passageid
Passageid is a term used in software systems to denote a unique identifier assigned to a specific passage of text within a document, transcript, dataset, or collection of texts. The passage may be a sentence, paragraph, or a defined span. The identifier enables precise referencing, retrieval, annotation, alignment with other media, and cross-linking across disparate systems. In practice, passageId is typically stored as a string and may take several forms: a UUID, an incremental numeric id, or a human-readable tag. The important properties are uniqueness within the relevant scope (for example, per document or per project) and stability according to policy. In JSON, passageId is commonly exposed as a field alongside the passage text or metadata, such as: { "passageId": "p-12345", "text": "...", "start": 105, "end": 245 }.
Uses of passageid include indexing large collections for efficient search, enabling fine-grained annotations, aligning transcripts to
Implementation considerations include ensuring consistent generation, avoiding collisions across datasets, and handling passage moves or deletions.
