归档与合规留存场景: controlled and traceable delivery
`archive-visio-vsd-pdf` is designed for 归档与合规留存场景. The focus is consistent readability, version clarity, and rollback-ready traceability rather than one-off conversion speed. Use pilot validation, staged rollout, and anomaly logging to prevent quality drift.
Compliance archive: package manifest, retention, immutable checksums
- Define the legal or policy minimum package: read-only PDF, source .vsd checksum, export parameter snapshot, owner, and retention class; segregate regulated or litigation holds from everyday folders before bulk conversion.
- Sample-open in the designated archive viewer and print preview; verify watermarks, header versions, and critical IDs. Minor layout deltas with intact meaning should be logged as “known rendering variance” with approver evidence.
- Land packages on WORM, versioned object storage, or a DMS with access logs; schedule golden-file readability reviews yearly or before engine upgrades, reconverting when fonts degrade instead of patching ad hoc.
VSD to PDF (archive) FAQ
Is PDF alone enough for audits ten years out?
Usually not—keep cold .vsd, checksums, and export metadata to prove which revision was published; if policy allows destroying masters, document the waiver and compensating controls explicitly.
Under legal hold, may we mass reconvert legacy drawings?
Confirm with counsel whether that alters evidence form; if allowed, store old and new hashes side by side with rationale—never overwrite the original package without written clearance.
Future viewer upgrades change appearance—is that a compliance risk?
Yes; record the baseline reader and zoom in custody rules, spot-check on new readers, and schedule controlled reconversion with updated metadata when drift becomes unacceptable.
Some pages hold PII—can we archive a redacted PDF only?
Yes if the register notes removed page ranges and legal basis, with approvals retained; keep full-fidelity copies under stricter privacy controls and never reuse outbound names across redacted and full sets.
Third-party audit wants proof the conversion was not swapped mid-flight—what do we show?
Async job ids, storage ETags or object versions, account timelines, and paired VSD/PDF hashes in the manifest—narratives without log fields do not satisfy evidence requests.
