Available Formats:

• HTML - Plain HTML Format [URL: http://api.edna.edu.au/cloud.html]

Parameters:

• sr - Cloud data source [MANDATORY]
• cs - Number of tag classes [OPTIONAL, default: 7]
• tags - The total number of tags shown [OPTIONAL, default show all]
• th - frequency thresholds for tag classes [OPTIONAL, default: none]
  
  • A comma separated list of integers.
  • Must have cs+1 number of values. Each value represents the frequency threshold for the corresponding tag class. The last value represents the upper limit of the highest class.

  • Eg. cs=5&th=0,20,40,80,160,320 specifies 5 tag classes as follows:

    tag class	lower bound	upper bound
    tagSize1	0	19
    tagSize2	20	39
    tagSize3	40	79
    tagSize4	80	159
    tagSize5	160	320

Custom parameters:

• Arbitrary parameters required for specific cloud data source
• Eg. sr=foobar&foobar.report=2&foobar.size=20
• These custom parameters are supplied to the cloud-specific XSL, and optionally configurable to be passed to source URL.
