Periodicity
RIXML 2.5 Element
Indicates the regular publication frequency for research products that are issued at fixed intervals. Should only be used for true periodical publications, not for ad-hoc research that happens to be published frequently.
Usage
Apply only to genuine periodicals like "Tech Weekly", "Quarterly Coal Review", or "Today in Tech". Do not use for regular company reports just because they are published daily. Omit entirely for non-periodical content rather than leaving null.
Business Context
Enables consumers to identify and subscribe to regular research series while filtering out such content when seeking focused, event-driven analysis. Critical for research series management and subscription-based distribution models.

Business Rules
Periodicity tags must only be used on reports that are published at regular fixed intervals, not on all reports from publishers who publish daily
Design Decisions
The Periodicity element should only be used on reports that are actually published at regular fixed intervals, not on all reports from publishers who publish daily
This distinction enables consumers to find and subscribe to true periodical content or exclude it when searching for focused, in-depth content
