The vivo.vivoweb.org site extends the standard ISF/VIVO ontology with a few classes and relationships to highlight VIVO installations and the typical range of skills needed to set up, populate, and maintain a VIVO instance (as discussed more in part 3 of this tour).

VIVO's not just another profiling system and not just people

...

VIVO is not just people profiles or the usual static mix of department and faculty web pages.  If you try .  Try a search for 'ontology' in our tour example and you'll see results about people, events, organizations, installations, and research. Each distinct type of entity represented in VIVO has its own attributes and relationships to others of itself or of other types, sometimes directly or sometimes through intermediate connections indicating roles or a time frame for the relationship. VIVO has to be able to change as people take on new projects, are promoted, or move to a different department or institution.

Making connections explicit

...

On most websites, the only way to find related items is to search for them and hope they share common terminology.  That works in VIVO too, as in searching for 'Pennsylvania', but notice when you click on any of the results, such as 'full public production', you'll see a links to other pages, including the University of Pennsylvania VIVO, that ensure relationships are pointed out and can be navigated in both directions.

...

Many users arrive at websites not by typing the URL but from a search engine that delivers them to any arbitrary page in the website having the keyword or content they searched. VIVO provides explicit connections to related items to help users understand context and minimize their need to immediately conduct another search.

Structured data

...

Because VIVO models data in a very granular way, it can be combined and reused more easily than web pages composed only of unstructured text and HTML markup.

A publication in VIVO is modeled not as one entity but as several – the article or book itself, a journal or publisher, each author, and additional objects representing the date of publication, editors or translators, and author order. Publications modeled individually rather than just embedded as text citations on a person's web page can be linked to each co-author and assembled into reports by journal, topic, academic department, research grant or facility, or time period.

Semantic data

...

VIVO is an example of an application built entirely with Semantic Web technologies promoted by the World Wide Web Consortium.
