Details

  • In Databin["id"], id can be a short ID, a complete UUID, or a short or long URL.
  • The long URL for a databin in the Wolfram Cloud is of the form datadrop.wolframcloud.com/databin/.
  • Databin uses the standard sequence specification:
  • Allall entries
    nentries 1 through n
    -nlast n entries
    {n}entry n only
    {m,n}entries m through n inclusive
    {m,n,s}entries m through n in steps of s
  • Databin["id"] is equivalent to Databin["id",All].
  • In Databin["id",time], time is specified as a Quantity object.
  • Special forms for time include:
  • "Minute"most recent minute
    "Hour"most recent hour
    "Day"most recent 24-hour period
    "Week"most recent 7-day period
    "Month"most recent 30-day period
    "Year"most recent 365-day period
  • In Databin["id",date], date is specified using DateObject.
  • The following operations on databins are supported:
  • EventSeries[databin]an event series of all data in the databin
    TimeSeries[databin]a time series of all data in the databin
    Dataset[databin]a dataset of timestamps and entries in the databin
    Get[databin]the full content of the databin as a list of associations
    Normal[databin]the list of entries in the databin without metadata
    Values[databin]lists of values in the databin without timestamps
    Keys[databin]the association keys corresponding to the data signature
    DateListPlot[databin]time series plots for each key in the databin
    Options[databin]find the options of a databin
    SetOptions[databin,…]reset the options of a databin
    DeleteObject[databin]permanently delete a databin
  • In general, functions that operate on TimeSeries and EventSeries objects can be applied directly to Databin objects. Examples include Histogram, Mean, and TimeSeriesMap.
  • Operations can be performed on a databin using Databin[…][request,…].
  • Basic requests for retrieving databin content include:
  • "Latest"the latest entry added, with metadata
    "Recent"recent entries, with metadata
    "TimeInterval"timespan for entries in the databin
    "Timestamps"list of time stamps for all entries in the databin
    "GeoLocations"list of geo locations for all entries in the databin
    "EventSeries"event series for data in the databin (EventSeries)
    "TimeSeries"time series for data in the databin (TimeSeries)
    "FullEntries"all databin entries, with metadata (Get)
    "Entries"all entries in the databin, without metadata (Normal)
    "Values"list of values for each key used in the databin (Values)
    request,paramsmake a request with parameters params
  • Possible parameters params include:
  • seqentries given by the sequence specification seq
    <|key1val1,…|>detailed specification
  • Possible entries in the detailed specification include:
  • "StartIndex"index of first entry to include
    "EndIndex"index of last entry to include
    "StartTime"time of first entry to include
    "EndTime"time of last entry to include
  • Requests related to adding data to a databin include:
  • "Add",dataadd data to the databin
    "WebForm"cloud-deployed form for adding data to the databin
  • Databin["id"]["Add",data] is equivalent to DatabinAdd["id",data].
  • Databin["id"]["Add",data,"Authorization"->token] includes an authorization token, which must match a token specified when the databin was created.
  • Databin["id"]["Add",data,"Timestamp"date] includes a custom time stamp for a databin entry.
  • Databin identification operations include:
  • "ShortID"short ID for the databin
    "UUID"full UUID for the databin
    "ShortURL"short URL for the databin
    "URL"full UUID-based URL for the databin
    "Name"name assigned to the databin
  • Databin metadata requests include:
  • "Information"information about the databin
    "EntryCount"number of entries in the databin
    "Size"size of the databin contents
    "Keys"key names in the databin interpretation signature
    "LatestDate"date the latest entry was added
    "CreationDate"date the databin was first created
    "ExpirationDate"date the databin expires
    "Class"class used to create the databin
  • Databin["id"]["Keys"] is equivalent to Keys[Databin["id"]].

  • "Interpretation"interpretation signature for the databin
  • Databin access control operations include:
  • "Permissions"permissions for the databin
    "Owner"Wolfram ID of the owner of the databin
