local data validation

boiler has utilities to validate KW18 data. These are offline operations.

# show kw18 help
boiler kw18 validate --help

# validate a single set a kw18 files
boiler kw18 validate examples/kw18/minimal

# find and validate all kw18 files recursively
boiler kw18 validate -r examples/kw18

For this command, it is assumed that all files associated with a KW18 dataset have the same base name and there is only one *.kw18 file per directory.

searching for videos

boiler video search --help
boiler video search --name 2018-03-15.10-35-00.10-40-00.school.G336
boiler video search --scenario basketball --gtag G336

By default, this command will return only the first 20 matches. You can get the next set of results using the --page option.

boiler video search --page 2

downloading annotation data

The following command will download KPF files for one or more videos to the current directory. This will fetch the most recent version of all data as it currently exists in the system (including unaudited annotations).

boiler export video --help
boiler export video 2018-03-15.10-35-00.10-40-00.school.G336 2018-10-15.17-05-00.17-10-00.alb.G333

video pipeline

dispatch annotation tasks to vendors

Once a video exists, it can be transitioned to the annotation state.

boiler vendor dispatch --help

# generate the list of known activity types to file
boiler activity list-types > activity-list.txt

# specify a video, vendor, and list of activities to transition to the annotation stage
boiler vendor dispatch \
  --name kitware \
  --video-name 2999-01-01.00-00-00.00-05-00.admin.G999 \
  --activity-type-list activity-list.txt \
  --set-name test-set
  --annotation-repo-path iMerit/2018-09-06/08/2018-09-06.08-20-00.08-25-00.alb.G229/37-activities

Alternatively, the dispatch can be done after the results have been returned from the vendor. This can be done in bulk as follows:

boiler kw18 dispatch \
  --vendor imerit \
  --set-name testing \
  --activity-type-list activity-list.txt \
  m2-annotations-imerit/iMerit/2018-09-06/*/37-activities

This command also support a --recursive flag to search recursively for kw18 files under each listed path.

vendor activity ingestion

When activities come back from vendors, they should be transitioned to the audit state.

boiler kw18 ingest --help

# list each directory explicitly to ingest
boiler kw18 ingest m2-annotations-imerit/iMerit/2018-09-06/*/37-activities

# or run recursively
boiler kw18 ingest --recursive m2-annotations-imerit/iMerit

Stumpf will first detect whether the files have changed or not. If they have not, no further action will be taken. If they have, then Stumpf will:

• Generate a transition to the "annotation" status
• Run server side validation
  • If validation fails, return failure information
  • If validation succeeds, transition to the "audit" state and ingest activities from the KW18 files

audited annotation ingestion

To dispatch videos to gunrunner, use the following command.

boiler gunrunner dispatch --help
boiler gunrunner dispatch --activity-type-list 47-activities.txt \
  m2-annotations-audit/2018-10-15/08/2018-10-15.08-15-00.08-20-00.alb.G333/47-activities
