I just had a look at ResumeRDF.

    Class: cv:Person

    Person - CV subclass of WordNet person

    in-range-of:	cv:aboutPerson cv:referenceBy
    in-domain-of:	cv:gender cv:birthPlace cv:hasCitizenship cv:hasNationality cv:maritalStatus cv:noOfChildren cv:hasDriversLicense

It's probably a bad idea to encourage people to list protected characteristics on a CV / resume. Employers (except vary rare exceptions) can't use this information so there's no point including it.
