-==About==
+[[category:moved]]
-[[DataFerret]] is a way to store arbitrary data from multiple sources in a single database.
+moved to [https://wooz.dev/FactFerret wooz.dev]
-The purpose is to allow multi-layered querying (e.g. "display rate of all A that didn't include B from year C to year D") without foreknowledge of what data is available. This is in some ways similar to what [http://gapminder.com GapMinder] does, except it should be relatively easy to add new datasets (one database schema should be able to accommodate any assertion of fact) and it should be capable of data-dependent conditionals ("all A that didn't include B" is just a very simple example).
-It also bears some similarity to Semantic MediaWiki, except that data is entered and updated independently of a wiki page, via both manual and automated methods.
-==Schema==
-This is a preliminary schema, just to give an idea of how it works.
-'''point'''
-* ID (auto)
-* ID_Series
-'''value'''
-* ID (auto)
-* ID_Axis
-'''series_attrib'''
-* ID (auto)
-* ID_Series
-* ID_Attrib
-* Value
-'''axis'''
-* ID (auto)
-* ID_Series
-* Name
-* ID_Unit
-'''series'''
-* ID (auto)
-* Name
-* Descrip
-* ID_Source
-* ''possibly other attributes''
-'''source'''
-* ID (auto)
-* ID_Entity -- organization or individual who created the data
-* URL -- (optional) web page where data may be found
-* When_Retrieved
-'''unit'''
-* ID (auto)
-* Name
-* ID_Handler -- sprintf(), date(), custom code...
-'''unit_format'''
-* ID (auto)
-* ID_Unit
-* Name -- a name for the format, e.g. "ISO xxxx"
-* Tplt -- template string to pass to unit handler (e.g. "%y/%m/%d")
-==Views==
-* Represent any 2 axes as a graph/chart -- basically, spreadsheet graphing functionality:
-** variety of graph/chart formats available
-** eventually, add more dimensions (color, size, slider) a la GapMinder
-** restrict [[wikipedia:Range (computer programming)|range]] or show entire range
-* Answer questions written in English-like syntax, with graphs or scalars:
-** "During the 2008 mortgage crisis, what percent of loan defaults came from CRA-inspired loans?" (scalar output)
-** "Display rate of default for CRA-inspired loans versus all loans during the 2008 mortgage crisis." (graph output, restricted range)
-** "Display {profitability of loans to minorities} and {profitability of loans overall} by year." (graph output, unrestricted range)
-* Offer sources for all data presented.
-* Where data from multiple sources differs: offer to average it, present each source separately, or show each source separately in the output (e.g. as a differently-colored line).
