Preserve attribution and permission evidence for particular recordings and visual treatments.
Asset-specific reuse
Assess reuse against the particular media asset and intended use, without assuming a single rights status for every expression.
- Which performer, producer, designer or commissioning body is documented for this recording or visual treatment? provenance
- What permission evidence covers the proposed playback, reproduction, adaptation or redistribution of this asset? action

What it is Filled
"Mind the gap" is a public transport safety warning directing passengers to take care when crossing the space between a vehicle and a boarding platform.
In scope
- The warning's identity and intended meaning
- Written, spoken and translated expressions of the warning
- The relationship between a warning occurrence and the gap it refers to
- Placement, timing and accessibility of warning delivery
- Versions, provenance and authority of warning content
- Distinction between operational warnings, quotations and titles
Out of scope
- Physical design and maintenance of platforms, vehicles and gaps
- Engineering of loudspeakers, displays and announcement systems
- Complete passenger boarding and alighting procedures
- Named books, films, songs or other works titled "Mind the Gap"
- General models of warning signs and public announcements
- Legal determinations of liability or safety compliance
Why it exists Filled
Enable an agent to recognise, interpret and assess uses of "mind the gap" as a passenger warning, provisionally pending confirmation of the registry entry's intended referent.
Distinguishing features Filled
- An operational use directs attention to a gap associated with a passenger crossing; a decorative quotation does not perform the same function.
- The words alone do not identify the physical gap: their operational interpretation depends on location and delivery context.
- A recording, printed sign and display occurrence can express the same warning without being the same media object.
- A work titled "Mind the Gap" requires its own referent identification and cannot be classified as this warning solely through title matching.
- A translation qualifies through preservation of the warning's intended meaning and action, rather than literal reproduction of the English wording.
What robots and AI may and may not do Filled
Must not
- Misuse the warning in ways that confuse passengers on a real platform.
- Use recordings of the announcement in breach of the operator's rights.
- Mock passengers who need assistance crossing the gap.
Only with a human decision
- Changing safety announcements in a transport system.
May
- Explain the phrase, its origin and its use in public transport.
- Relay the warning to passengers in transport assistance contexts.
Moral aspects Filled
- Platform gaps injure people, especially those with reduced mobility.
- Accessible boarding is a matter of equal access.
Who is affected
- Passengers
- Disabled and elderly travellers
- Transport staff
Owners Filled
Steward
The transport operator that uses it.

- Heard as a recorded announcement at stations.
Capabilities and actions required Filled
- Classify an occurrence as an operational warning, quotation, title or unresolved use.
- Associate a warning occurrence with the crossing and gap it actually addresses.
- Compare spoken, written and translated variants for preservation of meaning.
- Assess whether placement and timing give passengers a usable opportunity to respond.
- Identify missing accessibility evidence and request an appropriate complementary expression.

Hazards and failure modes required Filled
- Ignoring the warning can lead to falls between the train and platform.

Context of use required Filled
- The warning is encountered in announcements and signs where passengers board or leave trains across a platform gap.
- It directs attention to the horizontal space or vertical step between the platform and vehicle, particularly where platform geometry makes boarding uneven.

Open questions
- Does vr.tr.mind-the-gap identify the passenger warning, a particular titled work or another entity?
