DwC JQuery Client - Field View #49

Closed datadavev closed 13 years ago

datadavev commented 13 years ago

This is a new plugin that will show the characteristics of a single field within the Darwin Core Database.

The field view should show the field type, the total number of distinct terms, the minimum value, maximum value, and a rendering of the distinct terms based on their value and frequency of occurrence (e.g. word cloud or histogram).

The values should reflect the current active filter.

The Min/Max values present a slight problem. They are not shown in the original field view. We can potentially grab them from the /values or /histogram gateway function, however if we decide to implement a "top X" parameter in the values (which I think might be a good idea for word clouds with too many values), this might also pose a problem. Haven't given the solution much thought yet. What do you suggest?

Hi Corey, I found a "stats" module that provides useful information for continuous value fields. For example:

http://serrano.speciesanalyst.net/solr/select?indent=on&rows=0&stats=true&stats.field=mintemp_f&q=species_s:hexapterus

I'm undecided on whether the min and max values have any real meaning for string fields.

The field view should show values for the currently active filter. So record count, word cloud, histogram and other values should be modified by the current filter.
