At schema.org a person (alive, dead, undead, or fictional) is defined by e.g. other persons, like children, parents, siblings, spouse but also who he or she follows ("The most generic uni-directional social relation") or knows ("The most generic bi-directional social/work relation"). Other properties from person are location related, like PostalAddress, others are more about ContactPoints, like e-mail addresses. The home address is a hybrid Place/Contactpoint.
Schema.org provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognized by major search providers. Search engines including Bing, Google, Yahoo! and Yandex rely on this markup to improve the display of search results, making it easier for people to find the right web pages.
