Annette,

I've been doing some thinking about this,  What do you think of this:

Eric S

Original Why:

The presence of real-time data on the web enables access to critical time
sensitive data, and encourages the development of real-time web
applications. Real-time access is dependent on real-time data producers
making their data readily available to the data publisher. In addition to
making pubished data accessible, data publishers may provide additional
information describing data gaps, data errors and anomolies, and
publication delays.

Modified:

The presence of real-time data on the web enables access to critical time
sensitive data, and encourages the development of real-time web
applications. Real-time access is dependent on real-time data producers
making their data readily available to the data publisher to meet consumer
needs. * Each application real-time access requirements will need to be
evaluated on a case by case basis considering refresh rates, latency
introduced by data post processing steps, **infrastructure availability to
support real-time access, and the data needed by consumers.  *

 In addition to making published data accessible, data publishers may
provide additional information describing data gaps, data errors
and anomalies, and publication delays.
