• Human Colossus Foundation (HCF): is a not for profit and releases most of their work product under the GPL, with appropriate product under Apache (due to adoption and derivation concerns).
• Paul Knowles presented OCA- 
  • There is a schema-base (which is the base schema- machine readable semantics of a data structure) which also adds BIT (Blinding Identity Taxonomy or a set of sensitive fields that are blinded through encryption, hiding during presentation etc.),
    overlays on top to enhance or guide the different aspects of the mapping of the schema-base to automatic processing and to present user interfaces these include (but not limited to) mapping, source, subset, label, entry, format etc. This transforms the schema-base into a multi-dimensional array. These schemas are linked to the schema-base using a hash and a pointer to a repository.
  • Meta-data is a part of the data that is managed. The schema and the overlays can add items like source etc.
  • JSON-LD as linked data co-exists with OCA
• Robert Mitwicki demonstrated the way this works at a public sandbox argo.colossi.network. The sandbox has links to available schemas.There were some glitches mainly due to poor internet connectivity; the bane of WFH. However RM did make the whole thing work.
• Paul demonstrated a sample schema-base and various overlays in JSON. This brought clarity to the concepts and showed the succinct nature of the solution.
• Paul also said that most of this work was happening in TOIP Schema WG. 
• He also showed how existing multi-dimensional constructs could be modified to bootstrap new use-cases in new contexts for different enterprises. The presence of a GICs code also showed how meta-data standards could be used to make interoperability work.  
• There was a Q&A
  • How does it work with NIEM schemas? Although NIEM is specific to the US, there would be no problem converting the schemas into this architecture.
  • Any production versions of this? Work was proceeding on getting this into production
  • How do they work with GDPR, especially the data retention for legal purposes? Even if there were disconnects, the relying party could retain data if there overriding constructs.
  • What about other fields (other than healthcare) can this also be applied to data other than Identity data? Yes, work is ongoing for Financial sector under Philippe Page who is the CEO? of HCF.
