1. An element data management apparatus, comprising:
processing circuitry configured to:
store, in a memory, at least one piece of element data that includes environment data generated on a basis of sensing data acquired by a tracker and that includes sensing time point data associated with a time range in which an element represented by the environment data is estimated to be present in real space on a basis of a time point at which the element was sensed, wherein the element data includes a link to other element data;
identify, according to environment data generated on a basis of new sensing data, the element data associated with additional environment data constituting a portion or all of the generated environment data;
associate the element data including the additional environment data with the identified element data; and
delete marginal element data, wherein marginal element data corresponds to element data of which the number of links to the element data is a predetermined number or less and for which a time period ranging from a time point indicated by appearance time point data to a time point indicated by disappearance time point data is shorter than a predetermined time period.
