separators in concatenated fields

[sckott]

in the dcsubject field, the keywords seem to be just concatenated without a separator, e.g. "BEHAVIOUR CHANGEBLINDNESSBULLETINCENTER FOR HEALTHCHILD HEALTHCLINICAL PRACTICECOMMERCIAL SEXCOMMERCIAL SEX WORKERSCOMMUNICABLE DISEASES...".

best for okmaps would be if they were separated with ; (edited)

same goes for dccreator

[sckott]

and some other fields, reworking this to parse better
