Add custom metainformation to an image:
Image[[image], MetaInformation -> <|"Owner" -> "John"|>]Options[%]Import an image with metadata:
Import["ExampleData/coneflower.jpg"]Short[Options[%, MetaInformation], 2]Scope (3)
Store metainformation in an Image3D object:
Image3D[LinearGradientImage[{Red, Blue, Yellow}, {10, 10, 10}], MetaInformation -> <|"Owner" -> "John"|>]Options[%]Include additional metadata in TemporalData:
s = Accumulate[RandomInteger[{-5, 1}, 10]~Join~RandomInteger[{-1, 5}, 10]];td = TemporalData[s, {1, 20}, MetaInformation -> {"Event" -> 10}];The properties now include the metadata "Event":
td["Properties"]The added metadata can be used like any other property:
e = td["Event"]Show[ListLinePlot[td, PlotRange -> {Min[s] - 1, Max[s] + 1}], Graphics[{Red, PointSize[Large], Point[{e, td["PathFunction"][e]}]}]]Include additional metainformation in a TimeSeries object:
s = TimeSeries[FinancialData["SBUX", "Jan. 1, 2008"]]ts = TimeSeries[s, MetaInformation -> {"Stock" -> "SBUX"}]ts["MetaInformation"]Text
