active in the U.S. data.gov effort.
Try VIVO display web pages, but can also return the same information as data directly readable by other computers, locally or anywhere in the world. To see this in action, try browsing a VIVO page in a linked data browser such as LinkSailor, where the structure underlying the HTML display of the same data in VIVO can be clearly seen.
What does it mean to have VIVO serve linked data? VIVO data By fully complying with Linked Open Data standards, VIVO data is accessible, discoverable, reusable, and portable – all important factors given the work involved in gathering and maintaining making accurate and complete information about researchers and what they do visible to the world.
SPARQL endpoints
A number of VIVO institutions maintain public SPARQL endpoints – query points a Web address for querying data using the SPARQL query language against the VIVO triplestore, or VIVO's database of RDF. These SPARQL endpoints allow anyone to harvest not only the data about one person or other entity in VIVO but to run general-purpose queries.
Very often the goal in querying a VIVO is to extract RDF to include in another VIVO instance. The For example, the American Psychological Association , for example, queries VIVOs at several universities for updates on the authors of APA publication whose publication-related profiles are also maintained in publications in vivo.apa.org.
Dr. David Eichmann of the Institute for Clinical & Translational Science at the University of Iowa has built a CTSAsearch similar in concept to vivosearch.org but leveraging SPARQL endpoints as well as leverages SPARQL endpoints from four different software platforms to build a CTSAsearch extending the concept of vivosearch.org, which relies only on linked open data requests.
