After constructing or editing a workflow definition, the user wants to annotate it with free text to record why they have chosen to use a particular service instance, e.g. BLAST@EBI is faster than BLAST@NCBI, and/or specified a particular service parameter, e.g. BLAST E-value.
An annotation is recorded about the workflow definition that is stored in the MyGridInformationRepository with the appropriate metadata such as date, time, concept type and access permissions.
