Home Movie Metadata: A Minimal Schema Families Can Maintain

Why a Small Archive Needs a Consistent Catalogue

A box of home movies often contains more historical information than its labels reveal. A handwritten year, a surname on a reel tin or a remembered holiday destination may be the only clue connecting a moving image to a family or community. Once reels are digitised and shared as separate files, those clues can become detached from the pictures. Metadata keeps the relationship intact.

Small archive digitisation projects benefit from a catalogue that is simple enough to maintain after the initial transfer. A family should be able to add a new film without learning a specialist database system. A spreadsheet is often sufficient for a modest collection, provided each row represents one identifiable film item and each field has a consistent meaning.

The Core Schema: Twelve Fields for Each Film

A minimal record should identify the item, describe its content and connect it to its physical and digital forms. The following twelve fields provide a practical foundation. More information can be added later without changing the purpose of the core record.

• Item ID: a unique, stable identifier.
• Title: an existing title or a supplied descriptive title.
• Date: an exact date, year, estimated range or unknown.
• Place: the location shown or associated with the film.
• People: identified individuals and their relationship to the collection.
• Description: a concise account of visible events and activities.
• Original format: gauge, film stock information if known, or video carrier.
• Physical location: box, reel number and storage position.
• Digital master: the preservation file identifier.
• Access copy: the identifier of the viewing derivative.
• Provenance: the person or source that supplied the information.
• Notes: condition, uncertainties and relevant editorial decisions.

Dates, Names and Places Need Evidence Labels

Metadata becomes unreliable when an inference is entered as an established fact. A family member may remember that a film shows a wedding in 1962, while the reel itself carries no date. Both pieces of information are useful, but they have different evidential status. Record the proposed year alongside its source and indicate whether it is confirmed, approximate or uncertain.

A practical date convention might distinguish '1962' from 'circa 1962' and '1960-1964'. Avoid entering 1 January as a substitute for an unknown day simply because the spreadsheet requires a date field. If the software requires a standard date value, keep the original descriptive date in a separate field.

Names need similar care. A person visible in a film should not automatically be identified from resemblance alone. Record a name only when there is supporting evidence, and distinguish an identification supplied by a relative from one established through contemporary documentation. For example, 'possibly Margaret, identified by the donor' communicates more than an unqualified name.

Original Formats and Digital Files Must Remain Linked

A catalogue should describe the original carrier as well as the digitised file. A 16mm reel, an 8mm reel and a VHS cassette are not interchangeable descriptions. Record the gauge or carrier where known, the reel or tape identifier and any visible stock or label information. Unknown technical details should remain blank or be marked as unknown rather than supplied through assumption.

Digital preservation requires a relationship between the source item and its files. Give the preservation master and viewing copy distinct identifiers, then record their formats and locations in the catalogue or an associated file register. For example, a film with item ID HM0042 might have a preservation master named HM0042_PM and an access copy named HM0042_AC. The identifiers should remain stable even if the files move between storage systems.

Record the date of digitisation, the organisation or person responsible and any significant processing. If a film has undergone stabilisation, colour correction or scratch removal, describe the work in the technical notes. The catalogue does not need to contain every operational detail, but it should make clear that the digital presentation differs from the original material.

A Local History Film Project Needs Shared Naming Rules

When several families contribute material to a local history film project, inconsistent naming quickly becomes a retrieval problem. One contributor may enter a village name in its modern form, another may use an older spelling and a third may record a nearby landmark. Establish preferred place names while retaining historical variants as alternative terms. This allows researchers to search across different forms without erasing the language used by contributors.

Use a controlled list for recurring values such as film gauge, digitisation status and date certainty. Keep free-text descriptions for narrative detail. Agree on how to record unknown people, uncertain dates and multiple locations before collecting records from different households. A short written catalogue guide can prevent incompatible entries from accumulating.

For a shared project, designate one person to maintain the master catalogue and establish a procedure for submitting corrections. Contributors should be able to explain where new information came from. A correction to a person's identity, for instance, should include the contributor and the reason for the change.

• Agree on one format for dates and identifiers.
• Maintain preferred and alternative place names.
• Record the source of contributed information.
• Keep a change history for substantive corrections.

Maintenance: A Catalogue That Can Survive Its Creator

A minimal schema is useful only if someone continues to maintain it. Store the catalogue in a location covered by the collection's backup arrangements and retain periodic exports in a widely readable format such as CSV. A spreadsheet saved only on one person's laptop is a fragile catalogue, even if every field is carefully completed.

Review the catalogue whenever a new derivative is created, an original reel is moved or a previously unidentified person is named. Do not attempt to complete every field before digitisation begins. A record with a reliable identifier, known carrier and clear uncertainty labels is more useful than a detailed record filled with guesses.

Start by assigning identifiers to the first ten films in the collection. Enter the twelve core fields, leave unsupported information blank and connect each item to its physical location. Once those records are consistent, use the same template for the remaining reels.
