- Introduced custodian_hub_v3.mmd, custodian_hub_v4_final.mmd, and custodian_hub_v5_FINAL.mmd for Mermaid representation. - Created custodian_hub_FINAL.puml and custodian_hub_v3.puml for PlantUML representation. - Defined entities such as CustodianReconstruction, Identifier, TimeSpan, Agent, CustodianName, CustodianObservation, ReconstructionActivity, Appellation, ConfidenceMeasure, Custodian, LanguageCode, and SourceDocument. - Established relationships and associations between entities, including temporal extents, observations, and reconstruction activities. - Incorporated enumerations for various types, statuses, and classifications relevant to custodians and their activities.
