Just spoke with @antgonza, and this method is fantastic especially for aligning with redbiom contexts. There are two additional fields that would be invaluable to have:

• platform so we can differentiate between Illumina, 454, etc
• target_gene so we can differentiate between 16S, 18S, etc

It would also be pleasant to have a short command-line safe variant of the algorithm key. For example, artifact 27698 reports "Deblur (Reference phylogeny for SEPP: Greengenes_13.8, BIOM: reference-hit.biom) | Trimming (length: 150)". The whitespace and the "|" would be annoying on the command line. A stable shortname though would be fantastic, something like "deblur_gg138_referencehit_illumina_16S_V4_150nt"
