Enable an AI agent to recognise a caravanserai, assess its surviving capacity and condition, and determine appropriate access, use and intervention.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a caravanserai, assess its surviving capacity and condition, and determine appropriate access, use and intervention.
A caravanserai is a purpose-built courtyard lodging compound - typically a rectangular masonry enclosure with a single gated portal, rooms for merchants, and stabling for pack animals - constructed along long-distance overland trade and pilgrimage routes of the Islamic world and neighbouring regions to secure people, goods, and animals overnight.
It can be Assess whether the complex is a caravanserai and record competing identifications.; Reconstruct evidenced routes for travellers, animals and goods through particular historical phases.; Identify areas suitable for access or investigation, subject to current condition and authority.; Assess how proposed reuse would affect caravan-related spaces and their legibility.; Prioritise investigation or conservation of features needed to understand the caravan stop.; Identify missing evidence that prevents a decision about identity, condition or permissible work..
Distinguishing features
Evidence supports organised reception of travelling caravans; a historical name or resemblance to a courtyard inn alone leaves identification provisional.
Accommodation for travellers can be related to provision for pack animals and goods, through surviving spaces or documentary evidence, distinguishing caravan support from lodging alone.
Rooms, enclosures, entrances and service spaces form an identifiable stopping complex rather than merely adjoining a road or market.
Where an enclosure or controlled gateway survives, its relationship to accommodation and caravan handling supports identification; defensive appearance alone does not distinguish a caravanserai from a fort.
Names such as khan, han or ribat are treated as evidence requiring local interpretation, rather than automatically establishing equivalence with caravanserai.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Identity and stopping context Establishes why this complex is identified as a caravanserai and where its stopping function belongs in time and place.
Names, building forms and route associations need to support an identification together rather than substitute for evidence.
Functional identification
Separates evidenced caravan reception from inherited labels and architectural analogy.
Evidence for caravan reception
Records the basis and limits of identifying accommodation for travelling caravans.
- What physical or documentary evidence indicates reception of travelling caravans, and to which period does it apply? provenance
- What distinguishes the evidenced use from an inn, warehouse, market court or fortified residence? definition
Site and route boundaries
Locates the stopping complex within its historical surroundings without absorbing the entire route network.
Extent and route relationship
Records which components belonged to the stop and the evidence connecting it to travel.
- Which enclosures, outbuildings and detached service installations belonged to the caravanserai in each identified phase? boundary
- Which historical routes or settlement connections served it, and what supports those associations? provenance
Arrival and caravan movement Captures how people, pack animals and loads entered, moved through and left the complex.
The ability to receive a caravan depends on connected passages and handling spaces, not simply the presence of rooms.
Gateways and thresholds
Examines entry points, their usable dimensions and their historical control.
Entry capability and control
Relates gateway form and condition to access and the handling of arrivals.
- What are the minimum clearances, level changes and obstructions along each surviving entrance passage? measurement
- What evidence identifies original entrances and any closing, guarding or admission arrangements? provenance
Internal movement and handling
Traces connections among arrival spaces, accommodation, animal areas and storage.
Caravan circulation
Records evidenced movement paths and the spaces available for unloading and holding.
- Which paths connected entrances to animal accommodation, goods storage and traveller rooms in each phase? boundary
- What usable dimensions and gradients constrain movement or unloading in the courts, halls and passages? measurement
Accommodation and provisioning Examines the facilities that allowed travellers, animals and goods to remain at the stop.
A caravanserai model must explain the combined stopping function while distinguishing observed facilities from inferred ones.
People, animals and goods
Assigns supported functions to accommodation areas and records shared or uncertain uses.
Accommodation function
Links room and hall interpretations to evidence rather than assigning uses from position alone.
- What supports identifying particular spaces as traveller lodging, animal accommodation or goods storage? provenance
- Which spaces had shared, seasonal or changing uses, and where must their function remain unresolved? definition
Water and stop services
Records water and other evidenced services supporting occupation of the complex.
Provisioning dependencies
Distinguishes facilities within the caravanserai from supplies or services obtained outside it.
- What evidence identifies water collection, storage, distribution, drainage or animal-watering installations? provenance
- Which evidenced needs, such as food preparation, fodder storage or sanitation, were met inside the complex and which depended on external facilities? boundary
Fabric, phases and condition Assesses how surviving construction and later alterations preserve or obscure the caravanserai arrangement.
The visible complex may combine several periods, and its present condition controls what can be inspected or used.
Construction and alteration
Separates historical phases, losses and reconstruction in functionally important spaces.
Phase-specific layout
Records which gateway, court, room and hall arrangements can be attributed to each phase.
- Which parts of the caravan-serving layout are original to the identified phase, later alterations or modern reconstructions? provenance
- Where have blocked passages, subdivisions or losses changed the relationship between lodging, animal areas and storage? boundary
Deterioration and access
Connects observed deterioration to the usability of specific caravanserai spaces.
Condition-constrained use
Records defects and assessment limits affecting passage through or occupation of the complex.
- What dated observations or assessments describe defects in gateway passages, roofs, walls, courts and water installations? provenance
- Which spaces require restricted access, further assessment or stabilisation before their proposed use? action
Stewardship and compatible use Connects current control and use with decisions affecting the surviving caravanserai.
Physical feasibility alone does not establish authority to act or compatibility with the complex's significance.
Occupation and authority
Identifies present activities and the parties responsible for different parts of the complex.
Use and decision rights
Records who occupies, manages and can authorise changes to caravanserai spaces.
- Who currently occupies or manages the lodging ranges, courts, halls and service areas, and what evidence establishes their roles? provenance
- Whose authorisation and which documented conditions apply to access, recording, maintenance or alteration of each affected area? action
Reuse and functional legibility
Evaluates proposed work against the features that explain the historical caravan stop.
Intervention effects
Examines how changes would affect evidenced circulation, accommodation and provisioning relationships.
- Would the proposed use or intervention remove, conceal or sever evidence connecting arrival, animal handling, storage and traveller accommodation? action
- What investigation or design revision is needed before deciding whether the affected caravanserai features can accommodate the proposal? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Ribat - A ribat is primarily a fortified religious-military frontier post; a caravanserai's programme is commercial lodging (merchant rooms, large stables, unloading court). Some buildings later served both roles, so function and plan, not the name alone, decide.
- Funduq - A funduq is the closely related Maghrebi/Mediterranean warehouse-inn, typically urban and storage-heavy for foreign merchants; a roadside caravanserai is a halt on an overland caravan stage with capacity for large animal trains.
- Urban khan or han - Often used as a synonym; the practical test is siting and stabling: a city khan may lack the water, fodder, and animal capacity of a long-distance roadside station.
- Fortress or castle - Military defence is primary in a fortress; a caravanserai may be fortified but is identified by merchant lodging, a courtyard for unloading, and stables as the core programme.
- Bazaar or covered market - A bazaar is for daytime exchange; it does not provide overnight guarded lodging for caravans and pack animals as its main purpose.
- European coaching inn or post house - Functional analogue for staged travel, but typically rooms around a street-facing yard rather than a single-portal fortified enclosure sized for camel or mule trains.
- Hammam - A bathhouse is often built next to a caravanserai; it is a washing facility, not the lodging compound.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of caravanserai this model covers, and on what evidence? provenance

What the second pass must settle
- What minimum evidence should support caravanserai identification where neither a registry definition nor clear functional documentation exists?
- How should local uses of khan, han, ribat and related terms be mapped to this registry entry without collapsing distinct institutions?
- Which architectural and service variations require explicit alternatives, particularly complexes without a clearly evidenced courtyard or animal accommodation?
- When should detached water installations, markets or lodging annexes belong to the complex rather than remain linked neighbouring entities?
- How can historical accommodation capacity be estimated responsibly when room functions, animal types, seasonal use and operating arrangements remain uncertain?
