Determine if and how `link_class_info` will be used in the submission schema

[mslarae13]

slot link_class_info has no guidance or examples.

criteria for completion

• [x] identify how the slot has been used (if at all) in the past, @turbomam provide a query of NCBI?
• [ ] Update nmdc.yaml (or mixs.yaml?) to add more context and examples
• [ ] update NMDC submission portal to match schema slot usage (Mike)

? Leave it out? Not really used... non-actionable DB field

It seems like link_class_info might function like one of the many x_meth fields, which state how the value for slot x was determined. But I can't tell what slot link_class_info might provide context for.

As shown above, the number of biosamples that are annotated with an informative link_class_info is in the low hundreds, out of 35 million. (I am defining informative as something other than a synonym for "not available" or a live web link.)

@mslarae13 I propose that we omit this field from NMDC submission templates. A longer term action could be filing an issue at https://github.com/GenomicsStandardsConsortium/mixs/issues asking for documentation or examples of this term's use. I hope that that request wouldn't be construed as invitation for open-ended discussion about the subject. I suppose it could also be useful to be put in touch with the person who requested that term in the first place.

link_class_info has not been used for any biosamples in the NMDC production MongoDB yet

db.getCollection("biosample_set").find( { link_class_info : { $exists : true } } );

Adding to current sprint per Mark. Need feedback from @mslarae13

-- I agree with this @turbomam

[ssarrafan]

@turbomam can this be closed now that Montana has provided feedback?

[mslarae13]

@ssarrafan I don't think we can close it yet. Steps for resolution are remove from NMDC submission portal. & submit issue to GSC

Ah ok. I thought this ticket was just to "determine if and how..."
I'll move to the next sprint

[mslarae13]

Chris Hunter suggest deprecating this term in GSC. Montana will put an issue into GSC.

@turbomam Should we remove from NMDC now, or wait for GSC update?

[mslarae13]

https://github.com/GenomicsStandardsConsortium/mixs/issues/590

[turbomam]

I'll remove it in 7.6.1

[mslarae13]

@turbomam did this get removed?

[mslarae13]

Currently manually managing. We do not ingest all MIxS slots, see https://github.com/microbiomedata/nmdc-schema/blob/main/assets/import_mixs_slots_regardless.tsv

MIxS that we pull into NMDC schema is 6.0 ..Should pull in 6.2, but some slot changes have been made (names, presence/absence)

• Will require migration
• How/ when with respect to berk? Does it affect postgres?
• There are some no impact changes. samp_collec_meth & device

[ssarrafan]

I'm moving this to the current sprint based on @mslarae13 last comment on 4/29.

[ssarrafan]

@turbomam @mslarae13 should this just be in the backlog? I can remove it from the sprint.

[ssarrafan]

Sprint over, removing from sprint.
