Add references to digital object metadata

[bherr2]

Add references support to digital object metadata schema . can be seeded from description fields.

Hi @bherr2, I'm trying to better understand the requirements in this ticket. The ticket description suggests that references should be extracted from the description field. For example, in the ASCT+B Spinal Cord metadata below, the DOI https://doi.org/10.1016/j.neuron.2023.01.00 looks to be the reference that should be extracted and placed in a new dct:references field.

title: >-
  Anatomical Structures, Cell Types, plus Biomarkers (ASCT+B) table for Spinal
  Cord
description: >-
  [Anatomical Structures, Cell Types, plus Biomarkers (ASCT+B)
  tables](https://humanatlas.io/asctb-tables) aim to capture the nested
  *part_of* structure of anatomical human body parts, the typology of cells, and
  biomarkers used to identify cell types. The tables are authored and reviewed
  by an international team of experts.The Spinal Cord v1.0  table focuses on
  lumbar spinal cord cell types from  [Yadav et al., “A Cellular Taxonomy of the
  Adult Human Spinal Cord.”):
  328-344.e7.](https://doi.org/10.1016/j.neuron.2023.01.00) with a companion
  [Human Spinal Cord snRNAseq
  Viewer](https://vmenon.shinyapps.io/humanspinalcord/) which presents a
  cellular taxonomy of the adult human spinal cord using single-nucleus RNA
  sequencing with spatial transcriptomics and antibody validation.

But I recall you mentioned that references should be extracted from the citation and citationOverall fields instead. That said, I’m not entirely convinced that the DOI in the citation field qualifies as a reference, it seems to me more like an identifier for the ASCT+B table itself (see example below). And we already have a dedicated doi field for capturing such values (see here).

Any thoughts?

[bherr2]

Yes, agreed, use the description field

[johardi]

Thanks for confirming! I'll proceed with adding dct:references to the metadata schema and developing a function to extract these references from the description.

@Hrishikesh-3459 will now add references manually to metadata.yaml files
