There's no direct support for that, no. Backstage can import formats other than Exhibit JSON though. You can see the list here; https://github.com/zepheira/backstage/blob/master/modules/backstage/MOD-INF/src/edu/mit/simile/backstage/util/DataLoadingUtilities.java#L109 AIUI, it might also be possible to build a Sail adapter and hook in to the HostedDatabase class so that the database can be accessed directly, but that may require considerable effort. > > 2/ Performance > For my 250000 objects, the initial load of the site takes 2 minutes. > After that, about 10 secondes when i activate a filter.

The lifetime of the information that results from the initialization is tied to the servlet context, so you'll want to tweak that number carefully (in butterfly's web.xml). Performance after initialization will depend primarily upon your the number of facets, the size of the data in the faceted fields, and your users' network bandwidth. 250K is pretty large so you'll need to be careful. > > 3/ Carto > I need to use an OpenLayers facet for my project.

Sorry, there's no map view in Staged yet. Mark. -- You received this message because you are subscribed to the Google Groups "SIMILE Widgets" group.
