RFC: Workflow and subject set selection

[beckyrother]

Workflow selection

Possible paths to Classify

From Project Home Page (InVision)

1. Single workflow, no subject set selection
- Click a gold button on project home page to start with a random subject

2. Single workflow, subject set selection
- Click a teal color button with a set selection label to see a modal on top of the project home page allowing for subject set selection

3. Single workflow, subject set selection, subject selection with sequential subject ordering
- Same as above, plus:
- Second screen within modal allowing for subject selection. Messaging within modal indicates that subjects will be sequential.

4. Multiple workflows
- Click the button of the desired workflow to follow one of the above paths. Ideally, workflow options should be divided by workflow selection or not:

From Talk, etc

Clicking Classify in the nav bar will always navigate to a classify interface; however, depending on project setup different things will happen:

1. Single workflow, no subject set selection

• Classify random subject

2. Single workflow, subject set selection
- Go to classify interface, modal opens (the same one as above) to allow for subject set selection

3. Single workflow, subject set selection, subject selection with sequential subject ordering
- Go to classify interface, modal opens (same as above)

4. Multiple workflows
- Go to classify interface, modal opens with workflow selection -> subject set selection -> subject selection (path ends as specified by project)
-

---

From a bookmarked Classify page

1. If workflow, subject set, etc are still active
- Go directly to classifying subject, or open a modal as described above

2. If part of the path is retired
- Redirect to project home page with small popup explaining that the classify page is no longer active and asking to choose a different workflow, etc. InVision

As a project owner, if you've selected the grouped flag for your workflow then we may have to show you the subject set selector regardless. The API request for subjects will fail without a subject_set parameter. We could automatically set that for you but I'm not sure if we should spend much time supporting edge cases. Grouped selection doesn't make sense without a choice of subject sets. Maybe the project builder should prevent you from selecting the grouped option unless your workflow satisfies some requirements, like having more than one subject set?

Will the most common case be a transcription-type project where there's a single workflow, but many subject sets, each representing a volume/file that needs to be transcribed?

How do we support a project that has a single workflow, single subject set, but wants you to select a subject? Basically the case that we're eventually supposed to support for CSSI.

[eatyourgreens]

That's a good question. We have a prototype that allows searching a smallish subject set for subjects (#1925) but searching or browsing all subjects linked to a workflow isn't supported.

[eatyourgreens]

In #1875 I've added /classify/workflow/[workflowID]/subject/[subjectID] as a possible URL for specific subjects.

Any workflow that allows for choice (basically anything that opens a modal rather than going directly to the classify page) should be teal. I think grouped falls under that category, as does the transcription-type project with only one workflow but multiple subject sets
