developer.inlineData

Purpose: explore URI syntax for containing data, inparticular to support plotting in javascript with an applet. For example, a yagi calculator calculates element dimensions, then autoplot in an applet is used to display the antenna layout. Also, SeriesRenderer is given a rank 0 number so that a reference line is drawn.

This also forces a clean-up of the datasources API, which still uses URLs, excluding databases and this simple use case.

Limitations. It looks like many servers have a limit of 256 characters. I couldn't find any limitations in the URI spec. For large datasets, another mechanism should be used.

Use Cases

• In jython, construct dataset ytags with inline dataset.

 ytags= getDataSet( 'vap+inline:exp(findgen(20))&UNITS=eV&SCALE_TYPE=log&LABEL=Energy' )

• Decorate existing datasets. This removes the xtags from the dataset (not released):

 vap+inline:getDataSet('`<http://autoplot.org/data/autoplot.cdf?BGSM>`')&DEPEND_0=None
