ParticipantsFrom

ParticipantsFrom is a field name commonly used in data schemas, databases, and application programming interfaces to indicate the origin or source of a group of participants associated with an event, study, or dataset. The exact meaning depends on the context, but it generally identifies where the participants were recruited or collected from.

In event management, it may specify whether participants came from invitations, self-registration, a registration portal, or a batch import from a customer relationship management system. In research or survey data, it can record recruitment sources such as clinics, online advertisements, referrals, or partner organizations. The field can be a single string or an array of strings, depending on whether multiple sources are allowed.

From a data modeling perspective, participantsFrom is typically a simple attribute on a Participant or Attendance record, or a foreign key to a Source entity. Validation often involves restricting values to a predefined set of sources or codes and normalizing formats to support reporting and analytics.

Privacy and governance considerations include limiting sensitive information, ensuring consistency across systems, and documenting the meaning of each source code to avoid misinterpretation. When exposed via APIs, it is common to define a controlled vocabulary and provide mapping to user-friendly labels.

Example values include online_ad, clinic_recruitment, email_invite, or [online_ad, referral]. See also source, recruitment_source, origin, and data provenance.
