Which statement correctly describes the relationship between an Object Set and a Materialization?

• A. An Object Set is a filtered collection; a Materialization is a dataset that reflects the latest state after edits.
• B. An Object Set is the latest state after edits.
• C. A Materialization is a filtered collection created by a search.
• D. Object Set and Materialization are synonyms.

Answer: (C)

In Foundry, you start with a search to define a subset of objects. The live results of that search are an Object Set: a dynamic, filtered collection you can use for exploration and ad-hoc querying, but it isn’t stored as a dataset. A Materialization is the stored representation of those search results—a persistent dataset that captures the filtered view and can be refreshed to reflect changes or edits. So describing a Materialization as a filtered collection created by a search captures that it originates from the search’s results and is then saved as a dataset. This distinguishes the Materialization from the ephemeral Object Set and aligns with how you use both: the Object Set for current, in-memory exploration, and the Materialization for a durable, queryable record of those results. The other statements either mix up which component is dynamic versus stored, or treat them as interchangeable, which doesn’t fit how they’re used in practice.
