description: "Physical device with digital connectivity used by a heritage custodian\nto enhance visitor experience, monitor conditions, or provide services.\n\n**WHY IOT CLASS?**\n\nModern heritage institutions increasingly deploy IoT devices:\n- **Beacons**: Location-based triggers for mobile apps\n- **Kiosks**: Interactive information terminals\n- **Sensors**: Environmental monitoring (climate, light, visitor counts)\n- **Displays**: Digital signage, interactive screens\n\nThese are a form of DIGITAL PRESENCE that bridges physical and digital worlds.\n\n**RELATIONSHIP TO OTHER DIGITAL PRESENCE TYPES**:\n\n```\nDigital Presence Hierarchy:\n\nDigitalPlatform (PRIMARY - websites)\n \u2502\n \u2514\u2500\u2500 AuxiliaryDigitalPlatform (SECONDARY - project sites)\n\nSocialMediaProfile (THIRD-PARTY - external platforms)\n\nInternetOfThings (PHYSICAL-DIGITAL - in-venue devices) \u2190 THIS CLASS\n```\n\n**SOSA/SSN ALIGNMENT**:\n\nW3C Semantic Sensor Network (SSN) and Sensor, Observation,\
\ Sample, \nand Actuator (SOSA) ontologies provide the semantic foundation:\n\n- `sosa:Platform` - Entity hosting sensors/systems (building, room, beacon)\n- `sosa:Sensor` - Device that observes properties\n- `sosa:Observation` - Act of observing a property\n- `ssn:System` - System comprising multiple components\n\n**USE CASES**:\n\n1. **Visitor Experience Enhancement**:\n - Bluetooth beacons trigger app content near artworks\n - NFC tags on object labels for detailed information\n - Interactive kiosks for self-guided exploration\n \n2. **Environmental Monitoring**:\n - Climate sensors (temperature, humidity) for conservation\n - Light level sensors to protect sensitive materials\n - Air quality monitoring in storage areas\n \n3. **Visitor Analytics**:\n - People counters at entrances\n - Heat maps of gallery traffic\n - Dwell time sensors near exhibits\n \n4. **Digital Signage**:\n - Rotating information displays\n - Exhibition schedules\n - Wayfinding\
\ screens\n\n**EXAMPLE - Museum with IoT Devices**:\n\n```yaml\nCustodian:\n identified_by: \"https://nde.nl/ontology/hc/nl-nh-ams-m-rm-q190804\"\n preferred_label: \"Rijksmuseum\"\n iot_devices:\n - device_id: \".../iot/rijksmuseum-beacon-gallery-1\"\n device_name: \"Gallery of Honour Beacon Network\"\n device_type: IOT_BEACON\n device_count: 24\n coverage_area: \"Gallery of Honour (main wing)\"\n purpose: \"Proximity triggers for mobile app content\"\n \n - device_id: \".../iot/rijksmuseum-climate-monitor\"\n device_name: \"Conservation Climate Monitoring\"\n device_type: IOT_SENSOR\n device_count: 150\n coverage_area: \"All galleries and storage\"\n purpose: \"Temperature and humidity monitoring for preservation\"\n publishes_to: \"https://dashboard.rijksmuseum.nl/climate\"\n```\n\n**TEMPORAL CONSIDERATIONS**:\n\nIoT devices have installation/decommissioning dates:\n- Beacons may be temporary for exhibitions\n- Sensors\
\ may be upgraded/replaced\n- Kiosks may be moved between venues\n\n**NOT INCLUDED**:\n\n- Smartphones/tablets (user devices, not custodian-owned)\n- Standard IT infrastructure (servers, networking)\n- Security cameras (unless part of heritage experience)\n"
