Camtrap DP A frictionless data exchange format for camera trapping data Peter Desmet Ben Norton Jakub Bubnicki TDWG 22 October 2021 0000-0002-8442-8025 0000-0002-5819-9134 0000-0002-2064-3113

- Wildlife monitoring technique - Non-invasive - Well-established - Enables study of animal abundance, distribution, behaviour - Data-intensive: lots of images or videos Camera trapping

- Data management platforms - Upload and manage data - Annotate with species identifications (often using image recognition) - Limited data exchange between platforms - Limited data publication from platforms Data are well-managed, not shared Agouti Wildlife Insights TRAP PER eMam mal

- Does not capture full scope - Project setup - Camera setup - Blank, vehicle, unknown sequences of images - Star schema too limited to capture all relationships - Camera trap researchers do not recognize data model Darwin Core (Archive)? Agouti Wildlife Insights TRAP PER eMam mal Darwin Core (Archive)?

- “Camera Trap Data Package” - Designed to capture all essential data and metadata of a single camera trap study - Model to exchange camera trapping data - Format to exchange camera trapping data Camtrap DP

- Metadata about project Camtrap DP model Project / Study img 1 grey heron img 2 grey heron img 3 blank seq 1 moorhen seq 1 coot gbif.org/occurrence/3045046810 gbif.org/occurrence/3045043163 - Deployments: start/end date, location, camera info - Media: file path/url, timestamp, sequence - Observations: blank, or animal of certain species, count, sex, ...

- Metadata as datapackage.json - Project metadata - Package structure - Deployments as csv - Media as csv - Observations as csv Camtrap DP format datapackage .json media.csv observations .csv deployments .csv sequenceID mediaID deploymentID deploymentID

- Developed by Frictionless Data - Set of open specifications (JSON schemas) that can be combined - Data Package for datasets - Data Resource for data files - Table Schema for table fields - Simple, machine-usable & extensible Using Frictionless Standards specs.frictionlessdata.io

- Open, versioned, collaborative - Camtrap DP profile (extends Data Package) - Project metadata - Spatial, temporal, taxonomic scope - 3 Table Schemas - Fields, definitions, data types, controlled vocabularies - Relationships Camtrap DP development github.com/tdwg/camtrap-dp
