Interoperability
Descriptions export into a recognized documentary exchange format rather than staying captive to the application.
Institutions and archives
Photographic collections documented to heritage standards.
Museums, archive centers, galleries, and schools are not looking for a production tool. They are looking to describe, prove, and pass on.
In short
An institutional photographic collection requires normalized description, traceable provenance, and proof of integrity over time. Obscura Flow provides persistent inventory numbers, structured indexing, Dublin Core export, SHA-256 manifests, Ed25519 signatures, and scheduled fixity audits.
- Persistent inventory numbers independent of file names
- Structured indexing: who, what, where, when, how, why
- Dublin Core export for documentary exchange
- Provenance and location history for works
- Authenticity certificates, portfolios, and catalogues raisonnés
- Scheduled fixity audits and verified restore
Evidence
Description
A consistent indexing grid across records, a precondition for reliable cross-collection search.
Evidence
The archive signature provides a verifiable element to attach to a preservation report.
Describe to make searchable
An incomplete record makes an item invisible. Consistency of description matters more than its richness.
- Structured indexing
- The who/what/where/when/how/why grid imposes the same axes on every record.
- Controlled vocabulary
- The thesaurus prevents competing synonyms from fragmenting search results.
- Persistent identifiers
- An inventory number stays valid after a rename, a move, or a migration.
- Normalized export
- Dublin Core makes it possible to feed a union catalog or an external portal.
Prove integrity over time
A preservation report that asserts without measuring commits nobody. Checks must be repeatable and dated.
- Manifest
- The SHA-256 digest of every file establishes the reference state.
- Scheduled audit
- Periodic recomputation catches silent corruption before it spreads to copies.
- Format validation
- Files whose future readability is at risk are identified before it is too late.
- Verified restore
- Extraction checks the signature and protects existing files from being overwritten.
Provenance and documentary output
For a work, the chain of ownership and exhibition history are part of the item itself.
- Provenance
- Origin and successive transfers are documented alongside the image.
- Location history
- The successive locations of a work remain consultable.
- Catalogue raisonné
- Bodies of work can be exported as a structured catalogue.
- Certificates
- Authenticity certificates and portfolios are produced from existing data.
Questions
Is it suitable for heritage institutions?
Yes. Persistent inventory numbers, structured indexing, Dublin Core export, provenance, and reports support photographic collections.
How is archive integrity verified?
Each archive includes a SHA-256 manifest and an Ed25519 signature. Scheduled fixity audits and format validation reveal drift or corruption.
How often should an archive be verified?
A quarterly fixity audit is enough to catch silent corruption before it propagates into backups. Scheduled audits remove the need to remember.
Are EXIF/IPTC/XMP metadata supported?
Yes. They are read through ImageIO, and ExifTool when available, and underpin cataloging, search, migration, and preservation.
What happens if I stop using Obscura Flow?
Your originals never left your disks, and metadata is written to XMP sidecars, a standard format other tools can read. Archives remain packages accompanied by their manifest: nothing depends on the application still being installed.
