RFC 005: Definition of the term ‘Qualifier’#

Summary#

Specifies qualifiers as the “properties” of live data.

Issue text#

The definition as in SECoP V2016-11-30 draft is not very consistent.

As decriptive data we have:

  • SEC node properties

  • module properties

  • parameters properties

  • command properties

Live data may be: - value - timestamp ‘t’ - sigma ‘e’

It is confusing to use the same term ‘property’ for live data and for descriptive data.

The section with the definition of properties has to be rewritten.

Opinions#

Enrico proposed to name live data like timestamps and sigma qualifiers.

Markus supports this. He would be happy also with a term other than qualifiers, but definitely does not like the terms live properties and descriptive properties, as two different things share the same name.

Decision#

Additional information transported with an update message like timestamps and sigma are called qualifiers.
