System, cataloguing
and research

Pictoria One is a cataloguing and research system for visual collections and heritage archives. It brings records, digital assets, sources, authorities, rights and institutional decisions into one working environment.

It serves image collections, archives, museums, universities, research projects, galleries and specialist collections that work with complex visual material and documented context.

Intake, Catalogue, Explore and Knowledge are four connected working spaces. The catalogue model, Semantic Framework, access policy and managed files provide the shared structure beneath them.

The domain includes works of art, photographs, negatives, slides, scans, reproductions, documents, buildings, places and related digital material. Each installation uses an application profile suited to its collection.

Pictoria distinguishes the work or object, the visual document that represents it, the managed Digital Asset and the concrete files held in storage. People, places, events and sources remain identifiable records of their own.

Getty, Wikidata, Iconclass and other sources retain their canonical identifiers, authorship and scope. The institution defines where and how each authority is used in its catalogue.

The Pictoria Local Thesaurus is reserved for demonstrated gaps or divergences that suitable external authorities do not adequately cover.

Alternative attributions, dates, identifications and classifications retain their own sources and review states. The institution establishes a current catalogue treatment without erasing earlier or competing readings.

It is the intellectual architecture that defines how records and concepts can be related, what each relation means and how its source, responsible act, catalogue treatment and revision history remain available.

The relation type, documentary source, responsible act, date and current catalogue treatment remain distinguishable and available for review.

They operate at different levels. The Framework covers relations between records, concepts, sources and catalogue treatments. A thesaurus is one terminological component used within that architecture.

Mappings express a reviewed relation between concepts while preserving the identity and scope of each authority. A mapping is not treated as identity unless that stronger relation is justified.

Knowledge uses governed relations and retrievable sources to investigate connections across the collection without changing the accepted catalogue record.

The system distinguishes the intellectual work or object, the visual document that depicts it, the managed Digital Asset, its representations and each concrete file and storage location. These resources remain related without being collapsed into one image record.

Pictoria operates locally or in a privately hosted environment, with infrastructure, geographic location, retention and storage policies defined for each institutional installation.

Access depends on organisation, role, scope, record status and rights. Editing catalogue data or administering accounts does not automatically grant access to preservation masters.

Originals and preservation masters remain separate from access copies and thumbnails. Each file has its own identity, integrity checksum, registered location and access rules. Independent copies, scheduled integrity checks and rehearsed restoration support recovery.

Pictoria records authentication, privilege and workflow events. Destructive preservation actions require explicit approval, activity records and recovery controls.

Approved services support extraction, reconciliation, visual observation and research. Their suggestions retain their origin and review state until an authorised person evaluates them.

Processing policy distinguishes closed institutional processing, private hosting and explicitly approved external use. Collections and records carry additional restrictions where required.

Preservation masters sit outside routine external processing. An approved external service receives only records or derivatives eligible for the defined purpose and policy.

Pictoria uses explicit entities, stable identifiers, linked authorities and portable catalogue data. Export and migration profiles adapt records to each source system, standard and destination.
