Examples of the video data management rubric applied to published works
| Standards | Example 1 | Example 2 | Example 3 |
|---|---|---|---|
| Example source | van Leeuwen et al. (2015) | Mayerl et al. (2016) | Evangelista et al. (2017) |
| Dryad Data DOI: http://dx.doi.org/10.5061/dryad.r503m. | Data archived at xmaportal.org: unique Study ID Brown40. | Dryad Data DOI: http://dx.doi.org/10.5061/dryad.p68f8. | |
| (1) Data storage | Level 2: Original, archival files on IT-managed storage server (triple backup) at the co-PI’s institution, on DVDs and external hard drives at PI’s and co-PI’s institutions, and cropped images (to reduce file size) on Dryad data repository (not archival). | Level 3: XMAPortal (data repository), storage on Google drive, two external hard drive copies at co-PI's institutions. | Level 2: Maintained in IT-managed storage at UNC, a network accessible lab working copy, and an off-network lab backup; incomplete video set also on Dryad data repository with the kinematics. |
| (2) Video file data | Level 2: Uncompressed original format (tiff images) on Dryad, description of image processing on Dryad (cropping); original uncompressed format (tiffs) on storage server. | Level 3: Original cine files stored in the XMAPortal; XMAPortal interface allows video viewing online, as well as download of videos converted to user-selected formats. | Level 2: Original camera output, in this case the widely accessible .MOV container with h.264 compression. |
| (3) Metadata linkage | Level 1: Metadata of all videos (video format, description of video sequences) available on Dryad as text files (dat and txt format), metadata not bundled with video file, but in a separate metadata folder. | Level 3: Metadata contained within original cine files; metadata downloadable from XMAPortal with same file names as associated videos and bundled into zip archives. | Level 2: Metadata available as plain text on Dryad and in the .MOV container headers; including frame rate, resolution, UTC recording time and GPS location. |
| (4) Video data and metadata access | Level 2: Videos and metadata available on Dryad. | Level 3: Videos and metadata available through XMAPortal; metadata searchable and videos and metadata viewable within the Portal interface. | Level 1: Metadata and an incomplete video set on Dryad; complete video set in a shareable and internet-accessible location. |
| (5) Contact information and acceptable use | Level 2: Contact details and statement provided about how to cite the data on Dryad with CC0 licensing through Dryad and DOI through Dryad. | Level 3: Names, contact e-mails, ORCID IDs and CC BY 4.0 licensing provided in study metadata through XMAPortal; study assigned unique identifier in the XMAPortal. | Level 3: ORCID IDs associated with data in Dryad with Dryad CC0 licensing and DOI through Dryad. |
| (6) Camera settings | Level 1: Metadata documents on Dryad give frame rate and calibration factor (meters/pixel) given in separate file, one file per video recording. | Level 2: Frame rate, spatial calibration, and camera ID available, with some additional information (X-ray settings, shutter speed). | Level 1: Single-camera settings available in file headers; multi-camera calibration and lens distortion data in an internet-accessible location with complete video data. |
| (7) Organism(s) | Level 2: Species and age provided; additional data (size) provided in publication but not on Dryad. | Level 2: Genus, species, size, and individual ID provided. | Level 1: Genus, species provided on Dryad. |
| (8) Recording conditions | Level 1: Date of recording provided; location and context provided only in associated publication, not in the metadata document on Dryad. | Level 2: Date and location of recording provided, as well as environment; people who recorded video available through high level of database menu. | Level 2: Date and location encoded in camera metadata; these plus the environmental context are also provided in the publication. |
| (9) Subject matter/topic | Level 1: Abstract on Dryad. | Level 1: Association of video with project identified through XMAPortal; text description of behavior provided with menu listing of each video. | Level 2: Subject matter, behavior, and original recording purpose described in Dryad metadata. |
