Background on Exhibit
Exhibit was developed at MIT to provide a lightweight framework for the presentation, searching and faceted browsing of digital collections. Exhibit lets you easily create web pages with advanced text search and filtering functionalities, with interactive maps, timelines, and other visualizations
Little programming (JavaScript Template);
No database (JSON text);
a series of useful ‘instantly interactive’ visualisations.
So What?...

The Simplest View
Add Faceted BrowsingExplore data in context
Filter data by attributes
Faceted Browsing Code <div ex:role="facet" ex:expression=".discipline" ex:facetLabel="Discipline"></div>
<div ex:role="facet" ex:expression=".relationship" ex:facetLabel="Relationship"></div>
<div ex:role="facet" ex:expression=".shared" ex:facetLabel="Shared?"></div>
<div ex:role="facet" ex:expression=".deceased" ex:facetLabel="Deceased?"></div>
Add Search and Sort
Search Code
<div ex:role="facet" ex:facetClass="TextSearch"></div>
Add a Table View
Table Code<div
ex:role="exhibit-view”
ex:viewClass="Exhibit.TabularView” ex:columns=".label, .imageURL, .discipline, .nobel-year, .relationship-detail”
ex:columnLabels="name, photo, discipline, year, relationship with MIT”
ex:columnFormats="list, image, list, list, list”
ex:sortColumn="3”
ex:sortAscending="false">

Wrapup: ExhibitPros
Simple
Lightweight
No server required
A host of visualisations
Embeddable in other systems - ExhibitPress
ConsLimited Scalability
Some cross-browser issues
Restrictions on Look and Feel
Extensive customisation means getting into code
