Use the Tag field to filter objects (with vignettes)

[picheral]

We are about to tag the objects from images which are impacted by a light defect=>

• Objects Tagged 2 should not be included in the computation of the abundances in EcoPart.
• They should not be included in the RAW files too.

Raw files = exported in raw format?

I continue to think they should just be removed from EcoTaxa ... ;-)

And not me if we want the filtering to be done (and possibly re-done) in EcoPart.

Following the standard protocol, UVP acquires images at the first descent and ascent (soak), then during the profile, and finally for 30 m after going back up at the end of the profiles.

There are three reasons to want to not use some of those images:

1. images are outside the actual profile: before firstimgok or after lastimgok
2. UVP is going back up in the water column while if should normally be descending (i.e. when there are strong waves at the surface, etc.)
3. one of the UVP lights is faulty.

I think these three cases can and should be treated the same way:

• zooprocess/UVPapp processes all vignettes
• firstimgok, lastimgok, the switch to remove the upwards parts, and the filtering criterion for faulty lights are set, in zooprocess/UVPapp or in EcoPart (but I think we decided that all these things should be set as early as possible; i.e. it should not be possible to change firstimgok in EcoPart without changing it in zooprocess/UVPapp first, to avoid inconsistencies)
• EcoPart picks the vignettes that are relevant according to those settings (in the general case: are after firstimgok, before lastimgok, are not in an upward part, are not affected by faulty lights) and uploads them to EcoTaxa, together with their metadata. If the sample was already sent to EcoTaxa, EcoPart compares the images present, removes those not needed, adds those needed and pushes the new metadata.

That is: EcoPart is the reference and decides what is and is not in EcoTaxa. EcoTaxa is only there for people to give names to the images.

The alternative is to upload all vignettes to EcoTaxa and then push only the metadata, including the tag, to EcoTaxa upon a change of settings in EcoPart. We need a way to push the metadata so that's easy.

But what I don't like about the solution to upload all vignettes that it puts, in EcoTaxa, images that are essentially useless and therefore creates confusion (and uses ressources un-necessarily). In addition, deleting objects from the API is trivial; uploading new objects will be like uploading the initial profile but with fewer items in it. So I don't think my solution requires much more coding.
