If you want OBJECTID to appear due to a schema source, which source's schema is responsible?

• A. Parks MITAB
• B. CommunityMap
• C. All sources
• D. None

Answer: (B)

OBJECTID will appear only when the source schema itself defines a field with that name. In this case, the CommunityMap schema includes an OBJECTID field, so using that schema makes OBJECTID available on each feature. The Parks MITAB schema does not define an OBJECTID by default, so it wouldn’t produce that field from its schema alone. Statements like “all sources” or “none” aren’t accurate because at least one source (CommunityMap) provides the OBJECTID, while another (Parks MITAB) does not.
