Definition: Information that may be studied or analyzed to form conclusions.
Examples: Counts (specimens, people, particles);
Measurements (temperature, humidity, luminance);
Images (from satellites, x-rays, electron micrographs);
Time series (any of the above sampled over time);
Video, audio, seismograms, and other recordings.

Per NYT and IEEE usage, "data" can be used as a singular or plural noun as seems most appropriate in a particular context.

This is an important term, but I don't like the inconsistency in relationships between (data, datum) and (structured data, structured daturm). Here you put the full description and "datum" is only given as "singular of data". It's the opposite in the structured data case. If this were fixed, I'd give this a +1. Submitted 14 April 2016

Also, this is yet another instance where relations would be good. You could enumerate data's relationship to datum and structured datum. What do you think about a relation just being an informal description with a reference to a term? This could be easily done. Submitted 14 April 2016

I like the idea of informal, certainly to start. I'd like to see it in action. Submitted 14 April 2016

I just changed the definition dramatically, and realized that the vote didn't change. Maybe it should? Submitted 14 April 2016

Can we agree that data, as a plural of datum (perhaps equivalent to a data element) is a collection of datum? The model I'm seeing is that we have datum as the atomic level and everything else is various types of collections. Collections also exist at different levels of granularity. Submitted 14 April 2016

Examples of data:
1 Explicit statements/assertions of propositions in some language. In English: "this is a dog."

2. Values (names, numerals, strings, etc.) in some kind of
structures (tables, lists, graphs) together with some
schema (implicit or explicit) for interpreting the
structures of values as propositions. Pick your favorite spreasheet row as an example.

3. Values that have become detached from their explanations and
present a puzzle to be solved before they can be interpreted
as propositions. Stan/UNC/12-25-05 Is this a structure for somewhat being hired at a University? It is data but hard to interpret w/o the schema. (after Source John Sowa)

"Data" is plural of "Data"? Submitted 14 April 2016

Sensory input was meant to be "stuff that can be sensed". "Outputs" (eg, of processing) that can be sensed are therefore data. Stuff that can't be sensed can't be objects of analysis. Maybe the "Sensory input representing properties of things" should be shortened to just "Properties of things"? Submitted 14 April 2016
by John
I don't think I would agree with restricting data to "input", since data can be output. It is also not clear why data are "sensory" per se. I think of data as, primarily, objects of analysis. Submitted 14 April 2016
