This glossary defines commonly used terms for the structured data of files. Some of these terms may be new to Commons.

Caption is a short language-specific plain-text description of the contents of a file, analogous to label in Wikidata. Further information: Commons:File captions

Depicts is a special type of statement, using the Wikidata property "depicts (P180)". It is the first suggested property to add to a file without any statements. Further information: Commons:Depicts

Description or probably details (planned feature) is a longer language-specific description of the contents of a file, probably containing some wikitext markup, analogous to description in Wikidata and "description" field in {{Information}} template.

MediaInfo is a type of entity, storing in a "slot" of file description pages. Each file contains one MediaInfo entity, which contains all structured data of the file. If no MediaInfo data is find in a file description page, a virtual MediaInfo entity will be automatically generated.

Prominence is a mechanism for annotating multiple values for a statement. It allows users to improve the results of queries by selecting which values should be included in a search. Prominent statements have a "preferred" rank in Wikibase software behind structured data, where other statements have a "normal" rank. "Deprecated" rank is currently not supported. Further information: Commons:Depicts#Prominence

Statement is a structured way of recording information about a file. A statement consists of a claim, zero or more references (currently not available in structured data), and a rank; a claim in turn consists of a property and either a value or one of the special cases "no value" and "unknown value" (currently they are not supported), and zero or more qualifiers.
