A databin consists of a list of entries. Each entry contains metadata (such as timestamps and source information) together with actual data.
Data for each entry in a databin is typically organized in a key-value association
(with each key, for example, indicating a different quantity being measured):
(The data for each entry does not need to be a key-value association, but only key-value associations
support data semantics.)
Data values are internally stored in Wolfram Data Framework (WDF) using Wolfram Language symbolic expressions. Values are converted to WDF using the interpretations defined by the data semantics of a databin.
