An object ID checklist is the fixed set of fields a cataloguer completes the moment an artwork enters the system, before anything else happens to it. At minimum, that means an inventory or object number, title, artist or maker, creation date, dimensions, medium, current location, and a primary image. The number assigned first stays the object’s permanent identifier for its entire life in your collection.

TL;DR:

• Object IDs should be under 10 characters, fixed for life, and stored separately from legacy or secondary numbers to avoid reclassification issues.
• Every record must include at minimum an inventory number, one primary image, artist and creation date, and accurate dimensions with consistent units.
• Linking component records for multipart works with distinct suffixes and detailed installation notes prevents loss of detail and maintains clarity.
• Valuation figures, supporting documents, and sensitive data like purchase prices should be attached directly to each record and marked private when necessary.
• Regular monthly audits using automated filters help ensure all field data remains complete before sale, loan, or exhibition activities.

What Belongs in an Object ID Checklist for Art Records

A complete object record starts with eight fields, and skipping any of them creates gaps that surface later during a sale, loan, or insurance claim. Gallery Systems recommends a unique identifying number, title, artist, dimensions, materials, condition, location, and provenance as the backbone of any catalogue record, built on a relational structure that links each artist to every associated work rather than re-entering the same data twice.

Work through these fields in order:

1. Inventory/object number. Assign this once, at intake, and never reuse or reassign it. Axiell’s cataloguing guidance treats the object_number as the mandatory, primary identifier and routes any legacy or secondary numbers into a separate numbers or digital references panel instead of overwriting the primary field.
2. Title, artist/maker, creation date. Enter the title exactly as the artist recorded it, or as “Untitled” with a bracketed description if none exists. Record the artist’s full legal name consistently across records, and log the creation date as a year or range rather than a guess dressed up as fact.
3. Dimensions. Measure height, width, and depth in a single consistent unit, and note whether the figure covers the object alone, the frame, or both. Multipart works need measurements for each component plus an overall footprint.
4. Medium and classification. Use a controlled vocabulary rather than free text. Terms like “oil on canvas” or “bronze, lost wax cast” should come from a fixed list, not from memory.
5. Current location and location history. Log where the piece lives now, and keep a running history entry every time it moves, whether to a new storage rack or across the country for a fair.
6. Condition summary and handling flags. A short condition note at intake, plus flags for fragility, light sensitivity, or special handling needs, saves a scramble later.
7. Primary image and image reference. Every record needs at least one photo linked before it counts as complete.
8. Provenance and acquisition fields. Source, acquisition date, purchase price, and supporting documents round out the record.

Each field feeds the next. A dimension recorded in inches instead of centimeters, or a medium typed as “oil” one day and “oil paint” the next, breaks searches and reports down the line.

How Short Should an Inventory Number Be?

Keep it under 10 characters whenever the collection size allows it. Short IDs scan faster on barcode labels, fit cleanly on physical tags, and are easier for staff to key into a search box without transcription errors.

• Avoid building classification codes into the number itself. Axiell specifically warns against classificatory components in the primary ID, since a work’s medium or category can be reclassified while the number that identifies it never should change.
• A simple year-plus-sequence format (2026.014) works for most small to mid-size collections.
• A department or collection prefix (P-014 for paintings) works if you never plan to reclassify pieces across departments.
• Store any legacy numbers, gallery consignment codes, or auction house lot numbers in a dedicated alternate-ID panel, never in the primary object number field.

Pro Tip: If you inherit a collection with inconsistent legacy numbering, don’t try to renumber everything at once. Assign new primary IDs going forward, and keep the old numbers alive in the alternate-ID field so provenance trails still connect.

What Image Files Does Every Object Record Need?

A record without a usable image is not a finished record, no matter how many text fields are filled in. CKV’s inventory guidance recommends capturing a full-view shot plus at least one detail image at intake, with additional angles scheduled once time allows.

• Shoot a full front view, a verso or back label view, and one detail shot of any signature, edition mark, or damage.
• Save images at a resolution that holds up printed at roughly 8×10 inches, generally 300 DPI or higher for anything destined for a certificate or catalog.
• Name files with the object ID plus the view, for example 2026.014_front.jpg and 2026.014_verso.jpg, so files sort logically without opening each one.
• Keep the original camera file separate from any cropped or color-corrected derivative, and note who holds copyright on the image itself.
• Add a simple credit line field so photo attribution travels with the file wherever it gets used.

How Do You Catalog Multipart Works and Series?

A diptych, a set of prints, or a modular installation cannot live as one flat record without losing detail on its individual pieces.

• Build a group or master record for the work as a whole, then link individual component records beneath it.
• Record dimensions at both the part level and the overall footprint, since a two-panel piece has three relevant measurements: each panel and the combined span.
• Give each component its own suffix off the master ID (2026.014.1, 2026.014.2) rather than a disconnected number.
• Add installation notes covering spacing, orientation, or assembly order for anything that ships in pieces and gets reassembled on-site.

What Valuation and Document Fields Should a Record Hold?

A record that supports a sale, a loan, or an insurance claim without a follow-up phone call needs more than a price tag.

• Record the latest valuation figure, the date it was set, and where it came from, whether an appraiser, a comparable sale, or an internal valuation method.
• Attach the supporting documents directly to the record: certificates of authenticity, purchase invoices, condition reports, and any provenance paperwork.
• Mark sensitive fields, like purchase price or client contact details, as private, and leave descriptive fields like title and medium public for sharing or listing.
• Use a short valuation-note template that states the method, the date, and any assumptions behind the figure, so a future reviewer knows exactly how the number was reached rather than treating it as gospel.

Gallery Systems recommends attaching acquisition, conservation, and valuation documentation directly to the object record and tagging each field as public or private, rather than storing sensitive figures loose in email threads or spreadsheets that never sync back to the catalog.

Which Data Standards Keep a Collection Searchable?

Field consistency, not field quantity, is what makes a collection searchable five years from now.

1. Decide which fields are mandatory at intake (object number, title, artist, medium, image) and which are optional for later enrichment, then document that split so every staff member follows the same rule.
2. Use controlled vocabularies for classification, materials, and locations instead of free text. Platforms built for serious cataloguing lean on authority files like the Getty’s Art & Architecture Thesaurus for consistent terminology across classification and place names.
3. Write short help text next to each field in the CMS, and hand new staff a one-page data-entry guide instead of relying on tribal knowledge.
4. Run a monthly spot check on 10 to 15 records to catch drift before inconsistent entries pile up across hundreds of works.

How Do You Audit Records for Completeness?

Before a record ships to a client, a lender, or an insurer, run it against a short completeness list rather than trusting memory.

1. Object number assigned and permanent
2. Primary image attached
3. Artist/maker and creation date filled
4. Dimensions recorded with units
5. Medium entered from controlled vocabulary
6. Current location logged
7. Condition summary present
8. Provenance/acquisition source noted
9. Latest valuation and date recorded
10. Supporting documents attached

Most collection-management platforms let you build a saved query or filter that surfaces every record missing one of these fields, turning a manual review into a five-minute report. Escalate any record still missing provenance or a certificate of authenticity to a human review before it goes into a sale or loan packet.

Pro Tip: Run this audit before every art fair, not just once a year. A missing image or an unrecorded valuation date is far easier to catch on a Tuesday morning than during a shipping deadline.

Where Artworksoft Implements These Checklist Fields

Artworksoft’s inventory system mirrors the checklist directly rather than forcing a workaround.

• Short, permanent object numbers with dedicated space for alternate or legacy IDs, following the same short-ID discipline covered above.
• A structured valuation formula that records the figure, date, and method together instead of leaving them scattered.
• Certificate of authenticity generation tied directly to the object record, so documentation and identification stay linked.
• Movement and location tracking across multiple sites, useful for galleries running consignments or loans across more than one location.

A Cataloguer’s Quick Note on Daily Use

Consistent IDs turn intake from guesswork into routine. Assign one staff member as the data owner for each collection segment, and run a short audit weekly rather than quarterly. The habit matters more than the software.

Get Your Checklist Running Faster With Artworksoft

Building this checklist by hand in a spreadsheet works until a collection passes a few hundred pieces, at which point permanent IDs, alternate-number tracking, and valuation history start colliding across tabs nobody remembers to update. Artworksoft is built around exactly the fields this checklist covers: short stable object numbers, linked certificates and invoices, and a structured valuation record that stays attached to the artwork instead of living in a separate file.

The Free Plan lets you set up your first records and test the numbering and image workflow before committing to anything. Galleries and collections that want help migrating existing spreadsheets or legacy numbering into a clean structure can start with the Onboarding & Collection Management Service instead of rebuilding the system alone. Check the pricing page and pick the plan that matches your collection size today.

FAQ

What Is the Minimum Field Set for an Object ID Checklist?

At minimum, a complete object record needs an inventory number, title, artist or maker, creation date, dimensions, medium, current location, and a primary image. Gallery Systems frames these as the backbone fields any relational catalogue record should carry before anything else gets added.

Should the Object Number Ever Change?

No. The object number should stay fixed for the life of the record, and any classification changes belong in a separate field rather than the ID itself, per Axiell’s cataloguing guidance. Legacy or secondary numbers go into an alternate-ID panel instead of replacing the original.

How Many Images Should Each Record Include at Minimum?

A full-view shot plus one detail image covers the minimum, with a verso or back-label shot added when relevant. Additional angles can be scheduled later once resources allow, following the intake approach CKV recommends for new records.

Does Artworksoft Support This Kind of Object ID Checklist?

Yes. Artworksoft’s structure follows the same field logic, including short permanent object numbers, linked certificates, and a valuation record tied to each artwork. Pricing starts with a Free Plan, with a low-cost paid Provenance Plan option available.

How Often Should a Collection Be Audited for Missing Fields?

A monthly spot check on a sample of records catches drift early, while a full completeness audit before any sale, loan, or fair prevents gaps from surfacing at a bad moment. Saved queries or filters in most collection-management systems can surface incomplete records automatically instead of requiring a manual review of every entry.
